If you can't prove something, it is literally senseless - so argues Ayer in this irreverent and electrifying book. Statements are either true by definition (as in maths), or can be verified by direct experience. Ayer rejected metaphysical claims about god, the absolute, and objective values as completely nonsensical. Ayer was only 24 when he finished LANGUAGE, TRUTH & LOGIC, yet it shook the foundations of Anglo-American philosophy and made its author notorious. It became a classic text, cleared away the cobwebs in philosophical thinking, and has been enormously influential.
Sir Alfred Ayer caused a furore with the publication of his LANGUAGE, TRUTH & LOGIC in 1936, when he was only 24. From 1959 until 1978 he was Wykeham Professor of Logic at the University of Oxford. He died in 1989. Ben Rogers is the author of A. J.AYER: A LIFE (Chatto & Windus 1999, Vintage 2000).
