Woe to the book you can read without constantly wondering about the author!

If you make the same guess often enough it ceases to be a guess and becomes a Scientific Fact. This is the inductive method.

Every peasant has a lawyer inside of him, just as every lawyer, no matter how urbane he may be, carries a peasant within himself.

"I do not know whether behind appearances there lives and moves a secret essence superior to me. Nor do I ask; I do not care. I create phenomena in swarms, and paint with a full palette a gigantic and gaudy curtain before the abyss. Do not say, "Draw the curtain that I may see the painting." The curtain is the painting.

Men can be provincial in time, as well as in place.

If conquest constitutes a natural right on the part of the few, the many have only to gather sufficient strength in order to acquire the natural right of reconquering what has been taken from them.

The poor maidservant who used to say that she only believed in God when she had a toothache puts all theologians to shame.

A robot, the man had said, is logical but not reasonable.

Every other art,-as poetry, music, painting,-may be practised without the process showing forth the rules according to which it is conducted ;-but in the self-cognizant art of the philosopher, no step can be taken without declaring the grounds upon which it proceeds.

The progressive world is necessarily divided into two classes - those who take the best of what there is and enjoy it - those who wish for something better and try to create it. Without these two classes the world would be badly off. They are the very conditions of progress, both the one and the other. Were there none who were discontented with what they have, the world would never reach anything better.

The man who holds the divine theory of life recognizes life not in his own individuality, and not in societies of individualities (in the family, the clan, the nation, the tribe, or the government), but in the eternal undying source of life-in God; and to fulfill the will of God he is ready to sacrifice his individual and family and social welfare. The motor power of his life is love. And his religion is the worship in deed and in truth of the principle of the whole-God.

We came to a tree which was still bare, and on which the birds were singing out gaily in the morning, without any fear of us. Then stooping over like an Indian on the hunt, my companion placed a pebble in the leather of his sling and stretched it. Obeying his peremptory glance I did the same, with frightful twinges of conscience, vowing firmly that I would shoot when he did. At that very moment the church bells began to sound, mingling with the song of the birds in the sunshine. It was the warning bell that came a half-hour before the main bell. For me it was a voice from heaven. I threw the sling down, scaring the birds away, so that they were safe from my companion's sling, and fled home. And ever afterwards when the bells of Holy Week ring out amidst the leafless trees in the sunshine I remember with moving gratitude how they rang into my heart at that time the commandment: Thou shalt not kill.

Men accept servility in order to acquire wealth; as if they could acquire anything of their own when they cannot even assert that they belong to themselves.

Alexander, king of Macedon, began to study geometry; unhappy man, because he would thereby learn how puny was that earth of which he had seized but a fraction! Unhappy man, I repeat, because he was bound to understand that he was bearing a false title. For who can be "great" in that which is puny?

When the act of navigation was made, though England and Holland were not actually at war, the most violent animosity subsisted between the two nations. ... It is not impossible, therefore, that some of the regulations of this famous act may have proceeded from national animosity. They are as wise, however, as if they had all been dictated by the most deliberate wisdom. National animosity at that particular time aimed at the very same object which the most deliberate wisdom would have recommended, the diminution of the naval power of Holland, the only naval power which could endanger the security of England.

From the moment when labour can no longer be converted into capital, money, or rent, into a social power capable of being monopolized, i.e., from the moment when individual property can no longer be transformed into bourgeois property, into capital, from that moment, you say individuality vanishes.

People talk sometimes of bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel.

There is not a negro from the coast of Africa who does not, in this respect, possess a degree of magnanimity which the soul of his sordid master is too often scarce capable of conceiving. Fortune never exerted more cruelly her empire over mankind, than when she subjected those nations of heroes to the refuse of the jails of Europe, to wretches who possess the virtues neither of the countries which they come from, nor of those which they go to, and whose levity, brutality, and baseness, so justly expose them to the contempt of the vanquished.

When a philosopher addresses himself to... a tyrant, and tells him... tyranny is incompatible with justice, then the philosopher speaks... and believes he is speaking the truth, and... takes a risk...

Whether directly or indirectly all nations are originally nothing but Indian colonies... the oriental antiquity could, if we consented to deepen it, bring us back more safely towards the divine....

He was a man who looked at what ought to be done, not to the reputation which is got by a man's acts.

The Church is now more like the Scribes and Pharisees than like Christ... What are now called the "essential doctrines" of the Christian religion he does not even mention.

War as the most extreme political means discloses the possibility which underlies every political idea, namely, the distinction of friend and enemy.

Here is a fulfillment of long centuries of civilization and culture; here, in romantic love, more than the triumph of thought or the victories of power is the topmost reach of human beings.

To know what you prefer, instead of humbly saying Amen to what the world tells you you ought to prefer, is to have kept your soul alive.

Opinion considers the opposition of what is true and false quite rigid, and, confronted with a philosophical system, it expects agreement or contradiction. And in an explanation of such a system, opinion still expects to find one or the other.

Whatever can be done another day can be done today.

Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

Eloquence may strike the ear, but the language of poverty strikes the heart; the first may charm like music, but the second alarms like a knell. 

I think people who are unhappy are always proud of being so, and therefore do not like to be told that there is nothing grand about their unhappiness. A man who is melancholy because lack of exercise has upset his liver always believes that it is the loss of God, or the menace of Bolshevism, or some such dignified cause that makes him sad. When you tell people that happiness is a simple matter, they get annoyed with you.

It is truly a marvelous thing to consider to what greatness Athens arrived in the space of one hundred years after she freed herself from the tyranny of Pisistratus; but, above all, it is even more marvelous to consider the greatness Rome reached when she freed herself from her kings. The reason is easy to understand, for it is the common good and not private gain that makes cities great. Yet, without a doubt, this common good is observed only in republics, for in them everything that promotes it is practised, and however much damage it does to this or that private individual, those who benefit from the said common good are so numerous that they are able to advance in spite of the inclination of the few citizens who are oppressed by it.

If we do not return to the old maxims, if education is not restored into the hands of priests, and if science is not every where placed in the second rank, the evils which await us are incalculable: we shall become brutalized by science, and this is the lowest degree of brutality.

Every emancipation is a restoration of the human world and of human relationships to a man himself.

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.

Why then do you occupy me with the words rather than with the works of wisdom? Make me braver, make me calmer, make me the equal of Fortune, make me her superior.

A harmonious being cannot believe in God. Saints, criminals, and paupers have launched him, making him available to all unhappy people.

The only good that I can see in the demonstration of the truth of "Spiritualism" is to furnish an additional argument against suicide. Better live a crossing-sweeper than die and be made to talk twaddle by a "medium" hired at a guinea a séance.

Only the most perfect human being can design the most perfect philosophy.

Love's great (and sole) originality is to make happiness indistinct from misery.

Our questions and answers are in part determined by the historical tradition in which we find ourselves. We apprehend truth from our own source within the historical tradition. The content of our truth depends upon our appropriating the historical foundation. Our own power of generation lies in the rebirth of what has been handed down to us. If we do not wish to slip back, nothing must be forgotten; but if philosophising is to be genuine our thoughts must arise from our own source. Hence all appropriation of tradition proceeds from the intentness of our own life. The more determinedly I exist, as myself, within the conditions of the time, the more clearly I shall hear the language of the past, the nearer I shall feel the glow of its life.

We tend to believe the premises because we can see that their consequences are true, instead of believing the consequences because we know the premises to be true. But the inferring of premises from consequences is the essence of induction; thus the method in investigating the principles of mathematics is really an inductive method, and is substantially the same as the method of discovering general laws in any other science.

We shall, therefore, assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.

When people are friends, they have no need of justice, but when they are just, they need friendship in addition.

The equal right of all men to the use of land is as clear as their equal right to breathe the air - it is a right proclaimed by the fact of their existence. For we cannot suppose that some men have a right to be in this world, and others no right.

One can only become a philosopher, but not be one. As one believes he is a philosopher, he stops being one.

The deceiver is really the fool.

While it is in no way racist for any author to write a book exclusively about white women, it is fundamentally racist for books to be published that focus solely on the American white woman's experience in which that experience is assumed to be the American woman's experience.
