Abstract

Whitehead and Russell, with names gloriously coupled in their "Principia Mathematica", parted ways during World War I.  My explication contrasts an Anglican loyal to his nation's will to win the 1914-18 war, to a Puritan protest against the evils of that war and a desire to save society from dire consequences.  Russell's Cassandra prophecies were not welcome in his university, any more than in his nation.  Yet the grounds of his dismissal from Trinity College did not satisfy his older colleague.  Whitehead was unable to justify Bertie's "heedlessness."  the parting of the ways was ideological more than the division between analytic philosophy and metaphysics, and my "Bertrand Russell" stresses the metaphysical side of Russell's work as well as his personal moral calling ("thou shalt not follow a multitude to do evil").  Philosophy lost the blending of analytic clarity with metaphysical profundity.  We can only speculate what the continued collaboration might have yielded.  [Abstract from The Philosopher's Index]
