In his early works, we can trace Kobayashi's own Phenomenoligical cognition of "others'. Kobayashi descrived a young man haunted by solipsism in his first novel, and since then he pursued the subject: the way how he frees from solipsism. After several failures, he published A Letter to X, where the protagonist recognizes "others" in his beloved girl.
In the late 1930s, however, the motif of "others" was replaced by motif of "friend" and "Japanese traditions". After the Second World War, he again took up his first important motif of "others" in his critical essay on Dostoevski's Crime and Punishment with referring to God of Cristianity. This means that he finally suceeded in grasping the vague concept of "others".
