What I refer to here as the dilemma of authority arises when one ought to defer to authority; one ought to act as the more weighty reason demands; one can do either; one cannot do both. For those who reject the possibility of legitimate authority, the dilemma does not arise. Among those who accept legitimate authority, some, including Joseph Raz, presume the conflict can be resolved without remainder. In this paper, I argue that, in a moral conflict of this kind, when one of the reasons for action is defeated but not cancelled, it is rational to feel regret for failing to do what one ought to do.

This contribution examines Miscevic’s defence against restrictionist X-phi, based on his view that thought experiments exhibit a large number of typical stages. On Miscevic’s view, the epistemic threats identified by proponents of the negative program in X-phi may be countered or ameliorated in various ways at various stages. I argue that the defence he offers is insufficient to counter the arguments by in particular Machery.

Are our rights—to our bodily integrity, to our possessions, to the goods and services promised us, and so on—matters of fact, or are our rights functions of others’ beliefs about how their acts will affect our rights? The conventional view states that subjective oughts—based on what we believe—determine culpability, whereas objective oughts—based on the facts—determine permissibility. After all, the idea that our beliefs about how our acts would affect others’ rights might affect the contours of those rights themselves appears deeply paradoxical. For how can others’ rights be based on our beliefs when those beliefs have as their objects not themselves but others’ rights? Nonetheless, paradoxical as that position may appear, a strong case can be mounted in its defense, not by focusing on the rights themselves, but by focusing on the acts that imperil those rights. It is the burden of this essay to make a case for the belief-relativity rather than the fact-relativity of rights.

Many have argued that human enhancement, in particular bioenhancement via genetic engineering, brain-interventions or preimplantation embryo selection, is problematic even if it can be safely implemented. Various arguments have been put forward focusing on issues such as the undermining of autonomy, uneven distribution and unfairness, and the alteration of one’s identity, amongst others. Nevertheless, few, if any, of these thinkers oppose vaccines. In what follows, I argue for the permissibility of a limited set of cognitive enhancements – in particular, the enhancement of evaluative judgment and self-control – by analogy with the permissibility of vaccines. As a result, it follows that if one accepts the permissibility of vaccines one will also, other things being equal, be committed to the permissibility of these enhancements. I then consider and respond to a number of possible objections in order to defend and clarify my position.

By playing a crucial role in settling open issues in the philosophical debate about logical consequence, logical evidence has become the holy grail of inquirers investigating the domain of logic. However, despite its indispensable role in this endeavor, logical evidence has retained an aura of mystery. Indeed, there seems to be a great disharmony in conceiving the correct nature and scope of logical evidence among philosophers. In this paper, I examine four widespread conceptions of logical evidence to argue that all should be reconsidered. First, I argue that logical apriorists are more tolerant of logical evidence than empiricists. Second, I argue that evidence for logic should not be read out of natural language. Third, I argue that if logical intuitions are to count as logical evidence, then their evidential content must not be propositional. Finally, I argue that the empiricist proposal of treating experts' judgments as evidence suffers from the same problems as the rationalist conception.

Is understanding subject to a factivity constraint? That is, must the agent’s representation of some subject matter be accurate in order for her to understand that subject matter? ‘No’, I argue in this paper. As an alternative, I formulate a novel manipulationist account of understanding. Rather than correctly representing, understanding, on this account, is a matter of being able to manipulate a representation of the world to satisfy contextually salient interests. This account of understanding is preferable to factivism, I argue, mainly for simplicity reasons. While it explains the intuitive data about understanding as successfully as factivist accounts, it is simpler by virtue of reducing the value truth bestows on understanding to that of usability.

I examine the concept of granting for the sake of the argument in the context of explanatory reasoning. I discuss a situation where S wishes to argue for H1 as a true explanation of evidence E and also decides to grant, for the sake of the argument, that H2 is an explanation of E. S must then argue that H1 and H2 jointly explain E. When H1 and H2 compete for the force of E, it is usually a bad idea for S to grant H2 for the sake of the argument. If H1 and H2 are not positively dependent otherwise, there is a key argumentative move that he will have to make anyway in order to retain a place at the table for H1 at all—namely, arguing that the probability of E given H2 alone is low. Some philosophers of religion have suggested that S can grant that science has successfully provided natural explanations for entities previously ascribed to God, while not admitting that theism has lost any probability. This move involves saying that the scientific explanations themselves are dependent on God. I argue that this “granting” move is not an obvious success and that the theist who grants these scientific successes may have to grant that theism has lost probability.
