Hearn regarded man as an entity of millions of cells, a composite of multiples of lives carrying out unconsciously the behests of past ages. Man's instincts are but unconscious memories of the instincts of old. Whitman has this idea in his _Song of Myself_, and Buddha taught this idea which Hearn calls "the highest truth ever taught to man," "the secret unity of life." Hearn states the view fully in his remarkable essay on Dust. "All our emotions and thoughts and wishes, however, changing and growing through the varying seasons of life, are only compositions and recompositions of the sensations and ideas and desires of other folk, mostly of dead people.--I an individual,--an individual soul! Nay, I am a population--a population unthinkable for multitude, even by groups of a thousand millions! Generations of generations I am, æons of æons." Or as he states it in another essay, "Ideas of Pre-existence," in _Kokoro_: "It is incontrovertible that in every individual brain is locked up the inherited memory of the absolutely inconceivable multitude of experiences received by all the brains of which it is the descendant." There are similar ideas in Jack London's _Star Rover_. Hearn laid emphasis on the unity of the past and present, a fundamental principle of psychoanalysis. Hearn saw this idea in Buddhism and hence became attached to the philosophy of this creed, and his reconciliation of it with the theory of evolution is no mere idle dream. Leading Buddhist scholars before Hearn saw the similarity between the theory of heredity as taught by evolution and the doctrine of Karma or transmigration of character. This doctrine of Karma explains also that a man has pernicious unconquered evil instincts because he is allied to ancestors who possessed them strongly. Buddhism taught the theory found in evolution and psychoanalysis, that we contain in ourselves every moral tendency and psychic attribute of millions of people and animals from whom we have descended. We are full of shreds of our ancestors' emotions and characteristics which are buried in our unconscious. II
