I don't think Post often came to Princeton during the '30s. I can't remember ever seeing him in Princeton.

Here at Wisconsin we didn't get an undergraduate course in mathematical logic until the '60s.

It wasn't until my second year that I got to actually work with Church.

I had some hesitations about philosophy because, if you worked out a philosophical theory, it was hard to know whether you were going to be able to prove it or whether other theories had just as good a claim on belief.

I went to Princeton from Amherst, where I split my interests between mathematics and philosophy.

I'm sure Church got some of his ideas from this trip to Europe.

I think Veblen had an interest in logic.
