Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

As regards the objection that possibles are independent of the decrees of God I grant it of actual decrees (although the Cartesians do not at all agree to this), but I maintain that the possible individual concepts involve certain possible free decrees; for example, if this world was only possible, the individual concept of a particular body in this world would involve certain movements as possible, it would also involve the laws of motion, which are the free decrees of God; but these, also, only as possibilities. Because, as there are an infinity of possible worlds, there are also an infinity of laws, certain ones appropriate to one; others, to another, and each possible individual of any world involves in its concept the laws of its world.

False opinions are like false money, struck first of all by guilty men and thereafter circulated by honest people who perpetuate the crime without knowing what they are doing. Original text:Les fausses opinions ressemblent à la fausse monnaie qui est frappée d'abord par de grands coupables et dépensée ensuite par d'honnêtes gens qui perpétuent le crime sans savoir ce qu'ils font.

Pride costs us more than hunger, thirst and cold.

The most human thing about us is our technology.

Beginning to reason is like stepping onto an escalator that leads upward and out of sight. Once we take the first step, the distance to be traveled is independent of our will and we cannot know in advance where we shall end.

One of the problems... both on the left and the right is that the... individual autonomy protected by liberalism tends to take more and more extreme versions... and... becomes self-undermining.

Our English careers to born genius are twofold. There is the silent or unlearned career of the Industrialisms, which are very many among us; and there is the articulate or learned career of the three professions, Medicine, Law (under which we may include Politics), and the Church. Your born genius, therefore, will first have to ask himself, Whether he can hold his tongue or cannot? True, all human talent, especially all deep talent, is a talent to do, and is intrinsically of silent nature; inaudible, like the Sphere Harmonies and Eternal Melodies, of which it is an incarnated fraction.

The idea of living beings as subject to 'disease' includes a recognition of a Final Cause in organization; for disease is a state in which the vital forces do not attain their 'proper ends'.

Death is the only thing we haven't succeeded in completely vulgarizing.

Contemplating the universe, the whole system of creation, in this point of light, we shall discover, that all that which is called natural philosophy is properly a divine study- It is the study of God through his works - It is the best study, by which we can arrive at a knowledge of the existence, and the only one by which we can gain a glimpse of his perfection. Do we want to contemplate his power? We see it in the immensity of the Creation. Do we want to contemplate his wisdom? We see it in the unchangeable order by which the incomprehensible Whole is governed. Do we want to contemplate his munificence? We see it in the abundance with which he fills the earth. Do we want to contemplate his mercy? We see it in his not withholding that abundance even from the unthankful. In fine, do we want to know what God is?

Nothing is great but truth, and the smallest truth is great. The other day I had a thought, which I put like this: Even a harmful truth is useful, for it can be harmful only for the moment and will lead to other truths, which must always become useful, very much so. Conversely, even a useful error is harmful, for it can be useful only for the moment, enticing us into other errors, which become more and more harmful.

Such religion as there can be in modern life, every individual will have to salvage from the churches for himself.

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.

It seems to me, that if the matter of our sun and planets and all the matter of the universe, were evenly scattered throughout all the heavens, and every particle had an innate gravity towards all the rest, and the whole of space throughout which this matter was scattered was but finite, the matter on [toward] the outside of this space would, by its gravity, tend towards all the matter on the inside, and, by consequence, fall down into the middle of the whole space, and there compose one great spherical mass. But if the matter was evenly disposed throughout an infinite space it could never convene into one mass; but some of it would convene into one mass and some into another, so as to make an infinite number of great masses, scattered at great distances from one another throughout all that infinite space.

It has always been denied by the republican party in this country, that the Constitution had given the power of incorporation to Congress. On the establishment of the Bank of the United States, this was the great ground on which that establishment was combated; and the party prevailing supported it only on the argument of its being an incident to the power given them for raising money.

Who would govern that can get along without governing? He that is fittest for it, is of all men the unwillingest unless constrained.

In comparing civilized man with the animal world, one is as the Alpine traveller, who sees the mountains soaring into the sky and can hardly discern where the deep shadowed crags and roseate peaks end, and where the clouds of heaven begin. Surely the awe-struck voyager may be excused if, at first, he refuses to believe the geologist, who tells him that these glorious masses are, after all, the hardened mud of primeval seas, or the cooled slag of subterranean furnaces-of one substance with the dullest clay, but raised by inward forces to that place of proud and seemingly inaccessible glory. But the geologist is right; and due reflection on his teachings, instead of diminishing our reverence and our wonder, adds all the force of intellectual sublimity, to the mere aesthetic intuition of the uninstructed beholder.

The covetous man is ever in want.

Fear not, then, thou child infirm, There's no god dare wrong a worm.

It is a consolation to the wretched to have companions in misery.

When one is not understood one should as a rule lower one's voice, because when one really speaks loudly enough and is not heard, it is because people do not want to hear. One had better begin to mutter to oneself, then they get curious.

You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.

I have cast fire upon the world, and see, I am guarding it until it blazes.

It is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.

Remember that the term Rational was intended to signify a discriminating attention to every several thing and freedom from negligence; and that Equanimity is the voluntary acceptance of things which are assigned to thee by the common nature; and the Magnanimity is the elevation of the intelligent part above the pleasurable or painful sensations of the flesh, and above that poor thing called fame, and death, and all such things. If then, thou maintainest thyself in the possession of these names, without desiring to be called by these names by others, thou wilt be another person and wilt enter into another life.

As soon as one returns to Doubt (if it could be said that one has ever left it), undertaking anything at all seems not so much useless as extravagant. Doubt works deep within you like a disease, or even more effectively, like a faith.

She is rightly called not only the mother of the man, but also the Mother of God ... It is certain that Mary is the Mother of the real and true God.

My point is not that everything is bad, but that everything is danger­ous, which is not exactly the same as bad. If everything is dangerous, then we always have something to do. So my position leads not to apa­thy but to a hyper- and pessimistic activism. I think that the ethico-political choice we have to make every day is to determine which is the main danger. "

There is no word or action but has its echo in Eternity. Thought is an Idea in transit, which when once released, never can be lured back, nor the spoken word recalled. Nor ever can the overt act be erased All that thou thinkest, sayest, or doest bears perpetual record of itself, enduring for Eternity.

If you use a trick in logic, whom can you be tricking other than yourself?

It is not calling the landed estates, possessed by old prescriptive rights, the 'accumulations of ignorance and superstition', that can support me in shaking that grand title, which supersedes all other title, and which all my studies of general jurisprudence have taught me to consider as one principal cause of the formation of states; I mean the ascertaining and securing prescription. But these are donations made in 'ages of ignorance and superstition'. Be it so. It proves that these donations were made long ago; and this is prescription; and this gives right and title.

Art can speak its own language only as long as the images are alive which refuse and refute the established order.

"Although," said he [Cato], "all the world has fallen under one man's sway, although Caesar's legions guard the land, his fleets the sea, and Caesar's troops beset the city gates, yet Cato has a way of escape; with one single hand he will open a wide path to freedom. This sword, unstained and blameless even in civil war, shall at last do good and noble service: the freedom which it could not give to his country it shall give to Cato!

We have lost, being born, as much as we shall lose, dying. Everything.

The freedom of the 'everyday mind' consists rather in not kneeling down in awe. Its mental attitude is better expressed as sitting unmoveable like an object.

Every toiling Manchester, its smoke and soot all burnt, ought it not, among so many world-wide conquests, to have a hundred acres or so of free greenfield, with trees on it, conquered, for its little children to disport in; for its all-conquering workers to take a breath of twilight air in? You would say so! A willing Legislature could say so with effect. A willing Legislature could say very many things! And to whatsoever 'vested interest,' or such like, stood up, gainsaying merely, "I shall lose profits,"-the willing Legislature would answer, "Yes, but my sons and daughters will gain health, and life, and a soul."-

Rationality requires a choice among all possible alternative behaviors. In actual behavior, only a very few of all these possible alternatives come to mind.

I should as soon think of swimming across Charles River when I wish to go to Boston, as of reading all my books in originals when I have them rendered for me in my mother tongue.

Those hypotheses do not a little hinder the progress of Humane knowledge, that introduce Morals and Politicks into the Explications of Corporeal Nature, where all things are indeed transacted according to Laws Mechanical.

All men are in need of help and depend on one another. Human solidarity is the necessary condition for the unfolding of any one individual.
