“First of all, although men have a common destiny, each individual also has to work out his own personal salvation for himself in fear and trembling. We can help one another to find the meaning of life no doubt. But in the last analysis, the individual person is responsible for living his own life and for "finding himself." If he persists in shifting his responsibility to somebody else, he fails to find out the meaning of his own existence. You cannot tell me who I am and I cannot tell you who you are. If you do not know your own identity, who is going to identify you?”
