Herbert Feigl was one of the most admirable people I have known. I was fortunate to have him a a friend and as a teacher (he directed my PhD dissertation). He was a very special friend and a very special teacher. To round out what is being said here, I want to share my impressions of him as a teacher and as a person.

I don't think I ever took a course from Herbert; he taught me informally as a thesis director and as a helpful older friend. When he guided me through the writing of my thesis, I was almost unaware fo the teaching he was doing. It is only in recent years that I have come to appreciate how important it was for me.

In comparison with other teachers, Herbert was extremely permissive—the opposite of coercive. For him, nothing was off-limits.
