The present paper offers an analogical support for the use of rational intuition, namely, if we regard sense perception as a mental faculty that (in general) delivers justified beliefs, then we should treat intuition in the same manner. I will argue that both the cognitive marks of intuition and the role it traditionally plays in epistemology are strongly analogous to that of perception, and barring specific arguments to the contrary, we should treat rational intuition as a source of prima facie justified beliefs. There are two main arguments against the intuition-perception analogy that I will consider and find lacking. First is that while we do use perceptions as evidence to believe certain propositions, in fact no one ever does use intuition evidentially. The second argument, stemming from experimental philosophy, grants that philosophers do use intuitions evidentially, but this practice is fatally unlike that of perception, in that perception yields warranted beliefs and intuition does not.

Fathers do not have an absolute obligation to provide for the welfare of their children. If mothers have the right to opt out of future duties towards their children by deciding to have an abortion instead, fathers too should be considered to have the right to avoid similar future duties. I also argue that fathers should be granted a mechanism by which they can exercise such a right. The discussion is initially motivated by showing an apparent inconsistency among three widely accepted principles regarding a woman's right to an abortion, equality, and parental obligations. I argue that by allowing fathers (with certain restrictions) to refuse to support their forthcoming progeny, the inconsistency among the three principles is resolved. I also argue that this is the best resolution, and provide three other independent arguments in favor of a paternal right of refusal.

In the present paper, I offer a new argument to show that presentism about time is incompatible with time travel. Time travel requires leaving the present, which, under presentism, contains all of reality. Therefore to leave the present moment is to leave reality entirely; i.e. to go out of existence. Presentist “time travel” is therefore best seen as a form of suicide, not as a mode of transportation. Eternalists about time do not face the same difficulty, and time travel is compossible with eternalism.

Several prominent philosophers, including A.J. Ayer and Derek Parfit, have offered the evidentiary requirements for believing human personality can reincarnate, and hence that Cartesian dualism is true. At least one philosopher, Robert Almeder, has argued that there are actual cases which satisfy these requirements. I argue in this paper that even if we grant the empirical data-a large concession-belief in reincarnation is still unjustified. The problem is that without a theoretical account of the alleged cases of reincarnation, the empirical evidence alone does not license giving up materialist theories of the mind.

We argue that Nietzsche's interest in truth is more than merely a critical one. He criticizes one historically prominent conception of truth while proposing his own theory, called "perspectivism". However, Nietzsche's truth perspectivism appears to face a self-referential paradox, which is explored in detail. We argue that no commentator has yet solved this puzzle, and then provide our own solution. This solution, which depends upon distinguishing between weak and strong perspectivism while promoting the former, supplies Nietzsche with a consistent truth theory that preserves the bulk of his claims.

The grand and sweeping claims of many relativists might seem to amount to the argument that everything is relative--except the thesis of relativism. In this book, Steven Hales defends relativism, but in a more circumscribed form that applies specifically to philosophical propositions. His claim is that philosophical propositions are relatively true--true in some perspectives and false in others. Hales defends this argument first by examining rational intuition as the method by which philosophers come to have the beliefs they do. Analytic rationalism, he claims, has a foundational reliance on rational intuition as a method of acquiring basic beliefs. He then argues that there are other methods that people use to gain beliefs about philosophical topics that are strikingly analogous to rational intuition and examines two of these: Christian revelation and the ritual use of hallucinogens. Hales argues that rational intuition is not epistemically superior to either of these alternative methods. There are only three possible outcomes: we have no philosophical knowledge ; there are no philosophical propositions ; or there are knowable philosophical propositions, but our knowledge of them is relative to doxastic perspective. Hales defends relativism against the charge that it is self-refuting and answers a variety of objections to this account of relativism. Finally, he examines the most sweeping objection to relativism: that philosophical propositions are not merely relatively true, because there are no philosophical propositions--all propositions are ultimately empirical, as the naturalists contend. Hales's somewhat disturbing conclusion--that intuition-driven philosophy does produce knowledge, but not absolute knowledge--is sure to inspire debate among philosophers.
