…what is man in the midst of nature? A nothing in comparison with the infinite, an all in comparison with nothingness: a mean between nothing and all. Infinitely far from comprehending the extremes, the end of things and their principle are for him inevitably concealed in an impenetrable secret; equally incapable of seeing the nothingness whence he is derived, and the infinity in which he is swallowed up.
— Blaise Pascal
L’homme n’est qu’un roseau, le plus faible de la nature, mais c’est un roseau pensant. Il ne faut pas que l’univers entier s’arme pour l’écraser; une vapeur, une goutte d’eau suffit pour le tuer. Mais quand l’univers l’écraserait, l’homme serait encore plus noble que ce qui le tue, parce qu’il sait qu’il meurt et l’avantage que l’univers a sur lui; l’univers n'en sait rien.
Man is a reed, the feeblest thing in nature. But a reed that can think. The whole universe need not fly to arms to kill him ; for a little heat or a drop of water can slay a man. But, even then, man would be nobler than his destroyer, for he would know he died, while the whole universe would know nothing of its victory.

L’homme n’est qu’un roseau, le plus faible de la nature; mais c’est un roseau pensant.
Man is but a reed, the weakest thing in nature; but a thinking reed.

— Blaise Pascal
La puissance des mouches. Elles gagnent des batailles, empêchent notre âme d’agir, mangent notre corps.
Flies are so mighty that they win battles, paralyse our minds, eat up our bodies.
Flies are so mighty that they win battles, paralyse our minds, eat up our bodies.
— Blaise Pascal
On se persuade mieux, pour l’ordinaire, par les raisons qu’on a soi-même trouvées, que par celles qui sont venues dans l’esprit des autres.
We are generally more effectually persuaded by reasons we have ourselves discovered than by those which have occurred to others.

— Blaise Pascal
Puisqu'on ne peut être universel en sachant tout ce qui se peut sur tout, il faut savoir peu de tout. Car il est bien plus beau de savoir quelque chose de tout que de savoir rout d'une chose; cette universalité est la plus belle. Si on pouvait avoir les deux, encore mieux.
Since we cannot be universal and know all that is to be known of everything, we ought to know a little about everything, For it is far better to know something about everything than to know all about one thing.
Since we cannot be universal and know all that is to be known of everything, we ought to know a little about everything, For it is far better to know something about everything than to know all about one thing.
— Blaise Pascal
~~[Orphan ?]~~ Reason is the slow and tortuous method by which those who do not know the truth discover it.
— Blaise Pascal
A game is on, at the other end of this infinite distance, and heads or tails will turn up. What will you wager? According to reason you cannot leave either; according to reason you cannot leave either undone... Yes, but wager you must; there is no option, you have embarked on it. So which will you have. Come. Since you must choose, let us see what concerns you least. You have two things to lose: truth and good, and two things to stake: your reason and your will, your knowledge and your happiness. And your nature has two things to shun: error and misery. Your reason does not suffer by your choosing one more than the other, for you must choose. That is one point cleared. But your happiness? Let us weigh gain and loss in calling heads that God is. Reckon these two chances: if you win, you win all; if you lose, you lose naught. Then do not hesitate, wager that He is.
— Blaise Pascal
All err the more dangerously because each follows a truth. Their mistake lies not in following a falsehood but in not following another truth.
— Blaise Pascal
All the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.
— Blaise Pascal
Contradiction is not a sign of falsity, nor the lack of contradiction a sign of truth.
— Blaise Pascal
Every gambler stakes a certainty to gain an uncertainty, and yet he stakes a finite certainty against a finite uncertainty without acting unreasonably. … The uncertainty of gain is proportioned to the certainty of the stake, according to the proportion of chances of gain and loss, and if therefore there are as many chances on one side as on the other, the game is even.
— Blaise Pascal
Everything that is written merely to please the author is worthless.
— Blaise Pascal
Faith is different from proof; the latter is human, the former is a Gift from God.
— Blaise Pascal
Few men speak humbly of humility, chastely of chastity, skeptically of skepticism.
— Blaise Pascal
I cannot judge my work while I am doing it. I have to do as painters do, stand back and view it from a distance, but not too great a distance. How great? Guess.
— Blaise Pascal
I have made this one [letter] longer than usual because I did not have the leisure to make it shorter.
— Blaise Pascal
I have spent much time in the study of the abstract sciences; but the paucity of persons with whom you can communicate on such subjects disgusted me with them. When I began to study man, I saw that these abstract sciences are not suited to him, and that in diving into them, I wandered farther from my real object than those who knew them not, and I forgave them for not having attended to these things. I expected then, however, that I should find some companions in the study of man, since it was so specifically a duty. I was in error. There are fewer students of man than of geometry.
— Blaise Pascal
I will paint for [man] not only the visible universe, but all that he can conceive of nature’s immensity in the womb of an atom.
— Blaise Pascal
It is not certain that everything is uncertain.
— Blaise Pascal
It is the heart which experiences God, and not the reason.
— Blaise Pascal
Knowledge of physical science will not console me for ignorance of morality in time of affliction, but knowledge of morality will always console me for ignorance of physical science.
— Blaise Pascal
Let him look at that dazzling light hung aloft as an eternal lamp to lighten the universe; let him behold the earth, a mere dot compared with the vast circuit which that orb describes, and stand amazed to find that the vast circuit itself is but a very fine point compared with the orbit traced by the stars as they roll their course on high. But if our vision halts there, let imagination pass beyond; it will fail to form a conception long before Nature fails to supply material. The whole visible world is but an imperceptible speck in the ample bosom of Nature. No notion comes near it. Though we may extend our thought beyond imaginable space, yet compared with reality we bring to birth mere atoms. Nature is an infinite sphere whereof the centre is everywhere, the circumference nowhere. In short, imagination is brought to silence at the thought, and that is the most perceptible sign of the all-power of God.
Let man reawake and consider what he is compared with the reality of things; regard himself lost in this remote corner of Nature; and from the tiny cell where he lodges, to wit the Universe, weigh at their true worth earth, kingdoms, towns, himself. What is a man face to face with infinity?

— Blaise Pascal
Let no one say that I have said nothing new; the arrangement of the subject is new. When we play tennis, we both play with the same ball, but one of us places it better.
— Blaise Pascal
Let us weigh the gain and the loss in wagering that God is. Let us consider the two chances. If you gain, you gain all; if you lose, you lose nothing. Wager then without hesitation that He is.
— Blaise Pascal
Logic has borrowed the rules of geometry without understanding its power. … I am far from placing logicians by the side of geometers who teach the true way to guide the reason. … The method of avoiding error is sought by every one. The logicians profess to lead the way, the geometers alone reach it, and aside from their science there is no true demonstration.
— Blaise Pascal
Look somewhere else for someone who can follow you in your researches about numbers. For my part, I confess that they are far beyond me, and I am competent only to admire them.
— Blaise Pascal
Man is but a reed, the most feeble thing in nature; but he is a thinking reed.
— Blaise Pascal
Man is full of desires: he loves only those who can satisfy them all. “This man is a good mathematician,” someone will say. But I have no concern for mathematics; he would take me for a proposition. “That one is a good soldier.” He would take me for a besieged town. I need, that is to say, a decent man who can accommodate himself to all my desires in a general sort of way.
— Blaise Pascal
Mathematics contain a great number of premises, and there is perhaps a kind of intellect that can search with ease a few premises to the bottom, and cannot in the least penetrate those matters in which there are many premises.
— Blaise Pascal
Men despise religion; they hate it, and they fear it is true.
— Blaise Pascal
Nature … is an infinite sphere of which the center is everywhere and the circumference nowhere.
— Blaise Pascal
Our nature consists in motion; complete rest is death.
— Blaise Pascal
Our notion of symmetry is derived from the human face. Hence, we demand symmetry horizontally and in breadth only, not vertically nor in depth.
— Blaise Pascal
Perfect clarity would profit the intellect but damage the will.
— Blaise Pascal
Religion is so great a thing that it is right that those who will not take the trouble to seek it if it be obscure, should be deprived of it.
— Blaise Pascal
Rivers are roads which move, and which carry us whither we desire to go.
— Blaise Pascal
The chief malady of man is restless curiosity about things which he cannot understand; and it is not so bad for him to be in error as to be curious to no purpose.
— Blaise Pascal
The eternal silence of these infinite spaces fills me with dread.
— Blaise Pascal
The greater intellect one has, the more originality one finds in men. Ordinary persons find no difference between men.

— Blaise Pascal
The heart has its reasons which reason does not know.
— Blaise Pascal
The last proceeding of reason is to recognize that there an infinity of things which are beyond it.
— Blaise Pascal
The last thing one settles in writing a book is what one should put first.
— Blaise Pascal

— Blaise Pascal
The parts of the universe … all are connected with each other in such a way that I think it to be impossible to understand any one without the whole.
— Blaise Pascal
The state of man is changeableness, ennui, anxiety.
Condition de l’homme, inconstance, ennui, inquietude.
Condition de l’homme, inconstance, ennui, inquietude.
— Blaise Pascal
There are then two kinds of intellect: the one able to penetrate acutely and deeply into the conclusions of given premises, and this is the precise intellect; the other able to comprehend a great number of premises without confusing them, and this is the mathematical intellect. The one has force and exactness, the other comprehension. Now the one quality can exist without the other; the intellect can be strong and narrow, and can also be comprehensive and weak.
— Blaise Pascal
There are three leading objects in the study of truth:—one, to discover it; another, to demonstrate it when discovered; the last, to separate it from all admixture of falsehood.
— Blaise Pascal
There are two types of mind … the mathematical, and what might be called the intuitive. The former arrives at its views slowly, but they are firm and rigid; the latter is endowed with greater flexibility and applies itself simultaneously to the diverse lovable parts of that which it loves.
— Blaise Pascal
They say that habit is second nature. Who knows but nature is only first habit?
— Blaise Pascal
Those who are accustomed to judge by feeling do not understand the process of reasoning, because they want to comprehend at a glance and are not used to seeking for first principles. Those, on the other hand, who are accustomed to reason from first principles do not understand matters of feeling at all, because they look for first principles and are unable to comprehend at a glance.
— Blaise Pascal
Those who judge of a work by rule are in regard to others as those who have a watch are in regard to others. One says, “It is two hours ago”; the other says, “It is only three-quarters of an hour.” I look at my watch, and say to the one, “You are weary,” and to the other, “Time gallops with you”; for it is only an hour and a half ago, and I laugh at those who tell me that time goes slowly with me, and that I judge by imagination. They do not know that I judge by my watch.
— Blaise Pascal
Through space the universe grasps me and swallows me up like a speck. But through thought I grasp it.
— Blaise Pascal
To deny, to believe, and to doubt well are to a man what the race is to a horse.
— Blaise Pascal
Vanity is so anchored in the heart of man … and wishes to have his admirers. … Those who write against it want to have the glory of having written well, and those who read it desire the glory of having read it. I who write this have perhaps this desire, and perhaps those who will read it….
— Blaise Pascal
We are never in search of things, but always in search of the search.
— Blaise Pascal
We are so presumptuous that we would wish to be known by all the world, even by people who shall come after, when we shall be no more; and we are so vain that the esteem of five or six neighbours delights and contents us.
— Blaise Pascal
We do not worry about being respected in towns through which we pass. But if we are going to remain in one for a certain time, we do worry. How long does this time have to be?
— Blaise Pascal
We know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.
— Blaise Pascal
We know the truth not only through our reason but also through our heart. It is through the latter that we know first principles, and reason, which has nothing to do with it, tries in vain to refute them.
— Blaise Pascal
We know truth, not only by the reason, but also by the heart.
— Blaise Pascal
We may have three principal objects in the study of truth: one to discover it when it is sought; another to demonstrate it when it is possessed; and a third, to discriminate it from the false when it is examined.
— Blaise Pascal
We run carelessly to the precipice, after we have put something before us to prevent us seeing it.
— Blaise Pascal
What a chimera ... is man ! What a novelty, what a monster, what a chaos, what a subject of contradiction, what a prodigy! A judge of all things, feeble worm of the earth, depository of the truth, cloacae of uncertainty and error, the glory and the shame of the universe!
— Blaise Pascal
What is man in nature? A Nothing in comparison with the Infinite, an All in comparison with the
Nothing, a mean between nothing and everything.
— Blaise Pascal
Whatever compass of mind one may have, he is capable of only one great passion.
— Blaise Pascal
When everything moves at the same time, nothing moves in appearance.
Quand tout se remue également, rien ne se remue en apparence.
Quand tout se remue également, rien ne se remue en apparence.
— Blaise Pascal
When the passions become masters, they are vices.
— Blaise Pascal
When we see a natural style, we are astonished and delighted; for we expected to see an author, and we find a man.
— Blaise Pascal
Words differently arranged have a different meaning, and meanings differently arranged have different effects.
— Blaise Pascal
You see, if the height of the mercury [barometer] column is less on the top of a mountain than at the foot of it (as I have many reasons for believing, although everyone who has so far written about it is of the contrary opinion), it follows that the weight of the air must be the sole cause of the phenomenon, and not that abhorrence of a vacuum, since it is obvious that at the foot of the mountain there is more air to have weight than at the summit, and we cannot possibly say that the air at the foot of the mountain has a greater aversion to empty space than at the top.
— Blaise Pascal
Quotes by others about Blaise Pascal (9)
I came to biochemistry through chemistry; I came to chemistry, partly by the labyrinthine routes that I have related, and partly through the youthful romantic notion that the natural sciences had something to do with nature. What I liked about chemistry was its clarity surrounded by darkness; what attracted me, slowly and hesitatingly, to biology was its darkness surrounded by the brightness of the givenness of nature, the holiness of life. And so I have always oscillated between the brightness of reality and the darkness of the unknowable. When Pascal speaks of God in hiding, Deus absconditus, we hear not only the profound existential thinker, but also the great searcher for the reality of the world. I consider this unquenchable resonance as the greatest gift that can be bestowed on a naturalist.
In the last fifteen years we have witnessed an event that, I believe, is unique in the history of the natural sciences: their subjugation to and incorporation into the whirls and frenzies of disgusting publicity and propaganda. This is no doubt symptomatic of the precarious position assigned by present-day society to any form of intellectual activity. Such intellectual pursuits have at all times been both absurd and fragile; but they become ever more ludicrous when, as is now true of science, they become mass professions and must, as homeless pretentious parasites, justify their right to exist in a period devoted to nothing but the rapid consumption of goods and amusements. These sciences were always a divertissement in the sense in which Pascal used the word; but what is their function in a society living under the motto lunam et circenses? Are they only a band of court jesters in search of courts which, if they ever existed, have long lost their desire to be amused?
Science can tell us what exists; but to compare the worths, both of what exists and of what does not exist, we must consult not science, but what Pascal calls our heart.
Distrust even Mathematics; albeit so sublime and highly perfected, we have here a machine of such delicacy it can only work in vacuo, and one grain of sand in the wheels is enough to put everything out of gear. One shudders to think to what disaster such a grain of sand may bring a Mathematical brain. Remember Pascal.
As far as I see, such a theory [of the primeval atom] remains entirely outside any metaphysical or religious question. It leaves the materialist free to deny any transcendental Being. He may keep, for the bottom of space-time, the same attitude of mind he has been able to adopt for events occurring in non-singular places in space-time. For the believer, it removes any attempt to familiarity with God, as were Laplace’s chiquenaude or Jeans’ finger. It is consonant with the wording of Isaiah speaking of the “Hidden God” hidden even in the beginning of the universe … Science has not to surrender in face of the Universe and when Pascal tries to infer the existence of God from the supposed infinitude of Nature, we may think that he is looking in the wrong direction.
Foreshadowings of the principles and even of the language of [the infinitesimal] calculus can be found in the writings of Napier, Kepler, Cavalieri, Pascal, Fermat, Wallis, and Barrow. It was Newton's good luck to come at a time when everything was ripe for the discovery, and his ability enabled him to construct almost at once a complete calculus.
Kepler’s discovery would not have been possible without the doctrine of conics. Now contemporaries of Kepler—such penetrating minds as Descartes and Pascal—were abandoning the study of geometry ... because they said it was so UTTERLY USELESS. There was the future of the human race almost trembling in the balance; for had not the geometry of conic sections already been worked out in large measure, and had their opinion that only sciences apparently useful ought to be pursued, the nineteenth century would have had none of those characters which distinguish it from the ancien régime.
It is not surprising, in view of the polydynamic constitution of the genuinely mathematical mind, that many of the major heros of the science, men like Desargues and Pascal, Descartes and Leibnitz, Newton, Gauss and Bolzano, Helmholtz and Clifford, Riemann and Salmon and Plücker and Poincaré, have attained to high distinction in other fields not only of science but of philosophy and letters too. And when we reflect that the very greatest mathematical achievements have been due, not alone to the peering, microscopic, histologic vision of men like Weierstrass, illuminating the hidden recesses, the minute and intimate structure of logical reality, but to the larger vision also of men like Klein who survey the kingdoms of geometry and analysis for the endless variety of things that flourish there, as the eye of Darwin ranged over the flora and fauna of the world, or as a commercial monarch contemplates its industry, or as a statesman beholds an empire; when we reflect not only that the Calculus of Probability is a creation of mathematics but that the master mathematician is constantly required to exercise judgment—judgment, that is, in matters not admitting of certainty—balancing probabilities not yet reduced nor even reducible perhaps to calculation; when we reflect that he is called upon to exercise a function analogous to that of the comparative anatomist like Cuvier, comparing theories and doctrines of every degree of similarity and dissimilarity of structure; when, finally, we reflect that he seldom deals with a single idea at a tune, but is for the most part engaged in wielding organized hosts of them, as a general wields at once the division of an army or as a great civil administrator directs from his central office diverse and scattered but related groups of interests and operations; then, I say, the current opinion that devotion to mathematics unfits the devotee for practical affairs should be known for false on a priori grounds. And one should be thus prepared to find that as a fact Gaspard Monge, creator of descriptive geometry, author of the classic Applications de l’analyse à la géométrie; Lazare Carnot, author of the celebrated works, Géométrie de position, and Réflections sur la Métaphysique du Calcul infinitesimal; Fourier, immortal creator of the Théorie analytique de la chaleur; Arago, rightful inheritor of Monge’s chair of geometry; Poncelet, creator of pure projective geometry; one should not be surprised, I say, to find that these and other mathematicians in a land sagacious enough to invoke their aid, rendered, alike in peace and in war, eminent public service.
Science is no longer what one man says. The likes of Newton, Pascal and Einstein may live again. But the need for intense specialization has combined with the need for huge facilities to make group work imperative. Los Alamos, Brookhaven, and the Institute for Advanced Studies are symbols of the change. The world of science is no longer a world of lonely geniuses. It is a collection of communities.
