Aristotle and the law of non-contradiction

[gnosis_within]

aristotle used three ways to show the law of non-contradiction:

1. ontologically-a thing cannot have two opposing attributes at the same time (this does not refer to relational characteristics, such as tall or heavy)

2. linguistically-to say two contrary things in a sentence is really saying nothing at all

3. psychologically-a person cannot believe two contrary things at the same time about the same thing

if #2 and #3 are true, does that mean that #1 is also?

[Aaron Brown]

It depends if the method of language has rules to permit contradictions, or not. For example, we speak english, aristotle didn't. Perhaps if he did, I could tell him, "I'm going to stay here."

And besides, who remembers double-think?

Heck, remember that dead/living cat in the box-example they use for quantum physics?
