For Diderot, the man who discovers significant truths not through the experimental method but through global intuition is a genius, a kind of visionary poet.

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early in his (...) life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the Ph.D. at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology. (shrink)

While Saint Augustine has been a household name for centuries, the same cannot be said of long-overlooked philosopher John Poinsot. But in _Augustine and Poinsot_, John Deely contends that the history of semiotics cannot be conceived of without Poinsot’s landmark contribution. According to Deely, even though Augustine was the first to describe _what_ the sign does, Poinsot was the first to show _how_ the sign mediates between nature and culture. This revolutionary volume demonstrates how Poinsot’s account of semiotics (...) allows us to produce human knowledge and experience. (shrink)

(A) I went to the pictures last Tuesday but I don’t believe that I did (1942, p. 543) or (B) I believe that he has gone out. But he has not (1944, p. 204) would be “absurd” (1942, p. 543; 1944, p. 204). Wittgenstein’s letters to Moore show that he was intensely interested in this discovery of a class of possibly true yet absurd assertions. Wittgenstein thought that the absurdity is important because it is “something similar to a contradiction, thought (...) it isn’t one” (1974, p. 177). What is the explanation of the absurdity of saying or believing something about myself that might be true? Wittgenstein thought that although the explanation will say “something about the logic of assertion” it will also show that “logic isn’t as simple as logicians think it is”. So although the explanation should.. (shrink)

One tradition of solving the surprise exam paradox, started by Robert Binkley and continued by Doris Olin, Roy Sorensen and Jelle Gerbrandy, construes surpriseepistemically and relies upon the oddity of propositions akin to G. E. Moore’s paradoxical ‘p and I don’t believe that p.’ Here I argue for an analysis that evolves from Olin’s. My analysis is different from hers or indeed any of those in the tradition because it explicitly recognizes that there are two distinct reductios at work in (...) the student’s paradoxical argument against the teacher. The weak reductio is easy to fault. Its invalidity determines the structure of the strong reductio, so-calledbecause it is more difficult to refute, but ultimately unsound because of reasons associated with Moore-paradoxicality. Previous commentators have not always appreciated this difference, with the result that the strong reductio is not addressed, or the response to the weak reductio is superfl uous. This is one reason why other analyses in the tradition are vulnerable to objections to which mine is not. (shrink)

This paper explores the modal interpretation of ?ukasiewicz's n -truth-values, his conditional and the puzzles they generate by exploring his suggestion that by ?necessity? he intends the concept used in traditional philosophy. Scalar adjectives form families with nested extensions over the left and right fields of an ordering relation described by an associated comparative adjective. Associated is a privative negation that reverses the ?rank? of a predicate within the field. If the scalar semantics is interpreted over a totally ordered domain (...) of cardinality n and metric ?, an n-valued Lukasiewicz algebra is definable. Privation is analysed in terms of non-scalar adjectives. Any Boolean algebra of 2 n ?properties? determines an n + 1 valued Lukasiewicz algebra. The Neoplatonic ?hierarchy of Being? is essentially the order presupposed by natural language modal scalars. ?ukasiewicz's ≈ is privative negation, and ? proves to stand for the extensional (antitonic) dual if ? then for scalar adjectives, especially modals. Relations to product logics and frequency interpretations of probability are sketched. (shrink)

Eventually and inevitably the study of a Roman comedy leads to the question of its relationship to the Greek model and to the nature of the original play. In recent years Terence's Adelphoe has stimulated numerous publications on the Menandrian comedy and on the changes which were made by the Latin dramatist. Greatest attention has been paid to the ending of the Greek play. This article, however, will examine the first two ‘acts’ of the Terentian comedy and will offer a (...) reconstruction of its primary model that differs from those that have been proposed in the major studies on this problem.

G. E. Moore famously observed that to say, “ I went to the pictures last Tuesday but I don’t believe that I did” would be “absurd”. Why should it be absurd of me to say something about myself that might be true of me? Moore suggested an answer to this, but as I will show, one that fails. Wittgenstein was greatly impressed by Moore’s discovery of a class of absurd but possibly true assertions because he saw that it illuminates “the (...) logic of assertion”. Wittgenstein suggests a promising relation of assertion to belief in terms of the idea that one “expresses belief” that is consistent with the spirit of Moore’s failed attempt to explain the absurdity. Wittgenstein also observes that “under unusual circumstances”, the sentence, “It’s raining but I don’t believe it” could be given “a clear sense”. Why does the absurdity disappear from speech in such cases? Wittgenstein further suggests that analogous absurdity may be found in terms of desire, rather than belief. In what follows I develop an account of Moorean absurdity that, with the exception of Wittgenstein’s last suggestion, is broadly consistent with both Moore’s approach and Wittgenstein’s. (shrink)

It is raining but you don’t believe that it is raining. Imagine accepting this claim. Then you are committed to saying ‘It is raining but I don’t believe that it is raining’. This would be an ‘absurd’ thing to claim or assert, yet what you say might be true. It might be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to assert something about yourself (...) that might be true of you? This is Moore’s paradox as it occurs in speech. What is the source of the absurdity? And why does it strike us that a contradiction is somehow at work when there is no contradiction in the content of what is asserted? In Section 2, I describe Moore’s formulation of the paradox and evaluate his own solutions. In Section 3, I discuss Wittgenstein’s inf luence in solving the paradox. In Section 4, I discuss Shoemaker’s priority thesis that once the absurdity in belief has been explained, then this will translate into an explanation of the absurdity in assertion. In Section 5, I discuss work on omissive and commissive Moore-paradoxical assertions, i.e. those of the forms p & I don’t believe that p and p & I believe that not-p. In Section 6, I discuss work on assertions of the form p & I don’t know that p. (shrink)

"In 1982, the author of this book issued a "promissory note" of just the sort that analytic philosophers of the twentieth century have led us to expect will come to nothing. This particular "note" occurred as a passing remark in the concluding chapter of his Introducing Semiotic (Indiana University Press) to the effect that it would be possible to establish the classical distinction between sense and intellect by means of the analysis of the role of relations in the action of (...) signs." "Provoked by the remark of a colleague that, could this promissory note be fulfilled, it would provide "the first essay worth reading on the subject since the days of Locke and Hume," Deely decided to break with the analytic tradition of leaving promissory notes unfulfilled and to develop the alleged possible proof in full." "A colloquium convened by Professor Norma Tasca, in the Fall of 1995 in Porto, Portugal, provided Deely with the occasion. His lengthy essay for the occasion, ponderously titled "The Intersemiosis of Perception and Understanding," became the initial draft of this book." "Especially in the circles of English-speaking philosophers, where a mere difference of degree between animal intelligence and human understanding has come to be largely taken for granted and philosophy has been reduced to a play of linguistic signs without regard for the dependency of those signs upon other signs whose play is far from linguistic, the work is bound to stimulate considerable debate."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

An analysis is proposed for the common argument that something should be preserved because it is irreplaceable. The argument is shown to depend on modal elements in irreplaceable, existence assumptions of preserve, and the logic of obligation. In terms of this theory it is argued that utilitarianism can account for most, but not all instances of persuasive appeals to irreplaceability. Beingessentially backwards looking, utilitarianism cannot in principle justify preservation of objects irreplaceable because of their history or genesis.

Using concepts from abstract algebra and type theory, I analyze the structural presuppositions of any holistic ethical theory. This study is motivated by such recent holistic theories in environmental ethics as Aldo Leopold’s land ethic, James E. Lovelock’s Gaia hypothesis, Arne Naess’ deep ecology, and various aesthetic ethics of the sublime. I also discuss the holistic and type theoretic assumptions of suchstandard ethical theories as hedonism, natural rights theory, utilitarianism, Rawls’ difference principle, and fascism. I argue that although there are (...) several common senses of part-whole in ethical theory, the central sense of holism in ethics is that of a theory that defines its key moral idea as an emergent group property grounded in the relational properties of its individual constituents. Hedonism and Kantianism do not count as holistic in this sense. Natural rights theory does in adegenerate way. Utilitarianism and various environmental ethics are paradigm examples. I point out as a general structural weakness of environmental holistic theories that their first-order grounding in nonmoral vocabulary seems to preclude an explanation of many moral intuitions about human ethics.

This book sets out for the first time in English and in the terms of modern logic the semantics of the Port Royal Logic of Antoine Arnauld and Pierre Nicole, perhaps the most influential logic book in the 17th and 18th centuries. Its goal is to explain how the Logic reworks the foundation of pre-Cartesian logic so as to make it compatible with Descartes' metaphysics. The Logic's authors forged a new theory of reference based on the medieval notion of objective (...) being, which is essentially the modern notion of intentional content. Indeed, the book's central aim is to detail how the Logic reoriented semantics so that it centered on the notion of intentional content. This content, which the Logic calls comprehension, consists of an idea's defining modes. Mechanisms are defined in terms of comprehension that rework earlier explanations of central notions like conceptual inclusion, signification, abstraction, idea restriction, sensation, and most importantly within the Logic's metatheory, the concept of idea-extension, which is a new technical concept coined by the Logic. Although Descartes is famous for rejecting "Aristotelianism," he says virtually nothing about technical concepts in logic. His followers fill the gap. By putting to use the doctrine of objective being, which had been a relatively minor part of medieval logic, they preserve more central semantic doctrines, especially a correspondence theory of truth. A recurring theme of the book is the degree to which the Logic hews to medieval theory. This interpretation is at odds with what has become a standard reading among French scholars according to which this 16th-century work should be understood as rejecting earlier logic along with Aristotelian metaphysics, and as putting in its place structures more like those of 19th-century class theory.

There is an almost overwhelming mass of material available to the scholar who wishes to investigate the history of the text of Terence's plays. The manuscripts themselves number over 450 and of these over 100 belong to the period 800-c. 1300. No one, however, has undertaken a comprehensive recension of even the older group of medieval manuscripts. One reason for this is that the extent to which contamination has occurred makes classification extremely difficult, another is that it is unlikely that (...) the laborious task of examining and studying so many manuscripts will produce much new evidence for the text itself. Many of the corruptions which survive in the plays probably arose at an early stage in the tradition and prior to the archetype of the manuscripts which have been used by past editors. Any marked advance in the constitution of the text would seem to depend on the discovery of a manuscript which belonged to a different tradition. (shrink)

In his “Reply to Williams” (2013), a response to my “David-Hillel Ruben’s ‘Traditions and True Successors’: A Critical Reply.” (2013), David Ruben reports that there is much that we disagree about concerning the nature of true succession. I am not entirely persuaded by what he says of these disagreements.

A universal Horn sentence in the language of polynomial-time computable combinatorial functions of natural numbers is true for the natural numbers if, and only if, it is true for PETs of p-time p-isolated sets with functions induced by fully p-time combinatorial operators.

An interpretation in modal and tense logic is proposed for Boethius's reconciliation of God's foreknowledge with human freedom from The consolation of philosophy, Book V. The interpretation incorporates a suggestion by Paul Spade that God's special status in time be explained as a restriction of God's knowledge to eternal sentences. The argument proves valid, and the seeming restriction on omnipotence is mitigated by the very strong expressive power of eternal sentences.

The paper is a study of the logic of existence, negation, and order in the Neoplatonic tradition. The central idea is that Neoplatonists assume a logic in which the existence predicate is a comparative adjective and in which monadic predicates function as scalar adjectives that nest the background order. Various scalar predicate negations are then identifiable with various Neoplatonic negations, including a privative negation appropriate for the lower orders of reality and a hyper-negation appropriate for the higher. Reversion to the (...) One can then be explained as the logical inference of hyper-negations from mundane knowledge. Part I develops the relevant linguistic and logical theory, and Part II defends Wolfson and the scalar interpretation against the more traditional Aristotelian understanding of Whittaker and others of reversion as intensional abstraction.

The paper shows that in the Art of Thinking (The Port Royal Logic) Arnauld and Nicole introduce a new way to state the truth-conditions for categorical propositions. The definition uses two new ideas: the notion of distributive or, as they call it, universal term, which they abstract from distributive supposition in medieval logic, and their own version of what is now called a conservative quantifier in general quantification theory. Contrary to the interpretation of Jean-Claude Parienté and others, the truth-conditions do (...) not require the introduction of a new concept of ‘indefinite’ term restriction because the notion of conservative quantifier is formulated in terms of the standard notion of term intersection. The discussion shows the following. Distributive supposition could not be used in an analysis of truth because it is explained in terms of entailment, and entailment in terms of truth. By abstracting from semantic identities that underlie distribution, the new concept of distributive term is definitionally prior to truth and can, therefore, be used in a non-circular way to state truth-conditions. Using only standard restriction, the Logic’s truth-conditions for the categorical propositions are stated solely in terms of (1) universal (distributive) term, (2) conservative quantifier, and (3) affirmative and negative proposition. It is explained why the Cartesian notion of extension as a set of ideas is in this context equivalent to medieval and modern notions of extension. (shrink)

I argue that ‘Moore’s paradox for God’. I do not believe this proposition shows that nobody can be both omniscient and rational in all her beliefs. I then anticipate and rebut three objections to my argument.

Studies of testosterone's effect on dominance are confounded by the effects of dominance experiences on testosterone. Furthermore, antisocial behavior tends to originate prepubertally, when testosterone levels are the same for aggressive males, nonaggressive males, and females. It seems more parsimonious to view variation in testosterone as an effect of dominance-related mood states than to invoke a reciprocal model.
