In the fall term of 1933-34 I was on my family farm in Maine.
I'm sure Church got some of his ideas from this trip to Europe.
I read one or two other books which gave me a background in mathematics other than logic.
I went to Princeton in the fall of 1930 as a half-time instructor.
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.
It wasn't until my second year that I got to actually work with Church.
