SummaryBecause it is not generally appreciated that Hume's analysis of the causal tie as radically contingent or ‘irrational’ is bound up with his specialised theory of cognition, its historical position is widely misconceived. Even a rationalist like Spinoza would agree that if, as Hume maintains, the causal tie holds between items each of which is‘ adequately’ grasped independently of the other, i.e. between what Spinoza calls ‘substances’, then the tie is indeed irrational. Also, Kant does not attempt to show that the causal tie, as Hume sees it, is not irrational. His anti‐Humean result is based on the prior denial Humean causal fundaments are available in experiential cognition as we know it.RésuméLa position historique de Hume est généralement mal comprise parce qu'on ne voit pas que son analyse de la relation causale comme étant radicalement contingente ou »irrationnelle« est liée à sa théorie particulière de la connaissance. Même un rationaliste tel que Spinoza accorderait que la causalité est en effet irrationnelle si elle relie, ainsi que le prétend Hume, deux choses saisies indépendamment, c'est‐à‐dire deux substances selon Spinoza. Même Kant ne cherche pas à démontrer que le lien causal tel que Hume le voit n'est pas irrationnel. Son résultat anti‐humien est basé sur la négation préalable que le fondement de la causalité puisse être tiré de la connaissance expérimentale.ZusammenfassungWeil man im allgemeinen nicht berilcksichtigt, dass Humes Analyse der kausalen Verknüpfung als einer radikal kontingenten oder »irrationalen« Relation mit seiner besonderen erkennt‐nistheoretischen Position verbunden ist, wird deren historische Bedeutung oft missverstanden. Sogar ein Rationalist wie Spinoza würde zugestehen, dass die Verknüpfung irrational sein muss, wenn sie zwischen Substanten irn Sinne Spinozas, d.h. zwischen Dingen bestehen soll, die unabhängig voneinander adäquat erfasst werden, wie Hume das behauptet. Auch Kant versucht nicht zu zeigen, dass eine Kausalverknüpfung, so wie Hume sie auffasst, nicht irrational sei. Denn er bestreitet ja gerade, dass kausale Grundlagen auf Grund gewöhnlicher Erfahrung überhaupt gefunden werden können

Though, in view of Descartes' challenge to the epistemological credentials of "reason" early in the Meditations, one expects him to resist the claim that the professedly invulnerable cogito argument works through the suppressed premise "Everything that thinks, exists," interpreters have been hard-pressed to convert comprendre here into pardonner. Loath to convict Descartes of confusing a psychological point about inferential process with a logical one about the conditions for validity, many are driven to implausible construals, for example, the ingenious performative construal, on which "cogito" does not express a premise. In this fast-paced study Jerrold Katz, calling on his Chomsky-inspired theorising about natural languages, offers a via media. At the core is the thesis that validity is not always a matter of logical form--hence a rejection of the view whose contemporary prestige derives from Frege. According to Katz, the validity of analytic entailments is a function not of logical form but of the senses of the contributing linguistic elements. The cogito argument, Katz maintains, falls into this class. Thus, comprendre avec pardonner: Descartes is not being evasive when he holds that there is an argumentational move from "cogito" to "sum" while denying that the argument, as presented, is enthymematic.

Registrants for the academic study of philosophy, expecting an encounter with special cognitive products, regal truths, are soon enough disabused. Philosophy, its supposedly special access to the structure of things exploded, is relegated to sundry tasks of intellectual hygiene. I track down the source of the unrealistic view, anatomising what has a strong claim to be regarded as the regal enterprise’s inau¬gural reasoning—in Plato. When professionals consider the successor activity that is called ‘philosophy,’ they should therefore wonder about the label. The deposition of she who was once known as Queen of the Sciences is, I argue, really the end of philosophy. Does the prevail¬ing professional attitude attest to mere nostalgia? In fact, the view of philo¬sophy as (say) conceptual enquiry inherits some of the fantasy. To the extent that continued use of the label is internally justified, that signals a deeper mistake on the part of the users about the truth.

1. The distinction between the functions of sense and intellect in cognition is first given its modern form by Kant. According to one influential commentator, Jonathan Bennett, “Kant’s breakthrough” in fact consists precisely in liberating himself from his predecessors’ misconceptions in this regard. It is true that the categorial duality of receptivity and spontaneity—of intuition and concept—is not to be found in the major classical writings prior to Kant. In its place, one encounters a relativized distinction. The empiricist Hume, for example, describes a conceptual element or “idea” as differing only in “vivacity” from an item of sensory intake or “impression,” and the rationalist Leibniz says of a state of “pure” intellection that it differs from a perceptual state in being clear of the residuum of cognitive “confusion” which taints the latter.

In Descartes: The Project of Pure Enquiry, Bernard Williams supplies an interpretation of Descartes's Meditations in which the meditator's clean sweep of initial beliefs is justified by a stance that abrogates all practical pressures: the stance of pure enquiry. Otherwise, Williams explains, it would not be reasonable to set many of the initial beliefs aside. Nowhere, however, does Descartes assert that his approach is in this sense ?pure?. It would of course be preferable if the meditator's rejection of all the initial beliefs did not require an abrogation of the conditions that govern everyday belief-formation and assessment. I supply a reading that accomplishes this. The key to this reading is recognition that Descartes is a thinker of his time, a time when the pre-modern worldview was being systematically rejected. I show, in this regard, that when Descartes characterizes a belief as ?uncertain?, this has the implication that the belief is false. And, certainly, the rational policy, without need for any special stance, is to reject falsehoods

In what respect, if any, is Kant a distinctively “critical” thinker? How does Kant’s “transcendentalism” differentiate his practice in metaphysics from that of the philosophers of the Cartesian tradition? How much does the success of Kant’s enterprise depend on the viability of the idea of the synthetic a priori? The issues that these questions raise came to a head for Kant in the attack on his novelty by the Leibnizean Johann August Eberhard, an attack to which Kant responded at length in the sarcastically titled On a discovery according to which any new critique of pure reason has been made superfluous by an earlier one. Unfortunately, Kant’s apology is quite inconclusive. In this discussion, in an effort to shed some light on the murk, I supply text-sensitive analyses of the various key notions. It emerges that while, as Eberhard complained, the “critical” turn is not at all a methodological novelty, Kant’s procedure does mark a departure from traditional metaphysics, though not one that he himself describes at all clearly. Kant’s “transcendentalism” ultimately constitutes an open-ended and ever-widening interrogation of logical possibility; hence an interrogation that, contrary to what Kant himself claims, can never furnish what legitimately counts as “proof.”
