The advantage of pure, and the disadvantage of impure air are experienced each time we breathe, and all who understand the causes of disease know that an impure atmosphere is most unfavourable to the enjoyment of health, and an efficient cause to shorten human existence within the natural life of man. It is therefore most desirable that decisive measures should be devised and generally adopted to ensure to all a pure atmosphere, in which to live during their lives.

...and if you are common, you can dress up as a woman, show you behind or write poems: there's nothing offensive about a naked behind if it's everybody's; each person will be mirrored in it.

Every good mathematician is at least half a philosopher, and every good philosopher is at least half a mathematician.

Unpleasant, even dangerous, qualities can be found in every nation and every individual: it is cruel to demand that the Jew be an exception. In him, these qualities may even be dangerous and revolting to an unusual degree; and perhaps the young stock-exchange Jew is altogether the most disgusting invention of mankind.

By Natura naturans we must understand what is in itself and is conceived through itself, or such attributes of substance as express an eternal and infinite essence, that is ... God, insofar as he is considered as a free cause. But by Natura naturata I understand whatever follows from the necessity of God's nature, or from God's attributes, that is, all the modes of God's attributes insofar as they are considered as things which are in God, and can neither be nor be conceived without God.

I spoke after Sasha, for an hour. I discussed the farce of a government undertaking to carry democracy abroad by suppressing the last vestiges of it at home. I took up the contention of Judge Mayer that only such ideas are permissible as are "within the law." Thus he had instructed the jurymen when he had asked them if they were prejudiced against those who propagate unpopular ideas. I pointed out that there had never been an ideal, however humane and peaceful, which in its time had been considered "within the law." I named Jesus, Socrates, Galileo, Giordano Bruno. "Were they 'within the law"?" I asked. "And the men who set America free from British rule, the Jeffersons and the Patrick Henrys? The William Lloyd Garrisons, the John Browns, the David Thoreaus and Wendell Phillipses-were they within the law?"

Erosion of our being by our infirmities: the resulting void is filled by the presence of consciousness, what am I saying? - that void is consciousness itself.

If there were only one religion in England there would be danger of despotism, if there were two they would cut each other's throats, but there are thirty, and they live in peace and happiness.

It is to this law that our souls must adjust themselves, this they should follow, this they should obey. Whatever happens, assume that it was bound to happen, and do not be willing to rail at Nature. That which you cannot reform, it is best to endure, and to attend uncomplainingly upon the God under whose guidance everything progresses; for it is a bad soldier who grumbles when following his commander.

The necessity of faith as an ingredient in our mental attitude is strongly insisted on by the scientific philosophers of the present day; but by a singularly arbitrary caprice they say that it is only legitimate when used in the interests of one particular proposition, - the proposition, namely, that the course of nature is uniform. That nature will follow to-morrow the same laws that she follows to-day is, they all admit, a truth which no man can know; but in the interests of cognition as well as of action we must postulate or assume it.

Ancient histories, as one of our wits has said, are but fables that have been agreed upon.

All that Mankind has done, thought, gained or been: it is lying as in magic preservation in the pages of Books.

All the problems that disturb us today-the cutting down of forests and the erosion of the soil; the emancipation of woman and the limitation of the family; the conservatism of the established, and the experimentalism of the unplaced, in morals, music, and government; the corruptions of politics and the perversions of conduct; the conflict of religion and science, and the weakening of the supernatural supports of morality; the war of the classes, the nations, and the continents; the revolutions of the poor against the economically powerful rich, and of the rich against the politically powerful poor; the struggle between democracy and dictatorship, between individualism and communism, between the East and the West-all these agitated, as if for our instruction, the brilliant and turbulent life of ancient Hellas. There is nothing in Greek civilization that does not illuminate our own.

The message of radio is one of violent, unified implosion and resonance.

If the sensation that precedes the present by half a second were still immediately before me, then on the same principle, the sensation preceding that would be immediately present, and so on ad infinitum. Now, since there is a time [period], say a year, at the end of which an idea is no longer ipso facto present, it follows that this is true of any finite interval, however short.

The detour to ideality leads to coinciding with oneself, that is, to certainty, which remains the guide and guarantee of the whole spiritual adventure of being.

An ardent affection for the human race makes enthusiastic characters eager to produce alteration in laws and governments prematurely. To render them useful and permanent, they must be the growth of each particular soil, and the gradual fruit of the ripening understanding of the nation, matured by time, not forced by an unnatural fermentation.

At the end of the Middle Ages, leprosy disappeared from the Western world. In the margins of the community, at the gates of cities, there stretched wastelands which sickness had ceased to haunt but had left sterile and long uninhabitable. For centuries, these reaches would belong to the non-human. From the fourteenth to the seventeenth century, they would wait, soliciting with strange incantations a new incarnation of disease, another grimace of terror, renewed rites of purification and exclusion.

I am too much of a sceptic to deny the possibility of anything - especially as I am now so much occupied with theology - but I don't see my way to your conclusion.

We are reformers in spring and summer; in autumn and winter we stand by the old - reformers in the morning, conservatives at night. Reform is affirmative, conservatism is negative; conservatism goes for comfort, reform for truth.

Intolerance is the besetting sin of moral fervour.

It is, therefore, quite natural that the churches have always fought against science and have persecuted its supporters. But, on the other hand, I assert that the cosmic religious experience is the strongest and noblest driving force behind scientific research. No one who does not appreciate the terrific exertions, and, above all, the devotion without which pioneer creations in scientific thought cannot come into being, can judge the strength of the feeling out of which alone such work, turned away as it is from immediate practical life, can grow. What a deep faith in the rationality of the structure of the world and what a longing to understand even a small glimpse of the reason revealed in the world there must have been in Kepler and Newton to enable them to unravel the mechanism of the heavens in long years of lonely work! Any one who only knows scientific research in its practical applications may easily come to a wrong interpretation of the state of mind of the men who, surrounded by skeptical contemporaries, have shown the way to kindred spirits scattered over all countries in all centuries. Only those who have dedicated their lives to similar ends can have a living conception of the inspiration which gave these men the power to remain loyal to their purpose in spite of countless failures. It is the cosmic religious sense which grants this power. A contemporary has rightly said that the only deeply religious people of our largely materialistic age are the earnest men of research.

To teach him betimes to love and be good-natur'd to others, is to lay early the true foundation of an honest man; all injustice generally springing from too great love of ourselves and too little of others.

I am sure that university life would be better, both intellectually and morally, if most university students had temporary childless marriages. This would afford a solution to the sexual urge neither restless nor surreptitious, neither mercenary nor casual, and of such a nature that it need not take up time which ought to be given to work.

If thou shalt aspire after the glorious acts of men, thy working shall be accompanied with compunction and strife, and thy remembrance followed with distaste and upbraidings; and justly doth it come to pass towards thee, O man, that since thou, which art God's work, doest him no reason in yielding him well-pleasing service, even thine own works also should reward thee with the like fruit of bitterness.

The preposterous distinction of rank, which render civilization a curse, by dividing the world between voluptuous tyrants and cunning envious dependents, corrupt, almost equally, every class of people, because respectability is not attached to the discharge of the relative duties of life, but to the station, and when the duties are not fulfilled, the affections cannot gain sufficient strength to fortify the virtue of which they are the natural reward. Still there are some loop-holes out of which a man may creep, and dare to think and act for himself; but for a woman it is an herculean task, because she has difficulties peculiar to her sex to overcome, which require almost super-human powers.

An unjust law is no law at all.

The Science of Hydrostatics depends upon the Fundamental Principle that 'fluids press equally in all directions'. This Principle necessarily results from the conception of a Fluid, as a body of which the parts are perfectly moveable in all directions. For since the Fluid is a body, it can transmit pressure; and the transmitted pressure is equal to the original pressure, in virtue of the Axiom that Reaction is equal to Action. That the Fundamental Principle is not derived from experience, is plain both from its evidence and from its history.

Ivan Ilych's life had been most simple and most ordinary and therefore most terrible.

To teach virtue we must educate the emotions, and this means learning "what to feel" in the various circumstances that prompt them.

What the great learning teaches, is to illustrate illustrious virtue; to renovate the people; and to rest in the highest excellence. The point where to rest being known, the object of pursuit is then determined; and, that being determined, a calm unperturbedness may be attained to. To that calmness there will succeed a tranquil repose. In that repose there may be careful deliberation, and that deliberation will be followed by the attainment of the desired end.

We've reached a truly remarkable situation: a grotesque mismatch between the American intelligentsia and the American electorate. A philosophical opinion about the nature of the universe which is held by the vast majority of top American scientists, and probably the majority of the intelligentsia generally, is so abhorrent to the American electorate that no candidate for popular election dare affirm it in public. If I'm right, this means that high office in the greatest country in the world is barred to the very people best qualified to hold it: the intelligentsia, unless they are prepared to lie about their beliefs. To put it bluntly American political opportunities are heavily loaded against those who are simultaneously intelligent and honest.

The world is rejuvenated, but as Heine so wittily remarked, it was rejuvenated by romanticism to such a degree that it became a baby again.

The tolls for the maintenance of a high road, cannot with any safety be made the property of private persons.

Take heed lest any man deceive you: For many shall come in my name, saying, I am Christ; and shall deceive many. And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows. But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. And the gospel must first be published among all nations. But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost.

Dialectical thought understands the critical tension between "is" and "ought" first as an ontological condition, pertaining to the structure of Being itself. However, the recognition of this state of Being - its theory - intends from the beginning a concrete practice. Seen in the light of a truth which appears in them falsified or denied, the given facts themselves appear false and negative.

My reason will still not understand why I pray, but I shall still pray, and my life, my whole life, independently of anything that may happen to me, is every moment of it no longer meaningless as it was before, but has an unquestionable meaning of goodness with which I have the power to invest it.

It is because you yourself fear the propaganda created, after all, only by the stupidity of your own bigots.

Artistic creation is a demand for unity and a rejection of the world.

The essential is to cease being free and to obey, in repentance, a greater rogue than oneself. When we are all guilty, that will be democracy.

That body is heavier than another which, in an equal bulk, moves downward quicker.

A physicist looks for causes; that does not necessarily imply that there are causes everywhere. A man may look for gold without assuming that there is gold everywhere; if he finds gold, well and good, if he doesn't he's had bad luck. The same is true when the physicists look for causes.

Ten thousand do not turn the scale against a single man of worth.
