A. J. Ayer (1910–1989) was a British philosopher famous for popularizing logical positivism. His seminal book 'Language, Truth and Logic' (1936) challenged metaphysics by emphasizing empirical verification. Ayer served as professor at University College London and influenced 20th-century analytic philosophy. He examined ethics, religion, and epistemology, advocating for clarity and logical rigor. Ayer engaged in public debates and was a prominent figure in intellectual circles. Later in his career, he critiqued elements of his earlier views, showing intellectual evolution. His works continue to shape discussions in philosophy of language and science.
