In this quite modestly ambitious essay, I'll generally just assume that, for the most part, our "scientifically informed" commonsense view of the world is true. Just as it is with such unthinking things as planets, plates and, I suppose, plants, too, so it also is with all earthly thinking beings, from people to pigs and pigeons; each occupies a region of space, however large or small, in which all are spatially related to each other. Or, at least, so it is (...) with the bodies of these beings. And, even as each of these ordinary entities extends through some space, so, also, each endures through some time. In line with that, each ordinary entity is at least very largely, and is perhaps entirely, an enduring physical entity (which allows that many might have certain properties that aren't purely physical properties.) Further, each ordinary enduring entity is a physically complex entity: Not only is each composed of parts, but many of these parts, whether or not absolutely all of them, are themselves enduring physical entities, and many of them also are such physically complex continuing entities. When an ordinary entity undergoes a significant change, then, at least generally, this change will involve changes concerning that entity's constituting physical parts, whether it be a rearrangement of (some of) these parts, or a loss of parts, or a gain of parts, or whatever. Often, the entity will still exist even after the change occurs. As we may well suppose, this happens when, from two strokes of an ax, an ordinary log loses just a chip of wood. As we may then say, such a change conforms with the log's "persistence conditions." Somewhat less often, such an ordinary entity undergoes a change that means an end to it: When a bomb's explosion makes our log become just so many widely scattered motes of dust, the log will no longer exist. Such a momentous change doesn't conform with the log's persistence conditions. (shrink)

It’s been agreed for decades that not only does Determinism pose a big problem for our choosing from available alternatives, but its denial seems to pose a bit of a problem, too. It’s argued here that only Determinism, and not its denial, means no real choice for us.But, what explains the appeal of the thought that, where things aren’t fully determined, to that extent they’re just a matter of chance? It's the dominance of metaphysical suppositions that, together, comprise Scientiphicalism: Wholly (...) composed of such mindless physical parts as electrons, you are a being whose powers are all physical powers, physically deriving from the powers of your parts and their physical arrangements. Scientiphicalisrn conflicts with your having real choice.Some fairly conservative alternatives to Scientiphicalism may allow for choice. Two are briefly discussed: On the further-fetched, you are a Cartesian mental being, a nonphysical being in powerful interaction with physical things. On the more conservative approach, you are wholly composed of physical parts, but some of your powers are radically emergent, including your power to choose.Finally, it’s argued that, if you choose, you must be, to some extent, exempt from natural laws.

Peter Unger’s book has both substantive and methodological aims. Substantively, it aims to prove the following four claims in the following order: we must, in general, suffer great losses of property to prevent suffering and death; we may, in general, impose such losses on others for the same goals; we may, in general, kill others to prevent more deaths; and we must, in general, kill ourself to prevent more deaths. Methodologically, it aims to show that intuitive judgments about cases that (...) would be presented as evidence against the four substantive claims—the standard technique of nonconsequentialists arguing against consequentialists—are worthless because we can construct cases that generate the opposite intuitive judgment; further, we can show that the factors that distinguish the cases yielding such different intuitions are not morally significant; and hence, we must decide which judgments are correct by consulting such general moral values as the importance of reducing suffering and death. Thus, Unger offers an error theory of nonconsequentialist restrictions on harming others and prerogatives not to make large sacrifices to aid. This error theory is based on the psychological effects of morally insignificant factors. (shrink)

This book presents, explains and defend an account of our identity, overtime that is both (a) psychologically aimed and (b) physically based. Not advanced as analytic, or as conceptually true, the account is meant to hold "only relative to the general correctness of our contemporary view of the world". Even so, it is explained why influential contemporary thinkers--Lewis, Nozick, Padfit, Shoemaker and others--have "vastly" underrated the importance of physical continuity to our survival through time.

While well-known for his longer book-length work, philosopher Peter Unger's shorter articles have, until now, been less accessible. Collected in two volumes, Philosophical Papers includes articles spanning over 40 years of Unger's long and fruitful career. Volume two focuses on Unger's important work in metaphysics.
