A central question, if not the central question, of philosophy of perception is whether sensory states have a nature similar to thoughts about the world, whether they are essentially representational. According to the content view, at least some of our sensory states are, at their core, representations with contents that are either accurate or inaccurate. Tyler Burge’s Origins of Objectivity is the most sustained and sophisticated defense of the content view to date. His defense of the view is problematic in (...) several ways. The most significant problem is that his approach does not sit well with mainstream perceptual psychology. (shrink)

According to the Standard View, a doctor who withdraws life-sustaining treatment does not kill the patient but rather allows the patient to die—an important distinction, according to some. I argue that killing can be understood in either of two ways, and given the relevant understanding, the Standard View is insulated from typical criticisms. I conclude by noting several problems for the Standard View that remain to be fully addressed.

A common objection to representationalism is that a representationalist view of phenomenal character cannot accommodate the effects that shifts in covert attention have on visual phenomenology: covert attention can make items more visually prominent than they would otherwise be without altering the content of visual experience. Recent empirical work on attention casts doubt on previous attempts to advance this type of objection to representationalism and it also points the way to an alternative development of the objection.

Many believe that intended harms are more difficult to justify than are harms that result as a foreseen side effect of one's conduct. We describe cases of harming in which the harm is not intended, yet the harmful act nevertheless runs afoul of the intuitive moral constraint that governs intended harms. We note that these cases provide new and improved counterexamples to the so-called Simple View, according to which intentionally phi-ing requires intending to phi. We then give a new theory (...) of the moral relevance of intention. This theory yields the traditional constraint on intending harm as a special case, along with several stronger demands. (shrink)

ABSENCE is the claim that, if a symbol appears on a map, then absence of the symbol from some map coordinate signifies absence of the corresponding property from the corresponding location. This claim is highly intuitive and widely endorsed. And if it is true, then cartographic representation is strikingly different from linguistic representation. I argue, however, that ABSENCE is false of various maps and that we have no reason to believe it is true of any maps. The intuition to the (...) contrary results from mistaking what a map simply conveys for what it literally represents. (shrink)

Lethal organ donation is a hypothetical procedure in which vital organs are removed from living donors, resulting in their death. An important objection to lethal organ donation is that it would infringe the prohibition on doctors intentionally causing the death of patients. I present a series of arguments intended to undermine this objection. In a case of lethal organ donation, the donor’s death is merely foreseen, and not intended.

It is widely believed to be permissible for a physician to discontinue any treatment upon the request of a competent patient. Many also believe it is never permissible for a physician to intentionally kill a patient. I argue that the prospect of deactivating a patient’s artificial heart presents us with a dilemma: either the first belief just mentioned is false or the second one is. Whichever horn of the dilemma we choose has significant implications for contemporary medical ethics.

DETERMINACY is the claim that covert shifts in visual attention sometimes affect the determinacy of visual content (capital letters will distinguish the claim from the familiar word, 'determinacy'). Representationalism is the claim that visual phenomenology supervenes on visual representational content. Both claims are popular among contemporary philosophers of mind, and DETERMINACY has been employed in defense of representationalism. I claim that existing arguments in favor of DETERMINACY are inconclusive. As a result, DETERMINACY-based arguments in support of representationalism are not strong (...) ones. (shrink)

It is standardly believed that the only way to justify an assertion in the face of a challenge is by making another assertion. Call this claim ASSERTIONS ONLY. Besides its intrinsic interest, ASSERTIONS ONLY is relevant to deciding between competing views of the norms that govern reasoned discourse. ASSERTIONS ONLY is also a crucial part of the motivation for infinitism and Pyrrhonian skepticism. I suggest that ASSERTIONS ONLY is false: I can justify an assertion by drawing attention to something that (...) clearly makes the assertion true, or likely true. (shrink)

Rachael Briggs and Daniel Nolan attempt to improve on Nozick’s tracking theory of knowledge by providing a modified, dispositional tracking theory. The dispositional theory, however, faces more problems than those previously noted by John Turri. First, it is not simply that satisfaction of the theory’s conditions is unnecessary for knowledge – it is insufficient as well. Second, in one important respect, the dispositional theory is a step backwards relative to the original tracking theory: the original but not the dispositional theory (...) can avoid Gettier-style counterexamples. Future attempts to improve the tracking theory would be wise to bear these problems in mind. (shrink)
