Eternal vigilance is the price of knowledge.

In the general tendency toward specialization, philosophy too has established itself as a specialized discipline, one purified of all specific content. In so doing, philosophy has denied its own constitutive concept: the intellectual freedom that does not obey the dictates of specialized knowledge.

We cannot grasp any idea, any organ of meditation, we cannot possess it in full force, until we have felt and sensed it, as much so as if it were an odor or a color.

A house may be large or small; as long as the neighboring houses are likewise small, it satisfies all social requirement for a residence. But let there arise next to the little house a palace, and the little house shrinks to a hut. The little house now makes it clear that its inmate has no social position at all to maintain, or but a very insignificant one; and however high it may shoot up in the course of civilization, if the neighboring palace rises in equal or even in greater measure, the occupant of the relatively little house will always find himself more uncomfortable, more dissatisfied, more cramped within his four walls.

We always love . . . despite; and that "despite" covers an infinity.

The potential of any new technology is always dissipated by its users involvement in its predecessors.

And of universal nature, the notion I would offer, should be something like this. Nature is the aggregate of the bodies, that make up the world, in its present state, considered as a principle, by virtue whereof, they act and suffer, according to the laws of motion, prescribed by the author of things.

Every parting gives a foretaste of death, every reunion a hint of the resurrection.

He knows his own strength; he knows that he was born to carry burdens.

In a valiant suffering for others, not in a slothful making others suffer for us, did nobleness ever lie.

Continuously thou wilt look at human things as smoke and nothing at all; especially if thou reflectest at the same time, that what has once changed will never exist again in the infinite duration of time. But thou, in what a brief space of time is thy existence? And why art thou not content to pass through this short time in an orderly way?

Compassion is the desire that moves the individual self to widen the scope of its self-concern to embrace the whole of the universal self.

There is no passion so contagious as that of fear.

Wealth is like sea-water; the more we drink, the thirstier we become.

Why tempt ye me, ye hypocrites? Shew me the tribute money.

By phonemic transformation into visual terms, the alphabet became a universal, abstract, static container of meaningless sounds.

The bourgeoisie has stripped of its halo every occupation hitherto honoured and looked up to with reverent awe. It has converted the physician, the lawyer, the priest, the poet, the man of science, into its paid wage labourers.

To say that the activity of science and art helps humanity's progress, if by that activity we mean the activity which now calls itself by those names, is as though one said that the clumsy, obstructive splashing of oars in a boat moving down stream assists the boat's progress. It only hinders it... The proof of this is seen in the confession made by men of science that the achievements of the arts and sciences are inaccessible to the labouring masses on account of the unequal distribution of wealth.

... a penny saved is better than a penny earned.

When you are reading God's Word, it is not the obscure passages that bind you but what you understand, and with that you comply at once. If you understood only one single passage in all of Holy Scripture, well, then you must do that first of all, but you do not first have to sit down and ponder the obscure passages.

When I started life Hegelianism was the basis of everything: it was in the air, found expression in magazine and newspaper articles, in novels and essays, in art, in histories, in sermons, and in conversation. A man unacquainted with Hegel had no right to speak: he who wished to know the truth studied Hegel. Everything rested on him; and suddenly forty years have gone by and there is nothing left of him, he is not even mentioned - as though he had never existed. And what is most remarkable is that, like pseudo-Christianity, Hegelianism fell not because anyone refuted it, but because it suddenly became evident that neither the one nor the other was needed by our learned, educated world.

The second requirement of a virus-friendly environment - that it should obey a program of coded instructions - is again only quantitatively less true for brains than for cells or computers. We sometimes obey orders from one another, but also we sometimes don't. Nevertheless, it is a telling fact that, the world over, the vast majority of children follow the religion of their parents rather than any of the other available religions. Instructions to genuflect, to bow towards Mecca, to nod one's head rhythmically towards the wall, to shake like a maniac, to "speak in tongues" - the list of such arbitrary and pointless motor patterns offered by religion alone is extensive - are obeyed, if not slavishly, at least with some reasonably high statistical probability.

But with respect to future debt; would it not be wise and just for that nation to declare in the constitution they are forming that neither the legislature, nor the nation itself can validly contract more debt, than they may pay within their own age, or within the term of 19 years.

We have seen that language is something precious because it allows us to express ourselves; but it is fatal when one allows oneself to be completely led astray by it, because then it prevents one from expressing oneself. Language is the source of the prejudices and haste which Descartes thought of as the sources of error.

In closing, I can only apologize for not having given any positive account of either mathematical truth or mathematical necessity. I can only say that I have not given such an account because I think that the search for such an account is a fundamental mistake. It is not that there is nothing special about mathematics; it is that, in my opinion, the investigation of mathematics must presuppose and not seek to account for the truth of mathematics. But this is the beginning of another paper and not the end of this one.

Man's power appears to have increased out of all proportion to his wisdom. He has never been in a better position to build a healthy, happy, and productive world; yet things have perhaps never seemed so black.

Days of absence,

sad and dreary, 

Clothed in sorrow's dark array,

Days of absence, I am weary: She I love is far away.

The great majority of men and women, in ordinary times, pass through life without ever contemplating or criticising, as a whole, either their own conditions or those of the world at large. They find themselves born into a certain place in society, and they accept what each day brings forth, without any effort of thought beyond what the immediate present requires. Almost as instinctively as the beasts of the field, they seek the satisfaction of the needs of the moment, without much forethought, and without considering that by sufficient effort the whole conditions of their lives could be changed.

Come the Day of Judgment, some believe that the body will be different from our present body. This is only transient, that will be eternal. For this also there are religious arguments.

The primary indication, to my thinking, of a well-ordered mind is a man's ability to remain in one place and linger in his own company.

If reason (I mean abstract reason, derived from inquiries a priori) be not alike mute with regard to all questions concerning cause and effect, this sentence at least it will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much, as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject, which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition, which is not common to both of them.

What would you say of that man who was made king by the error of the people, if he had so far forgotten his natural condition as to imagine that this kingdom was due to him, that he deserved it, and that it belonged to him of right? You would marvel at his stupidity and folly. But is there less in the people of rank who live in so strange a forgetfulness of their natural condition?

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

People from a planet without flowers would think we must be mad with joy the whole time to have such things about us.

The executive of the modern State is but a committee for managing the common affairs of the whole bourgeoisie.

Nothing can well be imagined more painful than the present position of woman, unless, on the one hand, she renounces all outward activity and keeps herself within the magic sphere, the bubble of her dreams; or, on the other, surrendering all aspiration, she gives herself to her real life, soul and body. For those to whom it is possible, the latter is best; for out of activity may come thought, out of mere aspiration can come nothing.

These Lectures, conjoined with those which have already appeared under the titles of "The Characteristics of the Present Age," and "The Nature of the Scholar," in the latter of which the tone of thought that governs the present course is applied to a particular subject, form a complete scheme of popular instruction, of which the present work exhibits the highest and clearest summit; and, taken together, they are the result of a process of self-culture, unceasingly pursued during the last six or seven years of my life, with greater leisure and in riper maturity, by means of that Philosophy in which I have been a partaker for thirteen years, and which, although, I hope, it has changed many things in me, has nevertheless itself suffered no change whatever during that period.

The bourgeoisie ... lets him have the appearance of acting from a free choice, of making a contract with free, unconstrained consent, as a responsible agent who has attained his majority. Fine freedom, where the proletarian has no other choice than that of either accepting the conditions which the bourgeoisie offers him, or of starving, of freezing to death, of sleeping naked among the beasts of the forests!

Where there is politics or economics, there is no morality.

The customs of that most criminal nation have gained such strength that they have now been received in all lands. The conquered have given laws to the conquerors.

The primary error of the advocates of land nationalization is in their confusion of equal rights with joint rights, and in their consequent failure to realize the nature and meaning of economic rent... In truth the right to the use of land is not a joint or common right, but an equal right; the joint or common right is to rent, in the economic sense of the term. Therefore it is not necessary for the state to take land, it is only necessary for it to take rent. This taking by the commonalty of what is of common right, would of itself secure equality in what is of equal right - for since the holding of land could be profitable only to the user, there would be no inducement for any one to hold land that he could not adequately use, and monopolization being ended no one who wanted to use land would have any difficulty in finding it.

The fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.

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.

Facts do not cease to exist because they are ignored.
