The underlying sickness of human life is an unwillingness to look with open eyes at the condition of the world.

Whenever you do something without asking yourself, "Why am I doing this?"-that is meaningless life... . The "why" of life makes it meaningful... . Only when an answer is given is one living life as a man.

The knowledge that mankind needs is not the way or principle which has an absolute existence, but the particular truths for here and now and for particular individuals. Absolute truth is imaginary, abstract, vague, without evidence, and cannot be demonstrated.
