One can interpret the No Probabilities for Acts-Principle, namely that any adequate quantitative decision model must in no way contain subjective probabilities for actions in two ways: it can either refer to actions that are performable now and extend into the future or it can refer to actions that are not performable now, but will be in the future. In this paper, I will show that the former is the better interpretation of the principle.

While it can be shown that Spohn’s principle doesn’t hold in the case of strategic thinking, one could also question whether it holds in the case of non-sequential decision making. For Spohn’s reason for adopting his principle in the first place can be criticized.

This book stands in the tradition of philosophers who advance the rationality of faith. Yet, this book goes beyond their accounts, for it not only defends the view that faith can be termed rational, but it also considers the different senses in which faith can be termed rational. While this book advances the idea that faith as a general category can be termed rational, it does not investigate in a detailed way whether there are arguments for the rationality of particular (...) faiths which would go beyond the arguments for the rationality of faith as a general category. Besides discussing whether betting on God in Pascal’s wager and believing in miracles are forms of the rationality of faith, I will provide unique solutions to the problem of evil and the paradoxes of omnipotence and omniscience.

According to Reid (1969, 283) motives are an ens rationis. Because of that they may influence to action, but they do not act as causes or as agents, that is motives are only advisory (cf. Seebaß 1993, 329; Lehrer 1989, 210). Instead motives presuppose an efficient cause, namely an agent (cf. Rowe 1991, chapter 4), and the agent"s freedom (Reid 1969, 284). In opposition to Leibniz (1994, 84-85) who defends subtle reasons Reid (1969) claims that motives have to be conscious (...) (cf. Seebaß 1993, 269). For to "be influenced by a motive of which I am not conscious, is, ..., an arbitrary supposition without any evidence, ... ." (Reid 1969, 285). (shrink)

This book opens up a new area of research by not only considering the rationality of such diverse phenomena as ordinary emotions, generalized anxiety disorder, social phobia, psychotic depression, major depressive disorder, and bipolar disorder, but also by evaluating the question whether the vagueness of these diverse disorders and emotions poses an obstacle to the rationality of these phenomena. As these emotional phenomena turn out to be vague on many different levels, an explanation is found for the millennia long dispute (...) of which kind of phenomena fall under the emotions and whether such diverse phenomena as hope and alexithymia fall under the emotions. Since vagueness can be most easily identified in mixed feelings, the rationality of mixed feelings will also be dealt with. (shrink)

Thomas Reid's philosophy of psychology is remarkably up to date. Surprisingly, Reid's account of instincts doesn't diverge greatly from Tinbergen's more contemporary account. Reid's claims with regard to appetites and desires can be made relevant to current insights.

Spohn's decision model, an advancement of Fishburn's theory, is valuable for making explicit the principle used also by other thinkers that 'any adequate quantitative decision model must not explicitly or implicitly contain any subjective probabilities for acts.' This principle is not used in the decision theories of Jeffrey or of Luce and Krantz. According to Spohn, this principle is important because it has effects on the term of action, on Newcomb's problem, and on the theory of causality and the freedom (...) of the will. On the one hand, I will argue against Spohn with Jeffrey that the principle has to be given up. On the other, I will try to argue against Jeffrey that the decision-maker ascribes subjective probabilities to actions on the condition of the given decision situation. (shrink)
