“When the search for truth is confused with political advocacy, the pursuit of knowledge is reduced to the quest for power.”

“The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers. ”

“Is science the disinterested pursuit of knowledge which the world may apply if it will? Or is it an activity always dependent upon economic and political demands?”

“Truth is eternal. Knowledge is changeable. It is disastrous to confuse them.”

“I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led.”

“In every age, people are certain that only the things they have deemed valuable have true value. The search for love and the search for wealth are always the two best stories. But while a love story is timeless, the story of a quest for wealth, given enough time, will always seem like the vain pursuit of a mirage.”
