“Conflict is the gadfly of thought. It stirs us to observation and memory. It instigates invention. It shocks us out of sheep-like passivity, and sets us at noting and contriving…conflict is a sine qua non of reflection and ingenuity.”

Context: THESE are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands it now, deserves the love and thanks of man and woman. Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as FREEDOM should not be highly rated.

Beast and Man: The Roots of Human Nature (1979).
Context: Do we find ourselves a species naturally free from conflict? We do not. There has not, apparently, been in our evolution a kind of rationalization which might seem a possible solution to problems of conflict--namely, a takeover by some major motive, such as the desire for future pleasure, which would automatically rule out all competing desires. Instead, what has developed is our intelligence. And this in some ways makes matters worse, since it shows us many desirable things that we would not otherwise have thought of, as well as the quite sufficient number we knew about for a start. In compensation, however, it does help us to arbitrate. Rules and principles, standards and ideals emerge as part of a priority system by which we guide ourselves through the jungle. They never make the job easy--desires that we put low on our priority system do not merely vanish--but they make it possible. And it is in working out these concepts more fully, in trying to extend their usefulness, that moral philosophy begins. Were there no conflict, it [moral philosophy] could never have arisen.

Context: The facts of man's history do not fully represent the faculties of his nature as the history of matter represents the qualities of matter. Man, though finite, is indefinitely progressive, continually unfolding the qualities of his nature; his history, therefore, is not the whole book of man, but only the portion thereof which has been opened and publicly read. So the history of man never completely represents his nature; and a law derived merely from the facts of observation by no means describes the normal rule of action which belongs to his nature. The laws of matter are known to us because they are kept; there the ideal and actual are the same; but man has in his nature a rule of conduct higher than what he has come up to, — an ideal of nature which shames his actual of history. Observation and reflection only give us the actual of morals; conscience, by gradual and successive intuition, presents us the ideal of morals.

Context: There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again.
