A set A is symmetric enumeration (se-) reducible to a set B (A ≤\sb se B) if A is enumeration reducible to B and \barA is enumeration reducible to \barB. This reducibility gives rise to a degree structure (D\sb se) whose least element is the class of computable sets. We give a classification of ≤\sb se in terms of other standard reducibilities and we show that the natural embedding of the Turing degrees (D\sb T) into the enumeration degrees (D\sb e) (...) translates to an embedding (ι\sb se) into D\sb se that preserves least element, suprema, and infima. We define a weak and a strong jump and we observe that ι\sb se preserves the jump operator relative to the latter definition. We prove various (global) results concerning branching, exact pairs, minimal covers, and diamond embeddings in D\sb se. We show that certain classes of se-degrees are first-order definable, in particular, the classes of semirecursive, Σ\sb n ⋃ Π\sb n, Δ\sb n (for any n \in ω), and embedded Turing degrees. This last result allows us to conclude that the theory of D\sb se has the same 1-degree as the theory of Second-Order Arithmetic. (shrink)

We investigate and extend the notion of a good approximation with respect to the enumeration ${({\mathcal D}_{\rm e})}$ and singleton ${({\mathcal D}_{\rm s})}$ degrees. We refine two results by Griffith, on the inversion of the jump of sets with a good approximation, and we consider the relation between the double jump and index sets, in the context of enumeration reducibility. We study partial order embeddings ${\iota_s}$ and ${\hat{\iota}_s}$ of, respectively, ${{\mathcal D}_{\rm e}}$ and ${{\mathcal D}_{\rm T}}$ (the Turing degrees) into (...) ${{\mathcal D}_{\rm s}}$ , and we show that the image of ${{\mathcal D}_{\rm T}}$ under ${\hat{\iota}_s}$ is precisely the class of retraceable singleton degrees. We define the notion of a good enumeration, or singleton, degree to be the property of containing the set of good stages of some good approximation, and we show that ${\iota_s}$ preserves the latter, as also other naturally arising properties such as that of totality or of being ${\Gamma^0_n}$ , for ${\Gamma \in \{\Sigma,\Pi,\Delta\}}$ and n > 0. We prove that the good enumeration and singleton degrees are immune and that the good ${\Sigma^0_2}$ singleton degrees are hyperimmune. Finally we show that, for singleton degrees a s < b s such that b s is good, any countable partial order can be embedded in the interval (a s, b s). (shrink)

We prove that for every ${\mathrm{\Sigma }}_{2}^{0}$ enumeration degree b there exists a noncuppable ${\mathrm{\Sigma }}_{2}^{0}$ degree a > 0 e such that b′ ≤ e a′ and a″ ≤ e b″. This allows us to deduce, from results on the high/low jump hierarchy in the local Turing degrees and the jump preserving properties of the standard embedding l: D T → D e , that there exist ${\mathrm{\Sigma }}_{2}^{0}$ noncuppable enumeration degrees at every possible—i.e., above low₁—level of the high/low (...) jump hierarchy in the context of D e.

Defining a class of sets to be uniform Δ02 if it is derived from a binary {0,1}{0,1}-valued function f≤TKf≤TK, we show that, for any C⊆DeC⊆De induced by such a class, there exists a high Δ02 degree c which is incomparable with every degree b ϵ Ce \ {0e, 0'e}. We show how this result can be applied to quite general subclasses of the Ershov Hierarchy and we also prove, as a direct corollary, that every nonzero low degree caps with both (...) a high and a nonzero low Δ02 degree.

We discuss a notion of forcing that characterizes enumeration 1-genericity, and we investigate the immunity, lowness, and quasiminimality properties of enumeration 1-generic sets and their degrees. We construct an enumeration operator Δ such that, for any A, the set ΔA is enumeration 1-generic and has the same jump complexity as A. We deduce from this and other recent results from the literature that not only does every degree a bound an enumeration 1-generic degree b such that a'=b', but also that, (...) if a is nonzero, then we can find such b satisfying 0eshrink)

Scepticisme, Clandestinité et Libre Pensée. Paris: Honoré Champion, 2002. Pp. 382. Cloth, €60.00. This book consists of papers from two Tables rondes held in Dublin in 1999 on the occasion of the Tenth International Congress on the Enlightenment. The contributors are: Paganini, Benítez, Dybikowski, Alan Charles Kors, (...) Winfried Schröder, José R. Maia Neto, Adam Sutcliffe, Justin Champion, Antony McKenna, Lorenzo Bianchi, Christine Berkvens-Stevelinck, Pierre Lurbe, Stephen David Snobelen, Nigel Aston, and Stuart Brown. There is remarkably little overlap among the papers and Paganini has clearly insisted on very [End Page 561] high standards. Because of space limitations, I shall focus on several of the general themes which run through the book rather than on individual contributions.Despite the phenomenal success Richard Popkin and collaborators like the late Charles B. Schmitt, Giorgio Tonelli, and Ezequiel de Olaso have had in documenting the amazing impact of skepticism in the Renaissance and in the years up to the Enlightenment, this volume demonstrates that skepticism, that many-faceted force, continued throughout the eighteenth-century Enlightenment. After Bayle, and the application of his special forms of skepticism to theological topics—forms which were often employed, contrary to Bayle's probable intentions, in defense of atheism—skepticism went "underground." A large variety of literature was circulated in manuscript form, the clandestine literature of the period. The lesson which this conference celebrates is that skepticism did not cease being a major cultural force. Thus there is, thanks to the philosophical dimension of the clandestine literature in the eighteenth century, a transition from Christian rationalism to an anti-Christian rationalism.Major figures of the Enlightenment were, of course, well-acquainted with skepticism, e.g., Berkeley, Voltaire, Hume, Crousaz, Condillac, Reid, and Kant. Not surprisingly, the major topics discussed in these papers center around skepticism, fideism and atheism, proofs for the existence of God, and the status of the "preambles" to the faith. These all receive careful attention. The tension between the arguments for Christian Pyrrhonism versus anti-Christian rationalism runs through many of these papers. And of course Bayle's points of view on both sides of the Christian debate appear in much of the clandestine literature. The matter of the immortality of the soul is carefully discussed. What is the status of this doctrine? Is it a question of Church dogma or is it another belief to be discarded in the light of reason?The connection perceived to hold between atheism and political legitimacy are explored in several papers. In the seventeenth century, Locke would exclude atheists from the body politic, in part because they were unable to truthfully swear an oath. Atheists were perceived as a danger for many eighteenth-century figures and the political need to suppress atheism was widely understood and accepted by those in the various religious establishments. Bayle's two-century-old attempt to break the putative logical tie between morality and religion failed in his own day, and despite the efforts of the authors of clandestine philosophical literature, the intimate link Bayle tried to break seems to be stronger than ever in much of the world today. It is interesting that the United States is virtually the only industrial and democratic society in which atheists are virtually precluded from being political candidates in federal, and probably most local, elections. Among other things, the papers in this volume help one to understand just how difficult breaking free from theological constraints in the interest of political freedom has proved to be.

This volume brings together for the first time some of the most helpful and insightful essays on the four most influential and discussed philosophers in the history of existentialism: Kierkegaard, Nietzsche, Heidegger, and Sartre.

"....an admirably clear account of Heidegger's relation to the philosophical tradition, and especially of his criticism of Cartesianism." -- Richard Rorty, University of Virginia.

Current views of the control of complex, purposeful movements acknowledge that organizational processes must reconcile multiple concerns. The central priority is of course accomplishing the actor's goal. But in specifying the manner in which this occurs, the action plan must accommodate such factors as the interaction of mechanical forces associated with the motion of a multilinked system (classical mechanics) and, in many cases, intrinsic bias toward preferred movement patterns, characterized by so‐called “coordination dynamics.” The most familiar example of the latter (...) is the symmetry constraint, where spatial trajectories and/or temporal landmarks (e.g., reversal points) of concurrentlymoving body segments (limbs, digits, etc.) exhibit mutual attraction. The natural coordination tendencies that emerge through these constraints can facilitate or hinder motor control, depending on the degree of congruency with the desired movement pattern. Motor control theorists have long recognized the role of classical mechanics in theories of movement organization, but an appreciation of the importance of intrinsic interlimb bias has been gained only recently.Although detailed descriptions of temporal coordination dynamics have been provided, systematic attempts to identify additional salient dimensions of interlimb constraint have been lacking. We develop and implement here a novel method for examining this problem by exploiting two robust principles of psychomotor behavior, the symmetry constraint and the Two‐Thirds Power Law. Empirical evidence is provided that the relative spatial patterns of concurrently moving limbs are naturally constrained in much the same manner as previously identified temporal constraints and, further, that apparent velocity interference is an indirect, secondary consequence of primary spatial assimilation. The theoretical implications of spatial interference are elaborated with respect to movement organization and motor learning. The need to carefully consider the appropriate dimensions with which to characterize coordination dynamics is also discussed. (shrink)

The psychiatrist, Dr. Charles B. Nemeroff of Emory University, is the most prominent example to date in a series of disclosures that is shaking the world of academic medicine and seems likely to force broad changes in the relationships between doctors and drug makers.

As originally planned this volume was meant to cover a somewhat wider scope than, in fact, it has turned out to do. When, in rg68, I initially conceived of preparing it, it was proposed to deal with several aspects of early modern scepticism, in addition to the fortuna of the Academica, and to publish various loosely related pieces under the title of 'Studies in the History of Early Modern Scepticism. ' Thereby, I foresaw that I would exhaust my knowledge of (...) the subject and would then be able to turn my attention to other matters. In initiating my research on this topic, however, I soon found that there remained a much greater bulk of material to study than could possibly be dealt with between the covers of the single modest volume which I envisioned. My proposed section on Cicero's Academica was to cover between 50 and 75 pages in the original plan. It soon became apparent, however, especially after Joannes Rosa's hitherto unstudied commentary on Cicero's work was uncovered, that this material would have to be treated at a much greater length than I had foreseen. The present volume is the result of this expanded investigation. The monograph which has come from this alteration in plans has, I think, the virtues of continuity and cohesive ness and one hopes that these advantages offset the benefits of a broader scope which were sacrificed.

Although the application of the emulation model to the control of simple positioning movements is relatively straightforward, extending the scheme to actions requiring multisegmental, interlimb coordination complicates matters a bit. Special consideration of the demands in this case, both on sensory processing and on the process model (two key elements of the Kalman filter), are discussed.

During the past few decades, engineering ethics has been oriented towards protecting the public from professional misconduct by engineers and from the harmful effects of technology. This “preventive ethics” project has been accomplished primarily by means of the promulgation of negative rules. However, some aspects of engineering professionalism, such as (1) sensitivity to risk (2) awareness of the social context of technology, (3) respect for nature, and (4) commitment to the public good, cannot be adequately accounted for in terms of (...) rules, certainly not negative rules. Virtue ethics is a more appropriate vehicle for expressing these aspects of engineering professionalism. Some of the unique features of virtue ethics are the greater place it gives for discretion and judgment and also for inner motivation and commitment. Four of the many professional virtues that are important for engineers correspond to the four aspects of engineering professionalism listed above. Finally, the importance of the humanities and social sciences in promoting these virtues suggests that these disciplines are crucial in the professional education of engineers. (shrink)

Martin Heidegger is now widely recognized as one of the greatest philosophers of the twentieth century. He transformed mainstream philosophy by defining its central task as asking the 'question of being'. His thought has contributed to the turn to hermeneutics and to postmodernism and poststructuralism. Moreover, the disclosure of his deep involvement in Nazism has provoked much debate about the relation of philosophy to politics. This edition brings to the fore other works, as well as alternative approaches to scholarship. The (...) essays cover topics such as Heidegger's conception of phenomenology, his relation to Kant and Husserl, his account of truth, and his stand on the realism/anti-realism debate. This edition includes a new preface by the editor, revised versions of several essays from the first edition, and an exhaustive bibliography, providing guidance for both newcomers to Heidegger's work and established scholars.

In this essay I renew the case for Conditional Excluded Middle in light of recent developments in the semantics of the subjunctive conditional. I argue that Michael Tooley's recent backward causation counterexample to the Stalnaker-Lewis comparative world similarity semantics undermines the strongest argument against CXM, and I offer a new, principled argument for the validity of CXM that is in no way undermined by Tooley's counterexample. Finally, I formulate a simple semantics for the subjunctive conditional that is consistent with both (...) CXM and Tooley's counterexample. (shrink)

In ‘Syntactical Treatments of Modality, with Corollaries on Reflexion Principles and Finite Axiomatizability’, Acta Philosophica Fennica16 (1963), 153–167, Richard Montague shows that the use of a single syntactic predicate (with a context-independent semantic value) to represent modalities of alethic necessity and idealized knowledge leads to inconsistency. In ‘A Note on Syntactical Treatments of Modality’, Synthese44 (1980), 391–395, Richmond Thomason obtains a similar impossibility result for idealized belief: under a syntactical treatment of belief, the assumption that idealized belief is deductively closed, (...) together with certain other plausible conditions on idealized belief, imply that an ideal believer with consistent beliefs cannot believe the truth of Robinson's Arithmetic. In this essay I show that an impossibility result similar to Thomason's can be obtained which does not assume that belief is deductively closed or ideal in any other way. (shrink)

This paper examines the characteristics of infectious diseases that raise special medical and social ethical issues, and explores ways of integrating both current bioethical and classical public health ethics concerns. Many of the ethical issues raised by infectious diseases are related to these diseases’ powerful ability to engender fear in individuals and panic in populations. We address the association of some infectious diseases with high morbidity and mortality rates, the sense that infectious diseases are caused by invasion or attack on (...) humans by foreign micro‐organisms, the acute onset and rapid course of many infectious diseases, and, in particular, the communicability of infectious diseases. The individual fear and community panic associated with infectious diseases often leads to rapid, emotionally driven decision making about public health policies needed to protect the community that may be in conflict with current bioethical principles regarding the care of individual patients. The discussion includes recent examples where dialogue between public health practitioners and medical‐ethicists has helped resolve ethical issues that require us to consider the infected patient as both a victim with individual needs and rights and as a potential vector of disease that is of concern to the community.

The origins of this book go back to I956 when it was suggested to me that a study on the philosophy of Gianfrancesco Pico della Mirandola would furnish an important addition to our knowledge of the philoso phy of the Italian Renaissance. It was not, however, until I960 that I could devote a significant portion of my time to a realization of this goal. My work was essentially completed in 1963, at which time it was presented in its original form (...) as a doctoral dissertation in the Phi losophy Department of Columbia University. Since then I have made many minor improvements and several chapters have been extensively reworked. This study represents the first attempt in fifty years to give a detailed account of even a portion of Gianfrancesco Pico's life and thought. The most comprehensive previous study, Gertrude Bramlette Richards, "Gianfrancesco Pico della lv1irandola" (Cornell University Dissertation, I 9 I 5), which I have found very useful in preparing my own book, is largely based on secondary literature and is mistaken in a number of details. Furthermore, Miss Richards' treatment of Gian francesco Pico as a thinker is very sketchy and is not an exhaustive study of his own writings. It is hoped that my present study, built in part on her extensive bibliographical indications, brings forth a certain amount of new information which will be of value for further research. (shrink)

Martin Heidegger is now widely recognised alongside Wittgenstein as one of the greatest philosophers of the twentieth century. He redefined the central task of philosophy as the investigation of the nature of being, and has exerted a profound impact on literary theory, theology, psychotherapy, political theory, aesthetics, environmental studies, as well as mainstream philosophy. His thought has contributed to the recent turn to hermeneutics in philosophy and the social sciences, and to current post-modern and post-structuralist developments. The disclosing of his (...) deep involvement in the ideology of Nazism has provoked much debate about the relation of philosophy to politics. This volume contains both overviews of Heidegger's life and works and analysis of his most important work, Being and Time. In addition there are discussions of Heidegger's thought in relation to mysticism, traditional theology, ecology, psychotherapy and the philosophy of language. The volume also contains the first in-depth study of what has been called Heidegger's second greatest work, the Beitrage zur Philosophie. (shrink)

IN his recent book on Heidegger's concept of authenticity, Eclipse of the Self, Michael Zimmerman points out Heidegger's life-long attempt to link the theoretical-ontological questions of traditional philosophy with the personal-existential issues of everyday life. The aim of grounding the "question of Being" in a deeper, more authentic way of being human is most strikingly evident in Being and Time. There the seemingly most abstract of all metaphysical questions--What is the meaning of Being?--is posed in terms of the most intensely (...) personal question facing any individual--What is the meaning of human existence? To answer the former question appropriately, Heidegger claims, we must transform our approach to the latter. And this in turn requires a radical alteration in the quality of our lives. Despite Heidegger's insistence that his ontological findings have no evaluative import, the exhortative tone of the account of authenticity is unmistakable. He quotes with full approval Count Yorck's description of his own philosophy: "The practical aim of our standpoint is pedagogical in the broadest sense of the word". Its goal is "to make possible the cultivation of individuality". Emerging out of an age that perceived itself as a time of profound crisis, a period shaken by intellectual currents of relativism, scientific materialism, Darwinism, and the complete secularization of life, Being and Time attempts to combat the "groundlessness" of the contemporary world by uncovering enduring values and meanings within the framework of "worldliness" and human finitude. The "question of Being" is no exercise in arcane speculation; its aim is to restore a sense of the gravity and responsibility of existence by recovering a more profound grasp of what it is to be.

Transactive memory theory describes the processes by which benefits for memory can occur when remembering is shared in dyads or groups. In contrast, cognitive psychology experiments demonstrate that social influences on memory disrupt and inhibit individual recall. However, most research in cognitive psychology has focused on groups of strangers recalling relatively meaningless stimuli. In the current study, we examined social influences on memory in groups with a shared history, who were recalling a range of stimuli, from word lists to personal, (...) shared memories. We focused in detail on the products and processes of remembering during in-depth interviews with 12 older married couples. These interviews consisted of three recall tasks: (1) word list recall; (2) personal list recall, where stimuli were relevant to the couples’ shared past; and (3) an open-ended autobiographical interview. We conducted these tasks individually and then collaboratively two weeks later. Across each of the tasks, although some couples demonstrated collaborative inhibition, others demonstrated collaborative facilitation. We identified a number of factors that predicted collaborative success, in particular, group-level strategy use. Our results show that collaboration may help or hinder memory, and certain interactions are more likely to produce collaborative benefits. (shrink)

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive complementarity argument, (...) say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

Stone & Wang collate the nascent research examining the mnemonic consequences associated with social media use. In particular, they highlight two important factors in understanding how social media use shapes the way individuals and groups remember the past: the type of information (personal vs. public) and the role (producer vs. consumer) individuals undertake when engaging with social media. Stone and Wang investigate those two features in relation to induced forgetting for personal information and false memories/truthiness for public information.

A selection function based semantics is offered for the 'can' of ability based on the idea that 'John can run a four minute mile' is true iff John would do so under the right conditions, meaning that he would do so under at least one appropriately chosen test condition. Completeness is proved for an axiom system and semantics based on this idea, and the logic turns out to be interestingly different from any standard system of modal logic.

In Practical Ethics Peter Singer argues for an ‘obligation to assist’: First premise: If we can prevent something bad without sacrificing anything of comparable significance, we ought to do it. Second premise: Absolute poverty is bad. Third premise: There is some absolute poverty we can prevent without sacrificing anything of comparable moral significance. Conclusion: We ought to prevent some absolute poverty. This paper is dedicated to a criticism of four readings of the first premise and an undesirable link the first (...) premise has with the third. The paper ends by offering a alternative formulation of an ‘obligation to assist,’ which suffers from none of these problems. (shrink)

In this essay I present a new version of the Paradox of the Knower and show that this new paradox vitiates a certain argument against epistemic closure. I then prove a theorem that relates the new paradox to epistemological scepticism. I conclude by assessing the use of the Knower in arguments against syntactical treatments of knowledge.

In a 1994 ANALYSIS article Peter Klein and Ted Warfield show that an epistemically more coherent set of beliefs often has a smaller unconditional probability of joint truth than some of its less coherent subsets. They conclude that epistemic justification, as understood in one version of a coherence theory of justification, is not truth conducive. After getting clear about what truth conduciveness requires, I show that their argument does not tell against BonJour's coherence theory.

John Case , the most important English Aristotelian of the Renaissance period, has not yet received the attention he deserves. In his Lapis philosophicus , an exposition of Aristotle's Physics, is found a discussion of the relation of nature to art which parallels in many ways that formulated a few years later in the writings of Francis Bacon. Case argues, in a way more reminiscent of the works of Giambattista della Porta than of those of Aristotle, that the natural philosopher (...) can legitimately apply the productive arts in helping nature to fulfill her function. Moreover, while rejecting the excessive claims of the Paracelsians, Case does accept the transmutational claims of the alchemists. In the final analysis, his ‘Aristotelianism’ has been tempered by the tradition of Renaissance natural magic. Like many other Peripatetic thinkers of the period, Case shows himself to be an eclectic, drawing materials from a wide variety of sources and open to many of the new scientific tendencies then developing.

In The Scientific Image B. C. van Fraassen argues that a theory of explanation ought to take the form of a theory of why-questions, and a theory of this form is what he provides. Van Fraassen's account of explanation is good, as far as it goes. In particular, van Fraassen's theory of why-questions adds considerable illumination to the problem of alternative explanations in psychodynamics. But van Fraassen's theory is incomplete because it ignores those classes of explanations that are answers not (...) to why-questions but to how-questions. In this article I provide a unified theory of explanatory questions that comprehends both how-questions and why-questions, and I show that a question-theoretic approach to explanation can be defended independently of van Fraassen's programme of Constructive Empiricism.

They measure approximately 10 X 14 cm. and each contains about 600fois. At the beginning of Vol. I, in a later hand (19th century?), we read: "Nicolas de la Thoison, baron de Bussy, qui 6crivit ces m6moires, 6tait conseiller laic au Parlement de Bourgogne. Il fur pourru par la r6signation de Pierre Catherine le IV Ddcembre M.DC.XLV et regu le XXIX janvier M.DC.XLVI.

There is also a drawing of the coat-of-arms which has been described. That the de la Toison coat-of-arms is a quintefeuille is verified by Theodore de Renesse, Dictionnaire des figures h$raldiques (Brussels, 1894-1903) III, 461. The passage cited above from the manuscript is directly quoted from Pierre Paillot, Le Parlement de Bouroongne [I], son origins, son $tablissemerit, et son progr~s (Dijon, 1649), p. 326. s A description of this manuscript will be found in the Appendix. 70 HISTORY OF PHILOSOPHY shall here only give a preliminary survey of this third manuscript, pointing out some of the more interesting features and mentioning some problems connected with it which should be investigated further in more detail. As is now well-known the writings of Sextus Empiricus, which form the major extant compendium of ancient skeptical philosophy, had quite a significant impact on sixteenth and seventeenth-eentury thought, after their reintroduction in the sixteenth century. ~ Sextus' works were available in printed Latin editions after 15695 and the Greek text was printed in...

In lieu of an abstract, here is a brief excerpt of the content:Giulio Castellani (1528-1586): A Sixteenth-Century Opponent of Scepticism CHARLES B. SCH1VHTT THE PROBLEMOF THE ORIGINS of scepticism in early modern philosophy has been a much debated issue. Sanches, Montaigne, Charron, and Bayle all contributed to the milieu which made it possible for the sceptical direction of thought to develop into such a potent force by the time of David Hume. The actual origins of modern scepticism, which seem (...) to go back to a slightly earlier date, lie in the confluence of several different intellectual movements during the early years of the sixteenth century: Christian anti-intellectualism, the reintroduction of the literary remains of the ancient sceptical tradition, the epistemological developments of scholastic nominalism, and certain inherent tendencies of Renaissance humanism. It is in the early decades of the sixteenth century that the seeds which later blossomed forth at the time of Hume originally took root. Hume himself merely reaped the harvest of several hundred years of sceptical preparation? Aside from certain manifestations of doubt which developed out of the epistemological theories of fourteenth-century nominalism, the origins of modern scepticism are generally held to date from the first publication of Sextus Empiricus' ancient summaries of Pyrrhonism during the decade of the 1560's. While it has previously been recognized that at least hints of scepticism were current in the fifteenth and early sixteenth centuries, the implications to be derived from this fact do not seem to have been adequately exploredT I shall not here go into these early manifestations of scepticism in a detailed way. Rather, I shall briefly touch upon a few little-known examples of the influence of ancient scepticism during the Reniassance and, then, I shall focus upon an early and practically neglected attack upon scepticism published before the first printings of Sextus Empiricus' writings. I shall discuss the circumstances of the composition of Giulio Castellani's anti-sceptical work, Adversus Marci TuIlii Ciceronis academicas questiones disi For a recent survey of early modem scepticism see Richard H. Popkin, The History o] Scepticism /tom Erasmus to Descartes (Assen: 1960). Of the large literature which connects scepticism with religious doubt during this period see especially Henri Busson, Les sources et le dgveloppement du rati~nalizme dar~ la litt~rature ]ran~aise de la Renaissance (Paris: 1957) and Don Cameron Allen, Doubt's Boundless Sea (Baltimore: 1964). The di.~cussionof this period seems to be the weakest part of Popkin's excellent book, particularly with regard to the treatment which he gives to Italian thought. See, also, his other articles, especially,"Skepticismand the Counter-Reformation in France," Archiv/fir Re/armationsgeschichte, LI (1960),58-86and "The High Road to Pyrrhonism," American Philosophical Quarterly, II (1965),18--32.In my forthcoming study, Gian]rancesco Pico (1469-1533) and His Critique o/Aristotle, I give a detailed analysis of the major representative of early sixteenthcentury scepticism. [151 16 HISTORY OF PHILOSOPHY putatio (1558), which antedates the first printing of Sextus Empiricus by four years, indicating that scepticism was already widespread enough to provoke an attack from the camp of the dogmatists. Furthermore, I shall analyze Castellani 's arguments in the context of the philosophical views of the mid-sixteenth century. Scepticism in the Early Renaissance Direct knowledge of the major ancient source of scepticism, the already mentioned writings of Sextus Empiricus, was rare throughout the Middle Ages. There are but two known extant Latin manuscripts which date before 1400. s From the fifteenth century we know of two more manuscripts, neither complete in itself, but together containing a significant portion of the extant writings of Sextus. 4 This evidence indicates that Sextus' works were not well known in translation before the first Latin editions of The Oulines o] Pyrrhonism (1562) and of Against the Mathematicians (1569). With the advent of an increased interest in and knowledge of Greek in Western Europe in the fifteenth century, we find a corresponding increase in the number of Greek manuscripts of Sextus Empiricus. Consequently, by the time of the first printings, an appreciable number of copies of his writings were available. Some were brought from the East, but a large number also are attributable to European scribes. 5 We also know that in... (shrink)
