    Causal Dependence and Multiplicity
    Philosophy 60 (232): 215-230. 1985.
    In "Causes and "If P, Even If X, still Q," Philosophy 57 (July 1982), Ted Honderich cites my "The Direction of Causation and the Direction of Conditionship," journal of Philosophy 73 (April 22, 1976) as an example of an account of causal priority that lacks the proper character. After emending Honderich's description of the proper character, I argue that my attempt to account for one-way causation in terms of one-way causal conditionship does not totally lack it. Rather than emphasize the singul…Read more

    Begging the Question
    Analysis 32 (6): 197-199. 1972.
    A primary purpose of argument is to increase the degree of reasonable confidence that one has in the truth of the conclusion. A question begging argument fails this purpose because it violates what W. E. Johnson called an epistemic condition of inference. Although an argument of the sort characterized by Robert Hoffman in his response (Analysis 32.2, Dec 71) to Richard Robinson (Analysis 31.4, March 71) begs the question in all circumstances, we usually understand the charge that an argument is …Read more

    The primary objects of perception
    Mind 85 (338): 189-208. 1976.
    The primary objects of hearing are sounds: everything we hear we hear by hearing a sound. (This claim differs from Berkeley’s that we hear only sounds and from Aristotle’s that we only hear sounds.) Colored regions are primary objects of sight, and pressure resistant regions are primary objects of perception by touch. By definition, the primary objects of perception are physical. The properties of the primary objects of perception are exactly the properties sense-datum theories attribute to se…Read more

    The Direction of Causation and the Direction of Time
    Midwest Studies in Philosophy 9 (1): 53-75. 1984.
    I revise J L Mackie's first account of casual direction by replacing his notion of "fixity" by a newly defined notion of "sufficing" that is designed to accommodate indeterminism. Keeping Mackie's distinction between casual order and casual direction, I then consider another revision that replaces "fixity" with "one-way conditionship". In response to the charge that all such accounts of casual priority beg the question by making an unjustified appeal to temporal priority, i maintain that one-way…Read more

    Symposium Contribution on Events and Their Names by Jonathan Bennett
    Philosophy and Phenomenological Research 51 (3). 1991.
  • What is a Truth Functional Component?
    Logique Et Analyse 52 4483-486. 1970.
    Although the truth value (falsity) of "Henry knows that (dogs live in trees and beavers chew wood)" remains unchanged no matter what sentence is substituted in it for "beavers chew wood", we want not to regard the second as a truth functional component (tfc) of the first. Many definitions of "tfc" (e.g., Quine's) fail to insure satisfaction of the following principle: if p is a component of r which is in turn a component of q, then p is a tfc of q if and only if 1) p is also a tfc of r, and 2) r…Read more

    Locke thought it was a necessary truth that no two material bodies could be in the same place at the same time. Leibniz wasn't so sure. This paper sides with Leibniz. I examine the arguments of David Wiggins in defense of Locke on this point (Philosophical Review, January 1968). Wiggins’ arguments are ineffective.

    Infinity and vagueness
    Philosophical Review 84 (4): 520-535. 1975.
    Many philosophic arguments concerned with infinite series depend on the mutual inconsistency of statements of the following five forms: (1) something exists which has R to something; (2) R is asymmetric; (3) R is transitive; (4) for any x which has R to something, there is something which has R to x; (5) only finitely many things are related by R. Such arguments are suspect if the two-place relation R in question involves any conceptual vagueness or inexactness. Traditional sorites arguments sho…Read more

    Naive mereology studies ordinary conceptions of part and whole. Parts, unlike portions, have objective boundaries and many things, such as dances and sermons have temporal parts. In order to deal with Mark Heller's claim that temporal parts "are ontologically no more or less basic than the wholes that they compose," we retell the story of Laplace's Genius, here named "Swifty." Although Swifty processes lots of information very quickly, his conceptual repertoire need not extend beyond fundamental…Read more

    This article answers John Biro's "Knowability, Believability, and Begging the Question: a Reply to Sanford" in "Metaphilosophy" 15 (1984). Biro and I agree that of two argument instances with the same form and content, one but not the other can beg the question, depending on other factors. These factors include actual beliefs, or so I maintain (against Biro) with the help of some analysed examples. Brief selections from Archbishop Whatley and J S Mill suggest that they also regard reference to a…Read more

    The Fallacy of Begging the Question: A Reply to Barker
    Dialogue 16 (3): 485-498. 1977.
    According to John A Barker, whether an argument begs the question is purely a matter of logical form. According to me, it is also a matter of epistemic conditions; some arguments which beg the question in some contexts need not beg the question in every context. I point out difficulties in Barker's treatment and defend my own views against some of his criticisms. In the concluding section, "Alleged difficulties with disjunctive syllogism," I defend the validity of disjunctive syllogism against t…Read more

  • Causation
    In Jaegwon Kim, Ernest Sosa & Gary S. Rosenkrantz (eds.), A Companion to Metaphysics, Wiley-blackwell. 1994.
    Twenty-one paragraphs in this entry begin with a statement of a view about causation. To help organize the entry, the next sentence then classifies the view as 'prevailing, majority, controversial', or 'minority'. The following brief discussions attempt to be clear and fair. Respect for fairness, however, does not prevent the author from referring to his own views. For example, the author classifies "There is no element of genuine a priori reasoning in causal inference" as a majority view. After…Read more

    Determinates vs. determinables
    Stanford Encyclopedia of Philosophy. 2008.
    Everything red is colored, and all squares are polygons. A square is distinguished from other polygons by being four-sided, equilateral, and equiangular. What distinguishes red things from other colored things? This has been understood as a conceptual rather than scientific question. Theories of wavelengths and reflectance and sensory processing are not considered. Given just our ordinary understanding of color, it seems that what differentiates red from other colors is only redness itself. The …Read more

    Vague numbers
    Acta Analytica 17 (2): 63-73. 2002.
    If there are vague numbers, it would be easier to use numbers as semantic values in a treatment of vagueness while avoiding precise cut-off points. When we assign a particular statement a range of values (less than 1 and greater than 0) there is no precise sharp cut-off point that locates the greatest lower bound or the least upper bound of the interval, I should like to say. Is this possible? “Vague Numbers” stands for awareness of the problem. I do not present a serious theory of vague numbers…Read more

    Causal necessity and logical necessity
    Philosophical Studies 28 (2). 1975.
    Myles Brand and Marshall Swain advocate the principle that if A is the set of conditions individually necessary and jointly sufficient for the occurrence of B, then if C is a set of conditions individually necessary for the occurrence of B, every member of C is a member of A. I agree with John Barker and Risto Hilpinen who each argue that this principle is not true for causal necessity and sufficiency, but I disagree with their claim that it is true for logical necessity and sufficiency. The ori…Read more

    The perception of shape
    In Knowledge And Mind: Phil Essays, Oxford University Press. 1983.
    The central text of this article is Thomas Reid’s response to Berkeley’s argument for distinguishing tangible from visual shape. Reid is right to hold that shape words do not have different visual and tangible meanings. We might also perceive shape, moreover, with senses other than touch and sight. As Reid also suggests, the visual perception of shape does not require perception of hue or brightness. Contrary to treatments of the Molyneux problem by H. P. Grice and Judith Jarvis Thomson, I …Read more

    The asymmetry of the by-relation
    Mind 93 (371): 410-411. 1984.
    Sam signaled a turn by extending his arm out the window. Difficulties in explaining the asymmetry of the by-relation in such examples by reference to acceptable and unacceptable counterfactual conditionals are explored by Hugh McCann in "The Trouble with Level-Generation" ("Mind", October 1982). I refine and defend the following alternative account of one-way dependence of y on x: not only is x necessary for y, but something else, independent from x, is also necessary for y; but there is nothing…Read more
