Life is a language in which certain truths are conveyed to us; if we could learn them in some other way, we should not live.

Life is a constant process of dying.

What a man is contributes much more to his happiness than what he has or how he is regarded by others.

The brain may be regarded as a kind of parasite of the organism, a pensioner, as it were, who dwells with the body.

Knowledge is to certain extent a second existence.

This actual world of what is knowable, in which we are and which is in us, remains both the material and the limit of our consideration.

What disturbs and depresses young people is the hunt for happiness on the firm assumption that it must be met with in life. From this arises constantly deluded hope and so also dissatisfaction. Deceptive images of a vague happiness hover before us in our dreams, and we search in vain for their original. Much would have been gained if, through timely advice and instruction, young people could have had eradicated from their minds the erroneous notion that the world has a great deal to offer them.
