35A Non-Classical Theory of Truth, with an Application to IntuitionismAmerican Philosophical Quarterly 7 (1). 1970.Any "classical" theory of truth will satisfy tarski's criterion ("p" is true if and only if p), And the principle of bivalence (every proposition is either true or false). A non-Classical theory may be obtained by rejecting these principles: - in fact it is shown that rejection of the second entails rejection of the first. If the resulting non-Classical theory is formalized, A system structurally isomorphic to either s4 or s5 is obtained. An attempt is made to show that the essential insights of…Read more

29Indeterminist Free WillPhilosophy and Phenomenological Research 70 (3): 681-690. 2007.The aim of the paper is to prove the consistency of libertarianism. We examine the example of Jane, who deliberates at length over whether to vacation in Colorado (C) or Hawaii (H), weighing the costs and benefits, consulting travel brochures, etc. Underlying phenomenological deliberation is an indeterministic neural process in which nonactual motor neural states n(C) and n(H) corresponding to alternatives C and H remain physically possible up until the moment of decision. The neurophysiological…Read more

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?

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
