3 "Re-thinking Hobbes's Materialistic and Mechanistic Projects " ROBERTARP I. Introduction In this paper I shall attempt to show that, despite his intention to formulate a thoroughly reductionistic and mechanistic philosophical system, Hobbes actu- ally fails on both accounts. First, I argue that Hobbes fails to be a consistent ontological reductionist, but his attempts at applying methodological reduction- ism fair much better. Then, I argue that Hobbes fails to be a strict mechanist since at times he seems to implicitly endorse the very Aristotelian/Scholastic categories he has explicitly rejected. Again, Hobbes's methodology appears mechanistic given its Galilean scope; however, his metaphysical views betray his views concerning the physics of the universe. In the end I maintain that such inconsistency, oversight and contradiction in his system is to be expected since Hobbes was, at once, philosopher and philosophical theologian existing on the cusp of the Scholastic and Modem worlds. II. Hobbes's materialistic project A. Materialism, Mechanism, Ontology and Methodology At the outset it is important to define and distinguish versions of materialism and mechanism.' A materialist thinks that all aspects of reality can be account- ed for in material terms. In the Oxford Dictionary of Philosophy Simon Blackburn defines materialism as the "view that the world is entirely composed of matter."2 Thomas Spragens saddles Hobbes with materialism when he claims ' I would like to thank the following persons for their valued criticisms, insights and support in the formulationof this paper: Richard Dees, Douglas Jesseph, Jack Marler, George Terzis and Catherine Wilson. 2 Simon Blackburn, The OxfordDictionary of Philosophy.(Oxford: Oxford UniversityPress, 1996), p. 233. Besides Blackburn's dictionary,there is a plethora of philosophicaldictionar- ies and encyclopediasthat define materialismand mechanism. A good place to begin is with a) The Cambridge Dictionary of Philosophy, ed. Robert Audi. (Cambridge: Cambridge UniversityPress, 1995)and b) The RoutledgeEncyclopedia of Philosophy,ed. Edward Craig. (London:Routledge, 1998). 3 that Hobbes "thought that the basic constituents of the universe, including nature, life and mind" were simply matter in motion.3 A mechanist tries to give an account of the basic workings of the universe in purely antecedent-conse- quent terms to the exclusion of teleological or finalistic explanations. This was the procedure generally adhered to by the early Modems; witness the philo- sophical systems of Descartes and Bacon with their poignant criticisms of tele- ology and finality found in Aristotle and the Scholastics.4 We can also distinguish between an ontological materialist and a method- ological materialist. An ontological materialist holds that reality is fundamen- tally material thereby ruling out the existence of anything supernatural or men- tal. Feuerbach, as well as Patricia and Paul Churchland are professed ontolog- ical materialists.' On the other hand, a methodological materialist is someone whose attitude, world-view or epistemic tendency is toward a favoring of onto- logical materialism. Generally, methodological materialists will always try to explain away the immaterial or reduce the immaterial to the material as their first epistemic instinct, even though the project continually resists the reduction (indeed, for example, no one to date has successfully or satisfactorily reduced mind to brain). In general contemporary empirical science proceeds according to methodological materialism and so do, for example, Functionalists in the Philosophy of Mind 6 I Thomas A. Spragens, Jr., The Politics of Motion (Lexington:University Press of Kentucky, 1973), p. 68. 1 Blackburn, The OxfordDictionary of Philosophy,op. cit., p. 236. Blackburn's definition of mechanism is the "belief that everything can be explained in ways modeled on 17`"-century conceptionsof scientificexplanation." Thinkers in the 1 7'h-centurysaw the universe as either one huge machine made up of a variety of inter-workingparts, or a set of machines interact- ing with one another. For a general discussion of the relationshipbetween materialism and mechanism during the early Modem endeavor, see the readings in Soul and Mind: Life and Thought in the SeventeenthCentury, ed. Daniel Garber. (Cambridge:Cambridge University Press, 1996). See Descartes, Principles of Philosophy, in The Philosophical Writingsof Descartes, trans. Cottingham, Stoothoff and Murdoch. (Cambridge: Cambridge University Press, 1984), vol. 1, pp. 202, 248-9 where he claims that a thinker should focus on efficient causes since "only God knows final causes." Also, see Bacon's Novum Organum, trans. Urbach and Gibson. (Chicago: Open Court Publishing, 1994), Bk. II, Aphorisms2-3, pp. 134- 5 where he claims that final causes are not applicableto anything but the will, and that focus- ing on such causes has been the source of "confusion" in the Ancient and Medieval periods. 5 For example, see Luddwig Feuerbach, The Essence of Christianity, trans. George Eliot. (New York: Harper, 1957); Patricia Churchland,"The Co-EvolutionaryResearch Ideology," in Readings in Philosophyand CognitiveScience, ed. Al Goldman. (Cambridge:MIT Press, 1993), pp. 745-59; Paul Churchland, Matter and Consciousness. (Cambridge: MIT Press, 1984). 6 See, for example, Daniel C. Dennett, ConsciousnessExplained. (Boston: Little, Brown and Company, 1991); Kosslyn and Koenig, WetMind: The New Cognitive Neuroscience.(New York:The Free Press, 1992). 4 .

  • Descartes' Influence in Shaping the Modern World-View
    R ené Descartes (1596-1650) is generally regarded as the “father of modern philosophy.” He stands as one of the most important figures in Western intellectual history. His work in mathematics and his writings on science proved to be foundational for further development in these fields. Our understanding of “scientific method” can be traced back to the work of Francis Bacon and to Descartes’ Discourse on Method. His groundbreaking approach to philosophy in his Meditations on First Philosophy determine the course of subsequent philosophy. The very problems with which much of modern philosophy has been primarily concerned arise only as a consequence of Descartes’thought. Descartes’ philosophy must be understood in the context of his times. The Medieval world was in the process of disintegration. The authoritarianism that had dominated the Medieval period was called into question by the rise of the Protestant revolt and advances in the development of science. Martin Luther’s emphasis that salvation was a matter of “faith” and not “works” undermined papal authority in asserting that each individual has a channel to God. The Copernican revolution undermined the authority of the Catholic Church in directly contradicting the established church doctrine of a geocentric universe. The rise of the sciences directly challenged the Church and seemed to put science and religion in opposition. A mathematician and scientist as well as a devout Catholic, Descartes was concerned primarily with establishing certain foundations for science and philosophy, and yet also with bridging the gap between the “new science” and religion. Descartes’ Influence in Shaping the Modern World-View 1) Descartes’ disbelief in authoritarianism: Descartes’ belief that all individuals possess the “natural light of reason,” the belief that each individual has the capacity for the discovery of truth, undermined Roman Catholic authoritarianism.

  • Quantum Logical Causality, Category Theory, and the Metaphysics of Alfred North Whitehead
    Quantum Logical Causality, Category Theory, and the Metaphysics of Alfred North Whitehead Connecting Zafiris’ Category Theoretic Models of Quantum Spacetime and the Logical-Causal Formalism of Quantum Relational Realism Workshop Venue: Swiss Federal Institute of Technology (ETH) Chair for Philosophy (building RAC) Raemistrasse 36, 8001 Zurich Switzerland January 29 – 30, 2010 I. Aims and Motivation Recent work in the natural sciences—most notably in the areas of theoretical physics and evolutionary biology—has demonstrated that the lines separating philosophy and science have all but vanished with respect to current explorations of ‘fundamental’ questions (e.g., string theory, multiverse cosmologies, complexity-emergence theories, the nature of mind, etc.). The centuries-old breakdown of ‘natural philosophy’ into the divorced partners ‘philosophy’ and ‘science,’ therefore, must be rigorously re- examined. To that end, much of today’s most groundbreaking scholarship in the natural sciences has begun to include explicit appeals to interdisciplinary collaboration among the fields of applied natural sciences, mathematics and philosophy. This workshop will be dedicated to the question of how a philosophical-metaphysical theory can be fruitfully applied to basic conceptualizations in the natural sciences. More narrowly, we will explore the process oriented metaphysical scheme developed by philosopher and mathematician Alfred North Whitehead (1861-1947) and Michael Epperson’s application of this scheme to recent work in quantum mechanics, and the relation of these to Elias Zafiris’s category theoretic model of quantum event structures. Our aim is to give participants from various fields of expertise (see list below) the opportunity to exchange their specialized knowledge in the context of a collaborative exploration of the fundamental questions raised by recent scholarship in physics and mathematics.

  • As Recursive Self-Prediction: Does a Deterministic Mechanism Reduce Responsibility?
    1 'Free Will' as Recursive Self-Prediction: Does a Deterministic Mechanism Reduce Responsibility? George Ainslie 11,09 To appear in Poland, Jeffrey and Graham, George, Addiction and Responsibility. MIT This material is the result of work supported with resources and the use of facilities at the Department of Veterans Affairs Medical Center, Coatesville, PA, USA. Advances in brain imaging have revealed more and more about the physical basis of motivated behavior, making the age-old dispute about free will and moral responsibility increasingly salient. Science seems to be delineating chains of causality for feelings, choices, and even beliefs; but if all mental life is strictly caused by prior events, and those by still earlier events in a chain extending back before birth, how can individuals be held responsible for their actions? Most people feel that they originate their actions (Nadelhoffer et.al., 2005) and will readily give opinions about whether particular circumstances make an action blameworthy or not (Monterosso et.al., 2005); but when philosophers take the chain of causality explicitly into account they generally distance themselves from these direct introspections, holding for instance that blame is just a way of assuaging instinctive resentment (Strawson, 1962/2003) or a threat to manipulate people’s motives (Dennett, 1984, pp. 131-172). I come to this subject with a behavioral science rather than a philosophy background, but the free will dispute looks to this outsider like something that recent empirical findings might resolve. The dispute is age old because of a fundamental conundrum. We insist on the truth of each of two propositions, the compatibility of which is far from obvious, perhaps absurd: 1.

While a few early chapters are historically organized, my goal in the historical chapters is to trace a developmental progression of thought that introduces basic philosophical methods and frames issues that remain relevant today. Later chapters are topically organized. These include philosophy of science and philosophy of mind, areas where philosophy has shown dramatic recent progress. This text concludes with four chapters on ethics, broadly construed. I cover traditional theories of right action in the third of these. Students are first invited first to think about what is good for themselves and their relationships in a chapter of love and happiness. Next a few meta-ethical issues are considered; namely, whether they are moral truths and if so what makes them so.

Wells All Rights Reserved INTRODUCTORY That there are many names in use amongst speculative men which do not always suggest to others determinant, particular ideas, or in truth anything at all, is what nobody will deny. – Berkeley Preface to the Fourth Edition The fourth edition of the Critical Glossary adds almost two hundred new technical terms for empirical social-natural sciences. These new social-natural sciences include education theory, economics, political science, social-natural sociology, psychology, organization and institution theory, management theory, mathematics and logic, deontological ethics, and justice theory. The edition covers new terminology development up through the publication of volume III of The Idea of Public Education, entitled The Institution of Public Education. Like the third edition, this edition consists of six main parts arranged in the following order: the Main Glossary, the Table of Realdefinitions of the Categories, the Critical Acroams and Principles, the Summary of the Transcendental Ideas, the Synopsis of the Momenta of Practical Judgment, and the Synopsis of the Momenta of Reflective Judgment.

  • Experience and Foundationalism in Audi's the Architecture of Reason
    Philosophy and Phenomenological Research Vol. LXVII, No. 1, July 2003 Experience and Foundationalism in Audi’s The Architecture of Reason WALTER SINNOTT-ARMSTRONG Dartmouth College Robert Audi’s The Architecture of Reason is a magnificent consolidation of decades of original work by a masterful philosopher. Its scope is impressive, as it covers both theoretical and practical reason in a slim volume. More impressive yet is its coherence, for Audi reveals a unified structure shared by what many philosophers assume to be disparate fields. In this short comment, I will focus on just a few aspects of Audi’s pri- mary analogies between theoretical and practical reason. He argues that “reason, conceived as a general human capacity, is, as Kant thought, unified. It is unified above all by its grounding, directly or through belief, in experi- ence, sensory, introspective, memorial, and reflective.” (233; cf. ix, 16, 80, 222) Audi’s structural thesis, then, is that good reasoning always has some foundation. His substantive thesis is that the foundation is always some experience. Hence his subtitle, “The Structure and Substance of Rationality”. 1 - Experience Audi admits “some differences between theoretical and practical reason”, but he claims that “none of them undermines the main analogies.” (193) It is not clear what it takes to undermine an analogy. Still, his main analogy regarding substance depends on a wide concept of experience, so his analogy seems problematic if his notion of experience is not adequately unified. One striking difference between the experiences that are said to ground theoretical reason and those said to ground practical reason concerns time.

  • Philosophy of Mind and the Problem of Free Will in the Light of Quantum Mechanics
    Philosophy of Mind and the Problem of Free Will in the Light of Quantum Mechanics. Henry P. Stapp Lawrence Berkeley National Laboratory University of California Berkeley, California 94720 Abstract Arguments pertaining to the mind-brain connection and to the physical effectiveness of our conscious choices have been presented in two recent books, one by John Searle, the other by Jaegwon Kim. These arguments are examined, and it is explained how the encountered difficulties arise from a defective understanding and application of a pertinent part of contemporary science, namely quantum mechanics. The principled quantum uncertainties entering at the microscopic levels of brain processing cannot be confined to the micro level, but percolate up to the macroscopic regime. To cope with the conflict between the resulting macroscopic indefiniteness and the definiteness of our conscious experiences, orthodox quantum mechanics introduces the idea of agent-generated probing actions, each of which specifies a definite set of alternative possible empirically/experientially distinguishable outcomes. Quantum theory then introduces the mathematical concept of randomness to describe the probabilities of the various alternative possible outcomes of the chosen probing action. But the agent-generated choice of which probing action to perform is not governed by any known law or rule, statistical or otherwise. This causal gap provides a logical opening, and indeed a logical need, for the entry into the dynamical structure of nature of a process that goes beyond the currently understood quantum mechanical statistical generalization of the deterministic laws of classical physics. The well-known quantum Zeno effect can then be exploited to provide a natural process that establishes a causal psychophysical link within the complex structure consisting of a stream of conscious experiences and certain macroscopic classical features of a quantum mechanically described brain.

  • Reasons, Practical Reason, and Practical Reasoning
    © Blackwell Publishing Ltd. 2004, 9600 Garsington Road, Oxford OX4 2DQ, UK and 350 Main Street, Malden, MA 02148, USA. Ratio (new series) XVII 2 June 2004 0034–0006 REASONS, PRACTICAL REASON, AND PRACTICAL REASONING Robert Audi Abstract The concepts of reasons as supporting elements, of practical reason as a capacity, and of practical reasoning as a process are central in the theory of action. This paper provides a brief account of each. Several kinds of reason for action are distinguished. Prac- tical reason is characterized both as a capacity whose exercise is largely constituted by a kind of responsiveness to reasons and as governed by certain normative principles; and practical reasoning is described as a kind of mental process in which reasons figure as premises and, from those premises, a practical conclusion is drawn. Much of the paper undertakes two related tasks: to distinguish the main kinds of practical reasoning and the associated criteria of assessment and to formulate some important substantive princi- ples of practical reason. These principles yield criteria of several sorts: logical, inferential, epistemic, and material. On the theory presented, although any (non-basic) intentional act can be grounded in practical reasoning, the same acts can be performed for the relevant reason(s) without being so grounded, and in either case their rationality depends on adequate support by the reason(s). One kind of reason is commonly thought to be captured by Kantian hypothetical imperatives. The final sections explore what constitutes a hypothetical imperative and what other princi- ples are needed to account for practical rationality. A major con- clusion is that in the domain of practical reason, if there are no categorical imperatives, there are no hypothetical imperatives either.
