Ever since the Proslogion was first circulated , critics have been bemused by St Anselm's brazen attempt to establish a matter of fact, namely, God's existence, from the simple analysis of a term or concept. Yet every critic who has proposed to ‘write the obituary’ of the Ontological Argument has found it to be remarkably resilient . At the risk of adding to a record of failures, I want to venture a new method for attacking this durable argument. Neither the (...) common version of Anselm's argument from Chapter II of the Proslogion nor the previously unrecognized modal version uncovered by Norman Malcolm from Pros , III can possibly get under way without Anselm's celebrated assertion that God is that than which no greater can be conceived.

According to david lewis, When the conditional excluded middle is accepted for would-Asserting counterfactuals, It becomes difficult or impossible to define their might-Asserting counterparts. But I provide a definition of "might" counterfactuals that does agree with cem: a "might" counterfactual is true iff its consequent is true at some antecedent-World within a set whose membership is determined by appeal to various categories of possibility.

Ruth Millikan and others adopt a normative definition of biological functions that is heavily used in areas such as Millikan’s teleosemantics, and also for emerging efforts to naturalize other areas of philosophy. I propose an experiment called the Lapse Test to determine exactly what form of normativity, if any, truly applies to biological functions. Millikan has not gone far enough in playing down as “impersonal” or “quasi” the precise mode of normativity that she attributes to biological functions. Further, her mode (...) fails to qualify as genuine normativity at all, lacking an essential feature: some lapse of responsibility on the part of any entity or system that is charged with failing to do as it is “supposed.” Nor, as we will see, is there anything in English idioms used to describe biological functions that can provide a persuasive argument to rehabilitate Millikan’s normative definition.

In lieu of an abstract, here is a brief excerpt of the content:An Intervention into the Flew/Fogelin Debate Kenneth G. Ferguson Under an aggressive title, Robert FogeUn has recently undertaken to reveal "What Hume Actually Said About Miracles."1 He felt this necessary to correct whathe considers a serious misreading ofHume's essay "OfMiracles" (sec. 10 ofthe Enquiries2), a reading which infers that Hume did not argue thatmiracles are impossible a priori (Fogelin, 81). One writer at least regards this reading so (...) common that she has dubbed it the "traditional interpretation" of Hume's account of miracles.3 At any rate, it finds a strong advocate in Anthony Flew,4 against whom the majority ofFogelin's comments are directed. What I find fascinating about this debate is that both Flew and FogeUn appear to be right. On the one hand, Hume does have the textual resources to marshall a fully deductive argument against miracles, at least, once a strict definition of miracles is admitted. On the other hand, while exploiting these resources, Hume somewhat clumsily mingles in vestiges ofa not-fully consistent inductive argument against miracles which he bases on the balancing of probabilities. I will attempt to identify these two skeins ofargument, in the anticipation that this will help to temper the debate between Flew and Fogelin. Hume opens section 10by promisingan argument that will furnish "an everlasting check to all kinds of superstitious delusion" (E 110). Moreover, he claims that "there is here a direct and full proof... against the existence of any miracle" (E 115), a quote which Fogelin repeats seven times (toextractits full flavour). C. S. Peirce, wholate inlife took an interest in Hume's argument, conjectured that Hume hoped to provide a general disproof of all miracles that would not require "a minute analysis of each story"; such a procedure was in fact popular amongthe miracle debunkers ofHume's day, forexample, Rev. Thomas Woolston, whose books were extremely popular.5 Hume's boast of "a direct and full proof might be assumed, offhand, to augur an a priori argumentbased on the comparison ofideas; butitmust notbe forgotten that back in the Treatise (for which the essay "Of Miracles" was originally drafted6) Hume defines a "proof" as an argument "deriv'd from the relation of cause and effect."7 There he contrasts "proofs" explicitly with the type of assured knowledge that comes "from the comparison ofideas" (T 124). Still, Hume requires that proofs, despite their empirical origin, must nonetheless be "entirely free from doubt Volume XVII Number 2 105 KENNETH G. FERGUSON and uncertainty" (T 124); proofs, then, must be superior to ordinary causal arguments that are able to offer only a degree of probability (T 124). By his own examples, namely, that "the sun will rise to-morrow" and "all men must dye" (T 124), likewise from the essay "Of Miracles" itself, that "lead cannot, of itself, remain suspended in the air" and that "fire consumes wood" (E 114), Hume makes it clear that "proofs" are simply to be causal arguments uniformly confirmed by a great wealth of past experience: empirical conclusions so sound that any who deny them "wou'd appear ridiculous" (T 124). Taking Hume's definition of "proof" to heart, we might infer that his "direct and full proof against miracles is not then to be an a priori or deductive conclusion, but instead merely a fully convincing induction, along the Unes of"all men must dye." This,would appear to dispel Fogelin's hope to portray the argument as a priori; but the logic ofHume's special proofagainst miracles is somewhat complicated. As Hume's own selection of examples verify, a proof, at least ordinarily, issues in the confirmation of a law of nature. This contrasts with the special proof against miracles where the object is, of course, not to defend a law of nature, but rather to exploit reasoning about the formation of such laws to prove a result regarding the occurrence of miracles. The proof against miracles, consequently, concerns causes, but is not necessarily a causal argument in the ordinary sense. Indeed, it might be properly thought ofas a "meta-causal" argument, if such a term is allowed. And such an argument may potentially have, as Fogelin proposes, an a priori... (shrink)

What do we mean when we say we "know" something? What is this knowledge and how do we come by it? What exactly counts as an object of knowledge? And on what basis do we defend our claims to know against thosethe skepticswho deny that knowledge is possible or that our criteria for knowing can ever be satisfied? These questions and many others are addressed in this fascinating collection of essays by leading philosophers, who discuss the nature, meaning, and extent (...) of human knowledge. Included are works by Robert Almeder, William P. Alston, Robert P. Amico, Roderick M. Chisholm, Edmund L. Gettier, Richard Feldman, Peter D. Klein, Keith Lehrer, Kenneth G. Lucey, John Pollock, and others. Several essays are original to this collection and break new ground on such issues as the Problem of the Criterion. (shrink)

This collection of essays explores the philosophy of human knowledge from a multitude of perspectives, with a particular emphasis upon the justification component of the classical analysis of knowledge and with an excursion along the way to explore the role of knowledge in Texas Hold ‘Em poker. An important theme of the collection is the role of knowledge in religion, including a detailed argument for agnosticism. A number of the essays touch upon issues in philosophical logic, among them a fascinating (...) new counter-example to Modus Ponens. The collection is rounded out with essays on causality and the philosophy of mind. The author’s perspective on the philosophy of human knowledge is fresh and challenging, as evidenced by essays entitled “On Epistemic Preferability;” “On Being Unjustified;” “The Logic of ‘Unless’” and “Is ‘This sentence is true.’ True?” An interesting feature of The Logic of Philosophy: Pesky Essays is the inclusion of responses to several of its key essays, contributed by such prominent contemporary philosophers as Roderick Chisholm, Ted Sider and Tomas Kapitan.

Evil: A Critical Primer argues that our colloquial conception of evil, as related exclusively to the moral domain, is usefully illuminated by attending to historical and cultural context and cross-cultural comparison.

Classic deductive logic entails that once a conclusion is sustained by a valid argument, the argument can never be invalidated, no matter how many new premises are added. This derived property of deductive reasoning is known as monotonicity. Monotonicity is thought to conflict with the defeasibility of reasoning in natural language, where the discovery of new information often leads us to reject conclusions that we once accepted. This perceived failure of monotonic reasoning to observe the defeasibility of natural-language arguments has (...) led some philosophers to abandon deduction itself (!), often in favor of new, non-monotonic systems of inference known as `default logics'. But these radical logics (e.g., Ray Reiter's default logic) introduce their desired defeasibility at the expense of other, equally important intuitions about natural-language reasoning. And, as a matter of fact, if we recognize that monotonicity is a property of the form of a deductive argument and not its content (i.e., the claims in the premise(s) and conclusion), we can see how the common-sense notion of defeasibility can actually be captured by a purely deductive system.
