I went to Princeton in the fall of 1930 as a half-time instructor.

I think Veblen had an interest in logic.

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

In the fall term of 1933-34 I was on my family farm in Maine.

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

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.
