Bertrand Russell (1872-1970) lived most of his life in the twentieth century and personally witnessed the ferocity and agony of the two world wars. He has also been a witness to the great industrial progress of his time made by the machines. It is therefore natural that he takes up the question of the cause of these wars and comes to attack the machines which are intensely hated. Russell is prominently noted for his anti-war and anti-nuclear campaign.
Bertrand Russell is a controversial writer. He has written on a number of subjects which include, apart from science and humanities, history, political theory, religion and education. He has made important contribution to philosophy and logic.
Some of his principal works are The Principles of Mathematics (1903) and Principia Mathematica which he wrote with Whitehead (1909). In 1950 he was awarded the Nobel Prize for Literature.
