It is true that one has to think first and then to act - but it's also true that if one has no possibility of acting, one's thinking kind of becomes empty and stupid.

If you take a salesman, who sells a useless commodity, he feels like a fraud.

In our enthusiasm to dominate nature and to produce more material good - goods - we have transformed means into ends.

The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers.

Man may be defined as the animal that can say ''I,'' that can be aware of himself as a separate entity.

The affirmation of one's own life, happiness, growth and freedom, is rooted in one's capacity to love.

Love is the productive form of relatedness to others and to oneself. It implies responsibility, care, respect. If it isn't productive and respectful, it isn't love, but only fear masquerading as love.
