There is a current debate about the extent to which Academic Freedom should be permitted in our universities. On the one hand, we have traditionalists who maintain that Academic Freedom should be unrestricted: people who have the appropriate qualifications and accomplishments should be allowed to develop theories about how the world is, or ought to be, as they see fit. On the other hand, we have post-traditional philosophers who argue against this degree of Academic Freedom. I consider a conservative version (...) of post-traditional philosophy that permits restrictions on Academic Freedom only if the following conditions are met, Condition 1: The dissemination of the results of a given research project R must cause significant harm to some people, especially to people from oppressed groups. Condition 2: Condition 1 must possess strong empirical support, and which accepts the following assumptions: (1) there is a world of objective facts that is, in principle, discoverable, (2) rational means are the means of discovering it and, (3) rational means requires strong empirical support. I define strong empirical support for an hypothesis h on evidence e in probabilistic terms, as a ratio of posterior to prior probabilities substantially exceeding 1. I now argue in favour of a research policy that accepts unrestricted Academic Freedom. My argument is that there is a formal and general quandary that arises within the standard theory of probability when we apply this account of empirical support to a set of possible causal hypotheses framed in such a way that the “reverse probabilities”, pr(e/h) are 1. I consider various possible ways to escape this quandary, none of which are without difficulties, concluding that a research policy allowing for unrestricted Academic Freedom is probably the best that we can hope for.

The central theme of this study is that Descartes is a teacher who develops his arguments for the different philosophical orientations of his students. Indeed, according to Cunning, so respectful is Descartes of their orientations that he actually misrepresents his own view in the Meditations on central doctrinal matters like the basis for dualism. The exegetical argument for this is the central argument of the book, though many other aspects of the Meditations are discussed in novel and interesting ways. Descartes (...) describes himself as establishing the duality of mental and physical substances in two stages in the Meditations. It is in Meditation II, he says in the Fourth Replies, where he shows that a .. (shrink)

There is a broad distinction in Descartes’s writings between doctrine and method. The staying power of these two elements has been unequal. Descartes’s doctrinal influence on contemporary epistemology has been largely as a foil against which some of its major currents have been developed. Few contemporary philosophers have adopted his positive doctrines. The situation is brighter on the methodological side. Here, Descartes’s practice of beginning with common sense and moving, step by step, to philosophical conclusions is a model much admired (...) by contemporary philosophers. Still, the negative verdict on doctrine stands as the main verdict. I maintain that this verdict is undeserved I first distinguish between Descartes’s general epistemology and the purpose to which he puts it – the quest for certainty. I then argue for a positive verdict for his general epistemology. I do so by showing that Descartes has a non-normative account of knowledge but an “ethics of responsible belief ” account of epistemic normativity. Unlike some contemporary accounts of epistemic responsibilism, e.g. Bonjour, in which epistemic responsibility is a condition for knowledge, on Descartes’s account, knowledge is a condition for epistemic responsibility. Descartes thus anticipates what Sylvan calls the “knowledge-first” approach in contemporary epistemology, which I defend in the paper. Relying on Audi’s distinction between “sources” and “reasons,” I show that Descartes’ analysis of knowledge proper, which I also defend in the paper, anticipates and improves on the “factive access” analysis of knowledge due to McDowell.

Our objectives in this paper are, first, to identify several puzzling aspects of the “Trilemma Argument” of Section 6 against the Sense Datum Theory; second, to resolve these puzzles by reconstructing the Trilemma Argument; third to point to a distinction Sellars makes between two versions of the Sense Datum Theory, the “nominalist” version and the “realist” version; fourth, to reconstruct Sellars’s arguments against both; and, finally, to find in an earlier paper, “Is There a Synthetic A Priori?” that his argument (...) against the second version, assumed but not actually given in EPM, is against property realism and depends on taking language expressing propositional perception as fundamental and language expressing non-propositional perception as incomplete and derivative from the former.

My purpose in this paper is to argue for two separate, but related theses. The first is that contemporary analytic philosophy is incoherent. This is so, I argue, because its methods contain as an essential constituent a conception of intuition that cannot be rendered consistent with a key tenet of analytic philosophy unless we allow a Bayesian-subjectivist epistemology. I argue for this within a discussion of two theories of intuition: a classical account as proposed by Descartes and a modern reliabilist (...) account as proposed by Kornblith, maintaining that reliabilist accounts require a commitment to Bayesian subjectivism about probability. However, and this is the second thesis, Bayesian subjectivism is itself logically incoherent given two simple assumptions: (1) that some empirical propositions are known and (2) any proposition that is known is assigned a degree of subjective credence of 1. I establish this using a formal reductio proof. I argue for the first thesis in section 2 and for the second in section 3. The final section contains a summary and conclusion. (shrink)

Leibniz’s Most Determinate Path Principle in Tentamen Anagogicum is an optimization-type law of physics falling into the category of “final cause,” one of “two realms” under discussion there. The other is the “mechanistic/causal.” To be explanatory for Leibniz laws have to be grounded in a causal agency, in the case of the mechanistic realm, the grounding agency is material. I accept, and philosophically defend through a thought experiment, a modern form of this principle, “If a pattern of events is not (...) governed by the laws of chance (are not statistically independent) then there is a causal agency operating to link the events” (The General Version of Leibniz’ Postulate). In Leibniz exegesis, against McDonough, I argue that optimization laws lack an appropriate grounding agency : they are true, predictive and heuristic but not explanatory. So the mechanistic realm is explanatorily fundamental for Leibniz. But Planck maintains the converse: the optimization laws (The Principle of Least Action in his case) are fundamental. (Planck’s Postulate) I defend this postulate against Leibniz and show that if both postulates are right, and a certain plausible condition in theoretical physics holds, the ground for the explanatory power of such laws must lie in Divine Reason.

Evidentialism is the doctrine that rational belief should be proportioned to one’s evidence. By “one’s evidence,” I mean evidence that we possess and know that we possess. I specifically exclude from “evidence” the following: information of which we are unaware that our brain might rely on in constructing experience or in the formation of beliefs. My initial interest is with the doctrine of Evidentialism as it applies to a quandary that arises in the Sci-Fi movie Contact, the “Contact Paradox” as (...) I will call it. In this movie one of the main characters, Ellie, is a cosmologist working in a radio-telescope research facility searching for signals from intelligent life in the cosmos. The entity whose epistemological status is at issue in her quandary is her deceased father but there is an obvious parallel between the quandary of a rational believer in God and Ellie’s quandary, a parallel extensively explored in the movie itself. My first thesis is that in Ellie’s case Evidentialism is false: in certain cases, it is rational to believe in the existence of an entity in spite of the fact that the empirical evidence overall is contrary, and the Contact Paradox is one such case. Later in the paper I turn attention to the issue of Evidentialism regarding beliefs in the existence of God. My second thesis is that Evidentialism is false there as well. (shrink)
