Abstract
Baron Dairoku Kikuchi who studied abroad in London and Cambridge from the end of the Tokugawa period to the beginning of the Meiji Era was a closed friend of Professor Karl Pearson. After returning Japan Kikuchi trained mathematics teachers at first in Japan using Clifford’s “Common sense of the exact science” edited by Pearson. Meanwhile, Kinnosuke Natsume who studied in London in the middle of the Meiji Period was inspired by Pearson’s “the Grammar of Science” and aimed to establish literature as science. This presentation introduces their life and ideological exchanges.
