A. J. Ayer

Lore & Background

Ayer was born in St John's Wood, London, to Jules Louis Cyprien Ayer and Reine Citroen. His mother was from the Dutch-Jewish family that founded the Citroën car company; his father was a Swiss Calvinist financier. He was educated at Ascham St Vincent's School and Eton College, where he was a King's Scholar and excelled in classics and sports. He won a classics scholarship to Christ Church, Oxford, graduating with a BA with first-class honours. After a period of study with Moritz Schlick and the Vienna Circle over the winter of 1932–1933, he lectured at Christ Church from 1933 to 1940.

During the Second World War, Ayer served as an officer in the Welsh Guards, chiefly in intelligence (Special Operations Executive and MI6). After the war, he became Grote Professor of the Philosophy of Mind and Logic at University College London from 1946 until 1959, then returned to Oxford as Wykeham Professor of Logic at New College until his retirement in 1977/1978. He was knighted in 1970. Ayer was married four times to three women, and had children with his wives and with Hollywood columnist Sheilah Graham Westbrook.

In 1988, Ayer wrote an article describing a near-death experience after his heart stopped for four minutes. He said it slightly weakened his conviction that death would be the end of him, though he continued to hope it would be. He died on 27 June 1989.

Reader's Guide

A. J. Ayer's significance lies primarily in his role as the leading British exponent of logical positivism, a movement that sought to ground philosophy in empirical verification. His first book, *Language, Truth, and Logic* (1936), published when he was 26, made him the *enfant terrible* of British philosophy by arguing that metaphysical statements—including those about God—are meaningless because they cannot be verified. This stance, along with his endorsement of emotivism in ethics, sparked lasting controversy. Ayer's career spanned prestigious academic posts at Oxford and University College London, and he was knighted in 1970. Beyond philosophy, he was a prominent public intellectual: he campaigned in the 1938 Oxford by-election, served as president of the British Humanist Association and the Homosexual Law Reform Society, and engaged in anti-Vietnam War activism. His later years included a widely discussed near-death experience, which he described as slightly weakening his conviction that death is the end. Ayer's legacy endures as a central figure in 20th-century analytic philosophy and a vocal advocate for secular humanism.
