That the sun will not...

That the sun will not rise to-morrow is no less intelligible a proposition, and implies no contradiction, than the affirmation, that it will rise.

Man has to awaken to wonder — and so perhaps do peoples. Science is a way of sending him to sleep again.

Science as a system of...

Science as a system of statements is always an object of discussion. Statements are to be compared with statements, and not with 'experience', or with 'the world', or with something else. All that meaningless doubling belongs to more or less subtle metaphysics and as such must be rejected. Every new statement is to be confronted with existing ones, already brought to a state of harmony between themselves. A statement will be considered correct if it can be joined to them.

Mill, in speaking of Hume's...

Mill, in speaking of Hume's celebrated principle, "that nothing is credible which is contradictory to experience, or at variance with the laws of nature," calls it a very plain and harmless proposition, being, in effect, nothing more than that whatever is contradictory to a complete induction is incredible. Admit the existence of a Deity, and the possibility of a miracle is the natural consequence. No doubt our examination of the evidence which sustains an unusual phenomenon should be most carefully conducted; but we must not measure the credibility or incredibility of an event by the narrow sphere of our own experience, nor forget that there is a Divine energy which overrides what we familiarly call the laws of nature.

They [the wise spirits of antiquity in the first circle of Dante's Inferno] are condemned, Dante tells us, to no other penalty than to live in desire without hope, a fate appropriate to noble souls with a clear vision of life.

There is the same difference...

There is the same difference between political theory and constitutional laws as there is between poetics and poetry. The illustrious Montesquieu is to Lycurgus, in the intellectual hierarchy, what Batteux is to Homer or Racine. Moreover, these two talents positively exclude each other, as can be seen by the example of Locke, who fumbled badly when he presumed to give laws to the Americans.

It is a very comfortable...

It is a very comfortable reflection to the lovers of liberty, that this peculiar privilege of Britain is of a kind that cannot easily be wrested from us, but must last as long as our government remains, in any degree, free and independent. It is seldom, that liberty of any kind is lost all at once. Slavery has so frightful an aspect to men accustomed to freedom, that it must steal upon them by degrees, and must disguise itself in a thousand shapes, in order to be received. But, if the liberty of the press ever be lost, it must be lost at once. The general laws against sedition and libelling are at present as strong as they possibly can be made. Nothing can impose a farther restraint, but either the clapping an Imprimatur upon the press, or the giving to the court very large discretionary powers to punish whatever displeases them. But these concessions would be such a bare-faced violation of liberty, that they will probably be the last efforts of a despotic government. We may conclude, that the liberty of Britain is gone for ever when these attempts shall succeed.

I believe that one of the things Christianity says is that sound doctrines are all useless. That you have to change your life. (Or the direction of your life.)

Or, to go a step...

Or, to go a step further, let us glance at what science has done to establish rational foundations for physical and moral health. Science tells us how we ought to live in order to preserve the health of our own bodies, how to maintain in good conditions of existence the crowded masses of our population. But does not all the vast amount of work done in these two directions remain a dead letter in our books? We know it does. And why? Because science today exists only for a handful of privileged persons, because social inequality which divides society into two classes — the wage-slaves and the grabbers of capital — renders all its teachings as to the conditions of a rational existence only the bitterest irony to nine-tenths of mankind.

A philosopher may try to prove the truth of something he believed before he was a philosopher, but even if he succeeds, his belief never regains the untroubled character, and the settled place in his mind, which it had at first.

There is a great analogy between grace and genius, for genius is a grace. The real man of genius is the one who acts by grace or by impulsion, without ever contemplating himself and without ever saying to himself: Yes! It is by grace that I act.

If the material world rests...

If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world. By supposing it to contain the principle of its order within itself, we really assert it to be God; and the sooner we arrive at that Divine Being, so much the better. When you go one step beyond the mundane system, you only excite an inquisitive humour which it is impossible ever to satisfy.

A society to which preestablished...

A society to which preestablished forms, crystallized by law, are repugnant; which looks for harmony in an ever-changing and fugitive equilibrium between a multitude of varied forces and influences of every kind, following their own course, — these forces promoting themselves the energies which are favorable to their march toward progress, toward the liberty of developing in broad daylight and counter-balancing one another.This conception and ideal of society is certainly not new. On the contrary, when we analyze the history of popular institutions — the clan, the village community, the guild and even the urban commune of the Middle Ages in their first stages, — we find the same popular tendency to constitute a society according to this idea...

The means of production being...

The means of production being the collective work of humanity, the product should be the collective property of the race. Individual appropriation is neither just nor serviceable. All belongs to all. All things are for all men, since all men have need of them, since all men have worked in the measure of their strength to produce them, and since it is not possible to evaluate every one's part in the production of the world's wealth. All things are for all. Here is an immense stock of tools and implements; here are all those iron slaves which we call machines, which saw and plane, spin and weave for us, unmaking and remaking, working up raw matter to produce the marvels of our time. But nobody has the right to seize a single one of these machines and say, "This is mine; if you want to use it you must pay me a tax on each of your products," any more than the feudal lord of medieval times had the right to say to the peasant, "This hill, this meadow belong to me, and you must pay me a tax on every sheaf of corn you reap, on every rick you build." All is for all! If the man and the woman bear their fair share of work, they have a right to their fair share of all that is produced by all, and that share is enough to secure them well-being. No more of such vague formulas as "The Right to work," or "To each the whole result of his labour." What we proclaim is The Right to Well-Being: Well-Being for All!

Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.

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.

I tell you that if...

I tell you that if natural bodies have it from Nature to be moved by any movement, this can only be circular motion, nor is it possible that Nature has given to any of its integral bodies a propensity to be moved by straight motion. I have many confirmations of this proposition, but for the present one alone suffices, which is this. I suppose the parts of the universe to be in the best arrangement, so that none is out of its place, which is to say that Nature and God have perfectly arranged their structure. This being so, it is impossible for those parts to have it from Nature to be moved in straight, or in other than circular motion, because what moves straight changes place, and if it changes place naturally, then it was at first in a place preternatural to it, which goes against the supposition. Therefore, if the parts of the world are well ordered, straight motion is superfluous and not natural, and they can only have it when some body is forcibly removed from its natural place, to which it would then return by a straight line, for thus it appears that a part of the earth does [move] when separated from its whole. I said "it appears to us," because I am not against thinking that not even for such an effect does Nature make use of straight line motion.

All this wonderful culture has...

All this wonderful culture has entirely developed in the second half of the nineteenth century. Before that, it was quite primitive. But now the Paris gardener not only defies the soil—he would grow the same crops on an ashphalt pavement—he defies the climate. His walls, which are built to reflect light and to protect the wall-trees from the northern winds, his wall-tree shades and glass protectors, his frames and pépinières have made a real garden, a rich Southern garden, out of the suburbs of Paris. He has given to Paris the 'two degrees less of latitude' after which a French scientific writer was longing; he supplies his city with mountains of grapes and fruit at any season; and in the early spring he inundates and perfumes it with flowers. But he does not only grow articles of luxury. The culture of plain vegetables on a large scale is spreading every year; and the results are so good that there are now practical maraîchers who venture to maintain that if all the food, animal and vegetable, necessary for 4,500,000 inhabitants of the departments of Seine and had to be grown in their own territory (3,520 square miles), it could be grown without resorting to any other methods of culture than those already in use—methods already tested on a large scale and proved to be successful.

There is no information about the thingness of the thing without knowledge of the kind of truth in which the thing stands. But there is no information about this truth of the thing without knowledge of the thingness of the thing whose truth is in question. Where are we to get a foothold? The ground slips away under us. Perhaps we are already close to falling into the well. At any rate the housemaids are already laughing. p. 27

Despair is like forward children, who, when you take away one of their playthings, throw the rest into the fire for madness. It grows angry with itself, turns its own executioner, and revenges its misfortunes on its own head.

There are three basic problems: how a mind can know the world of nature, how it is possible for one mind to know another, and how it is possible to know the contents of our own minds without resort to observation or evidence. It is a mistake, I shall urge, to suppose that these questions can be collapsed into two, or taken into isolation.

In fact, this infinitesimally spread-out consciousness is a direct feeling of its contents as spread out. In an infinitesimal interval we directly perceive the temporal sequence of its beginning, middle, and end... Now upon this interval follows another, whose beginning is the middle of the former, and whose middle is the end of the former. Here we have an immediate perception of the temporal sequence of its beginning, middle and end, or say, of the second, third, and fourth instants.

One should not be deceived by philosophical works that pretend to be mathematical, but are merely dubious and murky metaphysics. Just because a philosopher can recite the words lemma, theorem and corollary doesn't mean that his work has the certainty of mathematics. That certainty does not derive from big words, or even from the method used by geometers, but rather from the utter simplicity of the objects considered by mathematics.

At this point in history...

At this point in history when all things which concern man and the structure and elements of history itself are suddenly revealed to us in a new light, it behooves us in our scientific thinking to become masters of the situation, for it is not inconceivable that sooner than we suspect, as has often been the case before in history, this vision may disappear, the opportunity may be lost, and the world will once again present a static, uniform, and inflexible countenance.

Be it understood, then, that...

Be it understood, then, that what we have to do, as students of phenomenology, is simply to open our mental eyes and look well at the phenomenon and say what are the characteristics that are never wanting in it, whether that phenomenon be something that outward experience forces upon our attention, or whether it be the wildest of dreams, or whether it be the most abstract and general of the conclusions of science. The faculties which we must endeavor to gather for this work are three. The first and foremost is that rare faculty, the faculty of seeing what stares one in the face, just as it presents itself, unreplaced by any interpretation, unsophisticated by any allowance for this or for that supposed modifying circumstance. This is the faculty of the artist who sees for example the apparent colors of nature as they appear. When the ground is covered by snow on which the sun shines brightly except where shadows fall, if you ask any ordinary man what its color appears to be, he will tell you white, pure white, whiter in the sunlight, a little greyish in the shadow. But that is not what is before his eyes that he is describing; it is his theory of what ought to be seen. The artist will tell him that the shadows are not grey but a dull blue and that the snow in the sunshine is of a rich yellow. That artist's observational power is what is most wanted in the study of phenomenology. The second faculty we must strive to arm ourselves with is a resolute discrimination which fastens itself like a bulldog upon the particular feature that we are studying, follows it wherever it may lurk, and detects it beneath all its disguises. The third faculty we shall need is the generalizing power of the mathematician who produces the abstract formula that comprehends the very essence of the feature under examination purified from all admixture of extraneous and irrelevant accompaniments.

The reason I cannot really...

The reason I cannot really say that I positively enjoy nature is that I do not quite realize what it is that I enjoy. A work of art, on the other hand, I can grasp. I can — if I may put it this way — find that Archimedian point, and as soon as I have found it, everything is readily clear for me. Then I am able to pursue this one main idea and see how all the details serve to illuminate it.

I come now to another...

I come now to another part of my system, and because it suggests a lofty idea of the plan of creation, it appears to me as the most seductive. The sequence of ideas that led us to it is very simple and natural. They are as follows: let us imagine a system of stars gathered together in a common plane, like those of the Milky Way, but situated so far away from us that even with the telescope we cannot distinguish the stars composing it; let us assume that its distance, compared to that separating us from the stars of the Milky Way, is the same proportion as the Milky Way is to the distance from the earth to the sun; such a stellar world will appear to the observer, who contemplates it at so enormous a distance, only as a little spot feebly illumined and subtending a very small angle; its shape will be circular, if its plane is perpendicular to the line of sight, elliptical, if it is seen obliquely. The faintness of its light, its form, and its appreciable diameter will obviously distinguish such a phenomenon from the isolated stars around it.We do not need to seek far in the observations of astronomers to meet with such phenomena. They have been seen by various observers, who have wondered at their strange appearance, have speculated about them, and have suggested some times the most amazing explanations, sometimes theories which were more rational, but which had no more foundation than the former. We refer to the nebulæ, or, more precisely, to a particular kind of celestial body which M. de Maupertius describes as follows:"These are small luminous patches, only slightly more brilliant than the dark background of the sky; they have this in common, that their shapes are more or less open elipses; and their light is far more feeble than that of any other objects to be perceived in the heavens."...It is much more natural and reasonable to assume that a nebula is not a unique and solitary sun, but a system of numerous suns, which appear crowded, because of their distance, into a space so limited that their light, which would be imperceptible were each of them isolated, suffices, owing to their enormous numbers, to give a pale and uniform luster. Their analogy with our own system of stars; their form, which is precisely what it should be according to our theory; the faintness of their light, which denotes an infinite distance; all are in admirable accord and lead us to consider these elliptical spots as systems of the same order as our own—in a word, to be Milky Ways similar to the one whose constitution we have explained. And if these hypotheses, in which analogy and observation consistently lend mutual support, have the same merit as formal demonstrations, we must consider the existence of such systems as demonstrated...We see that scattered through space out to infinite distances, there exist similar systems of stars [nebulous stars, nebulæ], and that creation, in the whole extent of its infinite grandeur, is everywhere organized into systems whose members are in relation with one another.... A vast field lies open to discoveries, and observations alone will give the key.
