Heredity of Taste is Soseki Natsume's only anti-war work. Chronicling the mourning process of a narrator haunted by his friend's death, the story reveals Soseki's attitude to the atrocity of war, specifically to the Russo-Japanese War of 1904-5, and to the personal tragedies and loss of individuality of young men like his hero Kosan, and the sacrifices made by both the living and the dead.
