Now for Thomas Szasz. I found a list of quotes from him on "brainyquote.com" and I'd like to share a few. Comments are welcome.

"A child becomes an adult when he realizes that he has a right not only to be right but also to be wrong."

"Clear thinking requires courage rather than intelligence."

"Every act of conscious learning requires the willingness to suffer an injury to one's self-esteem. That is why young children, before they are aware of their own self-importance, learn so easily."

"Happiness is an imaginary condition, formerly attributed by the living to the dead, now usually attributed by adults to children, and by children to adults."
