Hmm. If you prove that it is impossible that something doesn't exist, I may be very tempted to try to find it.

It is in this sense (among others) that I think that classical and constructive mathematics coexist healthly.

You also say: "Looking at you, Axiom of Choice."

In fact, much of my work has been about when you can choose things that classical mathematics say you can do.

You know, people explore ideas in all directions, and I think this is rather healthy.

The point of this thread is (1) understand the differences (rather than join the Classical Team or the Constructive Team), (2) learn from each other, (3) still feel free to join the Team you like.
