ABSTRACT Wilfrid Sellars argued that Kant’s account of the conceptual structures involved in experience can be given a linguistic turn so as to provide an analytic account of the resources a language must have in order to be the bearer of empirical knowledge. In this paper I examine the methodological aspects of Kant’s transcendental philosophy that Sellars took to be fundamental to influential themes in his own philosophy. My first aim here is to clarify and argue for the plausibility (...) of what I claim is Sellars’ interpretation of Kant’s ‘analytic’ transcendental method in the first Critique, based ultimately on non-trivial analytic truths concerning the concept of an object of our possible experience. Kant’s ‘transcendental proofs’ thereby avoid a certain methodological trilemma confronting the candidate premises of any such proof, taken from Sellars’ 1970s undergraduate exam question on Kant. In part II of the essay I conclude by highlighting in general terms how Kant’s method, as interpreted in the analytic manner explained in part I, was adapted by Sellars to produce some of the more influential aspects of his own philosophy, expressed in terms of what he contends is their sustainable reformulation in light of the so-called linguistic turn in twentieth-century philosophy.

Wittgenstein’s use of the word ‘phenomenology’ to describe his own work in Philosophical Remarks and The Big Typescript has occasioned much puzzlement and confusion. This paper seeks to shed light on what Wittgenstein meant by the word through a close analysis of key passages in those two works. I argue against both the view of Nicholas Gier that Wittgenstein held ‘grammatical’ phenomenological remarks to be synthetic a priori and that expressed by Moritz Schlick that Wittgenstein held grammar to be (...) tautological. I also take issue with the claim by Merrill and Jaakko Hintikka that Tractatus Logico-Philosophicus ought to be regarded as a work of phenomenology. Wittgenstein’s adoption of a variant of Husserlian phenomenology, I argue, lasted no more than a few months, from February to October 1929, during which he conceived of phenomenology as something that sought to establish what one might call ‘analytic a posteriori’ truths through something like the Husserlian method of ‘bracketing’. By the end of 1929, I claim, he had abandoned that in favour of the view expressed in the slogan ‘phenomenology is grammar’, where ‘grammar’ is not confined to the tautological, but is rather intimately linked to Wittgenstein’s notion of ‘the understanding that consists in seeing connections’.

The terms "a priori" and "a posteriori" refer primarily to how or on what basis a proposition might be known. A proposition is knowable a priori if it is knowable independently of experience. A proposition is knowable a posteriori if it is knowable on the basis of experience. The a priori/a posteriori distinction is epistemological and should not be confused with the metaphysical distinction between the necessary and the contingent or the semantical or logical (...) distinction between the analytic and the synthetic. Two aspects of the a priori/a posteriori distinction require clarification: the conception of experience on which the distinction turns; and the sense in which a priori knowledge is independent of such experience. The latter gives rise to important questions regarding the positive basis of a priori knowledge. (shrink)

The viewpoint of Evolutionary Epistemology (EE) and of Genetic Epistemology (GE) on classical epistemological questions is strikingly different: EE starts with Evolutionary Biology, the subject of which is population's dynamics. GE, however, starts with Developmental Psychology and thus focusses the development of individuals. By EE knowledge is seen as portraying or copying process, and truth is interpreted as a product of adaptation, whereas for GE knowledge is due to a construction process in which the production of true insights is (...) only one possibility among others: Like falsity, error and deception, true knowledge goes back to a free relationship to reality. The difference between scientific and common knowledge is hard to be checked by EE, since both result ultimately from human hereditary structures. The study of how scientific knowledge emerges from everyday cognition is rather the task of GE. (shrink)

This collection focuses on the ontology of space and time. It is centred on the idea that the issues typically encountered in this area must be tackled from a multifarious perspective, paying attention to both a priori and a posteriori considerations. Several experts in this area contribute to this volume: G. Landini discusses how Russell’s conception of time features in his general philosophical perspective;D. Dieks proposes a middle course between substantivalist and relationist accounts of space-time;P. Graziani argues that (...) it is necessary to provide an account of the “synthetic procedures” implicit in the recourse to diagrams in Euclid’s Elements, while E. Mares comes to the conclusion that in Euclid’s Elements we should treat the parallel postulate as empirical and the postulate that space is continuous as a priori. M. Arsenijevi?/M. Adži? present an important formal result concerning two theories of the infinite two-dimensional continua, which sheds new light on the current dispute between gunkologists and pointilists; F. Orilia discusses two problems for presentism, one regarding the duration of the present and the other related to Zeno’s paradoxes. A. Iacona delves deep into logical matters by focusing on the so-called T×W modal frames in order to deal with the deteterminism-indeterminism controversy. D. Mancuso outlines a non-standard temporal model compatible with time travel, andV. Fano/G. Macchia discuss time travels in the light of an important foundational principle of modern cosmology, Weyl’s Principle. (shrink)

This paper will make the case that we can find in Kant’s Second Analogy a substantive response to Hume’s argument on induction. This response is substantive insofar as it does not merely consist in independently arguing for the opposite conclusion, but rather, it identifies and exploits a gap in this argument. More specifically, Hume misses the possibility of justifying the uniformity of nature as a synthetic a priori proposition, which Kant looks to establish in the Second Analogy. Note that (...) the focus on the paper is on Kant’s identification of the form that a solution to Hume’s inductive scepticism must take. In making this point, my paper will look to establish two lemmas: Kant identifies synthetic a priori judgments as a means of justifying metaphysical knowledge in a way that circumvents Hume’s dichotomy between matters of fact and relations of ideas; the Second Analogy looks to establish the uniformity of nature of as a synthetic a priori proposition. However, my paper generally abstains from the question of the tenability of Kant’s argument in the Second Analogy. Doing justice to this latter discussion would require more space than I am able to offer here. My paper therefore has a conditional bearing on the philosophical issue of inductive scepticism. If one believes Kant’s Second Analogy to be philosophically cogent, then Kant offers a successful justification of induction against Hume’s scepticism. If not, then at least one can still admire Kant’s identification of the gap in Hume’s argument, which, to a degree, can be exploited independently of Kant’s system. (shrink)

This paper attempts to shed light on three sets of issues that bear directly on our understanding of Locke and Kant. The first is whether Kant believes Locke merely anticipates his distinction between analytic and synthetic judgments or also believes Locke anticipates his notion of synthetic a priori cognition. The second is what should we as readers of Kant and Locke should think about Kant’s view whatever it turns out to be, and the third is the nature of (...) Kant’s justification for the comparison he draws between his philosophy and Locke’s. I argue (1) that Kant believes Locke anticipates both the analytic-synthetic distinction and Kant’s notion of synthetic a priori cognition, (2) that the best justification for Kant’s claim draws on Locke’s distinction between trifling and instructive knowledge, (3) that the arguments against this claim developed by Carson, Allison, and Newman fail to undermine it, and (4) that Kant’s own justification for his claim is quite different from what many commentators have thought it was (or should have been).

In his essay “Logical Empiricism”, in the anthology Twentieth Century Philosophy, Professor Feigl writes: “All forms of empiricism agree in repudiating the existence of synthetic a priori knowledge.” Schlick makes the same point even more forcibly: “The empiricism which I represent believes itself to be clear on the point that, as a matter of principle, all propositions are either synthetic a posteriori or tautologous; synthetic a priori propositions seem to it to be a logical impossibility.” The denial (...) of synthetic a prioris is a major thesis of the logical empiricist position, being found in the writings of most of the leaders of the movement. The reason for its importance is fairly clear. It provides a formula on which the empiricists can base their critique of traditional philosophy. To use Ayer's phrase, denial of the synthetic a priori results in “the elimination of metaphysics”. The philosophical tradition to which the empiricists are opposed and whose “metaphysics” they wish to eliminate can be called, somewhat loosely, rationalism. (shrink)

The paper aims at analyzing Lambert’s conception of empirical knowledge that is part of scientific learning. Indeed, in the Neues Organon, he claims that science is obtained with the help of both a priori and a posteriori knowledge. Lambert’s originality lies on the application of the analytic and synthetic methods of reasoning, which are traditionally used in formal disciplines, to the realm of experience. Transforming common knowledge into scientific a posteriori knowledge is mainly based on the (...) employment of such demonstrative methods. This allows Lambert to introduce some important theoretical tools in his theory of experience, in particular about the search for the conditions of observations and experimentations as well as the establishment of hypothesis. For Lambert, the synthetic method in empirical deductions requires the use of conjectures and probable principles. (shrink)

In this chapter I consider three different positions on the a priori/a posteriori distinction that have been attributed to Hegel, specifically in the context of the epistemology of the metaphysical claims he defends in his Realphilosophie. I outline and briefly provide evidence for a reading of Hegel that understands him to retain the distinction in question, but to hold that the metaphysical claims he defends in the context of his philosophy of nature and his philosophy of spirit typically (...) involve elements of both a priori and a posteriori knowledge. I then defend this interpretation against two competitors. The first of these also takes Hegel to retain the distinction, but holds that the conclusions of his Realphilosophie, like those of his logic, are principally to be understood as known a priori. The second takes Hegel to abandon the a priori/a posteriori distinction altogether. I argue that these alternatives are less compelling. (shrink)

This essay criticizes Williamson’s attempt, in his book, The Philosophy of Philosophy, to undermine the interest of the a priori–a posteriori distinction. Williamson’s argument turns on several large claims. The first is that experience often plays a role intermediate between evidential and merely enabling, and that this poses a difficulty for giving a theoretically satisfying account of the distinction. The second is that there are no constitutive understanding–assent links. Both of these claims are subjected to detailed scrutiny. In (...) particular, it is argued that Williamson’s case of the deviant logician, Simon, fails to constitute an intelligible counterexample to the status of conjunction elimination as an understanding–assent link for ‘and’.

In twentieth-century Kant scholarship, few have provided an account of the analytic-synthetic distinction and of the problem of the synthetic a priori that takes into consideration the views of Kant's idealist successors such as Maimon, Fichte, Schelling, and Hegel. I first explain how Kant formulates the analytic-synthetic distinction in terms of the determinate-indeterminate distinction, which, in turn, is based on the distinction between general and transcendental logic. Kant's problem of the synthetic a priori , then, is (...) the problem of showing how the logical forms of judgment can be employed determinately (and not merely indeterminately). I then show that Maimon also formulates the distinction and the problem in the same way, and that his interpretation will shape how Fichte, Schelling, and Hegel each construe and address Kant's question, How are synthetic judgments possible a priori ?

This article focuses on the distinction between analytic truths and synthetic truths, and between a priori truths and a posteriori truths in philosophy, beginning with a brief historical survey of work on the two distinctions, their relationship to each other, and to the necessary/contingent distinction. Four important stops in the history are considered: two involving Kant and W. V. O. Quine, and two relating to logical positivism and semantic externalism. The article then examines questions that have been (...) raised about the analytic–synthetic and a priori–a posteriori distinctions, such as whether all distinctively philosophical truths fall on one side of the line and whether the distinction is relevant to philosophy. It also discusses the argument that there is a lot more a priori knowledge than we ever thought, and concludes by describing epistemological accounts of analyticity. (shrink)

Fodor and LePore's attack on conceptual role semantics relies on Quine's attack on the traditional analytic/synthetic and a priori/a posteriori distinctions, which in turn consists of four arguments: an attack on truth by convention; an appeal to revisability; a claim of confirmation holism; and a charge of explanatory vacuity. Once the different merits of these arguments are sorted out, their proper target can be seen to be not the Traditional Distinctions, but an implicit assumption about their superficial (...) availability that we have abundant reason to reject. Once we reject it, we can see how issues of the absorbtion of conventions, the revisability of belief, and confirmation holism are compatible with the Traditional Distinctions, and that Quine's discussion only serves to camouflage the question of whether some confirmation relations are constitutive of meaning and knowable a priori.

Kant influentially distinguished analytic from synthetic a priori propositions, and he took certain propositions in the latter category to be of immense philosophical importance. His distinction between the analytic and the synthetic has been accepted by many and attacked by others; but despite its importance, a number of discussions of it since at least W. V. Quine’s have paid insufficient attention to some of the passages in which Kant draws the distinction. This paper seeks to clarify what (...) appear to be three distinct conceptions of the analytic (and implicitly of the synthetic) that are presented in Kant’s Critique of Pure Reason and in some other Kantian texts. The conceptions are important in themselves, and their differences are significant even if they are extensionally equivalent. The paper is also aimed at showing how the proposed understanding of these conceptions—and especially the one that has received insufficient attention from philosophers—may bear on how we should conceive the synthetic a priori, in and beyond Kant’s own writings.

This is the second in a two part series of articles that attempt to clarify the nature and enduring relevance of Kant's concept of a priori knowledge. (For Part I, see below.) In this article I focus mainly on Saul Kripke's critique of Kant, in Naming and Necessity. I argue that Kripke draws attention to a genuine defect in Kant's epistemological framework, but that he used definitions of certain key terms that were quite different from Kant's definitions. When Kripke's (...) definitions are replaced by Kant's definitions, Kripke's account of the status of naming turns out to be a defense of analytic aposteriority as a significant classification of knowledge that Kant neglected. I also introduce here a new way of understanding such epistemological labels, as defining the perspective adopted by the knowing subject in a given situation, rather than an objective characteristic of certain propositions as such.

This work sets out to perform a psychoanalytic inversion of transcendental philosophy, taking Kant's synthetic a priori judgments and reading them in terms of a foreclosed Kantian category, that of the analytic a posteriori.

Under the influence of Leibnitz in oposition to Kant, especially against his philosophy of mathematics, Bolzano analyses several topics discussed in analytic philosophy of today. His starting point is a distinction of concepts and intuitions, being two basic kinds of ideas-in-themselves, based on the postulates of nonemptiness, singularity and simplicity. This dichotomy is utilized in the analysis of conceptual and empirical sentences , the analytic/synthetic distinction and the a priori and a posteriori differentiation. His classification of (...) analytic sentences, based on his logic of variation and the degree of validity, in a narrow and broader sense corresponds to the contemporary view of analyticity for logical and linguistic reasons. Inspite of his ontological atomism he anticipates Quine´s holism according to which empirical sciences are theory-laden. He even accepts, at least for historical reasons, his empiricism concerning the role of observation sentences in theoretical sciences. According to Bolzano, no sharp demarcation between conceptual and empirical sciences can be drawn. (shrink)

ABSTRACT: It is a familiar story that Kant’s defence of our synthetic a priori cognition in the Critique of Pure Reason suffered sharp criticism throughout the extended philosophical revolutions that established analytic philosophy, the pragmatist tradition, and the phenomenological tradition as dominant philosophical movements in the first half of the twentieth century. One of the most important positive adaptations of Kant’s outlook, however, was the combined analytic and pragmatist conceptions of the a priori that were developed (...) by the American philosophers C. I. Lewis (1883–1964) and Wilfrid Sellars (1912–1989), most notably in Lewis’s 1929 classic, Mind and the World Order, followed by Sellars’ critical reworking of Lewis’s outlook in ‘Is There a Synthetic A Priori?’ (1953) and other mid-century articles. Both Lewis and Sellars defended central aspects of Kant’s analysis of our a priori knowledge of mind-independent physical objects and necessary causal connections. But both also radically transformed Kant’s view by defending the idea that there are alternative a priori conceptual frameworks that are subject to an ongoing process of reassessment and replacement on overall pragmatic and explanatory grounds. Furthermore, while Sellars’ answer to his question, ‘Is There a Synthetic A Priori?’ thus represented a partial endorsement of Lewis’s pragmatic relativization of the a priori, I argue that Sellars’ account of meaning diverged from Lewis in ways that constituted a significant improvement upon the previous ‘analytic’ defenses of the a priori, not only in Lewis but in general. This arguably has implications for wider disputes concerning the nature and possibility of a priori knowledge in non-formal domains. (shrink)

Lauener's philosophical approach is well-articulated and has many features that are fully justified: epistemology appears at the level of metascience, as a normative discipline; Lauener's transcendentalism is open, the norms being able to evolve over time; in his analytic a priori-synthetic a posteriori dichotomy, analyticity is relative to the context and results from conventions, and the dichotomy is compatible with Quine's universal revisibility; Lauener has shown that a theory and the metatheory it is based on cannot be (...) revised at the same time, a strong argument for ontological relativity but against general holism, he conceives of tmth as applicable only within a theory, relative to an ontology and dependent on references, etc. Other aspects, however, appear more problematic: the idea that mathematical entities are the product of our thinking, which makes them more similar to fictional than to physical objects (the main objection to this is that mathematics plays a constitutive role in physical concepts), or the tendency to speak of "existence relative to modem physics" (as if real existence were a type of existence, on a par with existence in fiction).

I argue for the claim that there are instances of a priori justified belief – in particular, justified belief in moral principles – that are not analytic, i.e., that cannot be explained solely by the understanding we have of their propositions. §1–2 provides the background necessary for understanding this claim: in particular, it distinguishes between two ways a proposition can be analytic, Basis and Constitutive, and provides the general form of a moral principle. §§3–5 consider whether Hume's (...) Law, properly interpreted, can be established by Moore's Open Question Argument, and concludes that it cannot: while Moore's argument – appropriately modified – is effective against the idea that moral judgments are either reductively analyzable or Constitutive-analytic, a different argument is needed to show that they are not Basis-analytic. Such an argument is supplied in §6. §§7–8 conclude by considering how these considerations bear on recent discussions of “alternative normative concepts”, on the epistemology of intuitions, and on the differences between disagreement in moral domains and in other a priori domains such as logic and mathematics.

I present and defend a unified, non-reductive analysis of the a priori and a posteriori. It is a mistake to remove all epistemic conditions from the analysis of the a priori (as, for example, Alvin Goldman has recently suggested doing). We can keep epistemic conditions (like unrevisability) in the analysis as long as we insist that a priori and a posteriori justification admit of degrees. I recommend making the degree to which a belief’s justification is (...) a priori or a posteriori solely dependent on the revisability relations that obtain among the faculties that deliver the belief and all other faculties.

In a 1793 essay, J. Ch. Schwab claimed that Kant's distinction between analytic and synthetic judgments was already known to the Megarian philosopher Stilpo. Schwab's essay was criticised as early as 1794 by J. F. Ch. Gräffe. In a 1789 essay, J. A. Eberhard had also denied the originality of Kant's division of judgments and made certain indications suggesting that Aristotle was aware of the distinction. In this paper, I propose a fresh examination of why Schwab is wrong to (...) attribute knowledge of Kant's division of judgments to Stilpo – a second look which, however, does not disregard Gräffe's contributions to the discussion. Second, I argue that, in a precise sense, Kant's division of judgments is indeed original, but that the analytic – synthetic distinction was nevertheless in a sense known to Aristotle. The assessment of these alleged precedents sheds light no only on the novelty of Kant's philosophical project but also on what may be called the "the paradox of the discovery of an evident philosophical distinction".

Many philosophers take the distinguishing mark of their subject to be its a priori status. In their view, where empirical science is based on the data of experience, philosophy is founded on a priori intuitions. In this paper I shall argue that there is no good sense in which philosophical knowledge is informed by a priori intuitions. Philosophical results have just the same a posteriori status as scientific theories. My strategy will be to pose a familiar (...) dilemma for the friends of a priori philosophical intuitions. I shall ask them whether their intuitions are supposed to be analytic or synthetic. And then I shall argue that, if the intuitions are analytic, they may be a priori, but will be philosophically uninteresting; while, if they are synthetic, they may be philosophically interesting, but will not merit being treated as a priori in the context of philosophical debate. At the end of the paper I explain that this does not mean that philosophy should abandon ‘armchair’ methods. We still need to uncover and examine the often unrecognized intuitions that drive our thinking. However this is not because they provide a distinctive source of a priori knowledge, but on the contrary because they may be leading us astray. (shrink)

According to Kant in the Prolegomena, the natural kind proposition (GYM) "Gold is a yellow metal" is analytically true, necessary, and a priori. Saul Kripke and Hilary Putnam have argued that on the contrary propositions such as (GYM) are neither analytic, nor necessary, nor a priori. The Kripke-Putnam view is based on the doctrine of "scientific essentialism" (SE). It is a direct consequence of SE that propositions such as (GE) "Gold is the element with atomic number number (...) 79" are metaphysically necessary and a posteriori. Were Kant to travel by time-machine to the present and to consider (GE), however, he would regard it as metaphysically contingent; and even if he were able to admit it as necessary, it would be synthetic a priori, and not a posteriori. In these ways, the conflict between Kant and the scientific essentialists is a sharply-defined one: if the essentialists are right, then the Kantian theory of meaning, necessity, and a priori knowledge is wrong; but if Kant is right, then SE is wrong. As a prolegomenon to the development and defense of Kant's positive theory of natural kind propositions, this paper undertakes a Kantian critique of SE. Following the Introduction, the paper has three sections. The first section spells out the main theses and assumptions of SE. The second section, setting aside the semantic and logical components of SE, focuses on its epistemic and metaphysical components and offers four Kantian arguments against them. The final section offers Kantian "diagnoses" of the flaws in SE exposed by the four critical arguments. (shrink)

We argue that in spite of their apparent dissimilarity, the methodologies employed in the a priori and a posteriori assessment of probabilities can both be justified by appeal to a single principle of inductive reasoning, viz., the principle of symmetry. The difference between these two methodologies consists in the way in which information about the single-trial probabilities in a repeatable chance process is extracted from the constraints imposed by this principle. In the case of a posteriori reasoning, (...) these constraints inform the analysis by fixing an a posteriori determinant of the probabilities, whereas, in the case of a priori reasoning, they imply certain claims which then serve as the basis for subsequent probabilistic deductions. In a given context of inquiry, the particular form which a priori or a posteriori reason may take depends, in large part, on the strength of the underlying symmetry assumed: the stronger the symmetry, the more information can be acquired a priori and the less information about the long-run behavior of the process is needed for an a posteriori assessment of the probabilities. In the context of this framework, frequency-based reasoning emerges as a limiting case of a posteriori reasoning, and reasoning about simple games of chance, as a limiting case of a priori reasoning. Between these two extremes, both a priori and a posteriori reasoning can take a variety of intermediate forms. (shrink)

This paper offers an account of the a priori/a posteriori distinction utilizing the insights of reliabilism, focusing on the inputs to reliable belief-forming processes. Ipropose that a belief possesses a priori justification if it is the result of a reliable belief-producing process whose input is ‘non-sensory’ and the reliability of this process does not ‘causally depend’ on the reliability of a prior process taking in ‘sensory’ input. One of the interesting consequences of this account is in the (...) treatment of introspective knowledge of one’s belief-states; it was classically considered a posteriori, but comes out a priori on this model.

Kant’s analytic-synthetic distinction is often construed in terms of the question of whether or not the predicate is contained in or can be derived from the concept of the subject. Few have observed that Kant has another formulation of the distinction, a formulation that is based on the determinate-indeterminate distinction. In fact, it is this formulation that will shape the development of one of the main tasks of post-Kantian German idealism. It is my aim to explain how Kant, Maimon, (...) and Fichte each define and address the problem of the synthetic a priori in terms of the determinate-indeterminate distinction. (shrink)

John Dewey and Bertrand Russell visited China at around the same time in 1920. Both profoundly influenced China during the great transition period of this country. This article will focus on the differences between the two great figures that influenced China in the 1920s. This comparison will examine the following five aspects: 1. Deweyanization vs. Russellization; 2. Dewey’s “Populism” vs. Russell’s “Aristocraticism”; 3. Dewey’s “Syntheticalism” vs. Russell’s “Analyticalism”; 4. Dewey’s “Realism” vs. Russell’s “Romanticism”; 5. Dewey’s “Conservatism” vs. Russell’s “Radicalism”. This (...) examination will highlight that, although their visit left indelible impressions among Chinese intellecturals, for the radical Marx–Leninists, any Western philosophy and socio-political theories, including Dewey’s and Russell’s, were prejudicial, outworn, and even counterrevolutionary. Soon “Marxi–Leninization” was gradually substituted for “Deweyanization” and “Russellization.”. (shrink)

The analytic/synthetic distinction has played a central role in discussions of a priori knowledge throughout the twentieth century. One of the primary reasons for the prominence of this distinction is the widespread influence of the tradition of logical empiricism which endorsed the following principles: All analytic propositions are knowable a prioriand All propositions knowable a priori are analytic.Hence, proponents of the a priori often argue in support of the contention that the propositions of a (...) particular discipline, say mathematics or logic, are knowable a priori by arguing that it consists solely of analytic propositions. On the other hand, detractors of the a priori often reject such knowledge on the grounds that the analytic/synthetic distinction is not cogent. My primary goal in this paper is to challenge the prevalent acceptance of. (shrink)

In the vast majority of the literature on Kant, the prevailing view is that his conception of analyticity and analytic truths suffers from obscurities and inconsistencies that render it, in the end, unintelligible. In the present paper, I try (i) to underline the meaning of these conceptions of Kant’s, (ii) to bring to the fore a crucial hidden presupposition in his account of analytic truths, and (iii) to present an interpretation that restores an intelligible account of Kantian analyticity (...) and analytic truth. Contrary to the ‘received’ view, I claim that definition is the royal way to Kant’s analyticity and analytic truth, and that the latter cannot be understood apart from a very specific kind of appeal to the intuition of the object falling under the concept being defined. I call this elusive and fragile act “simple intuition,” pointing thus to the medieval notion of apprehensio simplex (and the long history behind it). Then I try to show how this is done with reference to the most suitable species of concepts, the mathematical, and by analogy (and with expectable limitations) to the empirical ones. Of course, the present attempt to reconstruct an intelligible Kantian account of analyticity and analytic truths does not also mean that I endorse it as successful and final in the context of philosophy’s effort to clarify the possibility and kinds of a priori truths.

The article consists of a brief biographical account of Immanuel Kant’s life and career, followed by a discussion of his basic philosophy, and a brief discussion of his pivotal point in the history of Rhetoric and Communicology. A major figure in the European Enlightenment period of Philosophy, his Collected Writings were first published in 1900 constituting 29 volumes. He wrote three major works that are foundational to the development of Western philosophy and the human sciences. Often just referred to as (...) the “Three Critiques” informally, the First, the Second, and the Third. These are respectively: The Critique of Pure Reason focused on issues in logic, The Critique of Practical Reason relating ethical guidelines, and The Critique of Judgment exploring issues of aesthetics. He is most famous for his philosophy of transcendental idealism. This version of idealism argues that in logic statements are analytic or synthetic. He further argues that statements are a priori or a posteriori. Models of rhetoric, phenomenological methodology, and the contemporary Perspectives Model of interpersonal communicology are included as the Kantian legacy in the US. Notes provide a guide to edition and philological issues in the Kantian corpus, especially for the hermeneutics of Vorstellung versus Darstellung. (shrink)

I argue that there are analytic claims that, if true, can be known a priori, but which also can turn out to be false: they are expressive of merely default instructions from the language faculty to the conceptual system, which may be overridden by pragmatic or scientific considerations, in which case, of course, they would not be known at all, a priori or otherwise. More surprisingly, I also argue that they might not be, strictly speaking, conceptual: concepts (...) may be importantly different from the meaning instructions for the words we use to express them. I will press all this in the context of a general Quinean “naturalism,” where the epistemology that interests me is “a chapter of natural science,” but where the science won't be Quine's behaviorism, but a Chomskyan theory of the “I-semantics” of “I-language.” But, relying on a distinction I draw between an explanatory and a working epistemology, I will be pressing it largely as an explanatory claim, not one that will have serious consequences for on-going philosophical practice, neither with regard to the world, nor, more surprisingly, even with regard to armchair “conceptual analysis.” As Putnam observed, there may be analytic truths, but they don't cut much philosophical ice.

The paper outlines an interpretation of one of the most important and original contributions of David Hilbert’s monograph Foundations of Geometry , namely his internal arithmetization of geometry. It is claimed that Hilbert’s profound interest in the problem of the introduction of numbers into geometry responded to certain epistemological aims and methodological concerns that were fundamental to his early axiomatic investigations into the foundations of elementary geometry. In particular, it is shown that a central concern that motivated Hilbert’s axiomatic investigations (...) from very early on was the aim of providing an independent basis for geometry. Accordingly, these concerns about an independent grounding for elementary geometry determined very clear methodological constraints in the process of embedding it into a formal axiomatic system. It is argued that Hilbert not only sought to show that geometry could be considered a pure mathematical theory, once it was presented as a formal axiomatic system; he also aimed at showing that in the construction of such an axiomatic system one could proceed purely geometrically, avoiding concept formations borrowed from other mathematical disciplines like arithmetic or analysis.

Does Carnap’s treatment of philosophical questions about existence, such as “Are there numbers?” and “Are there physical objects?”, depend on his analytic–synthetic distinction? If so, in what way? I answer these questions by clarifying, defending, and developing the reading of Carnap’s paper “Empiricism, Semantics, and Ontology” that W. V. Quine proposes, with little justification or explanation, in his paper “On Carnap’s Views on Ontology”. The primary methodological value of studying Quine’s reading of “Empiricism, Semantics, and Ontology” is that it (...) prompts us to look for, and helps us to see the significance of, passages by Carnap that reveal the logical foundations of his views on ontology. Guided in this way by Quine’s reading, I show that (1) in “Empiricism, Semantics, and Ontology” Carnap’s preferred treatment of philosophical questions relies on paraphrasing them so that their answers are immediately obvious elementary logical truths, and are therefore, by his standards, trivially analytic; and (2) in its most general form, Carnap’s treatment of philosophical questions about existence depends on his controversial view that the analytic truths of a language L may include sentences that are not elementary logical truths, but that are nevertheless, by Carnap’s standards, analytic-in-L simply because we have stipulated that they are to be among the “meaning postulates” of L.

I draw attention to a 12-page Vorarbeit to Kant’s Prolegomena from the so-called Scheffner-Nachlaß and argue that the parallel Kant draws there between the possibility of theoretical and practical synthetic a priori propositions provides important insight into the development of his account of practical autonomy in the Groundwork. Based on a brief sketch of the role synthetic a priori propositions play in the development of Kant’s critical philosophy, I conclude that for Kant the objective validity of any science (...) depends on the objective validity of a number of synthetic a priori propositions.

The problem of synthetic judgements touches on the question of whether philosophy can draw independent statements about reality in the first place. For Kant, the synthetic judgements a priori formulate the conditions of the possibility for objectively valid knowledge. Despite the principle fallibility of its statements, modern science aims for objective knowledge. This gives the topic of synthetic a priori unbroken currency. This paper aims to show that a modernized version of transcendental philosophy, if it is to be (...) feasible at all, must “bid farewell” to the concept of being “free of empiricism” or the “purity” of the a priori. Approaches to this end can already been found in Kant’s reflections on non-pure synthetic knowledge. Moreover, the a priori validity of knowledge does not exclude the possibility that it can be discovered empirically. In keeping with Kant, Fries and Nelson anticipated this separation (usually first attributed to Reichenbach) between the validity and discovery context of knowledge and pointed out that the a priori could be discovered empirically, but never proven. There are currently still good reasons why transcendental philosophical concepts are of fundamental importance for modern science, although it must not be overlooked that even within the framework of a modernized transcendental philosophy, several unsolved problems remain or are raised. For example, the irredeemability of the universal validity and necessary claims of the a priori, the problem of a clear demarcation between the phenomenal and noumenal world. Moreover, the “beautiful structure” or the Kantian system, which constituted its persuasive power, is lost. (shrink)

This essay reassesses the relation between Kant and Kripke on the relation between necessity and the a priori. Kripke famously argues against what he takes to be the traditional view that a statement is necessary only if it is a priori, where, very roughly, what it means for a statement to be necessary is that it is true and could not have been false and what it means for a statement to be a priori is that it (...) is knowable independently of experience. Call such a view the Entailment Thesis. Along with many Kant scholars, Kripke thinks that Kant endorses the Entailment Thesis. Thus Kripke and many others take his arguments against the Entailment Thesis to tell against Kant and to mark an important point of disagreement with him. I will argue that this is a mistake. Kant does not endorse the Entailment Thesis that Kripke and many others attribute to him. He does endorse two quite different theses concerning the relation between necessity and the a priori, as he conceives them. One is a matter of definition and the other is a very substantial philosophical thesis indeed—to establish it is the aim of the entire Critique of Pure Reason. But Kripke’s arguments against the Entailment Thesis tell against neither of Kant’s theses, as they involve crucially different conceptions of necessity and the a priori. This superficial lack of disagreement masks deep disagreements, but these result from divergent views regarding matters such as realism, modal epistemology, and philosophical methodology; views which Kant does a lot, and Kripke very little, to argue for.

Kant informs us that the categorical imperative is a synthetic a priori proposition. It might be thought that Kant means thereby to say that we have an a priori rational insight, somewhat like that which Plato claimed for the Forms, into this basic moral truth. W. D. Ross had a similar view about human rational insight into certain basic moral principles, and in his book Kant's Ethical Theory he attritubes such a view to Kant.I argue that this initially (...) plausible interpretation is not correct, and that the "rational intuitionism" that it involves goes against Kant's whole approach to philosophy, in the first Critique as well as in the moral philosophy. I develop a new alternative interpretation, as follows: the categorical imperative is synthetic because it contains a claim about the causal/motivational power we have to act purely from the motive of duty, without any assistance from "sensible" or empirical motives, such as pleasure or pain. This claim, qua motivational, goes beyond the meaning of the categorical imperative considered as a mere ethical precept. It is a priori because this motive's source is the noumenal self.Hence to justify the categorical imperative is to show that this sort of non-sensible motive is or could be active in us as agents, and Kant is an "internalist": one who believes that morality and motivation are internally, analytically connected. Nach Kant ist der kategorische Imperativ ein synthetischer Satz a priori. Kant könnte damit sagen wollen, wir hätten in die grundlegende moralische Wahrheit, die der kategorische Imperativ darstellt, eine vernünftige Einsicht a priori, die unserer Wahrnehmung der Formen, wie Plato sie sieht, vergleichbar wäre. W. D. Ross vertrat eine ähnliche Auffassung von einer vernünftigen menschlichen Einsicht in gewisse grundlegende moralische Prinzipien, und in seinem Buch "Kant's Ethical Theory" schreibt er diese Auffassung auch Kant zu.Ich behaupte, daß diese auf den ersten Blick als plausibel erscheinende Interpretation nicht richtig ist, und daß der "rationale Intuitionismus", den sie impliziert, Kants philosophischem Ansatz, sowohl in der ersten Kritik als auch in der Moralphilosophie, ganz grundsätzlich widerspricht. Ich entwickele eine neue, alternative Interpretation: Der kategorische Imperativ ist synthetisch, weil er eine Behauptung über eine kausale/motivationale Kraft enthält, die uns zukommt und die uns befähigt, ohne irgendeine Unterstützung durch bloß empirische oder Beweggründe der Zweckrationalität wie Freude oder Schmerz allein aus der Vorstellung der Pflicht heraus zu handeln. Soweit sie den vernünftigen Beweggrund zu handeln betrifft, geht die Behauptung über die Bedeutung des kategorischen Imperativs als eines rein ethischen Gebots hinaus. Sie ist a priori, da die Quelle des vernünftigen Beweggrunds das noumenale Ich ist.Jede Rechtfertigung des kategorischen Imperativs muß folglich zeigen, daß die fragliche Art vernünftiger Beweggründe, die nicht Beweggründe bloßer Zweckrationalität sind, in uns als Handelnden aktiv ist oder jedenfalls aktiv sein könnte und daß Kant insoweit ein "Internalist" ist: das ist jemand, der meint, Moral und Motivation seien innerlich, analytisch miteinander verbunden.

The main goal of the article is to briefly review the difference between analytical and synthetic in Hegel's philosophy, as well as to determine whether this philosopher was a follower of Kant's philosophy or not. First, in the "Introduction" section, the difference between analytical and synthetic in Kant's philosophy is shown; moreover, Kant's influence on Hegel and, generally, on the period in question and the conclusions of both scientists on this issue are analyzed. In the article, the main features of (...) Hegel's and Kant's worldviews and some conclusions related to the pair of concepts in Hegel's philosophy, i.e., analytical and synthetic concepts, are examined. In the conclusion of the article, Hegel's main philosophical views are identified, and the possibility of resolving the difference between analytical and synthetic through dialectical judgment is put forward.

In exact epistemology Immanuel Kant’s statement on the priority of application of cognitive faculties is detailed as an intellectual process. Empirical regularities of the JSM–method of automated support for research are synthetic a posteriori judgements. Theoretical intelligence is primary, and its aspects are understanding (Verstand) and mind (Gemüt). The conditions of possible experience in Kant’s sense are implemented in the JSM–method of ASR in intelligent systems. And the JSM–method itself is the transcendental logic of artificial intelligence using two theories (...) of truth, the coherence theory and the correspondence theory. Exact epistemology, which is exact neo-Kantianism, can be naturally considered as a reflection of information society culture on its civilizational (technological) aspects. (shrink)

Three classic distinctions specify that truths can be necessary versus contingent,analytic versus synthetic, and a priori versus a posteriori. The philosopher reading this article knows very well both how useful and ordinary such distinctions are in our conceptual work and that they have been subject to many and detailed debates, especially the last two. In the following pages, I do not wish to discuss how far they may be tenable. I shall assume that, if they are reasonable (...) and non problematic in some ordinary cases, then they can be used in order to understand what kind of knowledge the maker’s knowledge is. By this I mean the sort of knowledge that Alice enjoys when she holds the information that Bob’s coffee is sweetened because she just put two spoons of sugar in it herself. The maker’s knowledge tradition is quite important but it is not mainstream in modern and analytic epistemology and lacks grounding in terms of exactly what sort of knowledge one is talking about. My suggestion is that this grounding can be provided by a minimalist approach, based on an information-theoretical analysis. In the article, I argue that we need to decouple a fourth distinction, namely informative versus uninformative, from the previous three and, in particular, from its implicit association with analytic versus synthetic and a priori versus a posteriori; such a decoupling facilitates, and is facilitated by, moving from a monoagent to a multiagent approach: the distinctions qualify a proposition, a message, or some information not just in themselves but relationally, with respect to an informational agent; the decoupling and the multiagent approach enable a re-mapping of currently available positions in epistemology on these four dichotomies; within such a re-mapping, two positions, capturing the nature of a witness’ knowledge and of a maker’s knowledge, can best be described as contingent, synthetic, a posteriori, and uninformative and as contingent, synthetic, weakly a priori, and uninformative respectively. In the conclusion, I indicate why the analysis of the maker’s knowledge has important consequences in all those cases in which the poietic intervention on a system determines the truth of the model of that system.

Although Łukasiewicz and Quine do not share many common views, they agreed on one important point in the 1950s: they both denied the distinction between empirical and a priori sciences. This agreement might be surprising as this denial was rather controversial at that time. This paper focuses on Quine’s and Łukasiewicz’s denials of the distinction between empirical and a priori sciences, and proposes three possible answers to the question of why both formulated the same conclusion at a similar (...) time. Firstly, it discusses Quine’s possible influence on Łukasiewicz as Łukasiewicz agreed with Quine’s criticism of modality at that time. Secondly, it considers the possibility that Quine was affected by Łukasiewicz via his debates with Łukasiewicz’s student, Tarski. Lastly, it takes into account the possibility that both philosophers were inspired by an external source, namely the rise of quantum mechanics. (shrink)

I defend Kant’s definition of analyticity in terms of concept “containment”, which has engendered widespread scepticism. Kant deployed a clear, technical notion of containment based on ideas standard within traditional logic, notably genus/species hierarchies formed via logical division. Kant’s analytic/synthetic distinction thereby undermines the logico-metaphysical system of Christian Wolff, showing that the Wolffian paradigm lacks the expressive power even to represent essential knowledge, including elementary mathematics, and so cannot provide an adequate system of philosophy. The results clarify the extent (...) to which analyticity sensu Kant can illuminate the problem of a priori knowledge generally. (shrink)

The present paper deals with the ontological status of numbers and considers Frege ́s proposal in Grundlagen upon the background of the Post-Kantian semantic turn in analytical philosophy. Through a more systematic study of his philosophical premises, it comes to unearth a first level paradox that would unset earlier still than it was exposed by Russell. It then studies an alternative path, that departin1g from Frege’s initial premises, drives to a conception of numbers as synthetic a priori in a (...) more Kantian sense. On this basis, it tentatively explores a possible derivation of basic logical rules on their behalf, suggesting a more rudimentary basis to inferential thinking, which supports reconsidering the difference between logical thinking and AI. Finally, it reflects upon the contributions of this approach to the problem of the a priori. (shrink)

The received view in the history of the philosophy of psychology is that the logical positivists—Carnap and Hempel in particular—endorsed the position commonly known as “logical” or “analytical” behaviourism, according to which the relations between psychological statements and the physical-behavioural statements intended to give their meaning are analytic and knowable a priori. This chapter argues that this is sheer legend: most, if not all, such relations were viewed by the logical positivists as synthetic and knowable only a (...) class='Hi'>posteriori. It then traces the origins of the legend to the logical positivists’ idiosyncratic extensional or at best weakly intensional use of what are now considered crucially strongly intensional semantic notions, such as “translation,” “meaning” and their cognates, focussing on a particular instance of this latter phenomenon, arguing that a conflation of explicit definition and analyticity may be the chief source of the legend.

A neo-Kantian debate within analytic philosophy, in our reading, would evaluate thevalue of the following question: how the codification of the elements of a representation creates spaces of identification to theorize the possibilities oftruth, in two fields, the analytical and in the synthetic? In the analytic, the theory involves theability to conceptually interpret relations of possibility and impossibility; in the synthetic, thetheory involves the extra-conceptual supplementation of the alignment with the verifiers,providing a measure to encode the semantic contribution (...) of both experience simpliciter andexperience with concepts, made by schemas, analogical systems, etc. We suggest revitalizingthe theory of a priori syntheses, dialoguing with Kantian aspects of Husserl’s SixthInvestigation and confronting the orthodox semantics of empiricist inspiration.Although, in large part, a theory of judgments is equivalent to a dynamic production of models,simplifications and analogies, the focus on the production of synthetic and a priori judgmentspresents some independent problems, which, in our reading, would enrich the universe ofanalytic philosophy and would facilitate the reading of the development of the pragmatic shiftphase, which took place in the second half of the 20th century.Keywords: synthesis a priori; semantics; pragmatism.
