I have given this essay the title: “The Genealogy of Avenging Spirits” after Nietzsche's treatise: “The Genealogy of Morals” (Zur Genealogie der Moral). In this book Nietzsche clarifies the origins and essence of Christian morality which constitutes the basis of European civilization. In a similar fashion I shall endeavor to point out the origins and essence of the concept of avenging spirits which seems to me to form the basis of Japanese civilization.

It may seem strange to talk about a concept of avenging spirits. Nevertheless Norinaga Motoori considered mono-noawaré (the melancholy quality of things) the essence of Japanese culture; Daisetsu Suzuki, who was influenced by Zen, related its essence to a conception of Nothingness; and Ruth Benedict related it to the concept of shame as opposed to that of crime. I do not feel that these different opinions which have preceded mine are erroneous, for they undoubtedly capture certain aspects of our culture; however I would venture to say that it is more profoundly influenced by the concept of avenging spirits.
