In our contemporary social and intellectual plight, it is nothing less than shocking to discover that those persons who claim to have discovered an absolute are usually the same people who also pretend to be superior to the rest. To find people in our day attempting to pass off to the world and recommending to others some nostrum of the absolute which they claim to have discovered is merely a sign of the loss of and the need for intellectual and moral certainty, felt by broad sections of the population who are unable to look life in the face.

To the man who is truly ethical all life is sacred, including that which from the human point of view seems lower in the scale. He makes distinctions only as each case comes before him, and under the pressure of necessity, as, for example, when it falls to him to decide which of two lives he must sacrifice in order to preserve the other. But all through this series of decisions he is conscious of acting on subjective grounds and arbitrarily, and knows that he bears the responsibility for the life which is sacrificed.

Of all human and ancient opinions concerning religion, that seems to me the most likely and most excusable, that acknowledged God as an incomprehensible power, the original and preserver of all things, all goodness, all perfection, receiving and taking in good part the honour and reverence that man paid him, under what method, name, or ceremonies soever

You have already grasped that Sisyphus is the absurd hero. He is, as much through his passions as through his torture. His scorn of the gods, his hatred of death, and his passion for life won him that unspeakable penalty in which the whole being is exerted toward accomplishing nothing. This is the price that must be paid for the passions of this earth. Nothing is told us about Sisyphus in the underworld. Myths are made for the imagination to breathe life into them.

You rejoice in having made a convert to Atheism. I think there is something unnatural in a zeal of proselytism in an Atheist. I do not believe in an intellectual God, a God made after the image of man. In the vulgar acceptation of the word, therefore, I think a man is right who does not believe in God, but I am also persuaded that a man is wrong who is without religion.

The pessimist has to invent new reasons to exist every day: he is a victim of the "meaning" of life.

No theory, no ready-made system, no book that has ever been written will save the world. I cleave to no system. I am a true seeker.

Wherever your life ends, it is all there. The utility of living consists not in the length of days, but in the use of time; a man may have lived long, and yet lived but a little. Make use of time while it is present with you. It depends upon your will, and not upon the number of days, to have a sufficient length of life. Is it possible you can imagine never to arrive at the place towards which you are continually going? and yet there is no journey but hath its end. And, if company will make it more pleasant or more easy to you, does not all the world go the self-same way?

And neither ought we to be surprised by the affirmation that the consciousness of the Universe is composed and integrated by the consciousnesses of the beings which form the Universe, by the consciousnesses of all the beings that exist, and that nevertheless it remains a personal consciousness distinct from those which compose it. Only thus is it possible to understand how in God we live, move, and have our being.

How many things served us yesterday for articles of faith, which today are fables for us?

Organic life, we are told, has developed gradually from the protozoon to the philosopher, and this development, we are assured, is indubitably an advance. Unfortunately it is the philosopher, not the protozoon, who gives us this assurance.

The real sin - perhaps it is a sin against the Holy Ghost for which there is no remission - is the sin of heresy, the sin of thinking for oneself. The saying has been heard before now, here in Spain, that to be a liberal - that is, a heretic - is worse than being an assassin, a thief, or an adulterer. The gravest sin is not to obey the Church, whose infallibility protects us from reason.

The indispensible is not necessarily the desirable.

An organised system of machines, to which motion is communicated by the transmitting mechanism from a central automation, is the most developed form of production by machinery.

The idea that in order to get clear about the meaning of a general term one had to find the common element in all its applications has shackled philosophical investigation; for it has not only led to no result, but also made the philosopher dismiss as irrelevant the concrete cases, which alone could have helped him understand the usage of the general term.

Human intuitions are systematically biased. Evolutionary psychology explains how our moral intuitions and the rationalisations they spawn have been shaped by millennia of natural selection to maximise the inclusive fitness of our genes, not to track the welfare of other sentient beings impartially conceived. Many human cultures have found nothing intuitively wrong with aggressive warfare, slavery, wife-beating, infanticide or female genital mutilation. Ultimately, folk morality is a doomed enterprise as hopeless as folk physics. A mature posthuman ethics, I'd argue, must be committed to the well-being of all sentient life; and mature posthuman technology offers the means to deliver that commitment.

The aim of research is the discovery of the equations which subsist between the elements of phenomena.

The idea of universal human dignity ultimately comes out of Christianity... the view that all human beings are equal in the sight of God because they have the capacity for moral choice. As Western thought developed in the 17th-18th centuries, this took on a secular form under thinkers like Jean-Jacques Rousseau or Immanuel Kant or Georg Hegel, who argued that human equality is... based on human autonomy.

Nationalism is always an effort in a direction opposite to that of the principle which creates nations. The former is exclusive in tendency, the latter inclusive. In periods of consolidation, nationalism has a positive value, and is a lofty standard. But in Europe everything is more than consolidated, and nationalism is nothing but a mania, a pretext to escape from the necessity of inventing something new, some great enterprise.

The person who screams, or uses the superlative degree, or converses with heat, puts whole drawing-rooms to flight. If you wish to be loved, love measure. You must have genius or a prodigious usefulness if you will hide the want of measure.

If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!

We only labor to stuff the memory, and leave the conscience and the understanding unfurnished and void.

These immense cities lie basking on the beaches of the continent like whales that have taken to the land again. What do these great, sleek, well-fed creatures live on so sumptuously?

The notion that one can discover large patterns or regularities in the procession of historical events is naturally attractive to those who are impressed by the success of the natural sciences in classifying, correlating, and above all predicting.

Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second and you can hop from one place to another. It's a language made of image. And in the real cinema, every object and every light means something, as in a dream.

The eye may see for the hand, but not for the mind.

In the case of most pains let this remark of Epicurus aid thee, that the pain is neither intolerable nor everlasting, if thou bear in mind that it has its limits, and if thou addest nothing to it in imagination…

To succeed, planning alone is insufficient. One must improvise as well.

You worry whether the drought will end. It is far better that you pray that God may water your mind lest virtue wither away in it. You are greatly concerned with money that is lost or being wasted, or you worry about the advance of old age. I think it much to be desired that you provide first of all for the needs of your soul.

The souls of emperors and cobblers are cast in the same mould.... The same reason that makes us wrangle with a neighbour causes a war betwixt princes.

Movement in direct experience is alteration in the qualities of objects, and space as experienced is an aspect of this qualitative change. Up and down, back and front, to and fro, this side and that- or right and left- here and there, feel differently. The reason they do is that they are not static points in something itself static, but objects in movement, qualitative changes of value. For "back" is short for backwards and front for forwards. So with velocity. Mathematically there are no such things as fast and slow. They mark simply greater and less on a number scale. As experienced they are qualitatively as unlike as noise and silence, heat and cold, black and white. To be forced to wait a long time for an important event to happen is a length very different from that measured by the movements of the hands of a clock. It is something qualitative.

It's hard for writers to get on with their work if they are convinced that they owe a concrete debt to experience and cannot allow themselves the privilege of ranging freely through social classes and professional specialties. A certain pride in their own experience, perhaps a sense of the property rights of others in their experience, holds them back.

We took the liberty to make some enquiries concerning the ground of their pretensions to make war upon nations who had done them no injury, and observed that we considered all mankind as our friends who had done us no wrong, nor had given us any provocation. The Ambassador [of Tripoli] answered us that it was founded on the Laws of their Prophet, that it was written in their Koran, that all nations who should not have acknowledged their authority were sinners, that it was their right and duty to make war upon them wherever they could be found, and to make slaves of all they could take as Prisoners, and that every Musselman who should be slain in battle was sure to go to Paradise.

The soul is the prison of the body.

Opinions differ as to the reasons why he became the futile laborer of the underworld. To begin with, he is accused of a certain levity in regard to the gods. He stole their secrets.

Democracy is the process by which people choose the man who'll get the blame.

The book written against fame and learning has the author's name on the title-page.

We are but numbers, born to consume resources.

I have received, sir, your new book against the human species, and I thank you for it. You will please people by your manner of telling them the truth about themselves, but you will not alter them. The horrors of that human society-from which in our feebleness and ignorance we expect so many consolations-have never been painted in more striking colours: no one has ever been so witty as you are in trying to turn us into brutes: to read your book makes one long to go on all fours. Since, however, it is now some sixty years since I gave up the practice, I feel that it is unfortunately impossible for me to resume it: I leave this natural habit to those more fit for it than are you and I.

In an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.

Ads represent the main channel of intellectual and artistic effort in the modern world.

There are, in fact, people who appear to think only with the brain, or with whatever may be the specific thinking organ; while others think with all the body and all the soul, with the blood, with the marrow of the bones, with the heart, with the lungs, with the belly, with the life. And the people who think only with the brain develop into definition-mongers; they become the professionals of thought.

I go to spread the tidings, I want to spread the tidings - of what? Of the truth, for I have seen it, have seen it with my own eyes, have seen it in all its glory.

The "passion for incredulity" can produce as much self-deception as the uncritical will to believe.

"You err, not knowing the Scriptures nor the power of God" This canon is the mother of all canons against heresy; the causes of error are two; the ignorance of the will of God, and the ignorance or not sufficient consideration of his power.

Ideas are invented only as correctives to the past. Through repeated rectifications of this kind one may hope to disengage an idea that is valid.

My life - I had lived in its heights and its depths, in bitter sorrow and ecstatic joy, in black despair and fervent hope. I had drunk the cup to the last drop. I had lived my life. Would I had the gift to paint the life I had lived!

Art, at least, teaches us that man cannot be explained by history alone and that he also finds a reason for his existence in the order of nature.
