Camus said there is only really one serious philosophical question, which is whether or not to commit suicide. I think there are four or five serious philosophical questions: The first one is: Who started it? The second is: Are we going to make it? The third is: Where are we going to put it? The fourth is: Who's going to clean up? And the fifth: Is it serious?

Some years ago, as Your Serene Highness well knows, I discovered in the heavens many things that had not been seen before our own age. The novelty of these things, as well as some consequences which followed from them in contradiction to the physical notions commonly held among academic philosophers, stirred up against me no small number of professors - as if I had placed these things in the sky with my own hands in order to upset nature and overturn the sciences. They seemed to forget that the increase of known truths stimulates the investigation, establishment, and growth of the arts; not their diminution or destruction.

What man calls Absolute Being, his God, is his own being. The power of the object over him is therefore the power of his own being. Thus, the power of the object of feeling is the power of feeling itself; the power of the object of reason is the power of reason itself; and the power of the object of will is the power of will itself.

Anything done against faith or conscience is sinful.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!', but 'That's funny ...'

It is necessary that every man be surpassingly temperate. That person would most of all be a man of this sort if he were superior to money, which is what corrupts all men, and if, without caring about his life, he bestowed his pains on things that are just and pursued virtue.

The mask, like the side-show freak, is mainly participatory rather than pictorial in its sensory appeal.

We hold, that the moral obligation of providing for old age, helpless infancy, and poverty, is far superior to that of supplying the invented wants of courtly extravagance, ambition and intrigue.

If we do not secure the foundation, we cannot secure the edifice.

Militarism in both its forms - as war and as armed peace - is a legitimate child, a logical result of capitalism, which can only be overcome with the destruction of capitalism, and that hence whoever honestly desires world peace and liberation from the tremendous burden of armaments must also desire Socialism. Only in this way can real Social Democratic enlightenment and recruiting be carried on in connection with the armaments debate.

Nature does nothing in vain, and in the use of means to her goals she is not prodigal. Her giving to man reason and the freedom of the will which depends upon it is clear indication of her purpose. Man accordingly was not to be guided by instinct, not nurtured and instructed with ready-made knowledge; rather, he should bring forth everything out of his own resources.

He was seized and dragged off to King Philip, and being asked who he was, replied, "A spy upon your insatiable greed."

Mere imagination would indeed be mere trifling; only no imagination is mere.

Thou shouldst not become presumptuous through life; for death comes upon thee at last, and the perishable part falls to the ground.

The next simplest feature that is common to all that comes before the mind, and consequently, the second category, is the element of Struggle.

Without some affinity in human ideas art would certainly be impossible; but it can never be exactly determined how far the intentions of the poet are realized.

Do not tell lies, and do not do what you hate, for all things are plain in the sight of Heaven. For nothing hidden will not become manifest, and nothing covered will remain without being uncovered.

Nothing is so firmly believed as what we least know.

I am not my soul.

The medieval peasant prior to the 13th century does not compare himself to the feudal lord, nor does the artisan compare himself to the knight. ... From the king down to the hangman and the prostitute, everyone is "noble" in the sense that he considers himself as irreplaceable. In the "system of free competition," on the other hand, the notions on life's tasks and their value are not fundamental, they are but secondary derivations of the desire of all to surpass all the others. No "place" is more than a transitory point in this universal chase.

Evil does not approach us as pride any more, but on the contrary as slumber, lassitude, concealment of the "I." ... It may make us so quickly contented, that any definitive fire will die down. The venomous, breathtaking frigid mist seems able ... to harden hearts and fill them with envy, obduracy and resentment, with bloody scorn for the divine image and light, with all the causes of the only true original sin, which is not wanting to be like God.

The art of writing books is not yet invented. But it is at the point of being invented. Fragments of this nature are literary seeds. There may be many an infertile grain among them: nevertheless, if only some come up!

To desire friendship is a great fault. Friendship should be a gratuitous joy like those afforded by art or life. We must refuse it so that we may be worthy to receive it; it is of the order of grace.

Avarice and injustice are always shortsighted, and they did not foresee how much this regulation must obstruct improvement, and thereby hurt in the long-run the real interest of the landlord.

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.

His Religion is not an easy one: with rigorous fasts, lavations, strict complex formulas, prayers five times a day, and abstinence from wine, it did not "succeed by being an easy religion." As if indeed any religion, or cause holding of religion, could succeed by that! It is a calumny on men to say that they are roused to heroic action by ease, hope of pleasure, recompense, - sugar-plums of any kind, in this world or the next! In the meanest mortal there lies something nobler.

In Matthew 12:23 Christ says: "Either make the tree good, and its fruit good; or make the tree bad and its fruit bad," as if to say: "Let the one who wishes to have good fruit begin by planting a good tree." Therefore, let the person who wishes to do good works being not with the works but with the believing, for this alone makes a person good.

He who has thought most deeply loves what is most alive.

History has proved us, and all who thought like us, wrong. It has made it clear that the state of economic development on the Continent at that time was not, by a long way, ripe for the removal of capitalist production.

In which the technical apparatus of production and distribution (with an increasing sector of automation) functions, not as the sum-total of mere instruments which can be isolated from their social and political effects, but rather as a system which determines a priori the product of the apparatus as well as the operations of servicing and extending it. In this society, the productive apparatus tends to become totalitarian to the extent to which it determines not only the socially needed occupations, skills, and attitudes, but also individual needs and aspirations. It thus obliterates the Opposition between the private and public existence, between individual and social needs.

What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift it out? How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days.

To shoot down a European is to kill two birds with one stone, to destroy an oppressor and the man he oppresses at the same time.

Somehow, the practice of astronomy, physics, chemistry or biology normally fails to evoke the controversies over fundamentals that today seem endemic among, say, psychologists or sociologists. Attempting to discover the source of that difference led me to recognize the role in scientific research of what I have since called "paradigms." These I take to be universally recognized scientific achievements that for a time provide model problems and solutions for a community of practitioners.

The universe itself is God and the universal outpouring of its soul.

Science fiction may be defined as that branch of literature which deals with the response of human beings to advances in science and technology. Actual change in science and technology, occurring quickly enough and striking deeply enough to affect a human being in the course of his normal lifetime, is a phenomenon peculiar to the world only since the Industrial Revolution ... The first well-known writer who responded to this new factor in human affairs by dealing regularly with science fiction, by studying the effect of additional scientific advance upon mankind ... was Jules Verne. In the English language, the early master was H. G. Wells. Between them, they laid the foundation for every theme upon which science fiction writers have been ringing variations ever since.

I frequently asked myself, if I could, or if I was bound to go on living, when life must be passed in this manner. I generally answered to myself, that I did not think I could possibly bear it beyond a year.

'Induction' is a term applied to describe the 'process' of a true Colligation of Facts by means of an exact and appropriate Conception. 'An Induction' is also employed to denote the 'proposition' which results from this process. An Induction is not the mere sum of the Facts which are colligated. The Facts are not only brought together, but seen in a new point of view. 'The Consilience of Inductions' takes place when an Induction, obtained from one class of facts, coincides with an Induction, obtained from another different class.

The mother tongue is propaganda.

The introduction of numbers as coordinates by reference to the particular division scheme of the open one dimensional continuum is an act of violence whose only practical vindication is the special calculatory manageability of the ordinary number continuum with its four basic operations. The topological skeleton determines the connectivity of the manifold in the large.

If you do the job in a principled way, with diligence, energy and patience, if you keep yourself free of distractions, and keep the spirit inside you undamaged, as if you might have to give it back at any moment- If you can embrace this without fear or expectation-can find fulfillment in what you're doing now, as Nature intended, and in superhuman truthfulness (every word, every utterance)-then your life will be happy.

France has always more or less influenced manners in England; and when your fountain is choked up and polluted, the stream will not run long, or not run clear, with us, or perhaps with any nation. This gives all Europe, in my opinion, but too close and connected a concern in what is done in France. Excuse me, therefore, if I have dwelt too long on the atrocious spectacle of the 6th of October, 1789, or have given too much scope to the reflections which have arisen in my mind on occasion of the most important of all revolutions, which may be dated from that day, I mean a revolution in sentiments, manners, and moral opinions.

No one commits suicide for external reasons, only because of inner disequilibrium. Under similar adverse circumstances, some are indifferent, some are moved, some are driven to suicide.

Is not my present nearer my past of yesterday than the present of Sirius?

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.

I shall cheerfully bear the reproach of having descended below the dignity of history if I can succeed in placing before the English of the nineteenth century a true picture of the life of their ancestors.

National character is only another name for the particular form which the littleness, perversity and baseness of mankind take in every country. Every nation mocks at other nations, and all are right. Variant translation: Every nation criticizes every other one - and they are all correct.

We attest that He is the Willer of all things that are, the ruler of all originated phenomena; there does not come into the visible or invisible world anything meager or plenteous, small or great, good or evil, or any advantage or disadvantage, belief or unbelief, knowledge or ignorance, success or failure, increase or decrease, obedience or disobedience, except by His will. What He wills is, and what He does not, will not; there is not a glance of the eye, nor a stray thought of the heart that is not subject to His will. He is the Creator, the Restorer, the Doer of whatsoever He wills. There is none that rescinds His command, none that supplements His decrees, none that dissuades a servant from disobeying Him, except by His help and mercy, and none has power to obey Him except by His will.
