30 Quotes on Philosophy and Reason

"Where danger shews it self, apprehension cannot, without stupidity, be wanting; where danger is, sense of danger should be; and so much fear as should keep us awake, and excite our attention, industry, and vigour; but not to disturb the calm use of our reason, nor hinder the execution of what that dictates."

"Every philosophy is complete in itself and, like a genuine work of art, contains the totality. Just as the works of Apelles and Sophocles, if Raphael and Shakespeare had known them, should not have appeared to them as mere preliminary exercises for their own work, but rather as a kindred force of the spirit, so, too reason cannot find in its own earlier forms mere useful preliminary exercises for itself."

— Georg Wilhelm Friedrich Hegel

"There is no vice that doth so cover a man with shame as to be found false and perfidious. And therefore Montaigne saith prettily, when he inquired the reason, why the word of the lie should be such a disgrace, and such an odious charge? Saith he, If it be well weighed, to say that a man lieth, is as much to say, as that he is brave towards God, and a coward towards men. For a lie faces God, and shrinks from man. Surely the wickedness of falsehood, and breach of faith, cannot possibly be so highly expressed, as in that it shall be the last peal, to call the judgments of God upon the generations of men; it being foretold, that when Christ cometh, he shall not find faith upon the earth."

— Francis Bacon

":Would you persuade, speak of Interest, not of Reason."

— Benjamin Franklin

"The soul of man may be divided into two parts; that which has reason in itself, and that which hath not, but is capable of obeying its dictates."

"The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions."

"I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forgo their use and by some other means to give us knowledge which we can attain by them."

— Galileo Galilei

"What is now decisive against Christianity is our taste, no longer our reasons."

— Friedrich Nietzsche

"He who is a philosopher or lover of learning, and is entirely pure at departing, is alone permitted to reach the gods. And this is the reason, Simmias and Cebes, why the true votaries of philosophy abstain from all fleshly lusts, and endure and refuse to give themselves up to them—not because they fear poverty or ruin of their families, like the lovers of money, and the world in general; nor like the lovers of power and honor, because they dread the dishonor or disgrace of evil deeds."

"The tendency has always been strong to believe that whatever received a name must be an entity or thing, having an independent existence of its own; and if no real entity answering to the name could be found, men did not for that reason suppose that none existed, but imagined that it was something peculiarly abstruse and mysterious, too high to be an object of sense. The meaning of all general, and especially of all abstract terms, became in this way enveloped in a mystical base..."

— John Stuart Mill

"There is nothing in any object, consider'd in itself, which can afford us a reason for drawing a conclusion beyond it; even after the observation of the frequent or constant conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience."

"Philosophical knowledge is the knowledge gained by reason from concepts; mathematical knowledge is the knowledge gained by reason from the construction of concepts."

— Immanuel Kant

"Nothing is more usual and more natural for those, who pretend to discover anything new to the world in philosophy and the sciences, than to insinuate the praises of their own systems, by decrying all those, which have been advanced before them. And indeed were they content with lamenting that ignorance, which we still lie under in the most important questions, that can come before the tribunal of human reason, there are few, who have an acquaintance with the sciences, that would not readily agree with them. 'Tis easy for one of judgment and learning, to perceive the weak foundation even of those systems, which have obtained the greatest credit, and have carried their pretensions highest to accurate and profound reasoning. Principles taken upon trust, consequences lamely deduced from them, want of coherence in the parts, and of evidence in the whole, these are every where to be met with in the systems of the most eminent philosophers, and seem to have drawn disgrace upon philosophy itself."

"New opinions are always suspected, and usually opposed, without any other reason but because they are not already common."

"In a Society in which there is no law, and in theory no compulsion, the only arbiter of behaviour is public opinion. But public opinion, because of the tremendous urge to conformity in gregarious animals, is less tolerant than any system of law. When human beings are governed by "thou shalt not", the individual can practise a certain amount of eccentricity: when they are supposedly governed by "love" or "reason", he is under continuous pressure to make him behave and think in exactly the same way as everyone else."

— George Orwell

"It is not without good reason said, that he who has not a good memory should never take upon him the trade of lying."

— Michel de Montaigne

"The idea that as I walk in this direction my watch goes slightly slower and I am contracted in the direction of motion and my mass has increased slightly does not correspond to everyday experience. ...the reason that it does not correspond to common sense is that we are not in the habit of traveling close to the speed of light. We may one day be in that habit, and then the Lorentz transformations will be natural, intuitive."

"My father was as well aware as anyone that Christians do not, in general, undergo the demoralizing consequences which seem inherent in such a creed, in the manner or to the extent which might have been expected from it. The same slovenliness of thought, and subjection of the reason to fears, wishes, and affections, which enable them to accept a theory involving a contradiction in terms, prevents them from perceiving the logical consequences of the theory. Such is the facility with which mankind believe at one and the same time things inconsistent with one another, and so few are those who draw from what they receive as truths, any consequences but those recommended to them by their feelings, that multitudes have held the undoubting belief in an Omnipotent Author of Hell, and have nevertheless identified that being with the best conception they were able to form of perfect goodness."

— John Stuart Mill

"men are not astonish'd at the operations of their own reason, at the same time, that they admire the instinct of animals, and find a difficulty in explaining it, merely because it cannot be reduc'd to the very same principles. reason is nothing but a wonderful and unintelligible instinct in our souls"

"The only reason why God created man is because he was disappointed with the monkey."

"The greatest and noblest conceptions have no image wrought plainly for human vision, which he who wishes to satisfy the mind of the inquirer can apply to some one of his senses and by mere exhibition satisfy the mind. We must therefore endeavor by practice to acquire the power of giving and understanding a rational definition of each one of them; for immaterial things, which are the noblest and greatest, can be exhibited by reason only, and it is for their sake that all we are saying is said. But it is always easier to practice in small matters than in greater ones."

"There is no greater evil one can suffer than to hate reasonable discourse."

"I prefer the company of peasants because they have not been educated sufficiently to reason incorrectly."

— Michel de Montaigne

"...What did I, a philosopher and Spinoza scholar, recommend? I confess that after much deliberation, I concluded that there were no good historical or legal reasons for lifting the ban, and rather good reasons against lifting it. Some may find this disappointing. But rather than see my recommendation as a betrayal of Spinoza or a capitulation to religion, I think of it as a reminder of what philosophy and religion, at their best, should both stand for: the quest for understanding and truth. The ban against Spinoza was the harshest ever issued by the Amsterdam Portuguese-Jewish community. Though the writ speaks only of his “abominable heresies and monstrous deeds,” without telling us exactly what they were, for anyone who has read Spinoza's philosophical treatises, there really is no mystery as to why he was expelled. In those works, Spinoza rejects the providential God of Abraham, Isaac and Jacob; insists that the Bible is not literally of divine origin but just a haphazard compilation of human writings handed down through the centuries; denies that Jewish law and ceremonial observance are of any validity or relevance for latter-day Jews; maintains that there is no theological, moral or metaphysical sense in which Jews are different from any other people; and rejects the idea of an immortal soul. Scholars have offered a number of alternative hypotheses to explain Spinoza's excommunication, but if he was saying any of these things around the time of his ban — and there are good reasons for thinking that he was — it is no wonder that he was punished by his community. These were heresies."

— Baruch Spinoza

"Opinions differ as to the reasons why he became the futile laborer of the underworld. To begin with, he is accused of a certain levity in regard to the gods. He stole their secrets."

— Albert Camus

"But yet they that have no Science, are in better, and nobler condition with their naturall Prudence; than men, that by their mis-reasoning, or by trusting them that reason wrong, fall upon false and absurd generall rules."

— Thomas Hobbes

"We must not confuse the present with the past. With regard to the past, no further action is possible. There have been war, plague, scandal, and treason, and there is no way of our preventing their having taken place; the executioner became an executioner and the victim underwent his fate as a victim without us; all that we can do is to reveal it, to integrate it into the human heritage, to raise it to the dignity of the aesthetic existence which bears within itself its finality; but first this history had to occur: it occurred as scandal, revolt, crime, or sacrifice, and we were able to try to save it only because it first offered us a form. Today must also exist before being confirmed in its existence: its destination in such a way that everything about it already seemed justified and that there was no more of it to reject, then there would also be nothing to say about it, for no form would take shape in it; it is revealed only through rejection, desire, hate and love. In order for the artist to have a world to express he must first be situated in this world, oppressed or oppressing, resigned or rebellious, a man among men. But at the heart of his existence he finds the exigency which is common to all men; he must first will freedom within himself and universally; he must try to conquer it: in the light of this project situations are graded and reasons for acting are made manifest."

— Simone de Beauvoir

"To scorn the dictate of reason is to scorn the commandment of God."

— Thomas Aquinas

"[Why is suicide held not to be right?] There is a doctrine uttered in secret that a man is a prisoner who has no right to open the door to his prison and run away; this is a great mystery which I do not understand. Yet I too, believe that the gods are our guardians, and that we are a possession of theirs. ...And if one of your possessions, an ox or an ass, for example took the liberty of putting himself out of the way when you had given no intimation of your wish that he should die, would you not be angry with him, and would you not punish him if you could? ...Then there may be reason in saying that a man should wait, and not take his own life until God summons him, as he is now summoning me."

"By a clock we understand anything characterized by a phenomenon passing periodically through identical phases so that we must assume, by the principle of sufficient reason, that all that happens in a given period is identical with all that happens in an arbitrary period."

— Albert Einstein
