“Without books the development of civilization would have been impossible. They are the engines of change, windows on the world, "Lighthouses" as the poet said "erected in the sea of time." They are companions, teachers, magicians, bankers of the treasures of the mind, Books are humanity in print.”

“Change the way you speak about yourself and you can change your life.”

“No man ever steps in the same river twice, for it's not the same river and he's not the same man.”

“Whosoever wishes to know about the world must learn about it in its particular details. Knowledge is not intelligence. In searching for the truth be ready for the unexpected. Change alone is unchanging. The same road goes both up and down. The beginning of a circle is also its end. Not I, but the world says it: all is one. And yet everything comes in season.”

“Everything flows and nothing abides; everything gives way and nothing stays fixed... Cool things become warm, the warm grows cool; the moist dries, the parched becomes moist... It is in changing that things find repose.”

“Dripping water hollows out stone, not through force but through persistence.”

“All things change, nothing perishes.”
