“Childhood is that time in which we never question the fact that every adult act is not only an autonomous occurrence in the universe, but that it is also filled, packed, overflowing with meaning, whether that meaning works for ill or good, whether the ill or good is or is not comprehended.
Adulthood is that time in which we see that all human actions follow forms, whether well or badly, and it is the perseverance of the forms that is, whether for better or worse, their meaning.
Various cultures make the transition at various ages, which transition period lasts for varying lengths of time, one accomplishing it in a week with careful dances, ancient prayers, and isolate and specified rituals; another, letting it take its own course, offering no help for it, and allowing it to run on frequently for years. But at the center of the changeover there is a period—whether it be a moment’s vision or a year-long suspicion—where the maturing youth sees all adult behavior as merely formal and totally meaningless.”

“Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.”

“All good research-whether for science or for a book-is a form of obsession.”

“To care only for well-being seems to me positively ill-bred. Whether it's good or bad, it is sometimes very pleasant, too, to smash things.”

“It isn't whether you do it well or ill, it's that you do it all.”

“We are all affecting the world every moment, whether we mean to or not. Our actions and states of mind matter, because we are so deeply interconnected with one another.”

“The moral issues with which Marcus struggles would be, as he points out, unchanged whether the universe were mechanical and devoid of meaning or value or ruled by deity or Providence; whether the will were in fact free or determined; whether there were or were not a future life, or any even fugitive rewards and punishments at all.”

“To me this question whether liberty is a good or a bad thing appears as irrational as the question whether fire is a good or a bad thing. It is both good and bad according to time, place, and circumstance, and a complete answer to the question, In what cases is liberty good and in what cases is it bad? would involve not merely a universal history of mankind, but a complete solution of the problems which such a history would offer.”

“Our hearts are not stones. A stone may disintegrate in time and lose its outward form. But hearts never disintegrate. They have no outward form, and whether good or evil, we can always communicate them to one another.”

“We cannot avoid meeting great issues. All that we can determine for ourselves is whether we shall meet them well or ill.”
