Single Idea 16693

[catalogued under 27. Natural Reality / D. Time / 3. Parts of Time / b. Instants]

Full Idea

Time has parts, some of which have been, others of which are going to be, but no part of it is. The now is not a part, because a part is a measure of the whole, which must be composed of parts. Time, however, does not seem to be composed of nows.

Gist of Idea

Time has parts, but the now is not one of them, and time is not composed of nows


Aristotle (Physics [c.337 BCE], 218a05), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.1

A Reaction

As good an expression as you will ever find of the baffling nature of time. Only the past and the future seem substantial enough to exist. Only the now can be real, and yet it seems to be a nothing. In Phys IV.14 time is mind-dependent.
