1911. The problem of life consists in learning how to live. It is like the problem of addition or subtraction to the schoolboy. When mastered, all difficulty vanishes, and the problem has vanished. All the problems of life, whether they be social, political or religious, subsist in ignorance and wrongdoing.

To the wise, all such problems have ceased.
