Soseki Natsume left Yokohama for England to study abroad in September 1900 when he was 33 years of age and was awakened to the spirit of “self-centeredness” in London. As a result of this, he was convinced of an independent self as a Japanese man. In other words, he was awakened to his spiritual nature of self-centeredness in contrast to the nature of being others-centered before this time. The issue is what the ``self`` of self-centeredness was or the self when he insisted self-centeredness. On the 13th of September 1912, General Maresuke Nogi commited suiside soon after Emperor Meiji passed away. Undoubtedly, he followed his master to the grave. It can be said that Nogi`s death was his spiritually individual decision. The self of self-centeredness has transcended such a suicide in modern age. In relation to this, Soseki`s “Moho to Dokuritsu (Imitation and Independence)” can be referred. In this article, he insisted that a human being has both an aspect of independence and imitation. He also wrote that the Nogi had committed suicide by his sincerity to his master. Now, let`s look at the meaning of sincerity in such a case. I would like to examine this with reference to Ikutaro Nishida`s “Zen no Kenkyu (An Inquiry into the Good)”. Nishida emphasized that his “sincerity” means “the main body of the space” as “the true self” as well as being sincere. Most of the demand arises from the bottom of an individual based on “God`s will”. It can be understood on this surface. However, I believe that his sincerity is the same as what Natsume defined sincerity as. I, personally, look at the word of “sincerity”. Nogi followed his master to the grave as the result of his internal demand. In such time, self holds the meaning of the main body of the space as Nishida said. Last but not least what I would like to point out is the recognition of metaphysics. This recognition has to be personally subjective because it essentially treats human begins. By this mean, what Nishida insisted also needs to be understood as something individual. It can be said that is the true loneliness of a religious lives.
