29Incline Without NecessitatingDialogue 24 (4): 589-. 1985.A stranger runs out of a bank while I am sitting at the wheel of my car waiting for the lights to change; he jumps in beside me, points a gun at me, and says, “Drive me to St. Bruno.” This is Andre Gombay's example, from his excellent paper on duress. The question that interests Gombay and me is: Could I refrain from doing what the gunman asks?

215Does the Brain Lead the Mind?Philosophy and Phenomenological Research 86 (2): 262-265. 2013.Over the last 25 years, experimental findings published by Benjamin Libet have indicated that conscious acts of will are preceded by a characteristic kind of brain event of which the agent is not conscious. It, Libet says, rather than the will, is what causes actions. His discoveries, if correct, would seem to imply that the notion of a free, conscious will is an illusion, and that actions are initiated by neural processes not under conscious control. In what follows it is argued that Libet’s co…Read more

284The definition of enduranceAnalysis 69 (2): 277-280. 2009.David Lewis, following in the tradition of Broad, Quine and Goodman, says that change in an object X consists in X's being temporally extended and having qualitatively different temporal parts. Analogously, change in a spatially extended object such as a road consists in its having different spatial parts . The alternative to this view is that ordinary objects undergo temporal change in virtue of having different intrinsic non-relational properties at different times. They endure, remaining the …Read more

446Objective time flowPhilosophy of Science 43 (3): 337-362. 1976.A theory of temporal passage is put forward which is "objective" in the sense that time flow characterizes the universe independently of the existence of conscious beings. The theory differs from Grunbaum's "mind-dependence" theory, and is designed to avoid Grunbaum's criticisms of an earlier theory of Reichenbach's. The representation of temporal becoming is accomplished by the introduction of indeterministic universe-models; each model representing the universe at a time. The models depict the…Read more

18The evolution of a single trapped ion exhibiting intermittent fluorescence and dark periods may be described either as a continuous process, using differential rate equations, or discretely, as a Markov process. The latter models the atom as making instantaneous transitions from one energy eigenstate to another, and is open to the objection that superpositions of energy states will form which are not covered by the Markov process. The superposition objection is replied to, and two new mathematic…Read more

I propose to develop some of the commonly held implications of this view, and to show that they involve a contradiction. Hence whatever time is, it cannot be the thing corresponding to this particular theory.

73Time and the Physical ModalitiesThe Monist 53 (3): 426-446. 1969.Relative to any point in time, how many possible futures are there? For example, it may rain tomorrow, or again it may not. So it would appear that relative to today, there are at least two possible futures, one involving rain tomorrow and the other not. Of course only one of these two future states of affairs will take place, and in that sense there is only one actual future, though there may be many possible futures. The only hypothesis under which there is, for every instant in time, only one…Read more
