"Let reason count the stars, weigh the mountains, fathom the depths — the employment becomes her, and the success is glorious. But when the question is, " How shall man be just with God?" reason must be silent, revelation must speak; and he who will not hear it assimilates himself to the first deist, Cain; he may not kill a brother, he certainly destroys himself."
"But all was false and hollow; though his tongue Dropt manna, and could make the worse appear The better reason, to perplex and dash Maturest counsels."
"Subdue By force, who reason for their law refuse, Right reason for their law."
"There is no just cause for apprehending that we shall be misled by the proper exercise of reason on any subject which may be proposed for our consideration. The only danger is of making an improper use of this faculty, which is one of the most common faults to which our nature is liable. Most men profess that they are guided by reason in forming their opinions; but if this were really the case, the world would not be overrun with error; there would not be so many absurd and dangerous opinions propagated and pertinaciously defended."
"Reason may be employed in two ways to establish a point: firstly, for the purpose of furnishing sufficient proof of some principle, as in natural science, where sufficient proof can be brought to show that the movement of the heavens is always of uniform velocity. Reason is employed in another way, not as furnishing a sufficient proof of a principle, but as confirming an already established principle, by showing the congruity of its results, as in astrology the theory of eccentrics and epicycles is considered as established, because thereby the sensible appearances of the heavenly movements can be explained; not, however, as if this proof were sufficient, forasmuch as some other theory might explain them."
"Reason in man is rather like God in the world."
"I think I am justified — though where so many hours have been spent in convincing myself that I am right, is there not some reason to fear I may be wrong?"
"…He is a weak ruler who needs religion to uphold his government; it is as if he would catch his people in a trap. My people are going to learn the principles of democracy, the dictates of truth and the teachings of science. Superstition must go. Let them worship as they will; every man can follow his own conscience, provided it does not interfere with sane reason or bid him against the liberty of his fellow-men."
"I do not leave any verses, dogmas, nor any moulded standard principles as moral heritage. My moral heritage is science and reason. What I have done and intended to do for the Turkish nation lies in that. Anyone willing to appropriate my ideas for themselves after me will be my moral inheritors provided they would approve the guidance of science and reason on this axis."
"Reason is omnivorous; it does not pasture exclusively in scientific fields."
"When he (Thomas Aquinas) wants to represent the activity of our reason in knowledge, he takes the image of the flight of birds and says: there is the bird that flies in a rotating, circular way, or the flight that goes forward and backward or the flight that goes from top to bottom, from bottom to top. Circular motion is contemplative motion, motion that goes forward is from cause to effect, backward is from effect to cause, from top to bottom is deduction, from bottom to top is induction. Remembering the flight of birds recalls all the formalities of cognitive activity."
"Reason is like a runner who doesn't know that the race is over, or, like Penelope, constantly undoing what it creates.... It is better suited to pulling things down than to building them up, and better at discovering what things are not, than what they are."
"Il n'est pas nécessaire de tenir les choses pour en raisonner."
"In the logic of science there is a principle as important as that of parsimony: it is that of sufficient reason. The former directs us to look for simplest causes, the later cautions us not to simplify so far that the explanation is inadequate to the facts to be explained....Parsimony is not itself a simple criterion of a good methodology; we cannot simply count the factors of explanation and say that the theory containing the smallest number is the best. The ideal of parsimony cannot be expressed without the proviso that the conditions for which it is a norm shall themselves be adequate."
"Reason always stands in need of being purified by faith"
"Reason cannot remain a bare intellectual faculty; it must become a faculty of judgment dealing with the question of values."
"RATIONAL, adj. Devoid of all delusions save those of observation, experience and reflection."
"REASON, v.i. To weight probabilities in the scales of desire."
"REASON, n. Propensitate of prejudice."
"La felicité de l'homme consiste a vivre selon la raison."
"Example has more followers than reason. We unconsciously imitate what pleases us, and insensibly approximate to the characters we most admire. In this way, a generous habit of thought and of action carries with it an incalculable influence."
"If we would guide by the light of reason, we must let our minds be bold."
"Pure Reason left to herself relieth on axioms and essential premises which she can neither question nor resolve."
"We should not in the field of Reason look to find less vary and veer than elsewhere in the flux of Life."
"Reason is Life's sole arbiter, the magic Laby'rinth's single clue: Worlds lie above, beyond its ken; what crosses it can ne'er be true."
"Pagan philosophers set up reason as the sole guide of life, of wisdom and conduct; but Christian philosophy demands of us that we surrender our reason to the Holy Spirit; and this means that we no longer live for ourselves, but that Christ lives and reigns within us (Rom 12:1; Eph 4:23; Gal 2:20)."
"Reason will not lead to solution; I will end up lost in confusion"
"All great men are gifted with intuition. They know without reasoning or analysis, what they need to know."
"A rational, moral being cannot, without infinite wrong, be converted into a mere instrument of others’ gratification. He is necessarily an end, not a means. A mind, in which are sown the seeds of wisdom, disinterestedness, firmness of purpose, and piety, is worth more than all the outward material interests of a world. It exists for itself, for its own perfection, and must not be enslaved to its own or others’ animal wants."
"Man has been endowed with reason, with the power to create, so that he can add to what he's been given. But up to now he hasn't been a creator, only a destroyer. Forests keep disappearing, rivers dry up, wild life's become extinct, the climate's ruined and the land grows poorer and uglier every day."
"Within the brain's most secret cells A certain Lord Chief Justice dwells Of sovereign power, whom one and all With common voice, we Reason call."
"True law is right reason in agreement with nature; it is of universal application, unchanging and everlasting; it summons to duty by its commands, and averts from wrongdoing by its prohibitions."
"To me the entire uselessness of such rules as practical guides lies in the inherent vagueness of the word "reasonable," the absolute impossibility of finding a definite standard, to be expressed in language, for the fairness and the reason of mankind, even of Judges. The reason and fairness of one man is manifestly no rule for the reason and fairness of another, and it is an awkward, but as far as I see, an inevitable consequence of the rule, that in every case where the decision of a Judge is overruled, who does or does not stop a case on the ground that there is, or is not, reasonable evidence for reasonable |men, those who overrule him say, by implication, that in the case before them, the Judge who is overruled is out of the pale of reasonable men."
"Water cannot rise higher than its source, neither can human reason. Now, all reasoning respecting transcendent truths must have its source where the truths or ideas themselves originate."
"Religion passes out of the ken of reason only where the eye of reason has reached its own horizon; faith is then but its continuation, even as the day softens away into the sweet twilight; and twilight, hushed and breathless, steals into the darkness."
"Peace rules the day, where reason rules the mind."
"We think only through the medium of words.—Languages are true analytical methods.—Algebra, which is adapted to its purpose in every species of expression, in the most simple, most exact, and best manner possible, is at the same time a language and an analytical method.—The art of reasoning is nothing more than a language well arranged."
"Reason has built the modern world. It is a precious but also a fragile thing, which can be corroded by apparently harmless irrationality. We must favor verifiable evidence over private feeling. Otherwise we leave ourselves vulnerable to those who would obscure the truth."
"In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice."
"[T]he power of forming a good judgment and of distinguishing the true from the false, which is properly speaking what is called Good sense or Reason, is by nature equal in all men."
"It was not reason that besieged Troy; it was not reason that sent forth the Saracen from the desert to conquer the world; that inspired the crusades; that instituted the monastic orders; it was not reason that produced the Jesuits; above all, it was not reason that created the French Revolution. Man is only great when he acts from the passions; never irresistible but when he appeals to the imagination."
"He, who will not reason, is a bigot; he, who cannot, is a fool; and he, who dares not, is a slave."
"I want now to glance for a moment at the development of the theoretical method, and while doing so especially to observe the relation of pure theory to the totality of the data of experience. Here is the eternal antithesis of the two inseparable constituents of human knowledge, Experience and Reason, within the sphere of physics. We honour ancient Greece as the cradle of western science. She for the first time created the intellectual miracle of a logical system, the assertions of which followed one from another with such rigor that not one of the demonstrated propositions admitted of the slightest doubt—Euclid's geometry. This marvellous accomplishment of reason gave to the human spirit the confidence it needed for its future achievements. ...But yet the time was not ripe for a science that could comprehend reality, was not ripe until a second elementary truth had been realized, which only became the common property of philosophers after Kepler and Galileo. Pure logical thinking can give us no knowledge whatsoever of the world of experience; all knowledge about reality begins with experience and terminates in it."
"Two angels guide The path of man, both aged and yet young, As angels are, ripening through endless years, On one he leans: some call her Memory, And some Tradition; and her voice is sweet, With deep mysterious accords: the other, Floating above, holds down a lamp which streams A light divine and searching on the earth, Compelling eyes and footsteps. Memory yields, Yet clings with loving check, and shines anew, Reflecting all the rays of that bright lamp Our angel Reason holds. We had not walked But for Tradition; we walk evermore To higher paths by brightening Reason's lamp."
"Comedy is in act superior to tragedy and humourous reasoning superior to grandiloquent reasoning."
"Knowest thou what kind of speck you art in comparison with the Universe?—That is, with respect to the body; since with respect to Reason, thou art not inferior to the Gods, nor less than they. For the greatness of Reason is not measured by length or height, but by the resolves of the mind. Place then thy happiness in that wherein thou art equal to the Gods."
"One who knows not who he is and to what end he was born; what kind of world this is and with whom he is associated therein; one who cannot distinguish Good and Evil, Beauty and Foulness,... Truth and Falsehood, will never follow Reason in shaping his desires and impulses and repulsions, nor yet in assent, denial, or suspension of judgment; but will in one word go about deaf and blind, thinking himself to be somewhat, when he is in truth of no account. Is there anything new in all this? Is not this ignorance the cause of all the mistakes and mischances of men since the human race began?"
"Study how to give as one that is sick: that thou mayest hereafter give as one that is whole. Fast; drink water only; abstain altogether from desire, that thou mayest hereafter confirm thy desire to Reason."
"A wise man, who puts himself under the government of reason, will be able to receive an injury with calmness, and to treat the person who committed it with lenity; for he will rank injuries among the casual events of life, and will prudently reflect that he can no more stop the natural current of human passions, than he can curb the stormy winds."
"Auctoritas siquidem ex vera ratione processit, ratio vero nequaquam ex auctoritate. Omnis enim auctoritas, quae vera ratione non approbatur, infirma videtur esse. Vera autem ratio, quum virtutibus suis rata atque immutabilis munitur, nullius auctoritatis adstipulatione roborari indigent."
