“The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice. ... So long as men are not trained to withhold judgment in the absence of evidence, they will be led astray by cocksure prophets, and it is likely that their leaders will be either ignorant fanatics or dishonest charlatans. To endure uncertainty is difficult, but so are most of the other virtues.”
― Bertrand Russell, Unpopular Essays

“In preparing for battle I have always found that plans are useless, but planning is indispensable.”
― Dwight D. Eisenhower

“Anyone who thinks that the Communist regimes of Central Europe are exclusively the work of criminals is overlooking a basic truth: The criminal regimes were made not by criminals but by enthusiasts convinced they had discovered the only road to paradise.

― Milan Kundera, The Unbearable Lightness of Being

“I can never read all the books I want; I can never be all the people I want and live all the lives I want. I can never train myself in all the skills I want. And why do I want? I want to live and feel all the shades, tones and variations of mental and physical experience possible in my life. And I am horribly limited.”
― Sylvia Plath, The Unabridged Journals of Sylvia Plath
