You must acquire the best knowledge first, and without delay; it is the height of madness to learn what you will later have to unlearn.

Not to be a proud and haughty person, you have to follow the old proverb and "know thyself." That is to say, you must regard your special talents, whatever beauty or fame you have, as gifts from God, and not as things you earned for yourself. Whatever is low and mean is not God's doing, however. Here you can only blame yourself. Remember the squalor of your birth and how naked and poor you were when you crawled into the light of day like a little animal.

Most Christians are superstitious rather than pious, and except for the name of Christ differ hardly at all from superstitious pagans.

Once we have tasted the sweetness of what is spiritual, the pleasures of the world will have no attraction for us. If we disregard the shadows of things, then we will penetrate their inner substance.

I am a lover of liberty. I will not and I cannot serve a party.

But plants, though they have not powers of perception, yet, as they have life, certainly approach very nearly to those things which are endowed with sentient faculties. What then is so completely insensible as stony substance? yet even in this, there appears to be a desire of union. Thus the loadstone attracts iron to it, and holds it fast in its embrace, when so attracted. Indeed, the attraction of cohesion, as a law of love, takes place throughout all inanimate nature.

Of how much more passion than reason has Jupiter composed us? putting in, as one would say, "scarce half an ounce to a pound."

Do not be guilty of possessing a library of learned books while lacking learning yourself.

Though I certainly deserve no ill treatment from mortals, yet if the insults and repulses I receive were attended with any advantage to them, I would content myself with lamenting in silence my own unmerited indignities and man's injustice.

Morality is the beauty of Philosophy.

Behold a God more powerful than I who comes to rule over me.

In his arms, my lady lay asleep, wrapped in a veil. He woke her then and trembling and obedient. She ate that burning heart out of his hand; Weeping I saw him then depart from me.

She is the sum of nature's universe.To her perfection all of beauty tends.

Love and the gracious heart are a single thing...one can no more be without the otherthan the reasoning mind without its reason.

Love hath so long possessed me for his ownAnd made his lordship so familiar.

Love with delight discourses in my mind Upon my lady's admirable gifts...Beyond the range of human intellect.

I make no doubt... that these rules are simple, artless, and natural.

The mind must not be forced; artificial and constrained manners fill it with foolish presumption, through unnatural elevation and vain and ridiculous inflation, instead of solid and vigorous nutriment.

One of the principal reasons that diverts those who are entering upon this knowledge so much from the true path which they should follow, is the fancy that they take at the outset that good things are inaccessible, giving them the name great, lofty, elevated, sublime. This destroys everything. I would call them low, common, familiar: these names suit it better; I hate such inflated expressions.

It is not among extraordinary and fantastic things that excellence is to be found, of whatever kind it may be. We rise to attain it and become removed from it: it is oftenest necessary to stoop for it.

The best books are those, which those who read them believe they themselves could have written.

Nature, which alone is good, is wholly familiar and common.

Nothing is more common than good things: the point in question is only to discriminate them; and it is certain that they are all natural and within our reach and even known to all mankind.

Logic has borrowed, perhaps, the rules of geometry, without comprehending their force... it does not thence follow that they have entered into the spirit of geometry, and I should be greatly averse... to placing them on a level with that science that teaches the true method of directing reason.

The method of not erring is sought by all the world. The logicians profess to guide it, the geometricians alone attain it, and apart from science, and the imitations of it, there are no true demonstrations.

As to the objection that these rules are common in the world, that it is necessary to define every thing and to prove every thing, and that logicians themselves have placed them among their art, I would that the thing were true and that it were so well known... But so little is this the case, that, geometricians alone excepted, who are so few in number that they are a single in a whole nation and long periods of time, we see no others that know it.

If they have entered into the spirit if these rules, and if the rules have made sufficient impression on them to become rooted and established in their minds, they will feel how much difference there is between what is said here and what a few logicians may perhaps have written by chance approximating to it in a few passages of their works.

All who say the same things do not possess them in the same manner; and hence the incomparable author of the Art of Conversation pauses with so much care to make it understood that we must not judge of the capacity of a man by the excellence of a happy remark that we heard him make. ...let us penetrate, says he, the mind from which it proceeds... it will oftenest be seen that he will be made to disavow it on the spot, and will be drawn very far from this better thought in which he does not believe, to plunge himself into another, quite base and ridiculous.

One man will say a thing of himself without comprehending its excellence, in which another will discern a marvelous series of conclusions, which makes us affirm that it is no longer the same expression, and that he is no more indebted for it to the one from whom he has learned it, than a beautiful tree belongs to the one who cast the seed, without thinking of it, or knowing it, into the fruitful soil which caused its growth by its own fertility.

Rules necessary for definitions. Not to leave any terms at all obscure or ambiguous without definition; Not to employ in definitions any but terms perfectly known or already explained.

Rules necessary for axioms. Not to demand in axioms any but things perfectly evident.

Rules necessary for demonstrations. To prove all propositions, and to employ nothing for their proof but axioms fully evident of themselves, or propositions already demonstrated or admitted; Never to take advantage of the ambiguity of terms by failing mentally to substitute definitions that restrict or explain them.

These five rules [above] form all that is necessary to render proofs convincing, immutable, and to say all, geometrical; and the eight rules together render them even more perfect.

It is necessary to show that there is nothing so little known [as the above rules], nothing more difficult to practice, or nothing more useful and universal.

There are hardly any truths upon which we always remain agreed, and still fewer objects of pleasure which we do not change every hour, I do not know whether there is a means of giving fixed rules for adapting discourse to the inconstancy of our caprices.

Five [of the above] rules are of absolute necessity, and cannot be dispensed with without essential defect and often without error.

This art, which I call the art of persuading, and which, properly speaking, is simply the process of perfect methodical proofs, consists of three essential parts: of defining the terms of which we should avail ourselves by clear definitions, of proposing principles of evident axioms to prove the thing in question; and of always mentally substituting in the demonstrations the definition in the place of the thing defined.

If we do not secure the foundation, we cannot secure the edifice.

A few rules include all that is necessary for the perfection of the definitions, the axioms, and the demonstrations, and consequently of the entire method of the geometrical proofs of the art of persuading.

Rules for Definitions. I. Not to undertake to define any of the things so well known of themselves that the clearer terms cannot be had to explain them. II. Not to leave any terms that are at all obscure or ambiguous without definition. III. Not to employ in the definition of terms any words but such as are perfectly known or already explained.

Rules for Axioms. I. Not to omit any necessary principle without asking whether it is admittied, however clear and evident it may be. II. Not to demand, in axioms, any but things that are perfectly evident in themselves.

The principles of pleasure are not firm and stable. They are different in all mankind, and variable in every particular with such a diversity that there is no man more different from another than from himself at different times.

Rules for Demonstrations. I. Not to undertake to demonstrate any thing that is so evident of itself that nothing can be given that is clearer to prove it. II. To prove all propositions at all obscure, and to employ in their proof only very evident maxims or propositions already admitted or demonstrated. III. To always mentally substitute definitions in the place of things defined, in order not to be misled by the ambiguity of terms which have been restricted by definitions.

No one is ignorant that there are two avenues by which opinions are received into the soul, which are its two principal powers: the understanding and the will.

The whole title by which you possess your property, is not a title of nature but of a human institution.

In reading this author Montaigne and comparing him with Epictetus, I have found that they are assuredly the two greatest defenders of the two most celebrated sects of the world, and the only ones conformable to reason, since we can only follow one of these two roads, namely: either that there is a God, and then we place in him the sovereign good; or that he is uncertain, and that then the true good is also uncertain, since he is incapable of it.

Several particular maxims... are as powerful, although false, in carrying away belief, as those the most true.

If, being duke and peer, you would not be contented with my standing uncovered before you, but should also wish that I should esteem you, I should ask you to show me the qualities that merit my esteem. If you did this, you would gain it, and I could not refuse it to you with justice; but if you did not do it, you would be unjust to demand it of me; and assuredly you would not succeed, were you the greatest prince in the world.

All men are almost led to believe not of proof, but by attraction. This way is base, ignoble, and irrelevant; every one therefore disavows it. Each one professes to believe and even to love nothing but what he knows to be worthy of belief and love.

This right which you have, is not founded any more than his upon any quality or any merit in yourself which renders you worthy of it. Your soul and your body are, of themselves, indifferent to the state of boatman or that of duke; and there is no natural bond that attaches them to one condition rather than to another.
