The essays in this little volume, published here for the first time in book form, were written by Bertrand Russell during the Second World War when he was less concerned with the stormy issues of nuclear warfare and the containment of Communist aggression and more with "the art of reckoning" in the fields of mathematics, logic and philosophy.
