Let us consider, first, the need for a tough mind, characterized by incisive thinking, realistic appraisal, and decisive judgment. The tough mind is sharp and penetrating, breaking through the crust of legends and myths and sifting the true from the false.

I believe in everything until it's disproved. So I believe in fairies, the myths, dragons. It all exists, even if it's in your mind. Who's to say that dreams and nightmares aren't as real as the here and now?

The false can never grow into truth by growing in power.

Very often, all the activity of the human mind is directed not in revealing the truth, but in hiding the truth.

The truth must be told, and I say that those who are seeking to make it appear that anyone who opposes the war in Vietnam is a fool or a traitor or an enemy of our soldiers is a person that has taken a stand against the best in our tradition.

As long as the mind is enslaved, the body can never be free. Psychological freedom, a firm sense of self-esteem, is the most powerful weapon against the long night of physical slavery.
