The doors of heaven and hell are adjacent and identical.

If we demonstrate this moving principle, if we show that matter, far from being as indifferent as it is supposed to be, to movement and to rest, ought to be regarded as an active, as well as a passive substance, what resource can be left to those who have made its essence consist in extension?

The good life, as I conceive it, is a happy life. I do not mean that if you are good you will be happy; I mean that if you are happy you will be good.

It cannot be doubted, I think, that Mr. Darwin has satisfactorily proved that what he terms selection, or selective modification, must occur, and does occur, in nature; and he has also proved to superfluity that such selection is competent to produce forms as distinct, structurally, as some genera even are. If the animated world presented us with none but structural differences, I should have no hesitation in saying that Mr. Darwin has demonstrated the existence of a true physical cause, amply competent to account for the origin of living species, and of man among the rest.

Paradise on earth is where I am.

The surest means of not losing your mind on the spot: remembering that everything is unreal, and will remain so...

The new governmental reason does not deal with what I would call the things in themselves of governmentality, such as individuals, things, wealth, and land. It no longer deals with these things in themselves. It deals with the phenomena of politics, that is to say, interests, which precisely constitute politics and its stakes; it deals with interests, or that respect in which a given individual, thing, wealth, and so on interests other individuals or the collective body of individuals. ... In the new regime, government is basically no longer to be exercised over subjects and other things subjected through these subjects. Government is now to be exercised over what we could call the phenomenal republic of interests. The fundamental question of liberalism is: What is the utility value of government and all actions of government in a society where exchange determines the value of things?

I do not, therefore, need any penetrating acuteness to see what I have to do in order that my volition be morally good. Inexperienced in the course of the world, incapable of being prepared for whatever might come to pass in it, I ask myself only: can you also will that your maxim become a universal law?

Space, subjectively, is the coexistence of perceptions - perceiving two objects at once.

If a philosopher is not a man, he is anything but a philosopher; he is above all a pedant, and a pedant is a caricature of a man. The cultivation of any branch of science - of chemistry, of physics, of geometry, of philology - may be a work of differentiated specialization, and even so, only within very narrow limits and restrictions; but philosophy, like poetry, is a work of integration and synthesis, or else it is merely pseudo-philosophical erudition.

The country that is more developed industrially only shows, to the less developed, the image of its own future.

The rise of new science in the seventeenth century laid hold upon general culture in the next century. The enlightenment... testified to the widespread belief that at last light had dawned, that dissipation of ignorance, superstition, and bigotry was at hand, and the triumph of reason was assured -- for reason was counterpart in man of the laws of nature which science was disclosing. The reign of law in the natural world was to be followed by the reign of law in human affairs.

The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

Foxes have their dens and birds have their nests, but human beings have no place to lay down and rest.

Media are means of extending and enlarging our organic sense lives into our environment.

A democratic government is the only one in which those who vote for a tax can escape the obligation to pay it.

If you act externally with men in conformity with your rank, you should recognize, by a more secret but truer thought, that you have nothing naturally superior to them.

I am attached to Christianity at large; much from conviction; more from affection.

Legislative reform and revolution are not different methods of historic development that can be picked out at the pleasure from the counter of history, just as one chooses hot or cold sausages. Legislative reform and revolution are different factors in the development of class society. They condition and complement each other, and are at the same time reciprocally exclusive, as are the north and south poles, the bourgeoisie and proletariat.

There cannot be a greater rudeness, than to interrupt another in the current of his discourse... To which, if there be added, as is usual, a correcting of any mistake, or a contradiction of what has been said, it is a mark of yet greater pride and self-conceitedness, when we thus intrude our selves for teachers, and take upon us either to set another right in his story, or shew the mistakes of his judgement.

We think in generalities, but we live in detail. To make the past live, we must perceive it in detail in addition to thinking of it in generalities.

Every way of classifying a thing is but a way of handling it for some particular purpose.

Men gather the clouds, and then they complain of the tempests that follow.

Kierkegaard writes: If Christianity were so easy and cozy, why should God in his Scriptures have set Heaven and Earth in motion and threatened eternal punishments? - Question: But then in that case why is this Scriptures so unclear?

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.

People who live at the lower ends of watersheds cannot be isolationists - or not for long. Pretty soon they will notice that water flows, and that will set them to thinking about the people upstream who either do or do not send down their silt and pollutants and garbage. Thinking about the people upstream out to cause further thinking about the people downstream. Such pondering on the facts of gravity and the fluidity of water shows us that the golden rule speaks to a condition of absolute interdependency and obligation. People who live on rivers - or, in fact, anywhere in a watershed - might rephrase the rule in this way: Do unto those downstream as you would have those upstream do unto you.

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.

All greatness is unconscious, or it is little and naught.

But it is better to assume principles less in number and finite, as Empedocles makes them to be. All philosophers... make principles to be contraries... (for Parmenides makes principles to be hot and cold, and these he demominates fire and earth) as those who introduce as principles the rare and the dense. But Democritus makes the principles to be the solid and the void; of which the former, he says, has the relation of being, and the latter of non-being. ...it is necessary that principles should be neither produced from each other, nor from other things; and that from these all things should be generated. But these requisites are inherent in the first contraries: for, because they are first, they are not from other things; and because they are contraries, they are not from each other.

Stupidity or reason? Oh, there was no choice now. It was imbecility every time.

The most simple picture one can form about the creation of an empirical science is along the lines of an inductive method. Individual facts are selected and grouped together such that their lawful connection becomes clearly apparent. ... The truly great advances in our understanding of nature originated in a manner almost diametrically opposed to induction. The intuitive grasp of the essentials or a large complex of facts leads the scientist to the postulation of a hypothetical basic law, or several such basic laws. From the basic laws (system of axioms) he derives his conclusions as completely as possible in a purely logically deductive manner. These conclusions, derived from the basic laws (and often only after time-consuming developments and calculations), can then be compared to experience, and in this manner provide criteria for the justification of the assumed basic law.

Disturbance comes only from within-from our own perceptions.

In speaking of the move from subjective to objective characterization, I wish to remain noncommittal about the existence of an endpoint, the completely objective intrinsic nature of the thing, which one might or might not be able to reach. It may be more accurate to think of objectivity as a direction in which the understanding can travel. And in understanding a phenomenon like lightning, it is legitimate to go as far away as one can from a strictly human viewpoint.But in the case of experience, on the other hand, the connexion with a particular point of view seems much closer. It is difficult to understand what could be meant by the objective character of an experience, apart from the particular point of view from which its subject apprehends it. After all, what would be left of what it was like to be a bat if one removed the viewpoint of the bat?

Once the needs of hunger are satisfied - and they are soon satisfied - the vanity, the necessity - for it is a necessity - arises of imposing ourselves upon and surviving in others. Man habitually sacrifices his life to his purse, but he sacrifices his purse to his vanity. He boasts even of his weakness and his misfortunes, for want of anything better to boast of, and is like a child who, in order to attract attention, struts about with a bandaged finger.

So long as you "have" yourself, have yourself as an object, your experience of man is only as of a thing among things.

So many men are deprived of grace. How can one live without grace? One has to try it and do what Christianity never did: be concerned with the damned.

The moral sense, or conscience, is as much a part of man as his leg or arm. It is given to all human beings in a stronger or weaker degree, as force of members is given them in a greater or less degree. It may be strengthened by exercise, as may any particular limb of the body. This sense is submitted, indeed, in some degree, to the guidance of reason; but it is a small stock which is required for this: even a less one than what we call common sense. State a moral case to a ploughman and a professor. The former will decide it as well, and often better than the latter, because he has not been led astray by artificial rules.

The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. WORKING MEN OF ALL COUNTRIES, UNITE!

Eventually, I believe, current attempts to understand the mind by analogy with man-made computers that can perform superbly some of the same external tasks as conscious beings will be recognized as a gigantic waste of time.

The superior man has neither anxiety nor fear. When internal examination discovers nothing wrong, what is there to be anxious about, what is there to fear?

In the realm of physics it is perhaps only the theory of relativity which has made it quite clear that the two essences, space and time, entering into our intuition, have no place in the world constructed by mathematical physics. Colours are thus "really" not even æther-vibrations, but merely a series of values of mathematical functions in which occur four independent parameters corresponding to the three dimensions of space, and the one of time.

Something that is merely negative creates nothing.

It is the safest to be moderately base - to be flexible in shame, and to be always ready for what is generous, good, and just, when anything is to be gained by virtue.

Anyone can escape into sleep, we are all geniuses when we dream, the butcher's the poet's equal there.

Slavery is disheartening; but Nature is not so helpless but it can rid itself of every last wrong. But the spasms of nature are centuries and ages and will tax the faith of short-lived men. Slowly, slowly the Avenger comes, but comes surely. The proverbs of the nations affirm these delays, but affirm the arrival. They say, "God may consent, but not forever." The delay of the Divine Justice - this was the meaning and soul of the Greek Tragedy, - this was the soul of their religion.

All significant concepts of the modern theory of the state are secularized theological concepts not only because of their historical development-in which they were transferred from theology to the theory of the state, whereby, for example, the omnipotent God became the omnipotent lawgiver-but also because of their systematic structure, the recognition of which is necessary for a sociological consideration of these concepts. The exception in jurisprudence is analogous to the miracle in theology.
