Bertrand Russell

Bertrand Russell was a British philosopher, logician, mathematician, historian, writer, social critic, political activist and Nobel laureate.

In the early 20th century, Russell led the British “revolt against idealism”. He is considered one of the founders of analytic philosophy, and he is widely held to be one of the 20th century’s premier logicians. His work has had a considerable influence on mathematics, logic, set theory, linguistics, artificial intelligence, cognitive science, computer science (see type theory and type system), and philosophy, especially the philosophy of language, epistemology, and metaphysics.
