Both ways of looking at the history of logic as well as some of the issues that plague contemporary disputes over the nature of logic are illustrated in three recent books. Henry Veatch's Intentional Logic turns to a medieval Aristotelian philosophy as providing the framework for an adequate account of logical subject matter. Ernest Moody's Truth and Consequence in Mediaeval Logic borrows from the technical apparatus of present-day logicians in an endeavor to reassess what was once (...) dismissed as fourteenth century logic-chopping. Benson Mates' Stoic Logic is a similar study in the logic of an earlier period. (shrink)

Criteria for the transtemporal identity of composite artifacts are best understood in terms of functions, histories, and the intentions their makers. As long as certain background-conditions are fulfilled, composite artifacts can undergo changes in all of their parts with no breakdown in their identities, even to the point of being unrecognizable as sharing their identities with themselves as they were originally constituted. They can be repaired, modified, or improved without a resulting breakdown of transitivity. I defend this view against views (...) according to which there must be some limit to how much change artifacts can undergo while still retaining their identities, against views according to which any changes result in breakdowns of transitivity, and against views according to which there are no criteria of identity over time.

Bevir's doctrine of ?weak intentionalism?, developed in the course of his criticism of the work of Quentin Skinner, at once modifies and qualifies Skinner's approach by specifying the beliefs of individuals rather than their utterances as the loci of their intentions and the things that fix the meaning of their utterances. This has the effect of broadening the scope of meaning, by disengaging the meaning of utterances from their status as speech acts, of narrowing the relevance of linguistic contexts, by (...) denying that historians are required to study those contexts in order to understand the intended meaning of texts, and of blurring the historicity of texts, by suggesting that the utterances of which they are comprised may mean different things to author and audience. The paper draws attention to ambivalences in Skinner's position that Bevir does not take into account, and draws out continuities in Skinner's thought that Bevir's narrative does not register.

Paperback. The intention of this book is to set forth the history (up to the end ofthe 17th Century) of logical and rhetorical reflections on dilemmaticarguments, i.e. arguments in which from each member of an exhaustivedisjunction of premisses an identical conclusion is drawn. Certain types ofsuch arguments were widely discussed among ancient teachers of rhetoricand, to a lesser extent, by ancient logicians. After a period of relativeneglect in the Middle Ages, there was a remarkable revival during theRenaissance. In the (...) 17th Century, several attempts were made to find theproper logical form of dilemmatic reasonings. In the course of tracingthese developments, special attention is paid to the consequentiamirabilis, a kind of argument in which a conclusion is inferredfrom a premiss that is its direct contradictory.

This paper interprets Kant's theory of right on analogy with his theory of truth. The familiar distinction is presented between the mental act and its object: e.g. between the act of believing and the belief; the perceiving and the thing perceived; the act of willing and the action willed. The act of mind is always private; different people, however, can perceive and believe the same or contradictory things. The notion of truth depends (for Kant) on the intersubjectivity or universalizability of (...) the mental object. It might seem that the act intended as well as the act of intending must be private, however, because I can will only my own actions; but Kant suggests that I may will not as myself but as one of a community: the logical subject of the intending may not be I but We. Kant had in mind the community of rational beings; Bradley and Green relativize the community to national groups. (shrink)

Five purposive relations are investigated: endeavoring, endeavoring for a certain purpose, bringing something about in a certain endeavor, bringing something about for a certain purpose, and bringing something about intentionally. No satisfactory analysis of these terms has yet been proposed, either in mentalistic -- belief, desire, intending -- or in action terms. While bringing something about for a certain purpose may seem too obscure to be taken as a primitive, there are at least two arguments in favor of it. First, (...) no analyses in terms of other primitives has worked; second, the rather natural definitions of the other notions which it makes possible take us some way toward understanding the structure of intentional action.

According to Kant, the division of the categories “is not the result of a search after pure concepts undertaken at haphazard,” but is derived from the “complete” classification of judgments developed by traditional logic. However, the sorts of judgments that he enumerates in his table of judgments are not all ones that traditional logic has dealt with; consequently, we must say that he chose the sorts of judgments in question with a certain intention. Besides, we know that (...) his choice of judgments and categories is strongly influenced by certain views of natural science that he fully accepts. For this reason, his argumentations are sometimes seriously inconsistent. As to Kant’s argumentations of categories, many problems have already been pointed out, but in this paper, I take up the categories of quantity and quality once more, and make clear his argumentations’ hidden logic and its distortion from the point of view of the history of logic and natural science. First, I confirm that there are non-negligible problems in his explanation to the effect that his derivation of the categories of quantity and quality is based on the quantity and quality of judgments. Next, I reconsider the meaning of his treating the categories of quantity and quality as pure concepts of the understanding. Finally, I conclude that by having recourse to the categories of quantity and quality Kant tried unjustly to apriorize the distinction between the “extensive magnitude” and “intensive magnitude” that has a long formational history since Aristotle.

This paper explores the close connection in early phenomenology between the problem of objectless presentations and the concept of intentional objects. It clarifies how this basic concept of Husserl’s early phenomenology emerged within the horizons of Bolzano’s logical objectivism, Brentano’s descriptive psychology, Frege’s mathematical logicism, Twardowski’s psychological representationalism, and Meinong’s object theory. It shows how in collaboration with these thinkers Husserl argued that a theory of intentionality is incomplete without a concept of the intentional object. It provides a brief history (...) of the concept of intentional objects in the philosophical logic of the nineteenth century that demonstrates its relevance to the problem of objectless presentations in the early phenomenology of the twentieth century. It suggests that Husserl accepts Bolzano’s objectivism and Frege’s logicism, rejects Brentano’s conception of immanent objects and Twardowski’s notion of representational pictures, and ignores Meinong’s theory of objects. Thus the paper employs the formation of Husserl’s concept of the intentional object to enhance the understanding of the historical and philosophical relationships between early phenomenology and contemporaneous philosophical movements.

Modern social theory, by and large, has aimed at reducing the complexity of action situations to a set of manageable abstractions. But these abstractions, whether functionalist or linguistic, fail to grasp the indeterminacy of action situations.Action proceeds by discovery and combination. The logic of action is serendipitous and combinative. From these characteristics, a number of consequences flow: The whole field of our intentions is engaged in each action situation, and cannot really be understood apart from the situation itself. In (...) action situations we remain aware of the problems of categorization, including the dangers of infinite regress and the difficulties of specifying borders and ranges of categories. In action situations, attention is in permanent danger of being overwhelmed. We must deal with many features of action situations outside of attention; in doing so, we must entertain simultaneously numerous possibilities of action. Emotional expression is a way of talking about the kinds of possibilities we entertain. Expression and action have a rebound effect on attention. "Effort" is required to find appropriate expressions and actions, and rebound effects play a role in such effort, making it either easier or more difficult.Recent theoretical trends have failed to capture these irreducible characteristics of action situations, and have slipped into a number of errors. Language is not rich in meanings or multivocal, except as put to use in action situations. The role of "convention" in action situations is problematic, and therefore one ought not to talk of "culture." Contrary to the assertions of certain theorists, actors do not follow strategies, except when they decide to do so. Actors do not "communicate," in the sense of exchanging information, except in specially arranged situations. More frequently, they intervene in the effortful management of attention of their interlocutors. Dialogue, that is, very commonly becomes a form of cooperative emotional effort.From these considerations, it follows that the proper method for gaining social knowledge is to examine the history of action and of emotional effort, and to report findings in the form of narrative.

In this short, dense essay, Jean Cavaillès evaluates philosophical efforts to determine the origin - logical or ontological - of scientific thought, arguing that, rather than seeking to found science in original intentional acts, a priori meanings, or foundational logical relations, any adequate theory must involve a history of the concept. Cavaillès insists on a historical epistemology that is conceptual rather than phenomenological, and a logic that is dialectical rather than transcendental. His famous call (cited by Foucault) to abandon (...) "a philosophy of consciousness" for "a philosophy of the concept" was crucial in displacing the focus of philosophical enquiry from aprioristic foundations toward structural historical shifts in the conceptual fabric. This new translation of Cavaillès's final work, written in 1942 during his imprisonment for Resistance activities, presents an opportunity to reencounter an original and lucid thinker. Cavaillès's subtle adjudication between positivistic claims that science has no need of philosophy, and philosophers' obstinate disregard for actual scientific events, speaks to a dilemma that remains pertinent for us today. His affirmation of the authority of scientific thinking combined with his commitment to conceptual creation yields a radical defense of the freedom of thought and the possibility of the new.

The present study aims at giving factual support to the thesis that the Parmenides is serious in intention, rigorous in logical demonstration, and stylistically meticulous in its original composition. While this consideration may be tedious, still it is useful. Against a past history which has claimed to find the tone hilarious, the logic fallacious, the work inauthentic, the text in need of bracketing by divination, the whole incoherent— against these eccentricities a certain firm sobriety seems called for. I (...) hope that my conclusions find support and persist through fluctuations of philosophic and philological styles.The main difficulty with my thesis is that the text as we now have it (in Burnet's and Dies' editions) shows exceptions to every rule that might apply to style and even to logical structure. Thus it is almost but not quite uniformly true that each theorem opens with a theorem statement; that each is marked by a "questioning" response; that each deduction is valid when formalized in propositional calculus; and so on. Are the exceptions the result of careless composition; are they deliberate warnings not to take the proofs too seriously; or are they the result of errors in transmission? One way to test this is to reconstruct early versions of the text: if these show more logical rigor than the later versions the notion of a wholly valid original is supported; if they do not, the result may point toward the need for a less serious interpretation. A second thing to look for is the possibility that, here and there, parts of a coherent original text are uniquely conserved in sources other than the principal mss, B,T, and W. This assumes, of course, that the "original" text in question is the one with the best logical form, and that assumption seems justified. As a matter of fact, later copyings almost universally show deterioration, not improvement in style and logic.My textual findings are more compatible with some lines of interpretation than with others. Thus I offer some reasons for not accepting treatments of the work as a joke, mystical revelation, or abrupt metaphysical revision. The structure of the dialogue is best explained, I think, by reading it as an indirect proof that some non-Platonic interpretations of the theory of forms are unsatisfactory. In particular, these are the Megarian version (represented in the first part of the dialogue by Zeno, in the second by the First Hypothesis), and the Anaxagorean version put forward by Eudoxus (represented in the first part by Cephalus and his friends from Clazomenae, in the second by the Second Hypothesis). At the same time, the dialogue shows the need for a philosophic method other than the "hypothetical— deductive" way of dianoia; presumably this other method is the "dialectic" discussed in Republic VII. It also follows that any interpretation of the Phaedo which falls into either the Eudoxian or Megarian difficulties was not— at least at the date of the Parmenides—Plato's intended reading.Findings concerning the relations and reliability of the manuscripts of this dialogue also apply to the texts of the other Platonic dialogues which these mss contain.Further, the Parmenides is such an important work both historically and intrinsically that any insight which textual study can bring to its interpretation is a contribution to Western philosophy.

Contemporary philosophers of history and interpretation theorists very often deny the thesis of intentional realism, because they reject intentionalism or the thesis that an agent's or author's intentions are relevant for the interpretive practice of the human sciences. I will defend intentional realism by showing why it is wrong to whole-heartedly reject intentionalism and by clarifying the logical relation between intentionalism and intentional realism. I will do so by discussing the two central arguments against intentionalism; the argument from the perspective (...) of narrative anti-realism and the epistemic argument focusing on the fact that an agent's or author's intentions are not epistemically accessible in a direct manner. In particular, I will show that the fact that historians write narratives does add a level of complexity as far as the giving of explanations of individual actions are concerned. Yet it does not follow that the explanatory power of a full fledged historical narrative can be understood as being completely independent of our folk psychological account of individual agency. Accordingly, we should also be prepared to accept a methodological distinction between the human and the natural sciences as long as the human sciences use the folk psychological framework for explanatory purposes, since it is only in the former that empathy plays an epistemically central role. I however do not claim that empathy is the only method of the human sciences nor do I claim that all interpretive disputes can be settled merely in light of our empathic capacities. (shrink)

Finally, the first book started Peirceana. Peirceana is expected as a new series that provides access to both Peirce’s mostly unpublished late works and secondary papers, in which ideas of this American philosopher are developed. This edition is opened with three volumes on Peirce’s manuscripts on “Logic of the Future.” The thinker gave this definition to his theory of existential graphs, i.e., a diagrammatical logical project that includes three sections. The sections can roughly correspond to propositional logic, first-order (...) logic and modal logic. The theory of existential graphs is a particular conception. It predicts ideas of proof theory, mathematics of continuity, and cognitive sciences. Besides, it has an impressive philosophical foundation and perfectly emphasizes the importance of diagrammatic notations. Since many writings are published here for the first time, the edition per se is a significant event for the history of logic. However, Peirceana can do more than this. It urges to think of how the logic of 20‒21st centuries would have looked like if Peirce’s intentions were discovered earlier. At the same time, it clarifies the ground for contemporary investigations. Today we have a bunch of papers about various non-classical modifications, extensions, restrictions, and applications of the original theory. Peirceana is projected as the publication that can gather specialists (logicians, philosophers, as well as IT and cognitive science scholars) who are interested in the development of Peirce’s approach. It lets the readers reconsider our ordinary logical conceptions (e.g., reasoning, logical and language analysis, and others) as well as the conventional understanding of the evolution of modern logic. The current paper has two objectives: firstly, it estimates this diplomatic partly critical edition with its several thoroughly elaborated introductions, and secondly, it briefly introduces the existential graphs theory. A set of examples demonstrates the basic principles of this system. (shrink)

A Buddhist-Christian Logic of the Heart explores the philosophies of Being and Nothingness as expounded in the Buddhist and Christian point of view with particular emphasis on the socioethical implication that all human beings, despite vast differences in history, language, and culture, share the cognitional, intentional makeup as emphasized by Nishida and Lonergan.

Hegel's Philosophy of History can be characterized as Eurocentric and one finds in it many problematic passages, and even racist statements, as well as a legitimization of colonialism which is presented as a means of education (Bildung). Nevertheless, this article argues that it is possible to reject such judgements and at the same time hold on to the basic intention of Hegel's theories of freedom and Bildung. While the concept of freedom as self-determination is certainly applied in a Eurocentric (...) manner by Hegel in his Philosophy of History, this concept is not Eurocentric at its core. To understand this ‘core’, one has to go back to Hegel's logic of the concept, which finally leads me to a concept of ‘concrete Bildung’. The struggles for self-determination of the colonized peoples must be understood in terms of a further development of the realization of the concept of freedom. If one wants to think Hegel's Philosophy of History meaningfully beyond Hegel's own time, one is inevitably led to the necessity of a liberation of the colonized, for there is a need for a further extension of the consciousness of freedom that actually is inclusive. This demand is contained in Hegel's thought itself, but it still remains abstract with him and must therefore be developed beyond him. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 127 from Adam, and inheriting "real sins" with real "guilt." From his De libero arbitrio onward, Augustine sees that if Adam's is the sin of someone "other" than ourselves, then it is alienum to us, is simply not "our" sin, and we cannot be held "guilty" of it. On the other hand, he is willing to accept that God might fittingly decree that Adam's descendants "inherit" the (...) debt, obligation, weakness, sickness, or mortality (choose the Augustinian metaphor you prefer) that is appropriate punishment for the sin which Adam (personally) committed. But, at bottom, Rigby and Sage have the same difficulty: both assume that Augustine was a "creationist," when he was not. For he saw that creationism must necessarily view our individual souls as metaphysically "other" than Adam's, so that God could never judge us guilty of that "other's" sin. Rigby would have been wiser to combine and extend the insights he himself quotes from Huftier (59 n. 14), Bonner (78-79: omnes fuimus ille unus), TeSelle (86), Confessions 4.31 ("by our own act": nos inde ruimus), and Rondet (121 n. 6). Augustine thought that we sinned the original sin (nos inde ruimus) precisely because we were metaphysically identical with our father Adam: fuimus iUe unus. I submit that the very same theory, making our souls identical with Adam's, subtends both the Confessions and Augustine's anti-Pelagian writings. ROBERT J. O'CONNELL Fordham University Mark D. Johnston. The Spiritual Logic of Ramon LluU. New York: Oxford University Press, 1987. Pp. x + 336. $65.oo. In the last twenty-five years a considerable number of scholars have turned their attention to the sort of formal logic found in the writings of the Catalan polymath, Ramon Lull (d. x316). This attention has run parallel to the current interest in medieval logic and linguistic theory, although Lull was less concerned with the theory of the properties of terms than with formulating a realistic theory of the predicables and categories and a new theory of demonstration. In the work under review Mark Johnston provides us with a study of Lulrs logic which is systematic in character. His work represents a first attempt to go beyond the studies of individual points of doctrine and to situate the development of Lulrs logic within the context of the evolution of the Ars lulliana. The work is divided into two parts. The first part analyzes the early writings to the year 13o3, the second the later ones composed between 13o3 and 1316. Johnston takes the very early Compendium logicae Algazelis as his point of departure for the first part and the Logica nova of 13o3 as that for the second part. He describes Lull's thought following the sequence of the different tracts of the Aristotelian logic and relates its development to the biography of the Majorcan philosopher. Throughout his study Johnston emphasizes three special characteristics in Lull's approach: its popular nature, its extreme realism, and its moralizing intention. Lull's works were composed both in Latin and in Catalan and aimed at an audience quite different than that of the clerical universities of the Middle Ages. His approach as- 128 JOURNAL OF THE HISTORY OF PHILOSOPHY 28"1 JANUARY 199o sumed a natural ontology, realist and "essentialist," which was of Avicennian derivation. His argumentation presupposed the idea that individual beings are concrete realizations of abstract essences situated in a scala creaturarum which leads in degrees to the divinity. The idea of basing philosophical discourse on the hierarchical structure of creation appealed to Lull because in it he found something common to the Christian, Jewish, and Islamic traditions. This fact made his logic necessarily an extremely realist one, consciously opposed to the logic of the Scholastics. From the extreme realism of Lulrs logic to his moralizing intent, it is but a step. To explain the status of things as real, Lull formulated a tropological exegesis of creation by way of the scala creaturamtm. Johnston accordingly directs our attention to the importance of analogy in Lull's logic. The analogical character of Lulrs logic had indeed been emphasized by the brothers Carreras y Artau in their history of Spanish philosophy... (shrink)

This paper approaches the intentional structure of the emotions by considering three claims about that structure. The paper departs from the Brentanian and Husserlian ‘priority of presentation claim’. The PPC comprises two theses: intentional feelings and emotions are founded on presenting acts and intentional feelings and emotions are directed specifically to the value-attributes of the presented objects. The paper then considers two challenges to this claim: the equiprimordial claim and the priority of feeling claim. The EC asserts that the presentational (...) and affective dimensions of intentional feelings and emotions are equiprimordial. I respond to this challenge to the PPC by revising it, claiming instead that the founding relations exist between the presentational and affective senses in an experience whose presenting and affective aspects are equiprimordial. The PFC grants priority to the affective, a grant which presupposes the independence of the affective from the presentational. I argue that the PFC is mistaken, and that the revision of the PPC can handle the examples on which the PFC is based. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and History, Customs and EthicsHui-Chieh Loy (bio)Origins of Moral-Political Philosophy in Early China: Contestation of Humaneness, Justice, and Personal Freedom. By Tao Jiang. New York: Oxford University Press, 2021.Tao Jiang's Origins of Moral-Political Philosophy in Early China is a serious tour de force of a study. In many ways, I am reminded of Angus Graham's Disputers of the Tao and Benjamin Schwartz' The World of Thought in Ancient (...) China—but updated. A signal difference is that it is more constrained in its coverage of figures, texts, and especially in having the topical focus upon moral-political philosophy. At the same time and within the chosen (narrower) confines, it often examines its subject in greater detail and draws on more recent discussions.One neat thing that Jiang does is to deliberately weave in explicit discussions of how each subsequent thinker or text incorporated or criticized ideas associated with earlier thinkers. (I formulated it this way since there isn't enough historical evidence about who-actually-read-what in the ancient world, citation practices being what they were.) In this regard, I am especially heartened to read, for example, the sections on "Traces of Mohist Elements in the Laozi" (3.3.2), and "Mohist Elements in Han Feizi's Thought" (7.3.3).By no means should the desultory remarks below be counted as a full review or assessment (impressionistically, this is the sort of book I will recommend that my grad students read—there, I've said it). Think of them as humble shards of pottery thrown in the hope for some jade in response. To make my task more focused, I will comment on the Sinology versus Philosophy distinction, and Jiang's treatment of the Mohists.I. Philosophy and History of PhilosophyAn important part of Jiang's Introduction is devoted to discussing the situation of Chinese Philosophy as a field in the Western Academy, caught between Sinology on the one hand and academic Philosophy on the other. Due to the different scholarly objectives and norms in the two disciplines, scholars working on Chinese Philosophy often find themselves caught [End Page 420] between two distinct audiences who demand different things. Jiang's aim is to propose an "interpretive model to distinguish two sets of scholarly objects operative in Sinology and philosophy. These objects are related and at times overlap, but they are also often irreducibly distinct, i.e., original text versus inherited text, historical author versus textual author, and authorial intent versus textual intent, with the former in the pairs belonging to Sinologists and the latter to philosophers" (p. 7). In general, I am highly sympathetic to the distinctions Jiang draws. But I do wonder if we need to step back and start from a wider context involving what is potentially a deeper divide.Now, it is entirely a caricature but the joke around the water cooler is that philosophers—especially those of a more "analytic" bent—often exude the attitude that they are not in the business of reading old books. Their project is one focused on issues and problems and puzzles that are ultimately about the natural and human world, rather than about texts and their interpretation, or even the historical thinkers themselves. To give some obvious examples, the intellectual questions they see themselves as answering are the likes of:• Can we know that God exists, if God exists at all?• What is the nature of moral claims? Do they admit of truth and falsity?• How is causation related to possibility?• Is a logic that dispenses with the law of non-contradiction viable?• What are the necessary and sufficient conditions of knowledge?• Is abortion morally justifiable?Sometimes the questions they ask even infringe on the results and insights from nearby fields, for instance linguistics and the natural and empirical sciences:• What is time?• Can a presentist conception of time be made consistent with contemporary physics?• What is the nature of consciousness? How is it related to physical neural states or informational computational processes?• Can computers be sentient?• How is morality related to the passions?• In what sense is a political order that does justice to diversity of moral beliefs...

This article contrasts Mark Bevir's approach to the history of ideas with a neo-Gramscian theory of discourse. Bevir puts the case for an ‘anti-foundationalist’ approach to understanding ideas, yet he defends a weak rationalism centred on individual intentions as the original source of all meanings. Discourse theorists—specifically Ernesto Laclau and Chantal Mouffe—also adopt an anti-foundationalist perspective but pursue its implications beyond any rationalism. The advantages of discourse theory are argued to lie in its emphasis on power and conflict in the (...) consitution and transformation of social meanings and identity. Laclau and Mouffe's work, it is claimed, alerts us to a political logic of discourse that Bevir's more rationalist approach to ‘ideas’ sidesteps. (shrink)

This book about philosophical and methodological problems in psychoanalytic theory is surely one of the best pieces of literature on this subject of recent vintage. The author, a psychiatrist on the faculty of Harvard Medical School, displays considerable logical skill and philosophical sophistication, in addition to the expected familiarity with the psychoanalytic literature. The major purport of the book is a logical and philosophical defense of the claim that psychoanalytic explanations of human behavior--if constructed with proper and adequate regard for (...) relevant clinical data--are methodologically sound and genuinely scientific. One useful and novel feature of Sherwood's argument is the particular type of illustrative case material which he employs: instead of mustering various bits and instances of behavior from large numbers and varieties of cases, Sherwood considers the psychiatric explanation actually given by Freud in one of his recorded clinical case histories--the famous "Karl Lorenz" or "rat man" case. Sherwood devotes two chapters to a detailed description of this case, and an analysis of the logic of Freud's explanations of the behavior presented therein. From the point of view of logical and methodological considerations, there is an obvious advantage in such an approach, for it enables the critic to avoid leveling charges against the theory which might originate simply from extracting portions of explanatory material from their proper context. Sherwood also includes a chapter of criticism of what he calls "the thesis of the separate domain"--the view that there are fundamental differences in the logic of explanations of human behavior, cognition, and other phenomena involving reasons and intentions on the one hand, and other forms of explanation characteristic of the physical sciences, on the other. Philosophically, this is the most mature chapter of the book, and will be of interest to philosophers of mind, as well as philosophers of science, particularly for its criticism of the views of R. S. Peters. Unfortunately, however, Sherwood's argument is not unmarred by serious flaws and deficiencies. These include a highly psychologistic analysis of the logic and structure of explanation whose subsequent use repeatedly involves the author in context-of-discovery vs. context-of-justification confusions. Moreover, an apparent lapse into a non-Humean account of causality in the second section of the fifth chapter leads Sherwood to an unfortunate petitio principii on the issue of causes vs. reasons. Sherwood's critical discussion of the classical "covering-law" model of scientific explanation in the penultimate chapter exhibits numerous failures to come to grips with the essential aspects of the Braithwaite-Hempel-Oppenheim theory. Finally, an important sin of omission: Sherwood completely ignores the highly germane and decisive issues raised by authors such as Nagel and Arthur Pap, who charge the theoretical concepts of psychoanalysis with lack of cognitive and empirical significance. In sum, this is a flawed but eminently worthwhile book in the philosophy of behavioral science.--H. P. K. (shrink)

After a brief history of Brentano's thesis of intentionality, it is argued that intentionality presents a serious problem for materialism. First, it is shown that, if no general materialist analysis (or reduction) of intentionality is possible, then intentional phenomena would have in common at least one nonphysical property, namely, their intentionality. A general analysis of intentionality is then suggested. Finally, it is argued that any satisfactory general analysis of intentionality must share with this analysis a feature which entails the existence (...) of a nonphysical "level of organization".

As used by professional logicians today, is the name of their chosen subject singular or plural, "logic" or "logics"? This is a special case of a more general question. For instance, an algebraist might write a book entitled "Algebra", which is about algebras. Though many mathematicians are not aware of it, logic today most decidedly has its plural aspect. Indeed, it always did. Classical logic, which mathematicians often tend to identify with the entirety of logic, was (...) in place roughly by the beginning of the twentieth century. Since then a wide range of so-called non-classical logics have been developed. But indeed, before the creation of classical logic, there were multiple versions of logic, some of them more-or-less formalized. The current growing interest in medieval and ancient European and Asian logics has brought much of this back to modern awareness. Perhaps a later volume in this series will look at the history from a contemporary viewpoint. But that is not our task here. This is the second volume in a series called Landscapes in Logic. The intention of the series is to present reports illustrating the interplay between contemporary work in logic and mainstream mathematics. Of course this is both vague and overly ambitious, and must result in heterogeneous collections. The first volume in the series, Contemporary Logic and Computing, appeared in 2020. The contents divided plausibly into topics from contemporary logic, and from contemporary computing. The present volume is more diverse, and includes articles about both classical and non-classical logics, sometimes from the semantic side and sometimes from the proof-theoretic side. Some articles are primarily technical, often algebraic, while others are more philosophical in nature. Many fit into multiple categories. This multiplicity should not be seen as a defect. The papers here do not just explore logics house by house, but say something about their general neighborhoods as well. (shrink)

The framework of conceptual realism provides a logically ideal language within which to reconstruct the medieval terminist logic of the 14th century. The terminist notion of a concept, which shifted from Ockham's early view of a concept as an intentional object to his later view of a concept as a mental act , is reconstructed in this framework in terms of the idea of concepts as unsaturated cognitive structures. Intentional objects are not rejected but are reconstructed as the objectified (...) intensional contents of concepts. Their reconstruction as intensional objects is an essential part of the theory of predication of conceptual realism. It is by means of this theory that we are able to explain how the identity theory of the copula, which was basic to terminist logic, applies to categorical propositions. Reference in conceptual realism is not the same as supposition in terminist logic. Nevertheless, the various "modes" of personal supposition of terminist logic can be explained and justified in terms of this conceptualist theory of reference. (shrink)

Explanation of and commentary on Hegel’s Logic in English is rare and much needed. The Logic has been given far less attention than the Phenomenology, and such treatment as it has had from such writers as Stace, Findlay, Kaufmann, and Taylor has not always been adequate and has at times been misguided. The expectant reader will, therefore, approach Professor Burbidge’s book with high hopes. These, however, are at once mitigated by his confession that he gives only fragments of (...) a commentary, and, further, his approach is professedly and intentionally subjective and so one-sided. Nevertheless, a fresh look at the Logic is much to be welcomed if it can offer new insights and make Hegel more understandable and more acceptable. But, alas, this book hardly fulfills even the promise of its title. Fragmentary it certainly is, and not only in the sense intended by the author. The commentary is limited to the first major triad of each of the three main divisions of the Logic, omitting the second and the third triads in each case. This is singularly unfortunate because the very nature of the dialectic is such that the outcome always provides the explanatory principle of what precedes: the end is the explanation of the process, as well as the complete and adequate presentation of the prior, partial, and relatively obscure concepts which constitute its moments. Commentary restricted to the first portion of any section, therefore, is liable to miss the real significance of the whole doctrine. (shrink)

The intention of this essay does not, I fear, readily fit into any of the previous categories of ethical or moral philosophy. I am not concerned here with the Good, with values, or with the question of their recognition, foundation, and justification; nor am I concerned with duties and virtues. The linguistic and/or logical structure of ethical judgments, too, is outside my subject, as is the problem of Free Will.

The aim of the paper is to consider the narrative that Philipp Frank’s decline in the United States started in the 1940s and 1950s. Though this account captures a kernel of truth, it is not the whole story. After taking a closer look at Frank’s published writings and at his proposed book, one can see how he imagined the reunion of logical empiricism. His approach was centered on sociology and on the sociological aspects of science and knowledge. As I will (...) argue, Frank’s longstanding interest in the reunion of the sciences and the humanities can be detected in his sociology and philosophy of science as well as in his reading of Carnap’s critique of metaphysics. But Frank’s intention was never fully recognized, partly due to the atmosphere of American philosophy and sociology in the second half of the twentieth century. As a result, his conception of unified science and logical empiricism died with him. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Deleuze, Bergson, Merleau-Ponty: The Logics and Pragmatics of Creation, Affective Life, and Perception by Dorothea E. OlkowskiElodie BoublilOLKOWSKI, Dorothea E. Deleuze, Bergson, Merleau-Ponty: The Logics and Pragmatics of Creation, Affective Life, and Perception. Bloomington: Indiana University Press, 2021. 180 pp. Cloth, $63.00; paper, $28.00[End Page 152]Dorothea E. Olkowski's latest book carefully examines "the relationship between the creation of ideas and their actualization in relation to semiology, logic (...) and the cosmos in the philosophies of Deleuze, Bergson, and Merleau-Ponty." However, this work is neither an extensive or historical account of Deleuze's, Bergson's, and Merleau-Ponty's philosophies, nor an attempt to homogenize their views on space, time, or perception. Instead, it subtly compares their differences and similarities to move beyond metaphysical dualism, and fruitfully rethinks the relations between formal logic and ontology. Indeed, the author aims to draw a "theory of form," based on the logic of sensation, ultimately designed "to take the place of a theory of the real, of material physical forces."Chapter 1 retraces the history of postmodernist claims and their philosophical legacy. Olkowski explains that postmodernism is not first and foremost a political worldview or a debunking of objectivity in natural sciences. Instead, "it begins as a formal system or series of formal systems." Olkowski explores how Deleuze draws on the knowledge of modern science and logic (Bolzano, Cavaillès) and on Bergson's critical analysis of it to elaborate his logic of sensation. Bergson's conception of affectivity impacted Deleuze's and Merleau-Ponty's theories of corporeality and sensation, and their understanding of perception. Bergson's concept of "body image" specifically influenced Deleuze's elaboration of the concept of "movement-image," through which he tried to overcome the dichotomy set up by mind–body dualism.Chapter 2 focuses on Deleuze and Guattari's critique of logic as an attempt to find a third way between idealism and materialism and to overcome the disconnection between formal logic and lived experience. It reviews their critique of Euclidean geometry, their objections to formal logic as set out by Frege and Russell, and their assessment of phenomenology in order to eventually show Deleuze's affinity with Peirce's pragmatist approach. Then, the author aims to determine if Deleuze's attempt could be compatible with the phenomenology of Merleau-Ponty and Bergson's understanding of quality and multiplicity.Chapter 3 focuses on Bergson. Recalling the controversy with Russell, Einstein, and Langevin, Olkowski refers to Merleau-Ponty's defense of Bergson's concept of intuition to prove the accuracy of his reflection on creative forces and pure duration. As she explains, "[T]he intent here is to clarify the relations between these different aspects of Bergson's thought and draw out how Deleuze makes use of these structures derived from Bergson's philosophy." This leads her to explore, more specifically, how Deleuze reworks the concept of "multiplicity" along the lines of Bergson's analysis of the élan vital.In chapter 4 the author focuses on Deleuze's work on cinema to deepen the philosophical correlation between Bergson's concepts, Deleuze's analysis, and the influences of Merleau-Ponty and Pierce. It aims to rethink the relation between movement and time, notably through the notions of time-image and movement-image. Olkowski notably showcases Deleuze's concept of destiny, "which is the pure power of time that [End Page 153] overflows all possible reaction. It defeats, immobilizes, and petrifies figures in their own affectivity; it sends them to their fate, destroying conventions along the way. For Merleau-Ponty, as for Bergson, acts are still possible in a network of temporal relations so that motion and time are destiny but differently than for Deleuze."Chapter 5 addresses the Phenomenology of Perception and how Merleau-Ponty provides an opportunity to rethink perception. In this book and his Courses on Nature, Merleau-Ponty "does not dismiss either position—that of objective science or that of the natural attitude—but argues that although each contains an element of truth, it is perception and only perception that allows us to bridge the gap between physical reality and behavior/comportment." Deleuze will depart from... (shrink)

In the first part of this paper Hugh Rayment-Pickard challenges Mark Bevir's assumption that Derrida does not care about historical or other kinds of truth. A consideration of Derrida's early work on Husserl shows deconstruction to be a kind of skepsis or epoche launched in search of the truth. Yet deconstruction reveals the truth as ‘undecidable’, which means that Derrida's commitment to the truth must take the form of ‘faith’. The second part of the paper considers an example of definite (...) intentional meaning given in Mark Bevir's Logic: Petrarch's ascent of Mont Ventoux. On examination, Petrach's motivation can be seen to be radically divided between secular and religious concerns, a split vividly illustrated in his imaginary dialogue with St Augustine: The Secret. Finally, Rayment-Pickard looks briefly at Derrida's own dialogue with St Augustine, ‘Circumfession’, which also argues that human intentions are irreducibly complex and plural. (shrink)

In this article I want to outline an argument for a New Critical Theory with a cosmopolitan intent. Its main purpose is to undermine one of the most powerful beliefs of our time concerning society and politics. This belief is the notion that “modern society” and “modern politics” are to be understood as society and politics organized around the nation‐state, equating society with the national imagination of society. There are two aspects to this body of beliefs: what I call the (...) “national perspective” of social actors, and the “methodological nationalism” of scientific observers. The distinction between these two perspectives is important because there is no logical co‐implication between them, only an interconnected genesis and history. (shrink)

The paper’s main objective is to bring out the original project of philosophy and history of science, underlying the famous works of Thomas Kuhn. In defiance of what is commonly envisaged, the model of scientific revolutions is demonstrated as a promising conceptual frame to be used with the purpose to reconstruct the development of modern and contemporary science. The analysis of the logic of explanation of scientific changes elaborated by Kuhn is based on two canonical monographs: The Structure of (...) Scientific Revolutions and Copernican Revolution. It is argued that the standard, widespread interpretation of the model, assuming the drastic conceptual cuts to occur as a result of a paradigm change, is essentially untenable. In fact, the model implies that each change leads to the higher level order and is susceptible to rational reconstructions. Kuhn’s conception is subsequently confronted with Stefan Amsterdamski’s notion of ideal of science, with the intention of showing that the reversal of the relationship between explanans and explanandum as established inaforementioned works would have damaging consequences in terms of reconstructive attempts in history of science. It is shown that what is of most value in Amsterdamski’s workis indeed strictly Kuhnian in character. (shrink)

How do historians approach objectivity? This is addressed by Mark Bevir in his book The Logic of the History of Ideas by his argument for an anthropological epistemology with objectivity in the historical narrative resting on the explanation of human actions/agent intentionality equating with meaning. The criticism of this position is at several levels. As sophisticated constructionists historians do not usually ask ‘Can history be objective?’ Rather, they work from the balance of evidence reflecting the intersubjectivity of truth and (...) they acknowledge the problematic nature of inferring agent intentionality and the difficulties in equating this with ‘what it means’. Why Abraham Lincoln issued the 1863 emancipation proclamation is a case in point. No historian would claim to have located its true meaning objectively in effect doubting Mark Bevir's claim that ‘objective knowledge arises from a human practice in which we criticise and compare rival webs of theories in terms of agreed facts’ . There are also further challenges to an over-reliance on rational action theory and the problems associated with the selection of evidence. Equally, most historians in practice doubt objectivity emerges from an accurate knowledge of the motives that can be matched to weak authorial intentions and that this leads to action via decisions. Few historians today accept that their narrative mimics past intentionality and that this provides true meaning. The article offers four reasons for rejecting Bevir's position and concludes with a defence of the narrative-linguistic determination of meaning. This suggests that history is subject to the same narrative and imaginative constraints as other forms of realist writing, rather than being privileged by an access to knowable intentionality and that this constitutes objective historical knowledge.

One can sympathize with [Leo] Strauss' ultimate aim—to protect the validity of moral judgment against that form of relativism which would assess the value of great philosophic works simply in terms of how they satisfied the needs of the times for which they were written. But in believing that "historicism " meant "relativism," and that all attention to the temporal relevance of great doctrines in the history of ideas was somehow perverse, Strauss was profoundly mistaken. Hermeneutics is not axiology. Questions (...) of truth and validity are fundamental, but they are dependent upon a prior solution of the problem of meaning. And for the establishment of meaning, contextual analysis is crucial. For it is not as if ideas were the ghostly inhabitants of another world, logically cut off from human purposes and intentions. All three things exist: ideas, agents, and social contexts, and the best history of ideas is, I believe, constituted by the careful consideration of the multiple interrelationships between them. It is false to believe that texts exhaust their own meaning. For there is always an historical grounding and a web of person and social events that give them wider and deeper significance. And this is precisely why we must ask such questions as: What sort of society was the author writing for and trying to persuade? What were the conventions of communication and the literary forms of discourse current at the time? What was the author's class affiliation, his place in the social hierarchy of his age? And perhaps above all: What were his moral commitments, the structure of his ideals?

Quentin Skinner has enduringly insisted that a past text cannot be ‘understood’ without the reader knowing something about its historical and linguistic context. But since the 1970s he has been attacked on this central point of all his work by authors maintaining that the text itself is the fundamental guide to the author’s intention, and that a separate study of the context cannot tell the historian anything that the text itself could not. Mark Bevir has spent much of the (...) last 20 years repeating a similar counter-argument. Although ‘study the linguistic context’ might be a useful heuristic maxim, Bevir says, it does not express a necessary or sufficient condition for understanding. But Skinner is right, and one of the figures he has consistently identified as a formative inspiration, R. G. Collingwood, has already (in his work of the 1930s) shown why. What Collingwood calls his ‘logic of question and answer’ explains why the historian cannot answer his characteristic ‘intention’ question about past texts without knowing the context of problems to which authors think they are offering solutions. The study of context is neither ‘prior’ (as Bevir incorrectly supposes) nor ‘separate’ (as Skinner inaccurately says), but it is, as Skinner maintains, nevertheless impossible to grasp an author’s intention without it. This ‘logic of question and answer’ also explains why, in history, dismissing the study of context is in fact a pre-judgement of evidence yet unseen. (shrink)

This work aims to foster interest in the links between a particular theoretical and conceptual development of sociological science in Italy and the debate surrounding the history of scientific subjects, here called the epistemological history of various disciplines. The author sets out to trace the points of view emerging from Italian epistemological sociology between the early twentieth and twenty-first centuries and related to the debate on the historical and philosophical sciences. The intention resides in revealing the distinctive characteristics of (...) the latter, their internal (logical and methodological) rather than external (historical and social) factors, while investigating the task of the new historians of science confronted with the changes caused by various knowledge and forms of technological know-how. The text provides the contemporary scientific community with a new route to follow when seeking to rationally establish and write the history of sociology. The addressees are, more than anything else, the new generation of scholars of the history of science. (shrink)

In this paper I argue that Bolzano's concept of deducibility and Tarski's concept of logical consequence differ with respect to their philosophical intent. I distinguish between epistemic and ontic approaches to logic, and argue that Bolzano's deducibility presupposes an epistemic approach, while Tarski's logical consequence presupposes an ontic approach.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge History of Seventeenth-Century Philosophy by Daniel Garber, Michael AyersDonald RutherfordDaniel Garber, Michael Ayers, editors. The Cambridge History of Seventeenth-Century Philosophy. 2 vols. Cambridge: Cambridge University Press, 1998. Pp. xii + 1616. Cloth, $175.Over a decade in preparation, this latest addition to the Cambridge History of Philosophy is an enormous achievement—both in its size and the contribution it makes to redefining [End Page 165] the landscape of (...) seventeenth-century philosophy. The editors make no bones about their intention to rewrite the history of early modern philosophy, reversing the trend dominant through much of this century of reading seventeenth-century philosophers in the light of twentienth-century “interests and preconceptions” (4). As they note, the movement to historicize our understanding of seventeenth-century philosophy has been underway for some time in the English-speaking world, furthered in many cases by contributors to these volumes. From this perspective, the present work represents, if not the culmination, at least a progress report on these efforts and the success they have achieved.As in previous volumes of the Cambridge History, the subject matter is treated thematically. Consistent with their larger goal, the editors have further attempted to organize the volumes in a way that remains faithful to the expectations of the period. Part I sets the stage with chapters that establish the larger social and historical context: “The institutional setting” (Richard Tuck); “The intellectual setting” (Stephen Menn); and “European responses to non-European culture: China” (D.E. Mungello). For the rest, the editors write, “the structure of the collection corresponds to one way, at any rate, in which an educated European of the seventeenth century might have organized the domain of philosophy” (2). First comes logic (including method and general ontology); then, the primary categories of being (God, body, soul); finally, the basic operations of the soul (understanding, will, action), whose treatment comprehends the topics of epistemology and ethics.Part II, “Logic, Language, and Abstract Objects,” opens with three short chapters by Gabriel Nuchelmans that survey the terrain of seventeenth-century logic according to the traditional divisions of term, proposition/judgment, and argument. These are followed by contributions on “Method and the study of nature” (Peter Dear); “Universal, essences, and abstract entities” (Martha Bolton); and “Individuation” (Udo Thiel).The discussion of metaphysics proper begins in Part III with the most fundamental being: God. Included here are chapters that examine specific theological issues—“The idea of God” (Jean-Luc Marion); “Proofs of the existence of God” (Jean-Robert Armogathe); “The Cartesian dialectic of creation” (Thomas M. Lennon)—as well as ones that deal more broadly with the crucial connection between philosophy and religion: “The relation between theology and philosophy” (Nicholas Jolley) and “The religious background of seventeenth-century philosophy” (Richard Popkin).Part IV, “Body and the Physical World,” forms the single largest part of the book and its intellectual core. It opens with two chapters—“The scholastic background” (Roger Ariew and Alan Gabbey) and “The occultist tradition and its critics” (Brian Copenhaver)—that effectively mark out the boundaries of the “new philosophy” that emerges in conjunction with the development of seventeenth-century science. These are followed by a series of chapters that examine particular features of that philosophy: “Doctrines of explanation in late scholasticism and in the mechanical philosophy” (Steven Nadler); “New doctrines of body and its powers, place, and space” (Daniel Garber, John Henry, Lynn Joy, and Alan Gabbey); “Knowledge of the existence of body” (Charles McCracken); “New doctrines of motion” (Alan Gabbey); “Laws of nature” (J.R. Milton); and “The mathematical realm of nature” (Michael Mahoney). [End Page 166]The final section of Volume I takes up the third main category of being: “Spirit.” It begins with Daniel Garber’s overview of the positions of the major figures, “Soul and mind: Life and thought in the seventeenth century,” followed by chapters on “Knowledge of the soul” (Charles McCracken); “Mind-body problems” (Daniel Garber and Margaret Wilson); “Personal identity” (Udo Thiel); and “The passions in metaphysics and the theory of action” (Susan James).Volume II of the History is devoted to topics that, in one way or another, elaborate operations of the soul.

At APr 2.4 57a36–13, Aristotle presents a notorious reductio argument in which he derives the claim ‘If B is not large, B is large’ and calls that result impossible. Aristotle is thus committed to some form of connexivity and this paper argues that his commitment is to a strong form of connexivity which excludes even cases in which ‘B is large’ is necessary. It is further argued that Aristotle’s view of connexivity is best understood as arising from his analysis of (...) affirmation and negation in terms of combination and separation: a proposition that separates two terms cannot entail a proposition that combines the same two terms. In order to motivate this account of connexivity, this paper interprets Aristotle as emphasising the predicative structure, especially the copulae, of the argument’s component propositions. The arguments for this are based on a consideration of the larger context of APr 2.2–4. A reconstruction of the argument using propositional variables does not fully capture Aristotle’s intentions.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:After Gödel: Platonism and Rationalism in Mathematics and LogicMark C. R. SmithRichard Tieszen. After Gödel: Platonism and Rationalism in Mathematics and Logic. Oxford-New York: Oxford University Press, 2011. Pp. xi + 245. Cloth, $75.00.Tieszen’s new book offers a synthesis and extension of his longstanding project of bringing the method of Husserl’s phenomenology to bear on fundamental questions—both epistemological and ontological—in the philosophy of mathematics. Gödel held Husserl’s (...) philosophy in high regard, and thought that it offered the most promising avenue for an adequate understanding of the foundations of mathematical thought and practice, but Gödel himself did not give a full systematic statement of how phenomenology might carry out that project. Tieszen takes up the task in this book, which is structured around two main guiding themes. The first is to locate the sources of Gödel’s philosophical views—principally [End Page 303] in Plato, Leibniz, and of course Husserl, along with Kant as a sort of backcloth—and the second is to argue that from these materials, a promising rationalism in mathematics and logic can be consistently articulated. Along the way we also encounter a good many of Gödel’s arguments against an array of reductive positions, Hilbert’s formalism and Carnap’s “logical syntax” project among them, as well as arguments against the prospects of a mechanical or purely computational understanding of the human mind. Many of the arguments (both negative and positive) stem from a reflection on the consequences of Gödel’s landmark incompleteness results of 1931.The core of Tieszen’s positive proposals comes in chapters 4, 5, and 6: here is where we meet with “constituted Platonism,” Tieszen’s name for the rationalist, realist synthesis of Husserl’s method and Gödel’s mathematical insights. Methodologically, the starting point is the actual practice of mathematics as a human undertaking, and its conditions of possibility. At the most general level, it is characteristic of thought to be intentional, that is, to be (or try to be) about something, to have a target, to be a bearer of meaning. So it goes for thought about items in sensory awareness, about fictional objects, or about mathematical subject-matter. Concerning the latter, what we encounter in mathematical experience are frequently “phenomena that resist our will, so that we are ‘forced’ in certain directions” (170); what accounts for this resistance to our will are invariants, which have the further characteristics of repeatability—both for a single subject, and among many subjects—and availability for convergence (221), which, I take it, means availability as structures or concepts upon which many independent rational investigators will come to rest. Thinking mathematical thoughts is quite unlike thinking thoughts about fictional items, because fictions are indefinitely plastic in the face of human will. It is also unlike thought about sensory items, in that the intentional objects at issue are not available to outer sense; but from another angle it is more like thought about real material items than imaginary beings, because our mathematical thoughts are exposed to the possibility of error or misrepresentation in various ways. (An elementary example: most people think that 1 is distinct from 0.9999... repeating: this is a misrepresentation, because they are in fact identical.)The phenomenology of mathematical practice is such that we assay various conjectures and proposals about invariants already given to consciousness by previous practice, and discover what further invariant structures or concepts are revealed as necessary constraints upon the various possibilities that we can experimentally float for ourselves. Sometimes our conjectures or intentions are fulfilled, sometimes they are frustrated; but it is the very fact of fulfillment and frustration which points us to a Platonic reality. It is not the noumenal realm of the “naive” Platonist, in Tieszen’s phrase, but nevertheless an objective reality marked off “on the basis of what stabilizes or becomes invariant in our experience, on the basis of what has a history and a sedimentation that permits of further elaboration, development, constraints, surprises, and so on” (101). In something like this way, human reason and consciousness “constitute the meaning of being” of mathematical objects... (shrink)

Intentionality (‘directedness’, ‘aboutness’) is both a central topic in contemporary philosophy of mind, phenomenology and the cognitive sciences, and one of the themes with which both analytic and Continental philosophers have separately engaged starting from Brentano and Edmund Husserl’s ground-breaking Logical Investigations (1901) through Roderick M. Chisholm, Daniel C. Dennett’s The Intentional Stance, John Searle’s Intentionality, to the recent work of Tim Crane, Robert Brandom, Shaun Gallagher and Dan Zahavi, among many others. In this paper, I shall review recent discussions (...) of intentionality, including some recent explorations of the history of the concept (paying particular attention to Anselm), and suggest some ways the phenomenological approach of Husserl and Heidegger can still offer insights for contemporary philosophy of mind and consciousness.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 165 of the church regularly gives renewed expression to inspiration in constantly new existential contexts. There the Christian churches have sometimes done well, and sometimes less well, leading to disillusionment. We can regard all this as a generally accepted consensus among contemporary theologians, though the instruments of the church's teaching authority often have a tendency to dwell on ' the letter ' of earlier statements and to (...) underestimate their historieal and hermeneutical dimensions" (208). Those in the Magisterium who dwell on 'the letter ' believe, erroneously in Schillebeeckx's judgment, that history can and does give rise to nonnative, enduring facts and forms. Theologians who attend to historical relativizing and hermeneutical theorizing, correctly in Schillebeeckx's judgment, know better. His book is clearly designed to demonstrate this point. There is one sense in which his hook docs not, and indeed cannot, fail, given how the facts which he presents for the reader's judgment arise out of the theory with which he begins and necessarily point to the conclusion which his theory already presupposes. This is a fail-safe method for getting to where one wants to go. Unfortunately, it gets there by way of an enormous detour around the facticity of the Catholic faith and practice, a facticity which, despite the efforts of some of our best known (if not finest) theologians over a two thousand year history, has consistently refused to submit to the hypothetical and the theoretical reason of rationalist theologians. Our faith is centered on the Christ, the incarnate, historical Logos of tradition and Scripture, not on the disincarnate, unhistorical logos of theoretical theology. Schillebeeckx is not the first, nor will he be the last, theologian intent upon reducing the Catholic faith to some hypothetical methodology. Happily, however, and perhaps even miraculously, the Church always manages to survive her theologians, a fact which cannot but offer solace to many of the readers of this book.

McDoNOUGH. Albany: State University of New York Press, 1986. Pp. xii + 311. This book attempts an analysis of the Tractatits Logico-Philosophicus based on taking Wittgenstein's professed "fundamental idea' as the hermeneutic key. Tractatus 4.0312 states, in part: "My fundamental idea is 166 BOOK REVIEWS that the 'log·ical constants' are not representatives." McDonough believes that previous interpreters of the Tractatus have either ignored or downplayed the importance of this statement, and he writes in the conviction that taking it seriously produc&s a reading of the Tractatits that is friendlier toward philosophical language and argumentation than " the strong nagativ& views... which have been hastily claimed " as the import of the book (p. 11). In order to establish this "fundamental idea" as an interpretative device McDonough reminds the reader of links among three ideas. The first is the idea that the logical constants are not representatives. The second is the idea that the sole (real) logical constant is the general propositional form (T 5.47). The third is the fact that the status of the propositions of logic as tautologies exhibits the logic of their constituents, and hence, the logical properties of language and the world (T 6.12). By developing the relations among these ideas, and extending them to the interpretation of the Tractatiis as a whole, McDonough aims to show that Wittgenstein is committed to an explicit, only "technically nonsensical," philosophical doctrin& concerning the derivation of general metaphysical facts about ontology from general facts about the philosophy of logic. This doctrine he characterizes as "the argument of th& Tractatus." By attributing to the book an argmnent or doctrine (in the sense just mention &d) he contradicts those commentators who have understood Wittg·enstein to be earnestly requiring real silence about philosophy and to b& asserting seriously that the Tractatu,s is a self-refuting treatise, to be kicked aside. once its lessons are learned.

What does it mean to say that logic is formal? The short answer is: it means (or can mean) several different things. In this paper, I argue that there are (at least) eight main variations of the notion of the formal that are relevant for current discussions in philosophy and logic, and that they are structured in two main clusters, namely the formal as pertaining to forms, and the formal as pertaining to rules. To the first cluster belong (...) the formal as schematic; the formal as indifference to particulars; the formal as topic-neutrality; the formal as abstraction from intentional content; the formal as de-semantification. To the second cluster belong the formal as computable; the formal as pertaining to regulative rules; the formal as pertaining to constitutive rules. I analyze each of these eight variations, providing their historical background and raising related philosophical questions. The significance of this work of ?conceptual archeology? is that it may enhance clarity in debates where the notion of the formal plays a prominent role (such as debates where it is expected to play a demarcating role), but where it is oftentimes used equivocally and/or imprecisely.

In recent years, a significant amount of research has investigated the Vienna Circle’s ramifications. Otto Neurath has received much attention as one of the most prominent and energetic adherents, but less conspicuous philosophers now find themselves at the center of historical research. This article’s aim is to investigate Arne Naess’s connection to Logical Empiricism. Two crucial influences on Naess’s work are identified: Otto Neurath and the psychologist Egon Brunswik. This article’s most significant contributions are that, from the perspective of a (...) historian of philosophy of science, (a) Brunswik’s notion of “depth of intention” and his scientific methodological standards are reflected in Naess’s philosophy, (b) both Naess and Brunswik are adherents of Neurath’s physicalism, (c) Naess explicates Neurath’s notoriously vague concept of “congestions” in his “empirical semantics,” and (d) the latter is applied in Naess’s deep-ecology approach.

Well over a century after its introduction, Frege's two-dimensional Begriffsschrift notation is still considered mainly a curiosity that stands out more for its clumsiness than anything else. This paper focuses mainly on the propositional fragment of the Begriffsschrift, because it embodies the characteristic features that distinguish it from other expressively equivalent notations. In the first part, I argue for the perspicuity and readability of the Begriffsschrift by discussing several idiosyncrasies of the notation, which allow an easy conversion of logically equivalent (...) formulas, and presenting the notation's close connection to syntax trees. In the second part, Frege's considerations regarding the design principles underlying the Begriffsschrift are presented. Frege was quite explicit about these in his replies to early criticisms and unfavorable comparisons with Boole's notation for propositional logic. This discussion reveals that the Begriffsschrift is in fact a well thought-out and carefully crafted notation that intentionally exploits the possibilities afforded by the two-dimensional medium of writing like none other.

Even as concerns the present moment, the wor1d is such that I or you might not exist, and this contingency of cognitive beings, severally or generally, to the actual world, as a possibility inherent in it, may not without more ado be identified with the quite different possibility of another world, like to this e.x:cept for the absence of me or you. For the former is a real if passive possibility in a thing, viz., the world, the latter is merely an alternative conception or idea of a different and merely possible thing. The concept of my dog with a broken leg is a different concept from that of my dog as healthy, but it is of the same dog, and that is why I don't want him to break his 1eg. The world without me was and would be the same world, though differently conceived. This is the basic requirement of realism, which philosophers have often violated, confusing the metaphysical with the epistemological, the real with the certain. For example Descartes reasoned fallaciously from his being certain, as he thought, of the soul's but not of the body's existence to the ontological separateness of these two. Kant, again, seemed to reason from duty as a pure concept or epistemic entity to the real separwteness, as a positivie value, of the motive of duty from any motive of pleasure or aspiration to happiness. Yet it is possible, indeed probable, that in reality soul and body, a M. Devitt," Realism and the Renegade Putnam," Nous 1983, p. 297. MEANING IN A REALIST PERSPECTIVE 31 though distinguishable, do not have separate acts of existence,,and, in any human existence, that the motive of duty both cannot and ought not to be separated from the distinguishable...

Clark Butler has given us an English version of Hegel’s 1831 Lectures on Logic, the last course he was to complete before his death. The course was transcribed by his son Karl and first published in 2001 . Although the manuscript is not Hegel’s own, its contents are unmistakably authentic, opening an interesting window on Hegel’s thinking while he was preparing a second edition of the Logic. Readers familiar with that work will find that the content of the (...) lectures conforms to the standard version. But the real interest of these lectures lies in Hegel’s freer discussion of the logical categories, in the course of which he frequently gives illustrations from ethics and history.Butler’s interest in the lectures is in keeping with Hegel’s intention to reach a wider audience ; accordingly, Butler has introduced numerous interpolations in order to “produce a readable text for those who are not Hegel scholars” and to “make the science of logic not only readable but teachable” . It may be questioned, however, to what extent Butler has succeeded. One difficulty stems from his intention to heed “Hegel’s professed true intent” , even where this brings him into conflict with the letter of the text. Noting that Hegel’s “panlogicist. (shrink)

This paper intends to explain key differences between Aristotle’s understanding of the relationships between nous, epistêmê, and the art of syllogistic reasoning(both analytic and dialectical) and the corresponding modern conceptions of intuition, knowledge, and reason. By uncovering paradoxa that Aristotle’s understanding of syllogistic reasoning presents in relation to modern philosophical conceptions of logic and science, I highlight problems of a shift in modern philosophy—a shift that occurs most dramatically in the seventeenth century—toward a project of construction, a pervasive desire (...) for rational certainty, and a general insistence on the reducibility of the sciences. The major motivation of this analysis is my intention to show that modern attempts to reduce science/epistêmê to a single science/method of inquiry occlude dialectical and ethico-political dimensions of “reason” and, hence, also impoverish philosophy’s critical capacities.

This collection of prize-winning essays addresses the controversial question of how meaning and goals can emerge in a physical world governed by mathematical laws. What are the prerequisites for a system to have goals? What makes a physical process into a signal? Does eliminating the homunculus solve the problem? The three first-prize winners, Larissa Albantakis, Carlo Rovelli and Jochen Szangolies tackle exactly these challenges, while many other aspects feature in the other award winning contributions. All contributions are accessible to non-specialists. (...) These seventeen stimulating and often entertaining essays are enhanced versions of the prize-winning entries to the FQXi essay competition in 2017.The Foundational Questions Institute, FQXi, catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlikely to be supported by conventional funding sources.
