El rigor en pensar la vida psíquica le lleva a Leibniz a disociar la percepción de la con­ciencia, rompiendo con la tradición filosófica, carente de la idea de una vida psíquica incons­ciente. Nuestro conocimiento no se limita a la “apercepción” o percepción consciente, sino que alcanza una mayor profundidad. Desarrolla Leibniz una teoría puntillista de la sensa­ción, un hormigueo incesante de innumerables percepciones individuales imperceptibles componen toda percepción consciente.

G. W. Leibniz on Making Knowledge Sensible · G. W. Leibniz’s contribution to logic and a propositional theory of truth, based on the idea that concepts are composed of definitional notes, has been considered the core of his philosophical system and metaphysics. However, Leibniz thought that there are other forms of knowledge that are perceptual and, therefore, non-propositional and non-conceptual. This essay explores forms of non-conceptual knowledge and argues that they depend on the imagination. Despite the distinction between conceptual (...) and non-conceptual forms of knowledge, there are two senses in which conceptual knowledge depends on non-conceptual knowledge : there is a constitutive sense in which non-conceptual knowledge has a constitutive function because it allows one to conceive of beings in concreto, and thus anchors human knowledge to reality ; there is a second sense in which non-conceptual knowledge has the function of making imaginable intellectual concepts that could not be other- wise represented by the human mind. The essay shows that these functions are interrelated. (shrink)

This paper discusses Leibniz's views on apperception, especially in the context of this pseudo-dialogue with John Locke, An Essay Concerning Human Understanding. I emphasize the role of attention in the process of becoming conscious of a perception.

NICHOLASCAPALDI Queens College, CUNY Die Auseinandersetzung yon ldealismus und Realismus in Fichtes Wissenscha/tslehre. By Ingeborg Schfissler. (Frankfurt am Main: Vittorio Klostermann, 1972. Pp. 182. DM 24.50) For Fichte scholars this closely argued and well organized study of the foundations of Fichte's Wissenscha/tslehre is simply a must. American philosophers generally, however, will not become Fichte enthusiasts after reading this book. But this is not the fault of the authoress, but of Fichte. The key question which Dr. SchiJssler raises is, What role does realism play in Fichte's transcendental idealism? With this question in mind she examines Fichte's "foundation of the entire theory of science" of 1794-1795 and related matters, and the "theory of science" of 1804, together with the lecture of 1813. As Fichte originally saw the task of philosophy it was to explain theoretical, i.e., scientific, consciousness in terms of its own foundation. In 1804, however, the task was conceived as presentation of absolute truth; and in 1813, Fichte tried to understand the theory of science as a theory of appearances. Dr. Schfissler's thesis is that all three approaches are necessary; that, in fact, the changes in Fichte's conception of what a theory of science is or ought to be are grounded in the nature of transcendental philosophy itself. The book is not something one reads for relaxation; its sustained and detailed arguments militate against that. But it is a highly illuminating study, and well worth the effort of careful analysis. W. H. WE~mSTBR Florida State University The Manifold in Perception. Theories of Art.from Kant to Hildebrand. By Michael Pedro. (Oxford: Clarendon Press, 1972. Oxford-Warburg Studies) This is a survey of theories of art of Kant, Schiller, Herbart, Hildebrand, Schopenhauer and Fiedler. One may question the value of a re-statement of this sort, over simply another reading of the works of the authors themselves. Pedro's answer may be found in the Preface and again in a more extended statement in the conclusion. "German aesthetic theory from Kant through to the end of the nineteenth century seemed to contain valuable critical ideas quite absent from contemporary philosophical writing." Pedro's attempt has been to "re-locate notions in current use, like 'aesthetic detachment', within the sustained systematic discourse of which they were once part. This seemed a way both of uncovering a number of assumptions which have been constraining writing on art for some time, and of clarifying a number of crucial insights of earlier theorists." The author's account is almost entirely expository, its negative critical questions being limited almost exclusively to Herbart. Yet even here, when the author indicates that Herbart's theory of mind "exhibits certain very basic logical difficulties," he adds that 538 HISTORY OF PHILOSOPHY "they are difficulties which have a particular importance in the discussion of art.... " Podro's clarification is largely made through the asking of questions which the authors themselves did not ask and then suggesting answers to these questions in the light of what the authors did say. The two chapters on Schiller form the core of the book. Schiller's theory of art and aesthetic education of man is placed as central to Podro's account of an aesthetic tradition beginning with Kant and ending with Fiedler. The "tradition" detailed in Podro's book is described as having two underlying assumptions. The first was that any account of art must indicate distinctive or at least characteristic uses of our perception, uses which if not exclusive to art are at least necessary to it, and which are seen in art in a particularly striking way. The second assumption was that art involves our attitudes, in the sense of our serious purposes as... (shrink)

Guided by key insights of the four great philosophers mentioned in the title, here, in review of and expanding on our earlier work (Burchard, 2005, 2011), we present an exposition of the role played by language, & in the broader sense, λογοζ, the Logos, in how the CNS, the brain, is running the human being. Evolution by neural Darwinism has been forcing the linguistic nature of mind, enabling it to overcome & exploit the cognitive gap between an animal and its (...) world by recognizing environmental structures. Our work was greatly influenced by Heidegger’s lecture notes on metaphysics (Heidegger, 1935). We found agreement with recent progress in neuroscience, but also mathematical foundations of language theory, equating Logos with the mathematical concept of structure. The mystery of perception across the gap is analyzed as radiation and molecules impinging on sensory neurons that carry linguistic information about gross environmental structures, and only remotely about the physical reality of elementary particles. The most important logical brain function is Ego or Self, guiding the workings of the brain as a logos machine. Ego or Self operates from neurons in frontopolar cortex with global receptive fields. The logos machine can function only by availing itself of global context, its internally stored noumenal cosmos NK, and the categorical-conceptual apparatus CCA, updated continually through the neural default mode network (Raichle, 2005). In the Transcendental Deduction, Immanuel Kant discovered that Ego or Self is responsible for conscious control in perception relying on concepts & categories for a fitting percept to be incorporated intoNK. The entire CNS runs as a “movie-in-the-brain” (Parvizi & Damasio, 2001), at peak speed processing simultaneously in a series of cortical centers a stack of up to twelve frames in gamma rhythm of 25 ms intervals. We equate global context, or NK, with our human world, Heidegger’s Dasein being-in-the-world, and are able to demonstrate that the great philosopher in EM parallels neuro-science concerning the human mind.

This book is a systematic reappraisal of Leibniz’s philosophy of mind. The main argument of this book is easy to state: Leibniz offers a fully natural theory of mind. In today’s philosophical climate, in which much effort has been put into discovering a naturalized theory of mind, Leibniz’s efforts to reach a similar goal 300 years earlier will provide a critical stance from which we can assess our own theories. But while the goals might be similar, the content (...) of Leibniz’s theory significantly diverges from the majority of today’s theories. Leibniz’s philosophy of mind meets the standards of what he would regard as a fully natural theory. Perhaps surprisingly, Leibniz’s theological commitments yield a thoroughgoing naturalizing methodology: the properties of an object are explicable in term of the object’s nature. This book argues that Leibniz pursued his philosophy of mind with this methodology in hand. If we keep this commitment to a naturalizing project in mind, then we will find in Leibniz a rich and interesting philosophy of mind. -/- This book provides an account of Leibniz’s naturalizing constraints and traces them through Leibniz’s philosophy of mind. It covers issues relating to mental representation, perception, sensation, consciousness, memory, and moral identity. (shrink)

In this essay, our goal is to discover science in Martin Heidegger's Introduction to Metaphysics, lecture notes for his 1935 summer semester course, because, after all, his subject is metaphysica generalis, or ontology, and this could be construed as a theory of the human brain. Here, by means of verbatim quotes from his text, we attempt to show that indeed these lectures can be viewed as suggestion for an objective scientific theory of human perception, the human capacity for (...) deciphering phenomena, ie. hermeneutics in its broadest sense. His added notes from the 1953 edition, all of which are comments, not corrections, imply that he never abandoned these thoughts on metaphysics, despite all of his utterances about a need to overcome it, and their popular interpretations to that effect. In his presentation, he further develops the colorful and intuitive style, an hermeneutic language, that he had created in his earlier work Being and Time. Of human existence he speaks in such expressions as being-there -- ``Dasein" -- and being-in-the-world, the latter term no longer explicit in the 1935 lectures. The lectures can be read as a pre-scientific analysis of how man, being-there, perceives his environment, artfully managing to deal with the manifold challenges posed by the phenomenal structures of the universe. Man attentively recognizes and deciphers their pre-linguistic contents and, while trying to make sense of it all, puts into words his awareness. There are numerous passages in Heidegger's work where he in fairly concrete terms provides us with hints for a perceptive science that, as it turns out and is demonstrated below in this essay, can be explained in terms of recent advances in neuroscience. It would be implausible, even unthinkable, unimaginable, for there not to be found essential agreement between on one hand his philosophical insights gained by hermeneutics of Dasein, into how our brain functions to let us know what's happening & on the other hand, scientific discoveries obtained through anatomy, EEG, fMRI, TMS, electrode implants, etc, of brain structures & functions employed in perception of the momentary scene. A nexus between science and philosophy is provided in Heidegger's definitive treatment of the Logos, here interpreted as a structural version of Platonic forms (Burchard, 2014). This allows for neurolinguistic brain functions to serve as meta-context for Heidegger's being-in-the-world. The logical functions of Dasein's anatomical brain are performed by the logos machine, formerly the human soul, using top-down processing based on a global context, the noumenal cosmos which humans maintain internally. Heidegger's 1942/43 winter semester lectures Parmenides extend in unbroken fashion his 1935 work, proving that he never abandoned, as is widely claimed, his metaphysical avenue of thought. (shrink)

"The intent of this book," according to the author, "is to document the existence in man of two major modes of consciousness: one is analytic, the other holistic." They are sometimes called, he observes, "the ‘rational’ and ‘intuitive’ sides of man." In this connection, he adduces Roger Bacon’s apposite dictum: "There are two modes of knowing, those of argument and experience." A notable recent finding on the brain correlates of reason and intuition is summarized in the present book as follows: (...) "The left hemisphere of the cortex, which subtends language and mathematics, seems to process information in a linear, sequential manner... The right side of the cortex processes its input more as a ‘patterned whole'." That is, science, for example, uses the left side of the brain, while nonrational meditation exercises, procedures for expansion and concentration of consciousness, and the mystic experience, for example, involve the right side. The author sympathetically describes and analyzes a large variety of meditation methods as illustrating the intuitive path to knowledge, reports pertinent findings on biofeedback phenomena and other scientific grapplings with awareness disciplines and nonattachment systems, and concludes with a plea to scientific psychologists to train themselves rigorously in esoteric techniques. He also suggests, à propos of the "unitive" character of the mystic experience: "A shift toward a consciousness of the interconnectedness of life... might enable us to take those ’selfless’ steps that could begin to solve our collective problems." For philosophers who are open-minded on other ways of studying or making contact with reality than controlled observation, analysis, induction, theory-making, verification, and revision, this book should prove useful, both because it provides a rich collection of data and because it suggests directions for achieving a synoptic view.—W.

Impressions, energy radiated by phenomena in the momentary environmental scene, enter sensory neurons, creating in afferent nerves a data stream. Following Kant, by our inner sense the mind perceives its own thoughts as it ties together sense data into an internalized scene. The mind, residing in the brain, logically a Language Machine, processes and stores items as coded grammatical entities. Kantian synthetic unity in the linguistic brain is able to deliver our experience of the scene as we appear to see (...) it. Uniquely, the brain records its own history, synthesizing a Movie-in-the-Brain, called the Noumenal Cosmos. Attempting thereby to represent the actual Universe, this makes for a sovereign brain that governs itself. The brain is domicile of an Ego, with its selfhood at stake at all times. Yet, it can know itself only by its actions, in which it appears as an actor in its own movie. Phenomena enter garbled, as confused apparitions, and must be put in good form using top–down feedback control by Ego, so that each movie frame makes rational sense within the overall context of the Noumenal Cosmos. A stack of frames is processed typically in 40 Hz rhythm with 300 ms process time each, for about 12 in the stack at any time. Successive neural centers are processing the stack in the brain assembly line, based on data from increasingly global receptive fields. Ego stitches together the movie frames, but only the top frame is in consciousness for 25 ms. The top frame contains the whole scene where the Ego makes an appearance as the actor that imposes Kantian synthetic unity on the scene, merely an assembly of grammatical texts, in a system-internal coded process language, fitting the scene into the Noumenal Cosmos. But Ego observes Ego only to the extent permitted by the objectivity rule, only what it does and thinks, not its true face. From the Noumenal Cosmos, the Ego receives grammatical messages in the internal sense code. They are integrated into a whole in the reaction of the Ego to the momentary scene. The voluntary nature of Ego’s decisions is explained, based on its ability to code in advance its own actions sequentially in time, as it sees fit with a view to an orderly Noumenal Cosmos, records of code being arranged spatially in neural structures.

Context: Phenomenology and the enactive approach pose a unique challenge to dream research: during sleep one seems to be relatively disconnected from both world and body. Movement and perception, prerequisites for sensorimotor subjectivity, are restricted; the dreamer’s experience is turned inwards. In cognitive neurosciences, on the other hand, the generally accepted approach holds that dream formation is a direct result of neural activations in the absence of perception, and dreaming is often equated with “delusions.” Problem: Can enactivism and phenomenology account (...) for the variety of dream experiences? What kinds of experiential and empirical approaches are required in order to probe into dreaming subjectivity? Investigating qualities of perception, sensation, and embodiment in dreams, as well as the relationship between the dream-world and waking-world requires a step away from a delusional or altered-state framework of dream formation and a step toward an enactive integrative approach. Method: In this article, we will focus on the “depth” of dream experiences, i.e., what is possible in the dream state. Our article is divided into two parts: a theoretical framework for approaching dreaming from an enactive cognition standpoint; and discussion of the role and strategies for experimentation on dreaming. Based on phenomenology and theories of enactivism, we will argue for the primacy of subjectivity and imagination in the formation of lived experience. Results: We propose that neurophenomenology of dreaming is a nascent discipline that requires rethinking the relative role of third-, first- and second-person methodologies, and that a paradigm shift is required in order to investigate dreaming as a phenomenon on a continuum of conscious phenomena as opposed to a break from or an alteration of consciousness. Implications: Dream science, as part of the larger enterprise of consciousness and subjectivity studies, can be included in the enactive framework. This implies that dream experiences are neither passively lived nor functionally disconnected from dreamers’ world and body. We propose the basis and some concrete strategies for an empirical enactive neurophenomenology of dreaming. We conclude that investigating dream experiences can illuminate qualities of subjective perception and relation to the world, and thus challenge the traditional subject-object juxtaposition. Constructivist content: This article argues for an interdisciplinary enactive cognitive science approach to dream studies. (shrink)

This thesis is about experiential content: what it is; what kind of account can be given of it. I am concerned with identifying and attacking one main view - I call it the inferentialist proposal. This account is central to the philosophy of mind, epistemology and philosophy of science and perception. I claim, however, that it needs to be recast into something far more subtle and enriched, and I attempt to provide a better alternative in these pages. The inferentialist proposal (...) holds that experiential content is necessarily under¬pinned by sophisticated cognitive influences. My alternative, the continuum theory, holds that these influences are relevant to experience only at certain levels of organisation and that at other levels there are contents which such features do not capture at all. Central to my account is that there are degrees to which cognitive influences affect experiential content; indeed, for the most part, experience is an amalgam of both inferential and non-inferential features. I claim that the inferentialist proposal is fundamentally flawed and deserves replacement, and I argue that my alternative fills the hollow that remains. The thesis is divided into four sections. In Part I, Chapter 1, I introduce two traditionally rival views of experiential content. In Chapter 2, I develop my continuum alternative. Chapter 3 assesses the relationship between experience and language, while Chapter 4 explores the relationship between beliefs and experience. The overall argument is that it has been a mistake to understand experience simply in inferential or non-inferential terms. In Part II, I examine the structure of mental content. Chapter 5 is concerned with the kinds of experiences which escape the inferentialist analysis. Chapter 6 considers Kant’s metaphysic of experience counterpointed to Lorenz’s reading of his work in the light of evolutionary biology. Chapter 7 treats animal experience in relation to the continuum view I am developing, while Chapter 8 reviews Fodor’s contribution to perceptual psychology. It is argued that the view of experiential content being developed is both consistent with empirical data on informationally local perceptual sub-systems, but also accords well with evolutionary theory and a naturalist interpretation of Kant’s taxonomy. Part III deals with inferentialism in the philosophy of science. In Chapter 9, I assess the theory dependence of observation thesis as it is advanced by Paul Feyerabend. I bring out of his account a subtle confusion concerning the importance of inference in the context of scientific inquiry. Part IV deals with the issue of experience in the philosophy of mind. In Chapter 10, I look at Wilfred Sellars’s attack on sense data theories. Chapter 11 confronts Paul Churchland’s treatment of ‘folk psychology’ while Chapter 12 isolates the issue of experiential qualia and the position of property dualism. I offer a critical review of Thomas Nagel’s work in this chapter and claim that his position can be read in a way which is consistent with the continuum account I am developing. I conclude the thesis in the usual fashion with a summary of the central claims. (shrink)

Comparisons are drawn between two theories of visual perception and two modes of information processing. Characteristics delineating dorsal and ventral visual systems lack internal consistency, probably because they are not completely separable. Mechanism is inherent when distinguishing these systems, and becomes more apparent with different processing domains. What is lacking is a more explicit means of linking these theories.

In lieu of an abstract, here is a brief excerpt of the content:The Concept of Experience in Locke and Hume JOHN W. YOLTON THE EMPIRICISTPROGRAM has been designed to show that all conscious experience "comes from" unconscious encounters with the environment, and that all intellectual contents (concepts, ideas) derive from some conscious experiential component. Some empiricists, but not all, have also argued that experience reports about the world. A strict empiricism would have to reject this latter claim, as Hume did, (...) although even to consider the possibility of knowledge being related to an external world is to operate on a reflective level, to seek to make sense of experience. The distinction between an account of the nature of experience--its structure, relations, and contents-and explanations of experience--its causal antecedents, its reference--is an important one. The phrase "the concept of experience" refers to the use made of some account of experience. The concept of experience need not be restricted to the experiential contents. Thus, Locke sought to show how experience is of the world, Hume tried to show how experience restricts our valid conceptual contents to certain sorts of ideas, eliminating others. Any account of experience will already be a conceptualization of experience: it must be made from the reflective level. But the account need be no more than a careful record of how the organism comes to the conscious level. Of course, such an account cannot be a straightforward description, since we cannot directly observe all of the processes operating in the production of awareness. The psychology of awareness is forced to extrapolate and conjecture. Nevertheless, we can still distinguish the psychological or descriptive account of experience from the metaphysical use made of that account. It is my purpose here to explore the accounts given and the uses made of experience by two representative empiricists, that is, by philosophers whom we look upon as advancing the empiricist metaphysic of experience. Locke's Derivation o[ Ideas From Experience Locke claimed that all mental contents come from two sources, sensory experience of the world and introspective awareness of our mental processes. The program of Book II of his Essay was to exemplify, by reference to a [53] 54 HISTORY OF PHILOSOPHY number of different ideas and concepts, this derivation of our mental contents. The counter claim for Locke was innatism, the view held by many of his contemporaries and refuted in the first book of his Essay. In order to appreciate what Locke's alternative to innatism was, we must try to discover what the program of derivation of ideas amounts to in his epistemology and what precisely he understood by the term "experience." We must first note that he offers the program of derivation in conjunction with a complex theory of mental operations. H. H. Price has remarked that it is "historically false that the empiricist thought the human mind passive. It would be more just to criticize them for making it more active than it can possibly be.''1 Mental processes play a most active and decisive role in the genesis of all ideas in Locke's account. In the case of simple ideas of sense even, the mind must be attentive to what the senses report, else that report will go unrecorded, or be recorded only at the neural level (II, I, #6, #8, and II, IX, #3). Locke frequently draws the distinction between mental contents or processes and physical processes. In the "Epistle to the Reader," where he defines "idea," he is careful to distinguish idea from the sound we "use as a sign of it." In I, I, #2 he draws a distinction between the "physical consideration of the mind" and the non-physical consideration, although he does not have a name for the latter. He also speaks there of "sensations by our organs" and "ideas in our understanding." Locke disclaimed any intention of going into the physical account of sensation. He simply accepted the current corpuscular theory. But although he is not always as precise as we would be about the physical and physiological levels of encounter, in distinction from the mental levels, he does hold to this division. II, I, #3, for instance, speaks of the senses conveying "into the mind" several "distinct perceptions... (shrink)

The essay brings a summation of human efforts seeking to understand our existence. Plato and Kant & cognitive science complete reduction of philosophy to a neural mechanism, evolved along elementary Darwinian principles. Plato in his famous Cave Allegory explains that between reality and our experience of it there exists a great chasm, a metaphysical gap, fully confirmed through particle-wave duality of quantum physics. Kant found that we have two kinds of perception, two senses: By the spatial outer sense we perceive (...) phenomena, objects in space. Our temporal inner sense lets us perceive our inner state, noumena . Kant's two senses are fully confirmed through bilateral brain duality of cognitive science. The bilateral brain serves inner, temporal sense, logic & noumena in the left hemisphere. The right brain half is for the outer, spatial sense, geometry & phenomena. We form a whole system, a bilateral interior cosmos, a kind of world model, expressing what may lie beyond the metaphysical gap. In the right brain we build a phenomenal cosmos, to resemble the outer environment. In the brain's left hemisphere a noumenal cosmos, a model of our private world including Saint Teresa of Avila's castillo interior. The cosmos is regularly updated with novel sense data integrated into our memory banks. This was recognized early by Helmholtz (1860s). Our lives, health & well-being depend on us keeping our interior cosmos in good order. This used to be seen as saving one's precious soul from perdition. While we endeavour to keep our phenomenal cosmos neat & orderly by protecting the environment from harm, our noumenal cosmos to be livable requires us to engage in ethical conduct. This bilateral cosmos is responsible for our common sense judgment power, that we depend on for being able to lead a good & benign life. The 200 million neurons of BA10 in the prefrontal lobe have global access to the interior cosmos, & apply massive feedback to identify environmental conditions rapidly. The global access also gives conscious presence of the individual to itself, all that is present in the interior cosmos, for total freedom of action. In the left brain private ego, we are guarded by faith in divine mercy, & guided to choose the best course of action, able to survive under the most adverse conditions. For this, we receive directions from the Holy Ghost in Saint Teresa's castillo interior. (shrink)

In the absence of any plausible reductionist account of consciousness in nonmentalistic terms, the HOT theory says that the best explanation for what makes a mental state conscious is that it is accompanied by a thought (or awareness) that one is in that state. I discuss HOT theory with special attention to how Leibnizian theses can help support it and how it can shed light on Leibniz's theory of perception, apperception, and consciousness. It will become clear how (...) treating Leibniz as a HOT theorist can solve some of the problems he faced and some of the puzzles posed by commentators, e.g. animal mentality and the role of reason and memory in self-consciousness.

For over a century and certainly since single-unit recordings in the 1960s the theory of perception that has dominated thinking and research, with implications for the understanding of all other cognitive domains, entails a neocortical process of progressive assembly from V-1 to V-4 leading to object-construction and secondary spatial updating and recognition. In recent years, however, difficulties with the theory have emerged in neurophysiological research though a compelling alternative has not been forcefully argued. It is the purpose of (...) this paper to review the main features of the microgenetic account of perception, which inverts standard theory 180 degrees, and aligns the perceptual process with patterns of evolutionary growth. This theory developed on clinical study, and perhaps for this reason has not received sufficient attention, in mainstream cognitive and affective neuroscience, though it provides an account not only of perception but of stages in memory, imagery, the present moment, and the mind/brain state.

This chapter contains sections titled: Socratic Dialogues Phaedo Republic Timaeus Theaetetus Sophist Philebus Seventh Letter and Definitions Overview Note.

Chemistry and dynamics are closely related in G.W. Leibniz's thinking, from the corpuscularism of his youth to the theory of conspiracy movements that he proposes in his later years. Despite the importance of chemistry and chemical thought in Leibniz's philosophy, interpreters have not paid enough attention to this subject, especially in the recent decades. This work aims to contribute to filling this gap in Leibnizian studies. In this first part of the work I will expose the theory of (...) matter that the young Leibniz conceives under the influence of chemical corpuscularism. Leibniz uses R. Boyle's interpretation of the Aristotelian idea of form in order to give an explanation of the unity and cohesion of bodies. As opposed to the Cartesians, Leibniz puts forth the idea of a dependence between the variables of extension, movement and figure, without losing analytical clarity and with the aim of extending the explanatory power of physics to natural phenomena difficult to approach by Cartesian mechanics.

This volume contains papers that represent Leibniz’s early thoughts on the problem of evil, centering on a dialogue, the Confessio philosophi, in which he formulates a general account of God’s relation to sin and evil that becomes a fixture in his thinking. How can God be understood to be the ultimate cause, asks Leibniz, without God being considered as the author of sin, a conclusion incompatible with God’s holiness? Leibniz’s attempts to justify the way of God to humans lead him (...) to deep discussion of related topics: the nature of free choice, the problems of necessitarianism and fatalism, the nature of divine justice and holiness. All but one of the writings presented here are available in English for the first time. (shrink)

The topic of my paper is the virtual controversy between Leibniz and Lockeover concepts and ideas. At the end of the 17th century John Locke made a crucial contribution to semantics and philosophy: An Essay Concerning Human Understanding. The work represents a decisive turning point for the discussion about ideas and innatism. Indeed, Locke’s aim was to dismantle the Cartesian theory according to which ideas are innate in our soul. Against this onto-epistemological thesis, Locke maintains that all our knowledge (...) starts off with experience: ideas are mental representations depending on subjects’ sensual experiences and reflection skills. Some years later, in his notes on Locke’s Essay, Leibniz writes that Locke dealt with a fundamental topic: human understanding and the limits of human knowledge (NE p. 4). All we can find out about the world is determined by answering the question about what we can know; nonetheless, Leibniz argues in favor of innate ideas. My thesis is that in his opinion Locke’s empiricism can be conciliated with the assumption that there are innate ideas. (shrink)

The chapter focuses on attributions of the transparency of thought to early modern figures, most notably Descartes. Many recent philosophers assume that Descartes believed the mind to be “transparent”: since all mental states are conscious, we are therefore aware of them all, and indeed incorrigibly know them all. Descartes, and Berkeley too, do make statements that seem to endorse both aspects of the transparency theses (awareness of all mental states; incorrigibility). However, they also make systematic theoretical statements that directly countenance (...) “unnoticed” thoughts or mental states, that is, thoughts or mental states of which the subject is unaware and has no knowledge. Descartes, having identified the essence of mind with thought or representation, distinguishes bare states of mind from states of which we have reflective awareness, thereby providing a theoretical tool for understanding both his seeming endorsement of transparency and his actual denial of it: Descartes distinguished between a basic perceptual state, or a basic awareness, and reflectively conscious states that involve explicit noticing and cognizing on the part of the subject. Leibniz (as is better known) directly endorsed a similar distinction between bare perception and reflective consciousness, using the term “perception” for the first and “apperception” for the second. In these cases, bare perceptions are not transparently available to the subject, and so in fact the subject does not have knowledge, hence does not have incorrigible knowledge, of all its occurrent mental states. This chapter gives evidence to support these claims; elaborates the complex psychology of the subject found in Descartes and other early moderns; and notes some ways in which these early moderns contributed to the genesis of the modern subject. Finally, it compares McDowell’s conception of the Cartesian mind with the conceptions of mind found in the writings of Descartes, Berkeley, and Leibniz, finding that his characterization caricatures the positions of early modern philosophers. McDowell's characterization has four elements: consciousness as essence of mind; intentionality as exclusively mental; the veil of perception; and the transparency of mind. Only the second point, about intentionality, fully fits Descartes. As a consequence of his own misdirection, McDowell misses the actual basis of his difficulty in connecting mind with world, which arises from a point of agreement between him and Descartes: the removal of intentionality from material sensory systems. But whereas Descartes could relocate (nonconceptual) sensory intentionality in mental states, McDowell is left to account for it with his overly cognitivized scheme of perceptual content as exclusively conceptual.

Is Leibnizian dynamics the New Physics sought in his youth to provide a solution to the problem of body unity/composition? This question can only be answered tentatively. The thesis that I will develop in this second part is that chemical-combinatoria project is not complete without some ideas of dynamics. The idea of form, which since the early Leibniz’s philosophy is projected to give a foundation to the corpuscular theory, only reaches this objective with the theory of conspiring movements (...) that Leibniz develops as the last phase of his dynamics. Within this general objective, this second part develops three secondary issues of importance: Leibniz’s emergent and realistic position, his theory of compounds and the interpretation of the Combinatoria or Characteristica project as a science of forms.

In lieu of an abstract, here is a brief excerpt of the content:163 HUME'S THEORY OF MOTIVATION In this paper I shall defend a Humean theory of motivation. But first I should like to examine some of the standard criticisms of this theory and some alternative views that are currently in favour. Both in the Treatise and the Enguiry Hume maintains that reason alone never motivates action but always requires the cooperation of some separate, and separately identifiable (...) desire-factor in order to bring about action. What are Hume's grounds for this view? In the Treatise. Hume writes: 'Tis obvious, that when we have the prospect of pain or pleasure from any object, we feel a consequent emotion of aversion or propensity, and are carry 'd to avoid or embrace what will give us this uneasiness or satisfaction.... 'Tis from the prospect of pleasure or pain that the aversion or propensity arises towards any object.... This passage suggests that the way we (and Hume) know about the presence of the separate desire factor which he claims is always needed to motivate our every purposive action is by being directly aware of some desire-feeling, by introspection, each and every time we act. There is however a familiar objection to this argument: no doubt we sometimes are aware of a feeling of desire when we act, e.g., in cases where we are motivated by strong emotions. But much of the time when we act calmly or casually, after having deliberated 'in a cool hour', or when performing routine and trivial acts, we are not directly aware of any desire-feeling at the time of action. 164 Hume is not unaware of this objection -- in reply to it he invokes his notorious doctrine of the calm passions. He writes: 'Tis natural for one, that does not examine objects with a strict philosophic eye, to imagine, that those actions of the mind are entirely the same, which produce not a different sensation, and are not immediately distinguishable to the feeling and perception. Reason, for instance, exerts itself without producing any sensible emotion; and except in the more sublime disquisitions of philosophy, or in the frivolous subtilities of the schools, scarce ever conveys any pleasure or uneasiness. Hence it proceeds, that every action of the mind, which operates with the same calmness and tranquillity, is confounded with reason by all those, who judge of things from the first view and appearance. Now 'tis certain, there are certain calm desires and tendencies, which, tho' they be real passions, produce little emotion in the mind, and are more known by their effects than by the immediate feeling or sensation. These desires are of two kinds; either certain instincts originally implanted in our natures, such as benevolence and resentment, the love of life, and kindness to children; or the general appetite to good, and aversion to evil, consider 'd merely as such. When any of these passions are calm, and cause no disorder in the soul, they are very readily taken for the determination of reason, and are suppos'd to proceed from the same faculty, with that, which judges of truth and falshood. Their nature and principles have been suppos'd the same, because their sensations are not evidently different. (T 417) The most obvious application of this argument would be to cases of cool, seemingly passionless 165 deliberation: e.g., in the course of planning the family budget I set aside funds for the children's education. A cursory inspection (or recollection) of the contents of my conscious mind at the time of acting would reveal to me some purely rational considerations that I had in mind at the time. I had some thoughts at the time whose contents are (roughly) expressible in such words as "If I don't put aside so much per month over so many years we will never be able to see them all through university." But cursory introspection or recollection would not detect any separately identifiable desire-factor present to my conscious mind at the time. Considered philosophical examination, Hume assures us, will reveal one, a 'calm' one -- in this case calm 'kindness to children'. Less obviously, the calm-passions argument, most naturally applicable to cases of deliberation... (shrink)

We eat not only because it is necessary for us to, but also and much more because eating gives us pleasure.In this essay, I develop a case for G. W. Leibniz as our first modern food philosopher. It is in his theory of perception and in his culinary examples that I find the most convincing evidence, especially when I contrast them with Locke and Hume’s account of perception with reference to food. In the process, Leibniz expanded aesthetic perception to (...) include nature and food. He did not draw a distinction between ordinary or regular perception and aesthetic perception; perceiving smells and tastes are similar to perceiving colors—both have structures,2 but more on..

This volume is a critical edition of the ten-year correspondence between Gottfried Wilhelm Leibniz, one of Europe’s most influential early modern thinkers, and Bartholomew Des Bosses, a Jesuit theologian who was keen to bring together Leibniz’s philosophy and the Aristotelian philosophy and religious doctrines accepted by his order. The letters offer crucial insights into Leibniz’s final metaphysics and into the intellectual life of the eighteenth century. Brandon C. Look and Donald Rutherford present seventy-one of Leibniz’s and Des Bosses’s letters in (...) the original Latin and in careful English translation. Few of the letters have been translated into English before. The editors also provide extensive annotations, deletions, and marginalia from Leibniz’s various drafts, and a substantial introduction setting the context for the correspondence and analyzing the main philosophical issues.

This volume is a critical edition of the eight-year correspondence between Gottfried Wilhelm Leibniz and Burcher de Volder, professor of philosophy and mathematics at Leiden University. Containing the surviving correspondence between Leibniz and De Volder, the volume also presents a generous selection from the letters between Leibniz and his friend Johann Bernoulli, through whose intercession the correspondence began. Bernoulli acted as intermediary throughout, and the often candid discussions between Leibniz and Bernoulli provide illuminating background to the correspondence proper. Each of (...) the selections appears both in the original Latin and in English translation. (shrink)

This book is a collection of essays published by the author in the long run of about 20 years and is centered on the reconstruction of Leibniz’s logical calculi. All the essays have been revised for the present edition and some of them constituted the background for Lenzen’s first monograph on Leibniz’s logic. A feature common to all these essays is the vindication of the relevance and originality of Leibniz’s logical achievements. Lenzen manifests strong dissatisfaction with the evaluations of Leibniz’s (...) logic previously offered by interpreters like Louis Couturat, Clarence I. Lewis, Karl Dürr, William and Martha Kneale, and states that till now Leibniz’s results in the field of logic have been widely underestimated. The book contains a careful and detailed examination of almost all Leibniz’s papers on the logical calculus and it is based on the knowledge of a wide range of texts unknown to previous interpreters. Lenzen’s acquaintance with the entire corpus of Leibniz’s logical texts is impressive. Some chapters of the book in particular contain very solid and useful logical analyses. Chapter 7, for instance, includes the most profound account of Leibniz’s theory of negation I ever read. Chapter 8 presents in a very clear way Leibniz’s attempt to reduce traditional syllogistic to a calculus based on logical inclusion between terms. Chapter 14 is devoted to Leibniz’s a priori proof of the existence of God and presents the first edition of an important manuscript on the proof. On chapters 3 and 5 a series of convincing reasons are given to argue that Leibniz’s concept of ens does not have to be considered a constant in the logical calculus. In brief: this work discusses a wide range of topics in such a clear and learned way that it will surely become a reference book for scholars interested in the study of Leibniz’s logical papers in the forthcoming years.

In this book G. W. Leibniz presents not only his reflections on predestination and election but also a more detailed account of the problem of evil than is found in any of his other works apart from the _Theodicy_. Surprisingly, his _Dissertation on Predestination and Grace_ has never before been published in any form. Michael J. Murray's project of translating, editing, and providing commentary for the volume will therefore attract great interest among scholars and students of Leibniz's philosophy and theology. (...) Leibniz addresses such topics as free will, moral responsibility, divine causation, justice, punishment, divine foreknowledge, and human freedom, revealing crucial aspects of the genesis of his mature metaphysics and the theological motivations behind it.

Kann Gott tun, was er will oder will Gott, was seinem Wesen entspricht? Ist Gott an notwendige Prinzipien gebunden oder ist notwendig, was Gott dekretiert? Derartige Fragen nach dem Verhältnis von Modalitäten und Gotteskonzepten sind Bestandteil unzähliger Debatten und reichen weit in die Philosophie- und Theologiegeschichte zurück. Die vorliegende Studie untersucht zunächst die Modalmetaphysiken G.W. Leibniz', D. Lewis' und A. Plantingas samt ihren sehr unterschiedlichen ontologischen Voraussetzungen. Im Anschluss werden die in der gegenwärtigen analytisch-religionsphilosophischen Debatte dominanten Formen des Theismus analysiert: (...) der klassische und personale Theismus und der Panentheismus. Das Kernstück dieser Studie bildet die Analyse von Konsistenzen und Inkonsistenzen, die zutage treten, will man aus metaphysisch-ontologischen Gründen diese unterschiedlichen Formen des Theismus mit den Modaltheorien Lewis', Leibniz' oder Plantingas verbinden.

This paper discusses the debate over whether emotional expressions are spontaneous or intentional actions. We describe a variety of empirical evidence supporting these two possibilities. But we argue that the spontaneous-intentional distinction fails to explain the psychological dynamics of emotional expressions. We claim that a complex systems perspective on intentions, as self-organized critical states, may yield a unified view of emotional expressions as a consequence of situated action. This account simultaneously acknowledges the embodied status of environment, evolution, culture and mind (...) in theories of emotion. (shrink)

It is well known that Kant was stirred from his "dogmatic slumber" by the writings of David Hume. It is not well known that Hume had a similar effect upon his contemporary Thomas Reid. Yet it was Hume who led Reid to see that the path along which British Empiricism was moving might well end in Pyrrhonian skepticism-Hume's denial to the contrary. Interest in the writings of Reid has been increasing in recent years. One reason is that the range of (...) Reid's philosophical inquiry covers a number of areas which attract a good deal of attention today. Reid offers interesting and often significant insights into aspects of epistemology, philosophy of mind, aesthetics, and philosophy of action. His philosophy has contributed to the writings of such men as G. E. Moore, C. S. Peirce, R. Chisholm, P. Winch, to mention only a few. This new edition of An Inquiry Into the Human Mind follows closely upon the heels of new editions of Reid's Essays on the Active Powers of Man and Essays on the Intellectual Powers of Man, both of which appeared in 1969. In introducing this latest edition, Duggan chose to concentrate his attention upon one aspect of Reid's thought rather than offer a rapid and perhaps superficial treatment of the multifaceted thinking of this 18th century philosopher. Duggan's critical analysis of Reid's interpretation of sensation and perception is invaluable for introducing the reader to Reid's philosophical alternative to Hume. It was this alternative which came to be known as the philosophy of common sense.--W. P. G. (shrink)

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains-losses domain and high-low probability. Pay dissatisfaction (in the losses domain) incites dishonesty in the name of justice at the individual level. The Corruption Perceptions Index, CPI, signals a high-low probability of getting caught for dishonesty at the country level. We theorize that decision-makers adopt avaricious love-of-money (...) aspiration as a lens and frame dishonesty in the gains-losses domain (pay satisfaction-dissatisfaction, Level 1) and high-low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction mitigates dishonesty across nations consistently. Based on 6500 managers in 32 countries, our cross-level three-dimensional visualization offers the following discoveries. Under high aspiration conditions, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations, supporting the certainty effect. However, pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities, sustaining the possibility effect—maximizing expected utility. Under low aspiration conditions, high pay satisfaction consistently leads to low dishonesty, demonstrating risk aversion—achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations. We enhance the S-shaped Curve to three 3-D corruption surfaces across three levels of the global economic pyramid, providing novel insights into behavioral economics, business ethics, the environment, and responsibility.

This is an abridgement of the complete translation of the New Essays, first published in 1981, designed for use as a study text. The material extraneous to philosophy - more than a third of the original - and the glossary of notes have been cut and a philosophical introduction and bibliography of work on Leibniz have been provided by the translators. The marginal pagination has been retained for ease of cross-reference to the full edition. The work itself is an acknowledged (...) philosophical classic, in which Leibniz argues point by point with Locke's Essay Concerning Human Understanding. The result is the single most important confrontation between the philosophical traditions of rationalism and empiricism. It makes an extremely suitable focus for the study of Leibniz's thought and of those two traditions in relation to one another. (shrink)

Perceptual experience is often said to be transparent; that is, when we have a perceptual experience we seem to be aware of properties of the objects around us, and never seem to be aware of properties of the experience itself. This is a introspective fact. It is also often said that we can infer a metaphysical fact from this introspective fact, e.g. a fact about the nature of perceptual experience. A transparency theory fills in the details for these two (...) facts, and bridges the gap between them. We have three aims: to scrutinize Michael Tye’s transparency theory :137–151, 2002; Consciousness revisited: materialism without phenomenal concepts, MIT Press, Cambridge, 2009; Philos Stud 170:39–57, 2014a), introduce a new transparency theory, and advance a meta-theoretical hypothesis about the interest, and import, of transparency theories.
