As mentioned before, logical positivism is a school of thought has had profound impact on me as a philosopher, in particular the views that were expressed by A.J. Ayer in his book Language, Truth & Logic, which is one of my favorite books of philosophy. In particular, the doctrines of verificationism and emotovism as Ayer enunciated them in the book are ones that I accept and find very important to doing philosophy carefully and clearly. One must reverence the natural sciences and evolve their philosophy alongside it if the philosophy is to be meaningful because philosophy is the handmaiden of science.
In this interview Ayer sits down with Bryan Magee and discusses the central doctrines of logical positivism, and where the defects in the theory were. He also at the end defends what he still thought was useful and true of the movement as a whole.
