“Momonoshizuku” is an essay which can stipulate Shimazaki Toson's mental world in his later years. Toson, the genius who has altered the literary form by using compressed and concise format on his personal experience, was believed to have made an attempt to narrow the gap between the readers. As many genre merge together, Toson is an Essayist, Humanist, Moralist, and etc showing a variety of colors. I wonder if, according Toson's ideology and philosophy expressed by aphorism, in the readers' point of view it would resemble to be human textbook. I was able to understand that in his self-examination on life, he was focused on the ideology pursued by various essayists from East and West. In 1930, Toson sensed the crisis of human absence as they were buried by sudden changes in the international relations and infiltration of science. Toson presented Shakespeare's human admiration and positive ideology, what he considered to be the norm of Western literature, to be what modern men should be endowed with to those who were in confusion and nervousness. Also, under the belief that civilization's crisis should result from the unbalance between machinery civilization and civilization of mental ethics, it can be said that he had established his determination as a humanist by recollecting Goethe's life, who pursued freedom and the return to nature to love humane things. And Tolstoy's morality on change in unsettlement from a social aspect with accuracy, sincerity, and furthermore good conscience in self-examination had much mutuality to their correspondent parts with Toson, hence, making it unable to deny that Toson is a moralist. Lastly, Toson "simple", which acts as the core to not only life, but also literary form from both Lao-tuz's "leaving nature as it is"as well as its similar reasons of Pascal, which Tolstoy aimed to reach in his later years. Simplicity, which is created from the combination of idea of repair and beauty, was not only Toson guide, but also his life and had settled as his life creed, hence, life philosophy.
