Hanfling shows in this introduction to Ayer's work how he turned this philosophy into a form of British empiricism in the tradition of Hume. According to Ayer, philosophy is an activity of analysts. Metaphysical truths can be neither established nor refuted by philosophical they are meaningless. In support of this claim, he deployed his 'principle of verifiability'. But he found it difficult to refine the principle 'in such a way as to find a middle ground between [an] over-strict requirement' which would disqualify perfectly ordinary statements as meaningless, and 'the over-indulgent licensing of gibberish' - including that of metaphysics.
