The British mathematician and logician, born in 1872 and died in 1970 in his work Principia Mathematica, Essay on the Foundations of Geometry and Mathematical Logic on the Theory of Types proved that pure mathematics is based on pure logical premises. From this he deduced that mathematical concepts are purely logical notions. To overcome some contradictions posed by his views, maintained that mathematical propositions were to be replaced by logical propositions that were expressed by quantifiers, which would make it possible to restrict the meaning of signs. This system of ideas was known by the name of logical atomism.
Russell said that asking mankind to rely on nuclear deterrence as a method to prevent a nuclear war was tantamount to suggesting that the way to eternity on a tightrope. From 1958 he was the organizer and principal leader of the movement for the denuclearization in the United Kingdom.
Since before the First World War, Russell was a pacifist. It also held advanced positions in education and morals. That made him lose his professorship at Cambridge and he was sentenced to prison. But in 1944 returned to teaching and in 1950, won the Nobel Prize for Literature.
