In this paper Beebee argues that the problem of induction, which she describes as a genuine sceptical problem, is the same for Humeans than for Necessitarians. Neither scientific essentialists nor Armstrong can solve the problem of induction by appealing to IBE, for both arguments take an illicit inductive step.

ABSTRACT ABSTRACT: In metaphysics, the adjective ‘Humean’ is used to describe positions that deny the existence of any necessary connection or causal influence in concrete reality. This usage has been significantly reinforced by David Lewis’s employment of ‘Humean’ in the phrase ‘Humean supervenience’. It is, however, not at all clear that this usage is appropriate. Lewis himself raised a doubt about it.

There is an assumption common in the philosophy of mind literature that kinds in our sciences—or causal kinds, at least—are individuated by the causal powers that objects have in virtue of the properties they instantiate. While this assumption might not be problematic by itself, some authors take the assumption to mean that falling under a kind and instantiating a property amount to the same thing. I call this assumption the “Property-Kind Individuation Principle”. A problem with this principle arises because there (...) are cases where we can sort objects by their possession of common causal powers, and yet those objects do not intuitively form a causal kind. In this short note, I discuss why the Property-Kind Individuation Principle is thus not a warranted metaphysical assumption. (shrink)

I discuss puzzles involving coinciding material objects (such as statues and their constitutive lumps of clay) and propose solutions.

A tropel is a particular property: the redness of a rose, the roundness of the moon. It is generally supposed that tropes are individuated by primitive quantity: this redness, that roundness. I argme that the trope theorist is far better served by individuating tropes by spatiotemporal relation: here redness, there roundness. In short, tropes are not this-suches but here-suches.

Scientific Essentialism defends the view that the fundamental laws of nature depend on the essential properties of the things on which they are said to operate, and are therefore not independent of them. These laws are not imposed upon the world by God, the forces of nature, or anything else, but rather are immanent in the world. Ellis argues that ours is a dynamic world consisting of more or less transient objects that are constantly interacting with each other, and whose (...) identities depend on their roles in these processes. The laws of nature are metaphysically necessary, and consequently, there are necessary connections between events. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:66 IN DEFENCE OF KEMP SMITH D. C. Stove argues against Kemp Smith's contention that Hume's philosophy "was intended not to subvert but to endorse our natural beliefs" in general, and our belief in the Causal Principle in particular. His arguments are insufficient. Kemp Smith does not need to deny that the falsity of the Causal Principle is believed by Hume to be possible in the strongest of Stove's (...) three suggested 2 senses: it is not merely self-consistent, but the Principle is unverifiable and unconfirmable in the sense that no empirical proposition is relevant to its truth. However, to say flatly that its falsity is possible is to say that it is not impossible in any way at all; and that is what is at stake both in Hume's letter to Stewart and in the use Kemp Smith makes of it. If Hume had written a letter to Stewart or to any scientific enquirer urging him to desist from his labours on the ground that "something may begin to exist, or start into being without a cause," he would have been a fool, and in representing Hume's position in this way Stewart is in fact calling Hume a fool. It is not surprising that Hume is indignant. The problem is whether, and how, one can hold both that the Causal Principle is undeniably true and that it can be supported neither by deductive nor by inductive argument, and whether Hume on the most reasonable interpretation of his published works held both these views. Clues to the answer lie in the in tradition of sceptical philosophy, and in the difference between a cause and a reason. Hume's philosophy is indeed, as he says, 'very sceptical'. But scepticism is a kind of philosophy with a long history, from Sextus Empiricus to Bayle, and it is reasonable to suppose that Hume was aligning himself with this position, especially since so much of the argument in 67 the Treatise is derived from Bayle. But sceptics do not behave otherwise than ordinary men. Scepticism is not directed against everyday beliefs but again.st arguments: this is a point on which Sextus insists." It would not be the part of a sceptic to doubt that every event has a cause, but to refute all arguments purporting to show that such is the case. To assert "that any thing might arise without a Cause" would not be scepticism, but an inverse dogmatism: to infer from a philosophical argument a belief about the real world that is at variance with everyday belief. The crucial step in Stove's argument occurs in his gloss of Hume's claim that he had maintained "that our Certainty of the Falsehood of that Proposition proceeded neither from Intuition nor Demonstration; but from another Source" phrase "sic., experience, of course". This could be misleading. It could mean that Hume here claims that experience gives us reason to believe that the Causal Principle is true; and this Hume has denied, as Stove urges ad loc. But nothing in what Hume says in his letter requires us to interpret him thus. And his sceptical principles tell against it: an argument from experience, whether inductive or by analogy or whatever, is still an argument and thus liable to sceptical attack. What Hume could mean, and what Kemp Smith took him to mean, is that our experience causes us to regard the principle as necessary: experience is not a premise in any sort of argument at all, but a causal explanation for a universal propensity to believe in the Causal Principle. It is true that Hume's citation as analogues of such empirical affirmations as "That Caesar existed" is misleading. But it is not in fact the case that Hume represents these as in any way 'parallel' with the Causal Principle: he says only that, like it, They are believed without recourse to Reason and Intuition. In 68 point of fact, Stove is going a bit far when he says that this is (like "There is such an Island as Sicily") an observation-statement; but that point is hardly relevant here. It is worth noting that in the offending passage... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:ST. THOMAS ON ANGELIC TIME AND MOTION J. J. MACINTOSH University ofCalgary Calgary, Alberta, Canada A. THOMAS'S STANDARD DOCTRINE: THE NEED FOR ASINGLE TIME. T HERE IS an under-discussed problem about time for St. Thomas. Most discussions of his views on time center around either the question of God's foreknowledge or around the notions of eternity and aeviternity. Even those discussions which deal directly with Thomas's views on time (...) ignore the issue I wish to discuss here.' The problem is this: St. Thomas held both that there is a single time, created by God, and that there are three distinct times: two for the angels, and one for the rest of creation. Moreover, he seems, fairly explicitly, to have been unwilling to adopt either of the obvious ways out of this apparent contradiction. Thomas believed, and often said, that time is unitary, and typically offered an Aristotelian reason for the claim: "the true reason why time is one, is to be found in the oneness of the first movement by which, since it is most simple, all other movements are measured. Therefore time is referred to that movement, not only as a measure is to the thing measured, but also as accident 1 See, for example, Piero Ariotti, "Celestial reductionism of time: on the scholastic conception of time from Albert the great and Thomas Aquinas to the end of the 16th century," Studia Internationale Filosofia 4 (1972): 91-120, and Antonio Moreno, "Time and Relativity: Some Philosophical Considerations," The Thomist 45 (1981): 62-79. I have referred to this problem earlier in "Time and St. Thomas" (in To Myselffrom Others, ed. David Miller [Warwick: University of Warwick, 1989)), and in "Aquinas, Ockham, and Prior (and the unexpected examination),'' Auckland Philosophy Papers, no. 1 (1990). 547 548 J. J. MACINTOSH is to subject; and thus receives unity from it."2 Moreover, such a doctrine is necessary if what he tells us about the foreknowledge of God, and God's inability to change the past,3 not to mention his views on the knowledge that angels and demons have of what is genuinely future, is to be correct. Briefly, those views commit him to a view of a single time that is linear past, and is nonbranching future as well.4 There is some exegetical question as to whether or not his views on time, contingency, and freedom led him to adopt a truth-gap account of genuinely future tense contingent propositions, but that the singleness of time is required has not been questioned.5 This is not the place to deal with the difficulties Aquinas faced concerning God's foreknowledge, but a brief introductory word is in order to show how central the singleness of time is for his thought in this area. Since all past- and present-tense truths have necessity per accidens (that is, they concern matters which are now irrevocable), the class of contingent truths is a proper subset of genuinely future-tense claims. A proper subset because 2 Summa Theologiae, I, q. 10, a. 6 c (hereafter cited as sn; English translation by the Fathers of the English Dominican Province, 5 vols., (1920; reprint, Westminster, Maryland: Christian Classics, 1981). This is the translation I have standardly used, sometimes with slight changes, but I have also made use of the translation by the Blackfriars (61 vols. [London: Blackfriars, in conjunction with Eyre and Spottiswood, 1964-81], hereafter cited as Blackfriars). 3 Thus, for example, "God can make the existence of an angel not future; but He cannot cause him not to be while he is, or not to have been, after he has been" (ST I, q. 10, a. 5, ad 3). 4 By contrast, Ockham, for example, adopted an implicit tense logic with branching future possibilities. As far as I know, no mediaeval thinker allowed branching pasts. For a discussion of that possibility, see John Mackie, Truth, Probability and Paradox: Studies in Philosophical Logic (Oxford: Clarendon Press, 1973).
