1. Here is a very simple game. You come up with a number and I come up with a number. If I come up with the higher number, I win; otherwise you win. You go first. Call this ‘The Very Simple Game’. Few would play it if they had to go first and many if they are guaranteed to go second.2. Here is another one. You come up with a number n and I come up with a number m. If m times 1/ n > 1, then I win; if not, then you win. You go first. Call this ‘Still The Very Simple Game’. Since I win just in case m is greater than n, this game collapses into The Very Simple Game. Few people will play it if they have to go first.3. Here is a third one. Let us call it ‘Looks Like A Tricky Game’. Suppose you have a choice between exactly two actions: keep holding on to some thing t ; hand t over to me and accept my offer to give you, with some probability p, some thing with utility m.Suppose, you are a maximizer of expected utility with …

Philip Kitcher recently argued for a reconstruction in philosophy. According to him, the contemporary mainstream of philosophy has deteriorated into something that is of relevance only to a few specialists who communicate with each other in a language nobody else understands. Kitcher proposes to reconstruct philosophy along two axes: a knowledge axis and a value axis. The present article discusses Kitcher's diagnosis as well as his proposal of a therapy. It argues that there are problems with both, and it ends with an alternative view of what some core problems of the profession currently are.

This paper argues against common views that at least in many cases Robert Nozick is not forced to deny common closure principles. More importantly, Nozick does not – despite first (and second) appearances and despite his own words – deny closure. On the contrary, he is defending a more sophisticated and complex principle of closure. This principle does remarkably well though it is not without problems. It is surprising how rarely Nozick’s principle of closure has been discussed. He should be seen not so much as a denier of closure than as someone who’s proposing an alternative, more complex principle of closure.

Amongst those who answered Molyneux’s question in the negative or at least not in the positive, George Berkeley is of particular interest because he argued for a very radical position. Most of his contribution to the discussion can be found in his Essay towards a New Theory of Vision. I will give an exposition of his view (2) and then move on to a critical discussion of this kind of view, - what one could call the “Berkeleian view” (3). I think that the problems of what has become a standard negative answer to the question (mainly brought forward by empiricists) become very clear in Berkeley’s case and one can also learn a lot from this.

This paper argues that three plausible principles are mutually inconsistent: One ought to assert only what one knows; If it is proper to assert some proposition q, then it is, barring special and not very common circumstances, proper to assert any proposition p from which q has been competently inferred; and Some propositions are both properly assertible and known by competent inference from propositions which one does not know. Each pair of two principles constitutes an argument against the remaining principle, but which principle should one drop?

Kant's political philosophy in general is characterized by two aspects which sometimes compete with each other and sometimes supplement each other: an individualist element on the one hand and a social or "communitarian" element on the other hand. This paper deals with Kant's theory of private property. It attempts to show something that is usually overlooked in the secondary literature: that Kant has two, not just one argument for property. One is based on his theory of freedom and expresses the individualist aspect of his thinking. The other argument is based on Kant's principle of right and expresses the social aspect of his political thought. Despite some problems with his arguments the complexity of Kant's theory remains impressive.
