I have actually read that book, but many, many, many years ago. If I remember correctly, and the odds on that are evens at best -- I spent more time studying Captain Beefheart than the Vienna School -- it is not concerned with the logic of language but logical positivism, i.e. a statement cannot be true unless it can be verified by observation or logical deduction. This school of thought has been poo-pooed over the years and towards the end of his life Ayers himself said it was "absolute cobblers" (there's a little exercise in logical positivism for you). @Rocky will no doubt be along soon to correct my memory.Start here:
Enjoy the read.
