Sleep is often the only occasion in which man cannot silence his conscience; we forget what we knew in our dream.

Both dreams and myths are important communications from ourselves to ourselves.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

Man today is fascinated by the possibility of buying, more, better, and especially, new things. He is consumption hungry... To buy the latest gadget, the latest model of anything that is on the market, is the dream of everybody, in comparison to which the real pleasure in use is quite secondary.

Happiness is a very proud word of our whole cultural heritage.
