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 read one or two other books which gave me a background in mathematics other than logic.

The job in Wisconsin was the first genuine offer of an academic job in a university which I received.

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

I think Veblen had an interest in logic.

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

I think that after Church got his Ph.D. he studied in Europe, maybe in the Netherlands, for a year or two.
