How can a rational being be ennobled by anything that is not obtained by its own exertions?

Since I have spread my wings to purpose high, The more beneath my feet the clouds I see, The more I give the winds my pinions free, Spurning the earth and soaring to the sky.

We must consider both the ultimate end and all clear sensory evidence, to which we refer our opinions; for otherwise everything will be full of uncertainty and confusion.

I define a Sign as anything which is so determined by something else, called its Object, and so determines an effect upon a person, which effect I call its Interpretant, that the latter is thereby mediately determined by the former.

It is difficult, if not impossible, to define the limit of our reasonable desires in respect of possessions.

Suppose Odin to have been the inventor of Letters, as well as "magic," among that people! It is the greatest invention man has ever made! this of marking down the unseen thought that is in him by written characters. It is a kind of second speech, almost as miraculous as the first.

A book is a mirror: if an ape looks into it an apostle is hardly likely to look out. We have no words for speaking of wisdom to the stupid. He who understands the wise is wise already.

Fortune has taken away, but Fortune has given.

Just as it sometimes happens that deformed offspring are produced by deformed parents, and sometimes not, so the offspring produced by a female are sometimes female, sometimes not, but male, because the female is as it were a deformed male.

The strangest, most generous, and proudest of all virtues is true courage.

The soul is the prison of the body.

At one level, this movement on behalf of oppressed farm animals is emotional...Yet the movement is also the product of a deep intellectual ferment pioneered by the Princeton scholar Peter Singer...This idea popularized by Professor Singer - that we have ethical obligations that transcend our species - is one whose time appears to have come...What we're seeing now is an interesting moral moment: a grass-roots effort by members of one species to promote the welfare of others...animal rights are now firmly on the mainstream ethical agenda.

The space of early Greek cosmology was structured by logos - resonant utterance or word.

You see that man can endure toil: Cato, on foot, led an army through African deserts. You see that thirst can be endured: he marched over sun-baked hills, dragging the remains of a beaten army and with no train of supplies, undergoing lack of water and wearing a heavy suit of armour; always the last to drink of the few springs which they chanced to find. You see that honour, and dishonour too, can be despised: for they report that on the very day when Cato was defeated at the elections, he played a game of ball. You see also that man can be free from fear of those above him in rank: for Cato attacked Caesar and Pompey simultaneously, at a time when none dared fall foul of the one without endeavouring to oblige the other. You see that death can be scorned as well as exile: Cato inflicted exile upon himself and finally death, and war all the while.

Everyone has a religion, whether admitted or not, because it is impossible to be human without having some basic assumptions (or intuitions) about existence and the good life.

Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

For remember that in general we don't use language according to strict rules - it hasn't been taught us by means of strict rules, either.

Is it not a noble farce, wherein kings, republics, and emperors have for so many ages played their parts, and to which the whole vast universe serves for a theatre?

It appears then, that capitalist production comprises conditions independent of good or bad will, conditions which permit the working-class to enjoy that relative prosperity only momentarily, and at that always only as the harbinger of a coming crisis.

The abolition of the market means not only that the consumers-that is all members of society-are robbed of virtually all choice of consumption and all influence over production; it also means that the information and communication are monopolized by the State, as they too need a vast material base in order to operate. The abolition of the market means, then, that both material and intellectual assets would be totally rationed. To say nothing of the inefficiency of production convincingly demonstrated in the history of communism, this economy requires an omnipotent police state. Briefly: the abolition of the market means a gulag society.

But there is a devil of a difference between barbarians who are fit by nature to be used for anything, and civilized people who apply them selves to everything.

With the exception of professional rationalists, today people despair of true knowledge. If the only significant history of human thought were to be written, it would have to be history of its successive regrets and impotences.

If Governments neglect to invite what noble intellect there is, then too surely all intellect, not omnipotent to resist bad influences, will tend to become beaverish ignoble intellect; and quitting high aims, which seem shut up from it, will help itself forward in the way of making money and such like; or will even sink to be sham intellect, helping itself by methods which are not only beaverish but vulpine, and so "ignoble" as not to have common honesty.

"The Precession of Simulacra,"

My life has been full of terrible misfortunes most of which never happened.

Christianity possesses the great advantage over Judaism of being represented as coming from the mouth of the first Teacher not as a statutory but as a moral religion, and as thus entering into the closest relation with reason so that, through reason, it was able of itself, without historical learning, to be spread at all times and among all peoples with the greatest trustworthiness.

All characteristics of material things as they are presented to us in the acts of external perception (e.g. colour) are endowed with the separateness of spatial extension, but it is only when we build up a single connected real world out of all our experiences that the spatial extension, which is a constituent of every perception, becomes a part of one and the same all-inclusive space. ... every material thing can, without changing content, equally well occupy a position in Space different from its present one. This immediately gives us the property of the homogeneity of space which is the root of the conception, Congruence.

One might call habit a moral friction: something that prevents the mind from gliding over things but connects it with them and makes it hard for it to free itself from them.

The art of being wise is the art of knowing what to overlook.

Why trouble ye the woman? for she hath wrought a good work upon me. For ye have the poor always with you; but me ye have not always. For in that she hath poured this ointment on my body, she did it for my burial. Verily I say unto you, Wheresoever this gospel shall be preached in the whole world, there shall also this, that this woman hath done, be told for a memorial of her.

As much in vain, perhaps, will they search ancient history for examples of the modern Slave-Trade. Too many nations enslaved the prisoners they took in war. But to go to nations with whom there is no war, who have no way provoked, without farther design of conquest, purely to catch inoffensive people, like wild beasts, for slaves, is an hight of outrage against Humanity and Justice, that seems left by Heathen nations to be practised by pretended Christians. How shameful are all attempts to colour and excuse it!

I have in this treatise followed the mathematical method, if not with all strictness, at least imitatively, not in order, by a display of profundity, to procure a better reception for it, but because I believe such a system to be quite capable of it, and that perfection may in time be obtained by a cleverer hand, if stimulated by this sketch, mathematical investigators of nature should find it not unimportant to treat the metaphysical portion, which anyway cannot be got rid of, as a special fundamental department of general physics, and to bring it into unison with the mathematical doctrine of motion.

Every poet has trembled on the verge of science.

The possibility of democracy on a global scale is emerging today for the very first time.

With competition is connected less the intention to do the thing best than the intention to make it as profitable, as productive, as possible. Hence people study to get into the civil service (study in order to get a well-paid job), study cringing and flattery, routine and 'acquaintance with business', work 'for appearance'. Hence, while it is apparently a matter of doing 'good service', in truth only a 'good business' and earning of money are looked out for. The job is done only ostensibly for the job's sake, but in fact on account of the gain that it yields. One would indeed prefer not to be censor, but one wants to be - advanced; one would like to judge, administer, etc., according to his best convictions, but one is afraid of transfer or even dismissal; one must, above all things - live.

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.

Make thyself pure, 0 righteous man! Anyone in the world here below can win purity for himself, namely, when he cleanses himself with Good Thoughts, Good Words, and Good Deeds.

What is it that distinguishes man from animals? It is not his upright posture. That was present in the apes long before the brain began to develop. Nor is it the use of tools. It is something altogether new, a previously unknown quality: self-awareness. Animals, too, have awareness. They are aware of objects; they know this is one thing and that another. But when the human being as such was born he had a new and different consciousness, a consciousness of himself; he knew that he existed and that he was something different, something apart from nature, apart from other people, too. He experienced himself. He was aware that he thought and felt. As far as we know, there is nothing analogous to this anywhere in the animal kingdom. That is the specific quality that makes human beings human.

The law of the table is beauty, a respect to the common soul of the guests. Everything is unreasonable which is private to two or three, or any portion of the company. Tact never violates for a moment this law; never intrudes the orders of the house, the vices of the absent, or a tariff of expenses, or professional privacies; as we say, we never "talk shop" before company. Lovers abstain from caresses, and haters from insults, while they sit in one parlor with common friends.

The friendship of one wise man is better than the friendship of a host of fools.

Let us read, and let us dance; these two amusements will never do any harm to the world.

Parents will strip themselves of everything, will sacrifice everything for the physical well-being of their child, will wake nights and stand in fear and agony before some physical ailment of their beloved one; but will remain cold and indifferent, without the slightest understanding before the soul cravings and the yearnings of their child, neither hearing nor wishing to hear the loud knocking of the young spirit that demands recognition. On the contrary, they will stifle the beautiful voice of spring, of a new life of beauty and splendor of love; they will put the long lean finger of authority upon the tender throat and not allow vent to the silvery song of the individual growth, of the beauty of character, of the strength of love and human relation, which alone make life worth living.

Even more than in a poem, it is the aphorism that the word is god.

Philosophy may in no way interfere with the actual use of language; it can in the end only describe it.

That's... the crisis. The number of liberal democracies measured by... Freedom House in its annual survey of freedom around the world has been in decline for 16 straight years, and the biggest declines recently have been in the two biggest liberal democracies, India and the United States. So... we're dealing with a big global problem.

Those who have been once intoxicated with power, and have derived any kind of emolument from it, even though but for one year, never can willingly abandon it. They may be distressed in the midst of all their power; but they will never look to any thing but power for their relief.

There is geometry in the humming of the strings, there is music in the spacing of the spheres.

We can not... escape the conclusion that the rule of reasoning by recurrence is irreducible to the principle of contradiction. ...Neither can this rule come to us from experience... This rule, inaccessible to analytic demonstration and to experience, is the veritable type of the synthetic a priori judgment. On the other hand, we can not think of seeing in it a convention, as in some of the postulates of geometry. ...it is only the affirmation of the power of the mind which knows itself capable of conceiving the indefinite repetition of the same act when once this act is possible. The mind has a direct intuition of this power, and experience can only give occasion for using it and thereby becoming conscious of it.
