Sōseki Natsume said this quote

“ According to his thinking, man was not born for a particular purpose. Quite the opposite: a purpose developed only with the birth of an individual. To objectively fabricate a purpose at the outset and to apply it to a human being was to rob him at birth of freedom of action. Hence, purpose was something that the individual had to make for himself. But no one, no matter who, could freely create a purpose. This was because the purpose of one's existence was as good as announced to the universe by the course of that existence itself.Starting from this premise, Daisuke held that one's natural activities constituted one's natural purposes. A man walked because he wanted to. Then walking became his purpose. He thought because he wanted to. Then, thinking became his purpose. Just as to walk or to think for a particular purpose meant the degradation of walking and thinking, so to establish an external purpose and to act to fulfill it meant the degradation of action. Accordingly, those who used the sum of their actions as a means to an end were in effect destroying the purpose of their own existence. ”
