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.

Young people love what is interesting and odd, no matter how true or false it is. More mature minds love what is interesting and odd about truth. Fully mature intellects, finally, love truth, even when it appears plain and simple, boring to the ordinary person; for they have noticed that truth tends to reveal its highest wisdom in the guise of simplicity.

We should consider every day lost on which we have not danced at least once. And we should call every truth false which was not accompanied by at least one laugh.

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?

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

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