Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind.

Only on paper has humanity yet achieved glory, beauty, truth, knowledge, virtue, and abiding love.

What we want is to see the child in pursuit of knowledge, and not knowledge in pursuit of the child.

Compassion is sometimes the fatal capacity for feeling what it is like to live inside somebody else's skin. It is the knowledge that there can never really be any peace and joy for me until there is peace and joy finally for you too.

Knowledge is power.

The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind.

Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.

The modern mind is in complete disarray. Knowledge has stretched itself to the point where neither the world nor our intelligence can find any foot-hold. It is a fact that we are suffering from nihilism.

I think I have a duty as a recovering guy to help, to make my knowledge of what I went through accessible.

A belief in hell and the knowledge that every ambition is doomed to frustration at the hands of a skeleton have never prevented the majority of human beings from behaving as though death were no more than an unfounded rumor.
