When a man tells you that he knows the exact truth about anything you are safe in inferring that he is an inexact man.

He will see himself and life and the world as truly as our human limitations will permit; realizing the brevity and minuteness of human life, he will realize also that in individual minds is concentrated whatever of value the known universe contains. And he will see that the man whose mind mirrors the world becomes in a sense as great as the world. In emancipation from the fears that beset the slave of circumstance he will experience a profound joy, and through all the vicissitudes of his outward life he will remain in the depths of his being a happy man.

To create a healthy philosophy you should renounce metaphysics but be a good mathematician.

The experience of overcoming fear is extraordinarily delightful.
