In 1915, D. H. Lawrence, who had won recognition with his novel Sons and Lovers, met Berfrand Russell, philosopher and mathematician. Both men opposed the war and all it represented, and they intended to voice their philosophy in a series of lectures to he given together in London. II e are indebted to HARRY T. MOORE of the Babson Institute for his skillful editing and elucidation of Lawrence’s unpublished letters to Russetl, twenty-three of which will be published by the Gotham Book Mart this month.
