He who says he hates every kind of flattery, and says it in earnest, certainly does not yet know every kind of flattery.

To fall into a habit is to begin to cease to be.

Rules for Definitions. I. Not to undertake to define any of the things so well known of themselves that the clearer terms cannot be had to explain them. II. Not to leave any terms that are at all obscure or ambiguous without definition. III. Not to employ in the definition of terms any words but such as are perfectly known or already explained.

Although it is commonly supposed that war making is the specific activity of nations, the blind rage that motivates war destroys the very social bonds that make nations possible. Of course, it can fortify the nationalism of a nation, producing a provisional coherence bolstered by war and enmity, but it also erodes the social relations that make politics possible. The power of destruction unleashed by war breaks social ties and produces anger, revenge, and distrust ("embitterment") such that it becomes unclear whether reparation is possible, undermining not only those relations that may have been built in the past, but also the future possibility of peaceful coexistence.

Time with its continuity logically involves some other kind of continuity than its own. Time, as the universal form of change, cannot exist unless there is something to undergo change, and to undergo a change continuous in time, there must be a continuity of changeable qualities.

To talk about religion except in terms of human psychology is an irrelevance.

Why does this magnificent applied science which saves work and makes life easier bring us so little happiness? The simple answer runs: Because we have not yet learned to make sensible use of it. In war it serves that we may poison and mutilate each other. In peace it has made our lives hurried and uncertain. Instead of freeing us in great measure from spiritually exhausting labor, it has made men into slaves of machinery, who for the most part complete their monotonous long day's work with disgust and must continually tremble for their poor rations. ... It is not enough that you should understand about applied science in order that your work may increase man's blessings. Concern for the man himself and his fate must always form the chief interest of all technical endeavours; concern for the great unsolved problems of the organization of labor and the distribution of goods in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.

The jingoes and war speculators are filling the air with the sentimental slogan of hypocritical nationalism, "America for Americans," "America first, last, and all the time."

The weapon of criticism obviously cannot replace the criticism of weapons. Material force can only be overthrown by material force, but theory itself becomes a material force when it has gripped the masses. Theory is capable of gripping the masses when it demonstrates ad hominem, and it demonstrates ad hominem, when it becomes radical. To be radical is to grasp things by the root, but for man the root is man himself. The clear proof of the radicalism of German theory, and hence of its political energy, is that it proceeds from the decisive positive abolition of religion.

It is the slowest pulsation which is the most vital. The hero will then know how to wait, as well as to make haste. All good abides with him who waiteth wisely.

He has spent all his life in letting down empty buckets into empty wells; and he is frittering away his age in trying to draw them up again.

Such souls are, in these days, getting somewhat out of humour with the world. Your very Byron, in these days, is at least driven mad; flatly refuses fealty to the world. The world with its injustices, its golden brutalities, and dull yellow guineas, is a disgust to such souls: the ray of Heaven that is in them does at least pre-doom them to be very miserable here. Yes:-and yet all misery is faculty misdirected, strength that has not yet found its way. The black whirlwind is mother of the lightning. No smoke, in any sense, but can become flame and radiance! Such soul, once graduated in Heaven's stern University, steps out superior to your guinea.

The Methods of Observation of Quantity in general, are 'Numeration', which is precise by the nature of Number; the 'Measurement of Space' and 'of Time', which are easily made precise; the 'Conversion of Space and Time', by which each aids the measurement of the other. The Idea of Space becomes more clear by studying 'Geometry'; the Idea of Force, by studying 'Mechanics'; the Ideas of Likeness, of Kind, of subordination of Classes, by studying 'Natural History'.

Both of us victims of the same twentieth-century plague. Not the Black Death, this time; the Grey Life.

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?

All savageness is a sign of weakness.

The ethical and political practice of nonviolence can rely neither exclusively on the dyadic encounter, nor on the bolstering of a prohibition; it requires a political opposition to the biopolitical forms of racism and war logics that rely on phantasmagoric inversions that occlude the binding and interdependent character of the social bond. It requires, as well, an account of why, and under what conditions, the frameworks for understanding violence and nonviolence, or violence and self-defense, seem to invert into one another, causing confusion about how best to pin down those terms.

Bad times have a scientific value. [...] We learn geology the morning after the earthquake, on ghastly diagrams of cloven mountains, upheaved plains, and the dry bed of the sea.

The principal aim of mathematical education is to develop certain faculties of the mind, and among these intuition is not the least precious. It is through it that the mathematical world remains in touch with the real world, and even if pure mathematics could do without it, we should still have to have recourse to it to fill up the gulf that separates the symbol from reality.

I should have loved freedom, I believe, at all times, but in the time in which we live I am ready to worship it.

Let us not underrate the value of a fact; it will one day flower in a truth.

Immortality. I notice that as soon as writers broach this question they begin to quote. I hate quotation. Tell me what you know.

The tiger that assails me is in the right, and I who strike him down am also in the right. I defend against him not my right, but myself.

Reorganisation, irrespectively of God or king, by the worship of Humanity, systematically adopted. Man's only right is to do his duty. The Intellect should always be the servant of the Heart, and should never be its slave.

There will be a time when those trying to turn the world into a Colosseum for their own amusement will be raw meat thrown to the wolves themselves, and the rest of us will watch, as justice is served, with a clean conscience.

I too am not one to despise myths, and I am far from rejecting those that have the right tendency; indeed I am of the same opinion as you and your admired, or rather the universally admired, Plato. He also often conveyed a serious lesson in his myths.

She [virtue] requires a rough and stormy passage; she will have either outward difficulties to wrestle with, ... or internal difficulties.

Freedom is the alone unoriginated birthright of man, and belongs to him by force of his humanity; and is independence on the will and co-action of every other in so far as this consists with every other person's freedom.

What all agree upon is probably right; what no two agree in most probably is wrong.

So that it will be found that the fundamental fault in the character of women is that they have no "sense of justice ." This arises from their deficiency in the power of reasoning already referred to, and reflection, but is also partly due to the fact that Nature has not destined them, as the weaker sex, to be dependent on strength but on cunning; this is why they are instinctively crafty, and have an ineradicable tendency to lie.

The Left's identity politics poses a threat to free speech and to the kind of rational discourse needed to sustain a democracy... The focus on lived experience by identity groups prioritizes the emotional world of the inner self over the rational examination of issues in the outside world and privileges sincerely held opinions over a process of reasoned deliberation that may force one to abandon prior opinions.

Ours is a problem in which deception has become organized and strong; where truth is poisoned at its source; one in which the skill of the shrewdest brains is devoted to misleading a bewildered people.

The necessity for power is obvious, because life cannot be lived without order; but the allocation of power is arbitrary because all men are alike, or very nearly. Yet power must not seem to be arbitrarily allocated, because it will not then be recognized as power. Therefore prestige, which is illusion, is of the very essence of power.

Why is it after a century of socialist disasters, and an intellectual legacy that has been time and again exploded, the left-wing position remains, as it were, the default position to which thinking people gravitate when called upon for a comprehensive philosophy? Why are "right-wingers" marginalised in the educational system, denounced in the media and regarded by our political class as untouchable, fit only to clean up after the orgies of luxurious nonsense indulged in by their moral superiors?

Of things that are external, happen what will to that which can suffer by external accidents. Those things that suffer let them complain themselves, if they will; as for me, as long as I conceive no such thing, that that which is happened is evil, I have no hurt; and it is in my power not to conceive any such thing.

Ideas, cultures, and histories cannot seriously be understood or studied without their force, or more precisely their configurations of power, also being studied.

Those that will combat use and custom by the strict rules of grammar do but jest.

The Sophist demonstrates that everything is true and nothing is true.

We are not so absurd as to propose that the teacher should not set forth his own opinions as the true ones and exert his utmost powers to exhibit their truth in the strongest light. To abstain from this would be to nourish the worst intellectual habit of all, that of not finding, and not looking for, certainty in any teacher. But the teacher himself should not be held to any creed; nor should the question be whether his own opinions are the true ones, but whether he is well instructed in those of other people, and, in enforcing his own, states the arguments for all conflicting opinions fairly.

Man ought to be content, it is said; but with what?
