Ayer

Ayer is best remembered for "Language, Truth and Logic" which introduced British and American readers to the logical positivism of the Vienna circle. This introduction to Ayer's work shows how he turned his import into a form of British empiricism in the tradition of Hume.

According to Ayer, philosophy is an activity of analysis, not a means to truth. First principles and metaphysical truths can neither be established or denied byphilosophical enquiry. He tried to prove that verifibility (whether a proposition can be shown to be true or false) was the key principle of philosophical methodology.
