Most men and women, by birth or nature, lack the means to advance in wealth and power, but all have the ability to advance in knowledge.

So monstrous is the making and keeping them slaves at all, abstracted from the barbarous usage they suffer, and the many evils attending the practice; as selling husbands away from wives, children from parents, and from each other, in violation of sacred and natural ties; and opening the way for adulteries, incests, and many shocking consequences, for all of which the guilty Masters must answer to the final Judge.

History is a bath of blood.

Experience has repeatedly confirmed that well-known maxim of Bacon's that "a little philosophy inclineth a man's mind to atheism, but depth in philosophy bringeth men's minds about to religion." At the same time, when Bacon penned that sage epigram... he forgot to add that the God to whom depth in philosophy brings back men's minds is far from being the same from whom a little philosophy estranges them.

The most profound joy has more of gravity than of gaiety in it.

I assert(1) There is no method of discovering a scientific theory.(2) There is no method of ascertaining the truth [i.e., verification] of a scientific hypothesis...(3) There is no method of ascertaining whether a hypothesis is 'probable', in the sense of the probability calculus.

Covetousness, and the desire of having in our possession, and under our dominion, more than we have need of, being the root of all evil, should be early and carefully weeded out, and the contrary quality of a readiness to impart to others, implanted. This should be encourag'd by great commendation and credit, and constantly taking care that he loses nothing by his liberality.

Do not be guilty of possessing a library of learned books while lacking learning yourself.

One may discover the root of a Hindoo religion in his own private history, when, in the silent intervals of the day or night, he does sometimes inflict on himself like austerities with a stern satisfaction.

Those who compare the age in which their lot has fallen with a golden age which exists only in imagination, may talk of degeneracy and decay; but no man who is correctly informed as to the past, will be disposed to take a morose or desponding view of the present.

Agesilaus was very fond of his children; and it is reported that once toying with them he got astride upon a reed as upon a horse, and rode about the room; and being seen by one of his friends, he desired him not to speak of it till he had children of his own.

I think he once told us his first short clothes were a hull made mostly or wholly of leather. We all only laughed, for it is now long ago. Thou dear father! Through what stern obstructions was thy way to manhood to be forced, and for us and for our travelling to be made smooth!

In speaking of sociological laws or natural laws of social life I have in mind such laws as are formulated by modern economic theories, for instance, the theory of international trade, or the theory of the trade cycle. These and other important sociological laws are connected with the functioning of social institutions. These laws play a role in our social life corresponding to the role played in mechanical engineering by, say, the principle of the lever. For institutions, like levers, are needed if we want to achieve anything which goes beyond the power of our muscles. Like machines, institutions multiply our power for good or evil. Like machines, they need intelligent supervision by someone who understands their way of functioning and, most of all, their purpose, since we cannot build them so that they work entirely automatically.

What most clearly characterizes true freedom and its true employment is its misemployment.

The evil that has resulted from the error of the schools in teaching natural philosophy as an accomplishment only has been that of generating in the pupils a species of atheism. Instead of looking through the works of creation to the Creator Himself, they stop short and employ the knowledge they acquire to create doubts of His existence. They labor with studied ingenuity to ascribe everything they behold to innate properties of matter and jump over all the rest by saying that matter is eternal.

It is manifest that every soul has a certain continuity with the soul of the Universe, so that it must be understood to exist and to be included not only there where it liveth and feeleth, but it is also by its essence and substance diffused throughout immensity. The power of each soul is itself somehow present afar in the Universe. It is not mixed, yet is there in some presence.

There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. The first kind have had thoughts or experiences which seem to them worth communicating, while the second kind need money and consequently write for money.

Not much younger than these (sc. Hermotimus of Colophon and Philippus of Mende) is Euclid, who put together the Elements, collecting many of Eudoxus' theorems, perfecting many of Theaetetus', and also bringing to irrefragable demonstration the things which were only somewhat loosely proved by his predecessors. This man lived in the time of the first Ptolemy. For Archimedes, who came immediately after the first (Ptolemy), makes mention of Euclid: and, further, they say that Ptolemy once asked him if there was in geometry any shorter way than that of the elements, and he answered that there was no royal road to geometry. He is then younger than pupils of Plato but older than Eratosthenes and Archimedes; for the latter were contemporary with one another, as Eratosthenes somewhere says.

If people were told: what makes carnal desire imperious in you is not its pure carnal element. It is the fact that you put into it the essential part of yourself-the need for Unity, the need for God - they wouldn't believe it. To them it seems obvious that the quality of imperious need belongs to the carnal desire as such. In the same way it seems obvious to the miser that the quality of desirability belongs to gold as such, and not to its exchange value.

The natural way of doing this [seeking scientific knowledge or explanation of fact] is to start from the things which are more knowable and obvious to us and proceed towards those which are clearer and more knowable by nature; for the same things are not 'knowable relatively to us' and 'knowable' without qualification. So in the present inquiry we must follow this method and advance from what is more obscure by nature, but clearer to us, towards what is more clear and more knowable by nature. Now what is to us plain and obvious at first is rather confused masses, the elements and principles of which became known to us by later analysis...

As to fidelity, there is no animal in the world so treacherous as man. Our histories have recorded the violent pursuits that dogs have made after the murderers of their masters.

The man who comes back through the Door in the Wall will never be quite the same as the man who went out. He will be wiser but less cocksure, happier but less self-satisfied, humbler in acknowledging his ignorance yet better equipped to understand the relationship of words to things, of systematic reasoning to the unfathomable Mystery which it tries, forever vainly, to comprehend.

Force overcome by force.

Good breeding in cattle depends on physical health, but in men on a well-formed character.

As man is so constituted that it is utterly impossible for him to attain happiness save by seeking the happiness of others, so does it seem to be of the nature of things that individuals and classes can obtain their own just rights only by struggling for the rights of others.

In thinking of history in this [progressive & eschatological] way Islam shares common ground with Christianity and with the secular creeds of the modern West. It is misleading to represent Islam and 'the West' as forming civilisations that have nothing in common. Christianity and Islam are integral parts of western monotheism, and as such they share a view of history that marks them off from the rest of the world. Both are militant faiths that seek to convert all humankind. Other religions have been implicated in twentieth-century violence-the state cult of Shintō in Japan during the militarist period and Hindu nationalism in contemporary India, for example. But only Christianity and Islam have engendered movements that are committed to the systematic use of force to achieve universal goals.

The general interest of the masses might take the place of the insight of genius if it were allowed freedom of action.

If you well apprehend and keep in mind these things, nature free at once and rid of her haughty lords is seen to do all things spontaneously of herself without the meddling of the gods.

This heart within me I can feel, and I judge that it exists. This world I can touch, and I likewise judge that it exists. There ends all my knowledge, and the rest is construction. For if I try to seize this self of which I feel sure, if I try to define and to summarize it, it is nothing but water slipping through my fingers. I can sketch one by one all the aspects it is able to assume, all those likewise that have been attributed to it, this upbringing, this origin, this ardor or these silences, this nobility or this vileness. But aspects cannot be added up. This very heart which is mine will forever remain indefinable to me. Between the certainty I have of my existence and the content I try to give to that assurance, the gap will never be filled. Forever I shall be a stranger to myself.

Tis certainly a kind of indignity to philosophy, whose sovereign authority ought every where to be acknowledg'd, to oblige her on every occasion to make apologies for her conclusions, and justify herself to every particular art and science, which may be offended at her.

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

To counter the fixation on a rhetoric of victimhood, black folks must engage in a discourse of self-determination.

Much can be inferred about a man from his mistress: in her one beholds his weaknesses and his dreams.

There is hardly a member of Congress who can make up his mind to go home without having despatched at least one speech to his constituents; nor who will endure any interruption until he has introduced into his harangue whatever useful suggestions may be made touching the four-and-twenty States of which the Union is composed, and especially the district which he represents.

Man is an enigma whose knot has not ceased to occupy observers. The contradictions that he contains astonish reason and impose silence on it. So what is this inconceivable being who carries within him powers that clash and who is obliged to hate himself in order to esteem himself?

Ideas are cheap. It's only what you do with them that counts.

Remind yourself that all men assert that wisdom is the greatest good, but that there are few who strenuously seek out that greatest good.

I am a weak, ephemeral creature made of mud and dream. But I feel all the powers of the universe whirling within me.

It is impossible that each of the elements should be infinite. For that is body which has interval on all sides; and that is infinite which has extension without bound.

There is nothing wrong with meditating just to meditate, in the same way that you listen to music just for the music. If you go to concerts to "get culture" or to improve your mind, you will sit there as deaf as a doorpost.

There is a connected set of events (light-waves) travelling outward from a centre... there are some respects in which all events are alike, and others in which they differ... We must not think of a light-wave as a 'thing', but as a connected group of rhythmical events. The mathematical characteristics of such a group can be inferred by physics, but the intrinsic character of the component events cannot be inferred.

The debates of that great assembly are frequently vague and perplexed, seeming to be dragged rather than to march, to the intended goal. Something of this sort must, I think, always happen in public democratic assemblies.

Men are not allowed to think freely about chemistry and biology: why should they be allowed to think freely about political philosophy?

Think not disdainfully of death, but look on it with favor; for even death is one of the things that Nature wills.

Supreme power rests in the will of all or of the majority.

By now it may be clear that the position I'm developing is a sort of post-Darwinian Kantianism.
