Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man.

Beware of thinkers whose minds function only when they are fueled by a quotation.

If we merely wait for the appropriate moment we will never live to see it, because this [appropriate moment] cannot arrive without the subjective conditions of the maturity of the revolutionary force being fulfilled - it can only arrive after a series of failed attempts.

Being nimble and light-footed, his father encouraged him to run in the Olympic race. "Yes," said he, "if there were any kings there to run with me."

We regret not having the courage to make such and such decision; we regret much more having made one - any one. Better no action than the consequences of an action.

Why count the days, when even one days is enough for a man to know all happiness?

There is a kind of selective memory that afflicts men when they view the past. They see the good and overlook the evil.

Whatever crushes individuality is despotism, by whatever name it may be called, and whether it professes to be enforcing the will of God or the injunctions of men.

A bad review is even less important than whether it is raining in Patagonia.

Dispersed as the Jews are, they still form one nation, foreign to the land they live in.

It is only he who is possessed of the most complete sincerity that can exist under heaven, who can give its full development to his nature. Able to give its full development to his own nature, he can do the same to the nature of other men. Able to give its full development to the nature of other men, he can give their full development to the natures of animals and things. Able to give their full development to the natures of creatures and things, he can assist the transforming and nourishing powers of Heaven and Earth. Able to assist the transforming and nourishing powers of Heaven and Earth, he may with Heaven and Earth form a ternion.

Most of what happens actually is forgotten.

The species with eyes appears suddenly, capriciously as it were, and it is this species which changes the environment by creating its visible aspect. The eye does not come into being because it is needed. Just the contrary; because the eye appears it can henceforth be applied as a serviceable instrument. Each species builds up its stock of useful habits by selecting among, and taking advantage of, the innumerable useless actions which a living being performs out of sheer exuberance.

Children have as much mind to shew that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.

Too many French scholars were the principal authors of the Revolution, too many approved and gave their support so long as the Revolution, like Tarquinius' sceptre, struck down only the tallest heads. Like so many others, they said, It is impossible to make a great revolution without incurring misfortunes. But when a philosopher justifies evil by the end in view, when he says in his heart, Let there be a hundred thousand murders, provided we are free, and Providence replies, I accept your offer, but you must be included in the number, where is the injustice?

Habit is a second nature.

To a wise man, the whole earth is open; for the native land of a good soul is the whole earth.

The man of principles has character. Of him we know definitely what to expect. He does not act on the basis of his instinct, but on the basis of his will. Therefore, without being redundant one can classify characteristics according to a person's faculty of desire (what is practical), as a) his nature, or natural talent, b) his temperament, or disposition, and c) his general character, or mode of thinking.

Someone arrived there - who lifted the veil of the goddess, at Sais. - But what did he see? He saw - wonder of wonders - himself. Novalis here alludes to Plutarch's account of the shrine of the goddess Minerva, identified with Isis, at Sais, which he reports had the inscription "I am all that hath been, and is, and shall be; and my veil no mortal has hitherto raised."

The methods of logical procedure are very different in ancient and modem logic, but behind all difference is the construction of a universally valid order of thought, neutral with respect to material content. Long before technological man and technological nature emerged as the objects of rational control and calculation, the mind was made susceptible to abstract generalization. Terms which could be organized into a coherent logical system, free from contradiction or with manageable contradiction, were separated from those which could not. Distinction was made between the universal, calculable, "objective" and the particular, incalculable, subjective dimension of thought.

History is full of religious wars; but, we must take care to observe, it was not the multiplicity of religions that produced these wars, it was the intolerating spirit which animated that one which thought she had the power of governing.

We are living even now among punishments and ruins.

There is only one purpose to which a whole society can be directed by a deliberate plan. That purpose is war, and there is no other.

How can great minds be produced in a country where the test of a great mind is agreeing in the opinions of small minds?

A reasonable naturalist then settles down to this life with a sort of animal satisfaction. As Chinese illiterate women put it, "Others gave birth to us and we give birth to others. What else are we to do?".... Life becomes a biological procession and the very question of immortality is sidetracked. For that is the exact feeling of a Chinese grandfather holding his grandchild by the hand and going to the shops to buy some candy, with the thought that in five or ten years he will be returning to his grave or to his ancestors. The best that we can hope for in this life is that we shall not have sons and grandsons of whom we need to be ashamed.

To read is to let someone else work for you - the most delicate form of exploitation.

He who is not sure of his memory, should not undertake the trade of lying. 

Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.

The human soul has need of consented obedience and of liberty. Consented obedience is what one concedes to an authority because one judges it to be legitimate. It is not possible in relation to a political power established by conquest or coup d'etat nor to an economic power based upon money. Liberty is the power of choice within the latitude left between the direct constraint of natural forces and the authority accepted as legitimate. The latitude should be sufficiently wide for liberty to be more than a fiction, but it should include only what is innocent and should never be wide enough to permit certain kinds of crime.

We are constantly railing against the passions; we ascribe to them all of man's afflictions, and we forget that they are also the source of all his pleasures ... But what provokes me is that only their adverse side is considered ... and yet only passions, and great passions, can raise the soul to great things. Without them there is no sublimity, either in morals or in creativity. Art returns to infancy, and virtue becomes small-minded.

The evil of totalitarianism is not only that it fails to protect specific liberties but that it extinguishes the very possibility of freedom.

Obsolescence is the moment of superabundance.

We should provide in peace what we need in war.

Tell me what to avoid, what to seek, by what studies to strengthen my tottering mind, how I may rebuff the waves that strike me abeam and drive me from my course, by what means I may be able to cope with all my evils, and by what means I can be rid of the calamities that have plunged in upon me and those into which I myself have plunged. Teach me how to bear the burden of sorrow without a groan on my part, and how to bear prosperity without making others groan; also, how to avoid waiting for the ultimate and inevitable end, and to beat a retreat of my own free will, when it seems proper to me to do so.

The fact is he made a prodigious blunder in commencing the attack, and now his only chance is to be silent and let people forget the exposure. I do not believe that in the whole history of science there is a case of any man of reputation getting himself into such a contemptible position.

There are two kinds of means. One kind is external to that which is accomplished; the other kind is taken up into the consequences and remains immanent in them. There are ends which are merely welcome cessations and there are ends that are fulfillments of what went before. The toil of the laborer is too often an antecedent to the wage he receives, as consumption of gasoline is merely a means to transportation. The means cease to act when the "end" is reached; one would be glad, as a rule, to get the result without having to employ the means. They are but the scaffolding.

Fanaticism consists in redoubling your efforts when you have forgotten your aim.

Every man is fully satisfied that there is such a thing as truth, or he would not ask any question.

It's almost impossible to say anything against Islam in this country, because you are accused of being racist or Islamophobic.

Behind all appearances, I divine a struggling essence. I want to merge with it. I feel that behind appearances this struggling essence is also striving to merge with my heart. But the body stands between us and separates us. The mind stands between us and separates us.

We need to augment and amend the existing body of classical and neoclassical economic theory to achieve a more realistic picture of economic process.

I really have no claim to rank myself among fatalistic, materialistic, or atheistic philosophers. Not among fatalists, for I take the conception of necessity to have a logical, and not a physical foundation; not among materialists, for I am utterly incapable of conceiving the existence of matter if there is no mind in which to picture that existence; not among atheists, for the problem of the ultimate cause of existence is one which seems to me to be hopelessly out of reach of my poor powers. Of all the senseless babble I have ever had occasion to read, the demonstrations of these philosophers who undertake to tell us all about the nature of God would be the worst, if they were not surpassed by the still greater absurdities of the philosophers who try to prove that there is no God.

A distant enemy is always preferable to one at the gate.

The total possible consciousness may be split into parts which co-exist but mutually ignore each other.

Until he extends the circle of his compassion to all living things, man will not himself find peace.

Solitude, the safeguard of mediocrity, is to genius the stern friend.

He who would write heroic poems should make his whole life a heroic poem.

The world is a perpetual caricature of itself; at every moment it is the mockery and the contradiction of what it is pretending to be.
