“Stuckness shouldn't be avoided. It's the physic predecessor of all real understanding.”

“It is easy to surpass a predecessor, but difficult to avoid being surpassed by a successor.”

“What in heaven's name was the real essence of this beauty? Was it the precision of nature with its physical laws, or was it nature's mercilessness, ceaselessly resisting man's understanding?”

“The non-violent resistor not only avoids external, physical violence, but he avoids internal violence of spirit. He not only refuses to shoot his opponent, but he refuses to hate him. And he stands with understanding, goodwill at all times.”

“This had been real: real in its flaws and uncertainties, real in its small triumphs, real in its compromises and understanding.”
