Why did I love this book?
This is a widely-scorned book whose ideas are no longer in philosophical fashion. But it was the work that first hooked me into philosophy, and I recommend it for its sheer verve and confidence. Freddie Ayer visited Vienna in the 1930s and when he returned to the UK he introduced the ideas of the Vienna Circle into the Anglo-American world. The book argued that propositions that were not testable – for example some assertions about God, or about ethics or aesthetics – were meaningless because they were not verifiable. Amazing claims!
