Quotes about reason

The qualities most useful to ourselves are, first of all, superior reason and understanding, by which we are capable of discerning the remote consequences of all our actions, and of foreseeing the advantage or detriment which is likely to result from them: and secondly, self-command, by which we are enabled to abstain from present pleasure or to endure present pain, in order to obtain a greater pleasure or to avoid a greater pain in some future time. In the union of those two qualities consists the virtue of prudence, of all the virtues that which is most useful to the individual

In no victory do they glory so much as in that which is gained by dexterity and good conduct without bloodshed. In such cases they appoint public triumphs, and erect trophies to the honour of those who have succeeded; for then do they reckon that a man acts suitably to his nature, when he conquers his enemy in such a way as that no other creature but a man could be capable of, and that is by the strength of his understanding. Bears, lions, boars, wolves, and dogs, and all other animals, employ their bodily force one against another, in which, as many of them are superior to men, both in strength and fierceness, so they are all subdued by his reason and understanding.

I think that you are immune to the temptations of religion. If you are not, I cannot help you, any more than I could keep you from acquiring a drug habit. A religion is sometimes a source of happiness and I would not deprive anyone of happiness. But it is a comfort appropriate for the weak, not for the strong—and you are strong. The great trouble with religion—any religion—is that a religionist, having accepted certain propositions by faith, cannot thereafter judge those propositions by evidence. One may bask in at the warm fire of faith or choose to live in the bleak uncertainty of reason—but one cannot have both.

“Common sense?”

“Son, that phrase is self-contradictory. ‘Sense’ is never ‘common.’”

The voice of the intellect is a soft one, but it does not rest until it has gained a hearing. Ultimately, after endlessly repeated rebuffs, it succeeds. This is one of the few points in which it may be optimistic about the future of mankind, but in itself it signifies not a little.

Aillas replied that while King Audry cited several points of technical interest, and used the resources of abstract logic in an adroit manner, he had actually made no connection with reality.

Logic and truth are two very different things, but they often look the same to the mind that’s performing the logic.

It is not easy to fall into any absurdity, unless it be by the length of an account; wherein he may perhaps forget what went before. For all men by nature reason alike, and well, when they have good principles. For who is so stupid as both to mistake in geometry, and also to persist in it, when another detects his error to him?

By this it appears that reason is not, as sense and memory, born with us; nor gotten by experience only, as prudence is; but attained by industry: first in apt imposing of names; and secondly by getting a good and orderly method in proceeding from the elements, which are names, to assertions made by connexion of one of them to another; and so to syllogisms, which are the connexions of one assertion to another, till we come to a knowledge of all the consequences of names appertaining to the subject in hand; and that is it, men call science. And whereas sense and memory are but knowledge of fact, which is a thing past and irrevocable, science is the knowledge of consequences, and dependence of one fact upon another; by which, out of that we can presently do, we know how to do something else when we will, or the like, another time: because when we see how anything comes about, upon what causes, and by what manner; when the like causes come into our power, we see how to make it produce the like effects.

Children therefore are not endued with reason at all, till they have attained the use of speech, but are called reasonable creatures for the possibility apparent of having the use of reason in time to come.

You are pooped and demoralized. Why wouldn't you be? Of course it is exhausting, having to reason all the time in a universe which wasn't meant to be reasonable.

[B]ecoming more rational, or not feeling the emotions of social slights, is not part of the human race... not with our current biology. There is no solace to be found from reasoning...

[W]e like to emit logical and rational ideas but we do not enjoy this execution.

[I]f you want to reason about faith, and offer a reasoned (and reason-responsive) defense of faith as an extra category of belief worthy of special consideration, I'm eager to [participate]. I certainly grant the existence of the phenomenon of faith; what I want to see is a reasoned ground for taking faith as a way of getting to the truth, and not, say, just as a way people comfort themselves and each other (a worthy function that I do take seriously). But you must not expect me to go along with your defense of faith as a path to truth if at any point you appeal to the very dispensation you are supposedly trying to justify. Before you appeal to faith when reason has you backed into a corner, think about whether you really want to abandon reason when reason is on your side. You are sightseeing with a loved one in a foreign land, and your loved one is brutally murdered in front of your eyes. At the trial it turns out that in this land friends of the accused may be called as witnesses for the defense, testifying about their faith in his innocence. You watch the parade of his moist-eyed friends, obviously sincere, proudly proclaiming their undying faith in the innocence of the man you saw commit the terrible deed. The judge listens intently and respectfully, obviously more moved by this outpouring than by all the evidence presented by the prosecution. Is this not a nightmare? Would you be willing to live in such a land? Or would you be willing to be operated on by a surgeon you tells you that whenever a little voice in him tells him to disregard his medical training, he listens to the little voice? I know it passes in polite company to let people have it both ways, and under most circumstances I wholeheartedly cooperate with this benign agreement. But we're seriously trying to get at the truth here, and if you think that this common but unspoken understanding about faith is anything better than socially useful obfuscation to avoid mutual embarrassment and loss of face, you have either seen much more deeply into the issue that any philosopher ever has (for none has ever come up with a good defense of this) or you are kidding yourself.
