Bertrand Arthur William Russell, 3rd Earl Russell, (; 18 May 1872 – 2 February 1970) was a British philosopher, logician, mathematician, historian, writer, social critic, political activist, and Nobel laureate. At various points in his life, Russell considered himself a liberal, a socialist and a pacifist, but he also admitted that he had "never been any of these things, in any profound sense." Russell was born in Monmouthshire into one of the most prominent aristocratic families in the United Kingdom.In the early 20th century, Russell led the British "revolt against idealism". He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege, colleague G. E. Moore and protégé Ludwig Wittgenstein. He is widely held to be one of the 20th century's premier logicians. With A. N. Whitehead he wrote Principia Mathematica, an attempt to create a logical basis for mathematics. His philosophical essay "On Denoting" has been considered a "paradigm of philosophy". 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.

It is my intention to make my entire life a rejection of, a protest against the crimes and injustices of war and political tyranny which threaten to destroy the whole race of [humankind] and the world with [it] . . . . I make monastic silence a protest against the lies of politicians, propagandists, and agitators, and when I speak it is to deny that my faith and my church can ever be aligned with these forces of injustice and destruction. But it is true, nevertheless, that the faith in which I believe is also invoked by many who believe in war, believe in racial injustices, believe in self-righteous and lying forms of tyranny. My life must, then, be a protest against these also, and perhaps against these most of all.
Power concedes nothing without demand. It never did, and it never will. Find out just what people will submit to, and you have found out the exact amount of injustice and wrong which will be imposed upon them; and this will continue till they have resisted with either words or blows, or with both. The limits of tyrants are prescribed by the endurance of those whom they suppress.
