I have enjoyed some of the writing and audio from Al Turtle a relationship therapist. I get an RSS feed of his updates and today found a link to his favourite books. Great idea!
I found an ebook of A. E. Van Vogt’s The World of Null-A, non-Aristotelian logic in SF form. I see that this is not a one-off in Al’s list! He is into General Semantics – intrigued I went off on a search trail.
