We have no reason to fear lest a habit of conscientious inquiry should paralyse the actions of our daily life. But because it is not enough to say, "It is wrong to believe on unworthy evidence," without saying also what evidence is worthy, we shall now go on to inquire under what circumstances it is lawful to believe on the testimony of others; and then, further, we shall inquire more generally when and why we may believe that which goes beyond our own experience, or even beyond the experience of mankind.

In a revolution, as in a novel, the most difficult part to invent is the end.

Men sometimes submit to shame, to tyranny, to conquest, but they never long suffer anarchy. There is no people so barbarous that they escape this general law of humanity.

Society attacks early, when the individual is helpless.

I: My consciousness of the object is only a yet unrecognised consciousness of my production of the representation of an object. Of this production I know no more than that it is I who produce, and thus is all consciousness no more than a consciousness of myself, and so far perfectly comprehensible. Am I in the right? Spirit. Perfectly so ; but whence then is derived the necessity and universality thou hast ascribed to these propositions, to that of causality for instance?

The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings.

One can only live while one is intoxicated with life; as soon as one is sober it is impossible not to see that it is all a mere fraud and a stupid fraud! Ch. 4 Variant: It is possible to live only as long as life intoxicates us; once we are sober we cannot help seeing that it is all a delusion, a stupid delusion.

I have wanted them to have this simple definition to read again and again so they know: Feminism is a movement to end sexism, sexist exploitation, and oppression.

Even the most inspired verse, which boasts not without a relative justification to be immortal, becomes in the course of ages a scarcely legible hieroglyphic; the language it was written in dies, a learned education and an imaginative effort are requisite to catch even a vestige of its original force. Nothing is so irrevocable as mind.

A blow from your friend is better than a kiss from your enemy.

Now, on the contrary, when every one is to cultivate himself into man, condemning a man to machine-like labor amounts to the same thing as slavery. If a factory-worker must tire himself to death twelve hours and more, he is cut off from becoming man. Every labor is to have the intent that the man be satisfied. His labor is nothing taken by itself, has no object in itself, is nothing complete in itself; he labors only into another's hands, and is used (exploited) by this other.

"Young men," said Cæsar, "hear an old man to whom old men hearkened when he was young."

The mind intent upon resolving as well as compounding the concept of a composite demands and presumes boundaries in which it may acquiesce in the former as well as in the latter direction.

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.

Not official revolutionary commissars in any sort of sashes, but rather revolutionary propagandists are to be dispatched into all the provinces and communes and particularly among the peasants who cannot be revolutionised by principles, nor by the decrees of any dictatorship, but only by the act of revolution itself, that is to say, by the consequences that will inevitably ensure in every commune from complete cessation of the legal and official existence of the state.

To rule the imperial population, behold our vocation.

It is requisite to defend those who are unjustly accused of having acted injuriously, but to praise those who excel in a certain good.

It is of great importance to observe that the character of every man is, in some degree, formed by his profession. A man of sense may only have a cast of countenance that wears off as you trace his individuality, whist the weak, common man has scarcely ever any character, but what belongs to the body; at least, all his opinions have been so steeped in the vat consecrated by authority, that the faint spirit which the grape of his own vine yields, cannot be distinguished.

The antithesis of 'Sense' & 'Ideas' is the foundation of the Philosophy of Science. No knowledge can exist without the union, no philosophy without the separation, of these two elements.

Philosophy and religion are enemies, and because they are enemies they have need of one another. There is no religion without some philosophical basis, no philosophy without roots in religion. ... the attacks which are directed against religion from a presumed scientific or philosophical point of view are merely attacks from another but opposing religious point of view.

Capitalism has brought about the emancipation of collective humanity with respect to nature. But this collective humanity has itself taken on with respect to the individual the oppressive function formerly exercised by nature.

Man is forming thousands of ridiculous relations between himself and God.

The empirical research of the last fifteen years on the structure of large organizations seems to confirm the hypothesis of Herbert Simon that human cognitive limits are a basic limiting factor in determining organization structures .

And truly... if men could be persuaded to mind more the advancement of natural philosophy than that of their own reputations, it were not, methinks, very uneasy to make them sensible, that one of the considerablest services, that they could do mankind, were to set themselves diligently and industriously to make experiments and collect observations, without being over-forward to establish principles and axioms, believing it uneasy to erect such theories, as are capable to explicate all the phænomena of nature, before they have been able to take notice of the tenth part of those phænomena, that are to be explicated.

The career a young man should choose should be one that is most consonant with our dignity, one that is based on ideas of whose truth we are wholly convinced, one that offers us largest scope in working for humanity and approaching that general goal towards which each profession offers only one of the means: the goal of perfection ... If he works only for himself he can become a famous scholar, a great sage, an excellent imaginative writer [Dichter], but never a perfected, a truly great man.

The truth is always in the minority, and the minority is always stronger than the majority, because as a rule the minority is made up of those who actually have an opinion, while the strength of the majority is illusory, formed of that crowd which has no opinion - and which therefore the next moment (when it becomes clear that the minority is the stronger) adopts the latter's opinion, which now is in the majority, i.e. becomes rubbish by having the whole retinue and numerousness on its side, while the truth is again in a new minority.

...to the question whether or not the motion of the Earth in space can be made perceptible in terrestrial experiments. We have already remarked... that all attempts of this nature led to a negative result. Before the theory of relativity was put forward, it was difficult to become reconciled to this negative result.

I never lose an opportunity of urging a practical beginning, however small, for it is wonderful how often in such matters the mustard-seed germinates and roots itself.

A straightforward, honest person should be like someone who stinks: when you're in the same room with him, you know it.

It is the greatest of all mistakes to do nothing because you can only do little.

The same good sense, that directs men in the ordinary occurrences of life, is not hearkened to in religious matters, which are supposed to be placed altogether above the cognizance of human reason.

Better to have beasts that let themselves be killed than men who run away.

His disciples said to Him, "When will the Kingdom come?" Jesus said, "It will not come by waiting for it. It will not be a matter of saying 'Here it is' or 'There it is.' Rather, the Kingdom of the Father is spread out upon the earth, and men do not see it."

Altogether, Jesus never behaves like a man wandering in a system of delusions. He reacts in absolutely normal fashion to what is said to Him, and to the events that concern Him. He is never out of touch with reality.

The camera is as subjective as we are.

Philosophy is by its nature something esoteric, neither made for the mob nor capable of being prepared for the mob.

Prejudices are so to speak the mechanical instincts of men: through their prejudices they do without any effort many things they would find too difficult to think through to the point of resolving to do them.

I was not the one to invent lies: they were created in a society divided by class and each of us inherited lies when we were born. It is not by refusing to lie that we will abolish lies: it is by eradicating class by any means necessary.

Lifetime is a child at play, moving pieces in a game.

If God did not exist, it would be necessary to invent him.

But the truth is that my work - I was going to say my mission - is to shatter the faith of men here, there, and everywhere, faith in affirmation, faith in negation, and faith in abstention in faith, and this for the sake of faith in faith itself; it is to war against all those who submit, whether it be to Catholicism, or to rationalism, or to agnosticism; it is to make all men live the life of inquietude and passionate desire.

Her face seems ravaged by both lightning and hail. But on yours there is something like the promise of a storm: one day passion will burn it to the bone.

No position is so false as having understood and still remaining alive.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

You need only look around you, replied PHILO, to satisfy yourself with regard to this question. A tree bestows order and organisation on that tree which springs from it, without knowing the order; an animal in the same manner on its offspring; a bird on its nest; and instances of this kind are even more frequent in the world than those of order, which arise from reason and contrivance. To say, that all this order in animals and vegetables proceeds ultimately from design, is begging the question; nor can that great point be ascertained otherwise than by proving, a priori, both that order is, from its nature, inseparably attached to thought; and that it can never of itself, or from original unknown principles, belong to matter.

I cannot read a sentence in the book of the Hindoos without being elevated as upon the table-land of the Ghauts. It has such a rhythm as the winds of the desert, such a tide as the Ganges, and seems as superior to criticism as the Himmaleh Mounts. Even at this late hour, unworn by time with a native and inherent dignity it wears the English dress as indifferently as the Sanscrit.
