For man to become successful, for man to establish himself as the ruler of the planet, it was necessary for him to use his brain as something more than a device to make the daily routine of getting food and evading enemies a little more efficient. Man had to learn to control his environment.

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

In spite the mountains of books written about art, no precise definition of art has been constructed. And the reason for this is that the conception of art has been based on the conception of beauty.

All truth, in the long run, is only common sense clarified.

The heavens are as deep as our aspirations are high.

By Thy perfect Intelligence, O MazdaThou didst first create us having bodies and spiritual consciences,And by Thy Thought gave our selves the power of thought, word, and deed.Thus leaving us free to choose our faith at our own will.

Most kings and priests have been despotic, and all religions have been riddled with superstition.

As soon as one returns to Doubt (if it could be said that one has ever left it), undertaking anything at all seems not so much useless as extravagant. Doubt works deep within you like a disease, or even more effectively, like a faith.

The ultimate result of shielding men from the effects of folly, is to fill the world with fools.

The doctrine of Right and Wrong, is perpetually disputed, both by Pen and the Sword: Whereas the doctrine of Lines, and Figures, is not so; because men care not, in that subject what be truth, as a thing that crosses no mans ambition, profit, or lust. For I doubt not, but if it had been a thing contrary to any mans right of dominion, or to the interest of men that have dominion, That the three Angles of a Triangle, should be equall to two Angles of a Square; that doctrine should have been, if not disputed, yet by the burning of all books of Geometry, suppressed, as far as he whom it concerned was able.

A culture is in its finest flower before it begins to analyze itself.

It seems as if the female spirit of the world were mourning everlastingly over blessings, not lost, but which she has never had, and which, in her discouragement she feels that she never will have, they are so far off.

Democratic socialists are either proletarians who are not yet sufficiently clear about the conditions of the liberation of their class, or they are representatives of the petty bourgeoisie, a class which, prior to the achievement of democracy and the socialist measures to which it gives rise, has many interests in common with the proletariat. It follows that, in moments of action, the communists will have to come to an understanding with these democratic socialists, and in general to follow as far as possible a common policy with them - provided that these socialists do not enter into the service of the ruling bourgeoisie and attack the communists. It is clear that this form of co-operation in action does not exclude the discussion of differences.

It would be better to be without the Shu-King than to believe every word of it.

Time is the wisest of all things that are; for it brings everything to light.

There is a great difference between the Idols of the human mind and the Ideas of the divine. That is to say, between certain empty dogmas, and the true signatures and marks set upon the works of creation as they are found in nature.

If we cannot "practice the presence of God," it is something to practice the absence of God, to become increasingly aware of our unawareness till we feel like man who should stand beside a great cataract and hear no noise, or like a man in a story who looks in a mirror and finds no face there, or a man in a dream who stretches his hand to visible objects and gets no sensation of touch. To know that one is dreaming is to no longer be perfectly asleep. Bur for news of the fully waking world you must go to my betters.

Perhaps I am more than usually jealous with respect to my freedom. I feel that my connection with and obligation to society are still very slight and transient. Those slight labors which afford me a livelihood, and by which it is allowed that I am to some extent serviceable to my contemporaries, are as yet commonly a pleasure to me, and I am not often reminded that they are a necessity. So far I am successful. But I foresee, that, if my wants should be much increased, the labor required to supply them would become a drudgery. If I should sell both my forenoons and afternoons to society, as most appear to do, I am sure, that, for me, there would be nothing left worth living for. I trust that I shall never thus sell my birthright for a mess of pottage.

Love, a tacit agreement between two unhappy parties to overestimate each other. p. 111, first American edition

Let him sensibly perceive, that the kindness he shews to others, is no ill husbandry for himself; but that it brings a return in kindness both from those that receive it, and those who look on. Make this a contest among children, who shall out-do one another in this way: and by this means, by a constant practise, children having made it easy to themselves to part with what they have, good nature may be settled in them into a habit, and they may take pleasure, and pique themselves in being kind, liberal and civil, to others.

But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

In its mad passion for power, the Communist State even sought to strengthen and deepen the very ideas and conceptions which the Revolution had come to destroy. It supported and encouraged all the worst antisocial qualities and systematically destroyed the already awakened conception of the new revolutionary values.The sense of justice and equality, the love of liberty and of human brotherhood - these fundamentals of the real regeneration of society - the Communist State suppressed to the point of extermination. Man's instinctive sense of equity was branded as weak sentimentality; human dignity and liberty became a bourgeois superstition; the sanctity of life, which is the very essence of social reconstruction, was condemned as unrevolutionary, almost counter-revolutionary. This fearful perversion of fundamental values bore within itself the seed of destruction.

Fortune is lavish with her favors, but not to be depended on. Nature on the other hand is self-sufficing, and therefore with her feebler but trustworthy [resources] she wins the greater [meed] of hope.

We are organization watchers in our role as citizens. Increasing attention has been fixed in recent years upon the functioning of society's organizations: its large corporations and its governments. Hence this could also be described as a book for Everyman-for it proposes a way of thinking about organizational issues that concern us all.

Rational mechanics must be the science of the motions which result from any forces, and of the forces which are required for any motions, accurately propounded and demonstrated. For many things induce me to suspect, that all natural phenomena may depend upon some forces by which the particles of bodies are either drawn towards each other, and cohere, or repel and recede from each other: and these forces being hitherto unknown, philosophers have pursued their researches in vain. And I hope that the principles expounded in this work will afford some light, either to this mode of philosophizing, or to some mode which is more true.

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

From a correct Marxian point of view ... all measures designed to restrain, to regulate and to improve capitalism were simply "petty-bourgeois" nonsense ... True socialists should not place any obstacles in the way of capitalist evolution. For only the full maturity of capitalism could bring about socialism. It is not only vain, but harmful to the interests of the proletarians to resort to such measures.

It is a bad thing to perform menial duties even for the sake of freedom; to fight with pinpricks, instead of with clubs. I have become tired of hypocrisy, stupidity, gross arbitrariness, and of our bowing and scraping, dodging, and hair-splitting over words. Consequently, the government has given me back my freedom.

You don't have a soul. You are a soul. You have a body.

The brain may be regarded as a kind of parasite of the organism, a pensioner, as it were, who dwells with the body.

The Philosophy of Nature takes up the material, prepared for it by physics out of experience, at the point to which physics has brought it, and again transforms it, without basing it ultimately on the authority of experience. Physics therefore must work into the hands of philosophy, so that the latter may translate into a true comprehension (Begriff) the abstract universal transmitted to it, showing how it issues from that comprehension as an intrinsically necessary whole.

Mahomet established a religion by putting his enemies to death; Jesus Christ, by commanding his followers to lay down their own lives.

Humanists today, who claim to take a wholly secular view of things, scoff at mysticism and religion. But the unique status of humans is hard to defend, and even to understand, when it is cut off from any idea of transcendence. In a strictly naturalistic view - one in which the world is taken on its own terms, without reference to a creator or any spiritual realm - there is no hierarchy of value with humans at the top. There are simply multifarious animals, each with their own needs. Human uniqueness is a myth inherited from religion, which humanists have recycled into science.

There is no idea so obscure that someone could not come to regard it as self-evident.

Men will not understand ... that when they fulfil their duties to men, they fulfil thereby God's commandments; that they are consequently always in the service of God, as long as their actions are moral, and that it is absolutely impossible to serve God otherwise.

They are splendidly built [Italian Hospitals], the best food and drink are at hand, the attendants are very diligent, the physicians are learned, the beds and coverings are very clean, and the bedsteads are painted. As soon as a sick man is brought in, all his clothes are taken off in the presence of a notary and are faithfully kept for him. He is then laid in a handsomely painted bed with clean sheets. Two physicians are fetched at once. Attendants come with food and drink, served in immaculate glass vessels; these are not touched with as much as a finger but are brought on a tray.

It is a most earnest thing to be alive in this world; to die is not sport for a man. Man's life never was a sport to him; it was a stern reality, altogether a serious matter to be alive!

When I was a child, the institution of war, which, by then, had been in existence for perhaps about five thousand years, was still being taken for granted by most people in the World as a normal and acceptable fact of life. One small religious community, the Society of Friends, was at that time singular in condemning war as immoral and in consequently refusing to have any part or lot in war-making.

I will not talk about people a thousand miles off, but come as near home as I can. As the time is short, I will leave out all the flattery, and retain all the criticism. Let us consider the way in which we spend our lives.

Now, to say that a lot of objects is finite, is the same as to say that if we pass through the class from one to another we shall necessarily come round to one of those individuals already passed; that is, if every one of the lot is in any one-to-one relation to one of the lot, then to every one of the lot some one is in this same relation.

If anything extraordinary seems to have happened, we can always say that we have been the victims of an illusion. If we hold a philosophy which excludes the supernatural, this is what we always shall say.

So far from the posterior lobe, the posterior cornu, and the hippocampus minor, being structures peculiar to and characteristic of man, as they have been over and over again asserted to be, even after the publication of the clearest demonstration of the reverse, it is precisely these structures which are the most marked cerebral characters common to man with the apes. They are among the most distinctly Simian peculiarities which the human organism exhibits.

If the press was to be free, nothing would be so important as precisely its liberation from every coercion that could be put on it in the name of a law. And, that it might come to that, I my own self should have to have absolved myself from obedience to the law.

Of what I am, I know no more than that I am, but here no tie is necessary between subject and object. My own being is this tie, I am at once the subject knowing, and the object known of; and this reflection or return of the knowledge on itself is what I designate by the term I, if I have any determinate meaning.

By nature a philosopher is not in genius and disposition half so different from a street porter, as a mastiff is from a greyhound.

Nothing is lost, nothing wholly passes away, for in some way or another everything is perpetuated; and everything, after passing through time, returns to eternity.

No man of sense can put himself and his soul under the control of names... You must consider courageously and thoroughly and not accept anything carelessly.

When things fall out opportunely for the person concerned, he is not apt to be critical about the how or why, his own immediate personal convenience seeming a sufficient reason for the strangest oddities and revolutions in our sublunary things.
