Having just finished Peter Berger's Adventures of an Accidental Sociologist, I can only ask, "where do I go to take one of his classes?"
The man is very smart, writes in a plain style, and recounts a remarkable career in which he (Forrest Gump-like?) manages to find himself involved in interesting places and/or timely policy-relevant intellectual pursuits. It's a fascinating trip through the culture and politics of the last 50-60 years.
And the jokes! He likes them and they are all over the book. Here is just one from the section on occupations: "An economist: someone who knows everything -- and nothing else."
Berger can be funny as well as profound with just a few well-chosen words. It's a very short book.
