27. Natural Reality / D. Time / 1. Nature of Time / a. Absolute time
If all empirical sensation of bodies is removed, space and time are still left [Kant]
     Full Idea: If everything empirical, namely what belongs to sensation, is taken away from the empirical intuition of bodies and their changes (motion), space and time are still left.
     From: Immanuel Kant (Prolegomena to Any Future Metaphysic [1781], 284)
     A reaction: This is an exercise in psychological abstraction, which doesn't sound like good evidence, though it is an interesting claim. Physicists want to hijack this debate, but I like Kant's idea.
27. Natural Reality / D. Time / 3. Parts of Time / a. Beginning of time
It is hard to see how either time or movement could come into existence or be destroyed [Aristotle]
     Full Idea: It is impossible that movement should either come-to-be or be destroyed. The same can be said for time itself, since it is not even possible for there to be an earlier and a later if time does not exist.
     From: Aristotle (Metaphysics [c.324 BCE], 1071b06)
