@igm,
Quote:@Olivier5,
Duration has to endure... if you can't prove duration then you can't prove existence because to say that something exists but it doesn't last for any time whatsoever is a contradiction.. to me anyway.
I postulate the existence of duration (aka time?), but I can't prove it. Nobody can, IMHO. But I would agree that the very notion of existence implies a duration, however short.

Do you agree?
I agree that phenomena cannot be doubted, except in certain, well known-circumtances such as dreams, hybriation, shock, etc.
Though one could say even a dream exists, at the perception level, the referent is not the usual one. A man in a dream can represent more than just a man. He can "code" for your father or some body else dear to you, for instance, so one can say dreams refer to something, but not in the usual way which implies being awake and aware of one's
real environment, including one's
real father.
