Regarding the former, consider the example you gave for 2 (vagueness in the moment of an animal's death) in more detail. There will be senses in which the animal is a bit alive, and senses in which it is dead. So there are all these different ways in which the animal can be said to be alive, or to exist.<br /><br />The general principle is that to exist is to exist as one of a kind, and that the vagueness comes from the variety of possible kinds. So if we specify our terms more precisely, the vagueness goes away. The vagueness is not really there, it is an illusion caused by the imperfections of our languages. So there is not really vagueness about existence at a time (except insofar as there can be vagueness about existence simpliciter).<br /><br />There would, if I'm right, be no vagueness about our existence at any time, because we are real individuals, not aggregates of molecules that conveniently take various names at various times, and because Presentism is true. Were 4-dimensionalism true, and were spatial vagueness about existence possible (not just the existence of spatially fuzzy things, presumably) then you would be right.Martin Cookehttps://www.blogger.com/profile/11425491938517935179noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-22929695061347876832009-09-16T10:31:19.991-05:002009-09-16T10:31:19.991-05:00The problem, though, is that some of the reasons f...The problem, though, is that some of the reasons for thinking there can be vagueness in respect of temporal location are also reasons for thinking there can be vagueness in respect of existence. But my argument requires that there be vagueness in respect of temporal location but not in respect of existence. And presentists probably are going to bristle at spatial analogies. :-(Alexander R Prusshttps://www.blogger.com/profile/05989277655934827117noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-79101834391433754762009-09-16T09:37:33.444-05:002009-09-16T09:37:33.444-05:00There can be vagueness about existence at a time.
...<i>There can be vagueness about existence at a time.</i><br /><br />Grant that it is not vague whether x exists or not, and grant that x exists. The open question is whether it is indeterminate that x is at t (for some time t). Certainly there is vagueness with respect to spatial location. So, presumably there can be vagueness with respect one's frame, and so vagueness wrt whether one is at time t.Mike Almeidahttps://www.blogger.com/profile/12001511002085064198noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-55594711632855947352009-09-16T08:31:42.745-05:002009-09-16T08:31:42.745-05:00I don't know.

For instance, if one has God involved in things coming into existence (he starts sustaining) and in things coming out of existence (he stops sustaining), then there is some reason to think 2 is false.Alexander R Prusshttps://www.blogger.com/profile/05989277655934827117noreply@blogger.comtag:blogger.com,1999:blog-3891434218564545511.post-44416655883855972562009-09-16T07:31:45.006-05:002009-09-16T07:31:45.006-05:00Do you think it's a harder bullet to bite than...Do you think it's a harder bullet to bite than denying 2? That's my initial inclination. (I don't know the vagueness stuff well enough to have more than an inclination.)Jonathan D. Jacobshttps://www.blogger.com/profile/02913077212736834794noreply@blogger.com
