Vagueness and Identity :: Philosophy Philosophical Papers

Vagueness and IdentityABSTRACT The view that personal individualism croupe be weak holds that there be statements of personal identity which argon neither honest nor false. The view that composition can be vague holds that unities can postulate borderline constituents that is, elements that are neither parts nor non-parts of some larger agreement. The fibre for vague identity is typically made by flair of an financial statement for the vagueness of composition. In this paper, however, I argue that the thesis that composition can be vague is actually incompatible with the thesis of vague identity. The argument for the horror of these two views arises out of a demonstration of the way in which constituency facts (even vague constituency facts) are grounded in the other facts about how a larger unity is configured. Thus, I array that composites that are allegedly vaguely identical are actually different configurations. Hence, the alliance of vague composition with vague i dentity is taken to be all that is needed in order to show that compositional vagueness is indefensible.IIt is some clocks held that, want other things, identity can be vague.But care should be taken about what this means. The study that identity can be vague is best understood as the claim that there can be statements of identity which are indeterminate in truth value. This view gains in attractiveness when the precision of the concept of identity is contrasted with the lack of precision endemic to various criteria of identity. As Sainsbury nones, diachronic artefact identity must surely be governed by principles such as this Replacing some, but not too many, parts of an artifact does not destroy it, but leaves the very same artifact. Such principles are vague. How could the identity relation, which they determine, be precise? Considerations ilk these extend to members of natural kinds like mountains and cows as well. Whats consistent throughout these views is that identity req uires enough of the charm sort of continuity. This reliance on continuity goes for not only the way we re-identify things over time, but for the way we individuate objects at a time as well. So for example, spatio-temporal continuity at least partially explains how it is that at B passageway and 42nd I am standing on the same road I stood on when I was at Broadway and 41st. Since identity deciding conditions like continuity and contiguousness can be weak or hefty or more or less, it appears the vagueness of those concepts has a limiting effect on how precise identity claims can be.
