Why does causality require the existence of things or time? You are limiting the principle's scope unnecessarily, and actually making it not an essential feature of reality.Cause and effect, even as a principle, cannot exist without things and time.
I feel the logical form "P implies Q, AND not-P implies not-Q" expresses the fundamental truth "there is no effect without a cause" more perfectly than your version.
Leyla,
I don't think cause and effect can be separated at all, and I believe it completely accidental to our language that they are two concepts. They should rightly be one word (causality).I think if you can logically and empirically prove that there can be cause without any effect, then you can prove that the universe (not a particular and limited form of it) is finite.
It is similar to the infinitive form of a verb. English is the only language that I know of where you can split an infinite ("to boldly go...").
Oh my gosh. What a terrible example I used!God damn it. Is there no escaping Her?! :)
