This is about the rights and wrongs of bringing people into existence. In a nutshell: sometimes what matters is not what would have happened to you, but what would have happened to the person who would have been in your position, even if that person never actually exists.
Caspar Hare makes an original and compelling case for "egocentric presentism," a view about the nature of first-person experience, about what happens when we see things from our own particular point of view. A natural thought about our first-person experience is that "all and only the things of which I am aware are present to me." Hare, however, goes one step further and claims, counterintuitively, that the thought should instead be that "all and only the things of which I am (...) aware are present." There is, in other words, something unique about me and the things of which I am aware. On Myself and Other, Less Important Subjects represents a new take on an old view, known as solipsism, which maintains that people's experiences give them grounds for believing that they have a special, distinguished place in the world--for example, believing that only they exist or that other people do not have conscious minds like their own. Few contemporary thinkers have taken solipsism seriously. But Hare maintains that the version of solipsism he argues for is in indeed defensible, and that it is uniquely capable of resolving some seemingly intractable philosophical problems--both in metaphysics and ethics--concerning personal identity over time, as well as the tension between self-interest and the greater good. This formidable and tightly argued defense of a seemingly absurd view is certain to provoke debate. (shrink)
Caspar Hare presents a bold and original approach to questions of what we ought to do, and why we ought to do it. He breaks with tradition to argue that we can tackle difficult problems in normative ethics by starting with a principle that is humble and uncontroversial. Being moral involves wanting particular other people to be better off.
In this dissertation I spell out, and make a case for, egocentric presentism, a view about what it is for a thing to be me. I argue that there are benefits associated with adopting this view. ;The chief benefit comes in the sphere of ethics. Many of us, when we think about what to do, feel a particular kind of ambivalence. On the one hand we are moved by an impartial concern for the greater good. We feel the force of (...) considerations of the form: 'all things considered, doing...will make things better overall'. On the other hand we are selfish. We feel the force of considerations of the form 'doing...will make things better for me.' And it appears as if these sorts of considerations often conflict. Often by doing what makes things better for me I do not make things better overall, and vice-versa. But egocentric presentism is capable of resolving this conflict. As an egocentric presentist I can think both that considerations of the greater good always count in favor my doing what's good for me, and that considerations of the greater good always count in favor of other people doing what's good for them. ;Another benefit comes in the sphere of metaphysics. As an egocentric presentist I can make sense of some otherwise perplexing puzzles about personal identity over time, by combining a non-reductionist view about who I will be, with Parfitian reductionism about personal identity over time and a lean physicalist ontology.

Some moral theories tell you, in some situations in which you are interacting with a group of people, to avoid acting in the way that is expectedly best for everybody. This essay argues that such theories are mistaken. Go ahead and do what is expectedly best for everybody. The argument is based on the thought that when interacting with an individual it is fine for you to act in the expected interests of the individual and that many interactions with individuals (...) may compose an interaction with a group.

Should we be time-biased on behalf of other people? 'Sometimes yes, sometimes no'—it is tempting to answer. But this is not right. On pain of irrationality, we cannot be too selective about when we are time-biased on behalf of other people.
On one view of time past, present and future things exist, but their being past, present or future does not consist in their standing in before‐ and after‐relations to other things. So, for example, the event of the signing of the Magna Carta is past, and its being so does not consist in, or reduce to, its coming before the events of 2010.In this paper I discuss arguments for and against this view and view in its near vicinity, perspectival realism. (...) I suggest that perspectival realism is a better view than tense realism. It shares the principal virtues, but not the principal vices, of tense realism. (shrink)

Here's one piece of practical reasoning: "If I do this then a person will reap some benefits and suffer some costs. On balance, the benefits outweigh the costs. So I ought to do it." Here's another: "If I do this then one person will reap some benefits and another will suffer some costs. On balance, the benefits to the one person outweigh the costs to the other. So I ought to do it." Many influential philosophers say that there is something (...) dubious about the second piece of reasoning. They say that it makes sense to trade-off costs and benefits within lives, but not across lives. In this paper I make a case for the second piece of reasoning. My case turns on the existence of morphing sequences—sequences of possible states of affairs across which people transform smoothly into other people. (shrink)
We start by presenting three different views that jointly imply that all people have a large number of conscious beings in their immediate vicinity, and that the number greatly varies from person to person. We then present and assess an argument to the conclusion that how confident people should be in these views should sensitively depend on how massive they happen to be. According to the argument, sometimes irreducibly de se observations can be powerful evidence for or against believing in (...) metaphysical theories. (shrink)
