“Man becomes man only by his intelligence, but he is man only by his heart.”

“Man was made to lead with his chin; he is worth knowing only with his guard down, his head up and his heart rampant on his sleeve.”

“The intelligent man who is proud of his intelligence is like the condemned man who is proud of his large cell.”

“Only when there is a wilderness can man harmonize his inner being with the wavelengths of the earth. When the earth, its products, its creatures, become his concern, man is caught up in a cause greater than his own life and more meaningful. Only when man loses himself in an endeavor of that magnitude does he walk and live with humanity and reverence.”

“From birth, man carries the weight of gravity on his shoulders. He is bolted to the Earth. But man has only to sink beneath the surface and he is free. Buoyed by water, he can fly in any direction -- up, down, sideways -- by merely flipping his hand. Under water, man becomes an archangel.”

“Man, who thinks he knows everything. But what does man know...Man cares only for himself, in his fear and hate.”
