"A short but hugely significant volume which presents a new story about the Vienna Circle at the occasion of its centenary. What also makes it special is the personality of the author: a trained philosopher and scientist with a good historical vein, who learnt many of his perspectives from students of the leading logical empiricists. It is a well-written, comprehensive book with an engaging narrative." - Adam Tamas Tuboly, Hungarian Academy of Sciences"The best, short account of the history and broader significance of the Vienna Circle." - Jordi Cat, Indiana University, USA
