Philosophical Works

"I show that the Word of God has not been revealed as a certain number of books, but was displayed to the prophets as a simple idea of the Divine mind, namely, obedience to God in singleness of heart, and in the practice of justice and charity; and... that this doctrine is set forth in Scripture... to the end that men might receive it willingly and with their whole heart."

"Revelation has obedience for its sole object, and therefore, in purpose no less than in foundation and method, stands entirely aloof from ordinary knowledge; each has its separate province, neither can be called the handmaid of the other."

"I do not believe anyone has reached such perfection, surpassing all others, except Christ, to whom God immediately revealed — without words or visions — the conditions which lead to salvation. So God revealed himself to the Apostles through Christ's mind, as formerly he had revealed himself to Moses by means of a heavenly voice. And therefore Christ's voice, like the one Moses heard, can be called the voice of God. And in this sense we can also say that God's wisdom, that is, a wisdom, surpassing human wisdom, assumed a human nature in Christ, and that Christ was the way to salvation."

"As men's habits of mind differ, so that some more readily embrace one form of faith, some another, for what moves one to pray may move another to scoff, I conclude … that everyone should be free to choose for himself the foundations of his creed, and that faith should be judged only by its fruits; each would then obey God freely with his whole heart, while nothing would be publicly honoured save justice and charity."

"Wholly repugnant to the general freedom are such devices as enthralling men's minds with prejudices, forcing their judgment, or employing any of the weapons of quasi-religious sedition; indeed, such seditions only spring up, when law enters the domain of speculative thought, and opinions are put on trial and condemned on the same footing as crimes, while those who defend and follow them are sacrificed, not to public safety, but to their opponents' hatred and cruelty. If deeds only could be made the grounds of criminal charges, and words were always allowed to pass free, such seditions would be divested of every semblance of justification, and would be separated from mere controversies by a hard and fast line."

"Seeing that we have the rare happiness of living in a republic, where everyone's judgment is free and unshackled, where each may worship God as his conscience dictates, and where freedom is esteemed before all things dear and precious, I have believed that I should be undertaking no ungrateful or unprofitable task, in demonstrating that not only can such freedom be granted without prejudice to the public peace, but also that without such freedom, piety cannot flourish nor the public peace be secure. Such is the chief conclusion I seek to establish in this treatise..."

"If, in despotic statecraft, the supreme and essential mystery be to hoodwink the subjects, and to mask the fear, which keeps them down, with the specious garb of religion, so that men may fight as bravely for slavery as for safety, and count it not shame but highest honour to risk their blood and their lives for the vainglory of a tyrant; yet in a free state no more mischievous expedient could be planned or attempted."

"Faith has become a mere compound of credulity and prejudices—aye, prejudices too, which degrade man from rational being to beast, which completely stifle the power of judgment between true and false, which seem, in fact, carefully fostered for the purpose of extinguishing the last spark of reason! Piety, great God! and religion are become a tissue of ridiculous mysteries; men, who flatly despise reason, who reject and turn away from understanding as naturally corrupt, these, I say, these of all men, are thought, O lie most horrible! to possess light from on High. Verily, if they had but one spark of light from on High, they would not insolently rave, but would learn to worship God more wisely, and would be as marked among their fellows for mercy as they now are for malice; if they were concerned for their opponents' souls, instead of for their own reputations, they would no longer fiercely persecute, but rather be filled with pity and compassion. ...never even in sleep have they caught a glimpse of Scripture's Divine nature."

"From ignorance of this truth, or... from neglect of it, the majority of those who... aspired to be philosophers, blindly followed Aristotle, so... frequently corrupted... his writings, and attributed... opinions... he would not recognise... and those who did not follow him, among whom are... many of the greatest minds, did yet not escape... his opinions in their youth... the staple... in the schools; and thus... they could not rise to the knowledge of true principles."

"The authority of the prophets has weight only in matters of morality, and... their speculative doctrines affect us little."

"When the prophets, in speaking of this election which regards only true virtue, mixed up much concerning sacrifices and ceremonies, and the rebuilding of the temple and city, they wished by such figurative expressions, after the manner and nature of prophecy, to expound matters spiritual, so as at the same time to show to the Jews, whose prophets they were, the true restoration of the state and of the temple to be expected about the time of Cyrus. At the present time, therefore, there is absolutely nothing which the Jews can arrogate to themselves beyond other people. As to their continuance so long after dispersion and the loss of empire, there is nothing marvellous in it, for they so separated themselves from every other nation as to draw down upon themselves universal hate, not only by their outward rites, rites conflicting with those of other nations, but also by the sign of circumcision which they most scrupulously observe. That they have been preserved in great measure by Gentile hatred, experience demonstrates."

"The ultimate aim of government is not to rule, or restrain, by fear, nor to exact obedience, but, contrariwise, to free every man from fear, that he may live in all possible security ; in other words, to strengthen his natural right to exist and work without injury to himself or others. No, the object of government is not to change men from rational beings into beasts or puppets, but to enable them to develop their minds and bodies in security, and to employ their reason unshackled; neither showing hatred, anger, or deceit, nor watched with the eyes of jealousy and injustice. In fact, the true aim of government is liberty."

"Si homines res omnes suas certo consilio regere possent, vel si fortuna ipsis prospera semper foret, nulla superstitione tenerentur. Sed quoniam eo saepe angustiarum rediguntur, ut consilium nullum adferre queant, et plerumque ob incerta fortunae bona, quae sine modo cupiunt, inter spem metumque misere fluctuant, ideo animum ut plurimum ad quidvis credendum pronissimum habent ; qui dum in dubio facili momento huc, atque illuc pellitur, et multo facilius, dum spe, et metu agitatus haeret, praesidens alias, jactabundus, ac tumidus. Atque haec neminem ignorare existimo, quamvis plerosque se ipsos ignorare credam ; nemo enim inter homines ita vixit, qui non viderit, plerosque in rebus prosperis, etsi imperitissimi sint, sapientiâ ita abundare, ut sibi injuriam fieri credant, si quis iis consilium dare velit ; in adversis autem, quo se vertant, nescire, et consilium ab unoquoque supplices petere, nec ullum tam ineptum tamque ad absurdum, aut vanum audire, quod non sequantur : Deinde levissimis etiam de causis jam meliora sperare, rursus deteriora timere ; si quid enim, dum in metu versantur, contingere vident, quod eos praeteriti alicujus boni, vel mali memores reddit, id exitum aut faelicem, aut infaelicem obnunciare putant, quod propterea, quamvis centies fallat, faustum vel infaustum omen vocant. Si quid porro insolitum magna cum admiratione vident, id prodigium esse credunt, quod Deorum aut summi Numinis iram indicat, quodque adeo hostiis, et votis non piare, nefas habent homines superstitioni obnoxii, et religioni adversi ; eumque ad modum infinita fingunt, et quasi tota natura cum ipsis insaniret, eandem miris modis interpretantur.Cum igitur haec ita sese habeant, tum praecipue vidimus, eos omni superstitionis generi addictissimos esse, qui incerta sine modo cupiunt, omnesque tum maxime, cum scilicet in periculis versantur, et sibi auxilio esse nequeunt, votis, et lachrimis muliebribus divina auxilia implorare, et rationem (quia ad vana, quae cupiunt, certam viam ostendere nequit) caecam appellare, humanamque sapientiam vanam ; et contrà imaginationis deliria, somnia, et pueriles ineptias divina responsa credere, imo Deum sapientes aversari, et sua decreta non menti, sed pecudum fibris inscripsisse, vel eadem stultos, vesanos, et aves divino afflatu, et instinctus praedicere. Tantum timor homines insanire facit. Causa itaque, a quâ superstitio oritur, et fovetur, metus est."

"[T]he philosophers... all laid down as a principle what they did not perfectly know. ...I know none of them who did not suppose that there was gravity in terrestrial bodies; but although experience shows us... [heavy] bodies... descend towards the centre of the earth, we do not... know the nature of gravity... [i.e.,] the cause or principle in virtue of which bodies descend, and we must derive our knowledge of it from some other source."

"XXV. What motion is properly so called... is THE TRANSPORING OF ONE PART OF MATTER OR OF ONE BODY FROM THE VICINITY OF THOSE BODIES THAT ARE IN IMMEDIATE CONTACT WITH IT, OR WHICH WE REGARD AT REST, TO THE VICINITY OF OTHER BODIES."

"As the mass of mankind remains always at about the same pitch of misery, it never assents long to any one remedy, but is always best pleased by a novelty which has not yet proved illusive."

"One would be inclined to think, from the precautions everywhere taken, that we are overstocked with husbandmen, and are afraid of a shortage of philosophers. I will not venture here to enter into a comparison between agriculture and philosophy, as they would not bear it. I shall only ask What is philosophy? What is contained in the writings of the most celebrated philosophers? What are the lessons of these friends of wisdom. To hear them, should we not take them for so many mountebanks, exhibiting themselves in public, and crying out, Here, Here, come to me, I am the only true doctor? One of them teaches that there is no such thing as matter, but that everything exists only in representation. Another declares that there is no other substance than matter, and no other God than the world itself. A third tells you that there are no such things as virtue and vice, and that moral good and evilare chimeras; while a fourth informs you that men are only beasts of prey, and may conscientiously devour one another."

"What are we to think of those compilers who have indiscreetly broken open the door of the sciences, and introduced into their sanctuary a populace unworthy to approach it, when it was greatly to be wished that all who should be found incapable of making a considerable progress in the career of learning should have been repulsed at the entrance, and thereby cast upon those arts which are useful to society. A man who will be all his life a bad versifier, or a third-rate geometrician, might have made nevertheless an excellent clothier. Those whom nature intended for her disciples have not needed masters. Bacon, Descartes and Newton, those teachers of mankind, had themselves no teachers. What guide indeed could have taken them so far as their sublime genius directed them? Ordinary masters would only have cramped their intelligence, by confining it within the narrow limits of their own capacity. It was from the obstacles they met with at first, that they learned to exert themselves, and bestirred themselves to traverse the vast field which they covered. If it be proper to allow some men to apply themselves to the study of the arts and sciences, it is only those who feel themselves able to walk alone in their footsteps and to outstrip them. It belongs only to these few to raise monuments to the glory of the human understanding. But if we are desirous that nothing should be above their genius, nothing should be beyond their hopes. This is the only encouragement they require."

"We have physicists, geometricians, chemists, astronomers, poets, musicians, and painters in plenty; but we have no longer a citizen among us; or if there be found a few scattered over our abandoned countryside, they are left to perish there unnoticed and neglected. Such is the condition to which we are reduced, and such are our feelings towards those who give us our daily bread, and our children milk."

"Let not princes disdain to admit into their councils those who are most capable of giving them good advice. Let them renounce the old prejudice, which was invented by the pride of the great, that the art of governing mankind is more difficult than that of instructing them; as if it was easier to induce men to do good voluntarily, than to compel them to it by force. Let the learned of the first rank find an honourable refuge in their courts; let them there enjoy the only recompense worthy of them, that of promoting by their influence the happiness of the peoples they have enlightened by their wisdom. It is by this means only that we are likely to see what virtue, science and authority can do, when animated by the noblest emulation, and working unanimously for the happiness of mankind."

"The ancient republics of Greece, with that wisdom which was so conspicuous in most of their institutions, forbade their citizens to pursue all those inactive and sedentary occupations, which by enervating and corrupting the body diminish also the vigour of the mind. With what courage, in fact, can it be thought that hunger and thirst, fatigues, dangers and death, can be faced by men whom the smallest want overwhelms and the slightest difficulty repels?"

"We see, on every side, huge institutions, where our youth are educated at great expense, and instructed in everything but their duty. Your children will be ignorant of their own language, when they can talk others which are not spoken anywhere. They will be able to compose verses which they can hardly understand; and, without being capable of distinguishing truth from error, they will possess the art of making them unrecognisable by specious arguments. But magnanimity, equity, temperance, humanity and courage will be words of which they know not the meaning. The dear name of country will never strike on their ears; and if they ever hear speak of God, it will be less to fear, than to be frightened of, Him. I would as soon, said a wise man, that my pupil had spent his time in the tennis court as in this manner; for there his body at least would have got exercise."

"As for us, ordinary men, on whom Heaven has not been pleased to bestow such great talents; as we are not destined to reap such glory, let us remain in our obscurity. Let us not covet a reputation we should never attain, and which, in the present state of things, would never make up to us for the trouble it would have cost us, even if we were fully qualified to obtain it. Why should we build our happiness on the opinions of others, when we can find it in our own hearts? Let us leave to others the task of instructing mankind in their duty, and confine ourselves to the discharge of our own."

"The question is no longer whether a man is honest, but whether he is clever. We do not ask whether a book is useful, but whether it is well-written."

"Useless, do I say? Would God they were! Society would be more peaceful, and morals less corrupt. But these vain and futile declaimers go forth on all sides, armed with their fatal paradoxes, to sap the foundations of our faith, and nullify virtue. They smile contemptuously at such old names as patriotism and religion, and consecrate their talents and philosophy to the destruction and defamation of all that men hold sacred."

"A taste for ostentation never prevails in the same minds as a taste for honesty. No, it is impossible that understandings, degraded by a multitude of futile cares, should ever rise to what is truly great and noble; even if they had the strength, they would want the courage."

"To live without doing some good is a great evil as well in the political as in the moral world; and hence every useless citizen should be regarded as a pernicious person. Tell me then, illustrious philosophers, of whom we learn theratios in which attraction acts in vacuo; and in the revolution of the planets, the relations of spaces traversed in equal times; by whom we are taught what curves have conjugate points, points of inflexion, and cusps; how the soul and body correspond, like two clocks, without actual communication; what planets may be inhabited; and what insects reproduce in an extraordinary manner. Answer me, I say, you from whom we receive all this sublime information, whether we should have been less numerous, worse governed, less formidable, less flourishing, or more perverse, supposing you had taught us none of all these fine things."

"We cannot reflect on the morality of mankind without contemplating with pleasure the picture of the simplicity which prevailed in the earliest times. This image may be justly compared to a beautiful coast, adorned only by the hands of nature; towards which our eyes are constantly turned, and which we see receding with regret. While men were innocent and virtuous and loved to have the gods for witnesses of their actions, they dwelt together in the same huts; but when they became vicious, they grew tired of such inconvenient onlookers, and banished them to magnificent temples. Finally, they expelled their deities even from these, in order to dwell there themselves."

"Astronomy was born of superstition, eloquence of ambition, hatred, falsehood and flattery; geometry of avarice; physics of an idle curiosity; and even moral philosophy of human pride. Thus the arts and sciences owe their birth to our vices; we should be less doubtful of their advantages, if they had sprung from our virtues."

"When the Goths ravaged Greece, the libraries only escaped the flames owing to an opinion that was set on foot among them, that it was best to leave the enemy with a possession so calculated to divert their attention from military exercises,and keep them engaged in indolent and sedentary occupations."

"And life is like a bird that only rests when they can find time. Life is another lie given to humans for satisfaction."

"What a variety of dangers surrounds us! What a number of wrong paths present themselves in the investigation of the sciences! Through how many errors, more perilous than truth itself is useful, must we not pass to arrive at it? The disadvantages we lie under are evident; for falsehood is capable of an infinite variety of combinations; but the truth has only one manner of being. Besides, where is the man who sincerely desires to find it? Or even admitting his good will, by what characteristic marks is he sure of knowing it? Amid the infinite diversity of opinions where is the criterion 1 by which we may certainly judge of it? Again, what is still more difficult, should we even be fortunate enough to discover it, who among us will know how to make right use of it? If our sciences are futile in the objects they propose, they are no less dangerous in the effects they produce. Being the effect of idleness, they generate idleness in their turn; and an irreparable loss of time is the first prejudice which they must necessarily cause to society."

"Before that time the Romans were satisfied with the practice of virtue; they were undone when they began to study it."

"What would the great soul of Fabricius have felt, if it had been his misfortune to be called back to life, when he saw the pomp and magnificence of that Rome, which his arm had saved from ruin, and his honourable name made more illustrious than all its conquests. “Ye gods!” he would have said, “what has become of those thatched roofs and rustic hearths, which were formerly the habitations of temperance and virtue? What fatal splendour has succeeded the ancient Roman simplicity? What is this foreign language, this effeminacy of manners? What is the meaning of these statues, paintings and buildings? Fools, what have you done? You, the lords of the earth, have made yourselves the slaves of the frivolous nations you have subdued. You are governed by rhetoricians, and it has been only to enrich architects, painters, sculptors and stage-players that you have watered Greece and Asia with your blood. Even the spoils of Carthage are the prize of a flute-player. Romans! Romans! make haste to demolish those amphitheatres, break to pieces thosestatues, burn those paintings; drive from among you those slaves who keep you in subjection, and whose fatal arts are corrupting your morals. Let other hands make themselves illustrious by such vain talents; the only talent worthy of Rome is that of conquering the world and making virtue its ruler."

"But hear the judgment which the principal, and most unhappy of them, passed on the artists and learned men of his day. “I have considered the poets,” says he, “and I look upon them as people whose talents impose both on themselves and on others; they give themselves out for wise men, and are taken for such; but in reality they are anything sooner than that.” “From the poets,” continues Socrates, “I turned to the artists. Nobody was more ignorant of the arts than myself; nobody was more fully persuaded that the artists were possessed of amazing knowledge. I soon discovered, however, that they were in as bad a way as the poets, and that both had fallen into the same misconception. Because the most skilful of them excel others in their particular jobs, they think themselves wiser than all the rest of mankind. This arrogance spoilt all their skill in my eyes, so that, putting myself in the place of the oracle, and asking myself whether I would rather be what I am or what they are, know what they know, or know that I know nothing, I very readily answered, for myself and the god, that I had rather remain as I am."

"When Cyneas took the Roman senate for an assembly of kings, he was not struck by either useless pomp or studied elegance. He heard there none of that futile eloquence, which is now the study and the charm of frivolous orators. What then was the majesty that Cyneas beheld? Fellow citizens, he saw the noblest sight that ever existed under heaven, a sight which not all your riches or your arts can show; an assembly of two hundred virtuous men, worthy to command in Rome, and to govern the world.”"

"Not all the eloquence of Demosthenes could breathe life into a body which luxury and the arts had once enervated."

"Rome, once the shrine of virtue, became the theatre of vice, a scorn among the nations, and an object of derision even to barbarians. Thus the capital of the world at length submitted to the yoke of slavery it had imposed on others, and the very day of its fall was the eve of that on which it conferred on one of its citizens the title of Arbiter of Good Taste."

"It is true that in France Socrates would not have drunk the hemlock, but he would have drunk of a potion infinitely more bitter, of insult, mockery and contempt a hundred times worse than death."

"What advantage has that country reaped from the honours bestowed on its learned men? Can it be that of being peopled by a race of scoundrels and slaves?"

"Necessity raised up thrones; the arts and sciences have made them strong. Powers of the earth, cherish all talents and protect those who cultivate them. To them, happy slaves, you owe that delicacy and exquisiteness of taste, which is so much your boast, that sweetness of disposition and urbanity of manners which make intercourse so easy and agreeable among you—in a word, the appearance of all the virtues, without being in possession of one of them."

"Richness of apparel may proclaim the man of fortune,and elegance the man of taste; but true health and manliness are known by different signs. It is under the homespun of the labourer, and not beneath the gilt and tinsel of the courtier, that we should look for strength and vigour of body."

"So long as government and law provide for the security and well-being of men in their common life, the arts, literature and the sciences, less despotic though perhaps more powerful, fling garlands of flowers over the chains which weigh them down. They stifle in men’s breasts that sense of original liberty, for which they seem to have been born; cause them to love their own slavery, and so make of them what is called a civilised people."

"Before art had moulded our behaviour, and taught our passions to speak an artificial language, our morals were rude but natural; and the different ways in which we behaved proclaimed at the first glance the difference of our dispositions. Human nature was not at bottom better then than now; but men found their security in the ease with which they could see through one another, and this advantage, of which we no longer feel the value, prevented their having many vices."

"In our day, now that more subtle study and a more refined taste have reduced the art of pleasing to a system, there prevails in modern manners a servile and deceptive conformity; so that one would think every mind had been cast in the same mould. Politeness requires this thing; decorum that; ceremony has its forms, and fashion its laws, and these we must always follow, never the promptings of our own nature"

"Thus it is that luxury, profligacy and slavery, have been, in all ages, the scourge of the efforts of our pride to emerge from that happy state of ignorance, in which the wisdom of providence had placed us. That thick veil with which it has covered all its operations seems to be a sufficient proof that it never designed us for such fruitless researches. But is there, indeed, one lesson it has taught us, by which we have rightly profited, or which we have neglected with impunity? Let men learn for once that nature would have preserved them from science, as a mother snatches a dangerous weapon from the hands of her child. Let them know that all the secrets she hides are so many evils from which she protects them, and that the very difficulty they find in acquiring knowledge is not the least of her bounty towards them. Men are perverse; but they would have been far worse, if they had had the misfortune to be born learned."

"It is a noble and beautiful spectacle to see man raising himself, so to speak, from nothing by his own exertions; dissipating, by the light of reason, all the thick clouds in which he was by nature enveloped; mounting above himself; soaring in thought even to the celestial regions; like the sun, encompassing with giant strides the vast extent of the universe; and, what is still grander and more wonderful, going back into himself, there to study man and get to know his own nature, his duties and his end. All these miracles we have seen renewed within the last few generations."

"The following pages contain a discussion of one of the most sublime and interesting of all moral questions. It is not concerned, however, with those metaphysical subtleties, which of late have found their way into every department of literature, and from which even our academic curricula are not always free. We have now to do with one of those truths on which the happiness of mankind depends."

"I foresee that I shall not readily be forgiven for having taken up the position I have adopted. Setting myself up against all that is nowadays most admired, I can expect no less than a universal outcry against me: nor is the approbation of a few sensible men enough to make me count on that of the public. But I have taken my stand, and I shall be at no pains to please either intellectuals or men of the world"

"The problem of education in a democratic society is to do away with ... dualism and to construct a course of studies which makes thought a guide of free practice for all and which makes leisure a reward of accepting responsibility for service, rather than a state of exemption from it."
