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

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

I had a liberal arts education at Amherst College where I had two majors, mathematics and philosophy.

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

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

I think Veblen had an interest in logic.

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

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

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

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

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

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

Those three years ended with June 1933. At that time I left Princeton, having submitted my Ph.D. thesis.

Well, I think Barkley and I were the only two who were working with Church for a Ph.D.

And what I learned in Church's course. He trained us intensively in his new system, which he was just developing. Two papers were presented. I think the second paper wasn't published until well after the course was finished.

As I say, there was this movement to try to bring philosophers and mathematicians together into an organization where they would talk to each other. An organization wasn't effective unless you had a journal. That's about all I know.

For example, the philosophers who were interested in logic were probably rather logical for mathematicians. But the ASL got us together, so we could talk to each other and publish in the same journal.

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.

When I got to Princeton I made a point of attending the Philosophy Club and listening to the lectures, but I didn't get involved in any discussions in those clubs. I guess after the first year, I dropped that.
