Does action always arise out of desire? G. F. Schueler examines this hotly debated topic in philosophy of action and moral philosophy, arguing that once two senses of "desire" are distinguished - roughly, genuine desires and pro attitudes - apparently plausible explanations of action in terms of the agent's desires can be seen to be mistaken. Desire probes a fundamental issue in philosophy of mind, the nature of desires and how, if at all, they motivate and justify our actions. At (...) least since Hume argued that reason "is and of right ought to be the slave of the passions," many philosophers have held that desires play an essential role both in practical reason and in the explanation of intentional action. G. F. Schueler looks at contemporary accounts of both roles in various belief-desire models of reasons and explanation and argues that the usual belief-desire accounts need to be replaced. Schueler contends that the plausibility of the standard belief-desire accounts rests largely on a failure to distinguish "desires proper," like a craving for sushi, from so-called "pro attitudes," which may take the form of beliefs and other cognitive states as well as desires proper. Schueler's "deliberative model" of practical reasoning suggests a different view of the place of desire in practical reason and the explanation of action. He holds that we can arrive at an intention to act by weighing the relevant considerations and that these may not include desires proper at all. (shrink)

In this paper I will argue that the latter group [of Non-Humeans] is correct. My argument focuses on practical deliberation and has two parts. I will discuss two different problems that arise for the Humean Theory and suggest that while taken individually each problem appears to have a solution, for each problem the solution Humeans offer precludes solving the other problem. I will suggest that to see these difficulties we must take seriously the thought that we can only understand an (...) agent’s reasons for her action by looking at her actual or possible practical deliberation.

The ‘error theory’ holds that all normative claims are false. Of course, if there is any reason to believe the error theory then, since it would be a reason to believe something, that would show the error theory itself to be false. A recent book (Streumer, 2017) tries to block this argument by arguing on the basis of the claim that the error theory itself can’t be believed that there can be no reason to believe it. This is a paradoxical (...) conclusion since it leaves the possibility that the error theory is true even though it is impossible to believe it and we can have no reason to believe it. In this paper I argue for a different paradox. Even if we can believe the error theory, we are committed to rejecting it, but this still leaves normative skepticism unanswered. (shrink)

We formulate a discrete quantum-mechanical precursor to spacetime geometry. The objective is to provide the foundation for a quantum mechanics that is rooted exclusively in quantum-mechanical concepts, with all classical features, including the three-dimensional spatial continuum, emerging dynamically.

In the first part of this paper a logic is defined for propositions whose probability of being true may not be known. A speaker's beliefs about which propositions are true are still interesting in this case. The meaning of propositions is determined by the consequences of asserting them: in this logic there are debates which incur certain costs for the protagonists.The second part of the paper describes the mathematics of the resulting logic which displays several novel features.
