While the positivists were proclaiming the end "once and for all" of unverifiable metaphysical systems and speculative philosophy in general, new doctrines in flagrant contradiction to those ideals have sprung up one after the other. Positivists see no more in this development than evidence of human stupidity, not any reflection on themselves.

Men do not lead the revolution; it is the Revolution that uses men. They are right when they say it goes all alone. This phrase means that never has the Divinity shown itself so clearly in any human event. If the vilest instruments are employed, punishment is for the sake of regeneration.

That which exercises reason is more excellent than that which does not exercise reason; there is nothing more excellent than the universe, therefore the universe exercises reason.

There are men and gods, and beings like Pythagoras.

They are in bad faith - they are afraid - and fear, bad faith have an aroma that the gods find delicious. Yes, the gods like that, the pitiful souls.

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.

The mind must be indulged, and leisure must be given from time to time, which is the place of food and strength.

True hedonic engineering, as distinct from mindless hedonism or reckless personal experimentation, can be profoundly good for our character. Character-building technologies can benefit utilitarians and non-utilitarians alike. Potentially, we can use a convergence of biotech, nanorobotics and information technology to gain control over our emotions and become better (post-)human beings, to cultivate the virtues, strength of character, decency, to become kinder, friendlier, more compassionate: to become the type of (post)human beings that we might aspire to be, but aren't, and biologically couldn't be, with the neural machinery of unenriched minds. Given our Darwinian biology, too many forms of admirable behaviour simply aren't rewarding enough for us to practise them consistently: our second-order desires to live better lives as better people are often feeble echoes of our baser passions.

Experience is what you get while looking for something else.

Newton, and 'proper scientific method' after him, conducted attention to 'continuous description' of experimental phenomena instead of to causes.

It is truly not the merit of the school if we do not come out selfish. Each sort of corresponding pride and every wind of covetousness, eagerness for office, mechanical and servile officiousness, hypocrisy, etc., is bound as much with extensive knowledge as with elegant, classical education, and since this whole instruction exercises no influence of any sort on our ethical behavior, it thus frequently falls to the fate of being forgotten in the same measure as it is not used: one shakes off the dust of the school.

Paper is poverty,... it is only the ghost of money, and not money itself.

Both Stoicism and Epicureanism - the apathetic acceptance of defeat, and the effort to forget defeat in the arms of pleasure - were theories as to how one might yet be happy though subjugated or enslaved; precisely as the stoicism of Schopenhauer and the despondent epicureanism of Renan were in the nineteenth century the symbols of a shattered revolution and a broken France.

Newton's law is nothing but the statistics of gravitation, it has no power whatever. Let us get rid of the idea of power from law altogether. Call law tabulation of facts, expression of facts, or what you will; anything rather than suppose that it either explains or compels.

When we see civilization elated with this declining and decrepit phase of its career, we are reminded of a faded belle who, boasting of her attractions in her fiftieth year, excites at once the remark that she was fairer at twenty-five. So it is with civilization, which, dreaming of perfection and progress, is constantly deteriorating, and which will find but too soon in its industrial achievements new sources of political oppression, crimes and commotions.

In ourselves alone the absolute light keeps shining, a sigillum falsi et sui, mortis et vitae aeternae [false signal and signal of eternal life and death itself], and the fantastic move to it begins: to the external interpretation of the daydream, the cosmic manipulation of a concept that is utopian in principle. Finding this concept, finding the right for whose sake it behoves us to live, to be organized, to have time-this is where we are headed, why we are clearing the metaphysically constitutive trails afresh, calling for what is not, building into the blue that lines all edges of the world; this is why we build ourselves into the blue and search for truth and reality where mere factuality vanishes.

All grandeur, all power, all subordination to authority rests on the executioner: he is the horror and the bond of human association. Remove this incomprehensible agent from the world and at that very moment order gives way to chaos, thrones topple and society disappears.

I must confess that my estimate of Lovecraft would not have pleased his most ardent admirers. The view I expressed in that book was that, while Lovecraft was distinctly a creative genius in his own way, his pessimism should not be taken too seriously; that it was the pessimism of a sick recluse, and had about it an element of rassentiment, a kind of desire to take revenge on the world that rejected him. In short, Lovecraft was a 19th century romantic, born in the wrong time. Most men of genius dislike their own age, but the really great ones impose their own vision on the age. The weak ones turn away into a world of gloomy fantasy.

Every subjective phenomenon is essentially connected with a single point of view, and it seems inevitable that an objective physical theory will abandon that point of view.

The consciousness of brutes would appear to be related to the mechanism of their body simply as a collateral product of its working, and to be as completely without any power of modifying that working as the steam-whistle which accompanies the work of a locomotive engine is without influence upon its machinery. Their volition, if they have any, is an emotion indicative of physical changes, not a cause of such changes.

Animals no doubt have different interests from humans, and may experience different pleasures and pains, but the principle of equal consideration for similar interests still holds, and pleasures and pains of similar intensity and duration should be given equal weight, whether they are experienced by humans or by animals.

Religion comforts us for the defeat of our will to power. It adds new worlds to ours, and thus brings us hope of new conquests and new victories. We are converted to religion out of fear of suffocating within the narrow confines of this world.

One might expect that a consideration of grievability pertains only to those who are dead, but my contention is that grievability is already operative in life, and that it is a characteristic attributed to living creatures, marking their value within a differential scheme of values and bearing directly on the question of whether or not they are treated equally and in a just way. To be grievable is to be interpellated in such a way that you know your life matters; that the loss of your life would matter; that your body is treated as one that should be able to live and thrive, whose precarity should be minimized, for which provisions for flourishing should be available. The presumption of equal grievability would be not only a conviction or attitude with which another person greets you, but a principle that organizes the social organization of health, food, shelter, employment, sexual life, and civic life.

“What man among you with 100 sheep, on losing one of them, will not leave the 99 behind in the wilderness and go after the lost one until he finds it? And when he has found it, he puts it on his shoulders and rejoices. And when he gets home, he calls his friends and his neighbors together, saying to them, ‘Rejoice with me, for I have found my sheep that was lost.' I tell you that in the same way, there will be more joy in heaven over one sinner who repents than over 99 righteous ones who have no need of repentance.

No longer enslaved or made dependent by force of law, the great majority are so by force of poverty; they are still chained to a place, to an occupation, and to conformity with the will of an employer, and debarred, by the accident of birth both from the enjoyments, and from the mental and moral advantages, which others inherit without exertion and independently of desert. That this is an evil equal to almost any of those against which mankind have hitherto struggled, the poor are not wrong in believing.

Kindly remember that he whom you call your slave sprang from the same stock, is smiled upon by the same skies, and on equal terms with yourself breathes, lives and dies. It is just as possible for you to see in him a free-born man as for him to see in you a slave.

Our island is this earth; and the most striking object we behold is the sun. As soon as we pass beyond our immediate surroundings, one or both of these must meet our eye. Thus the philosophy of most savage races is mainly directed to imaginary divisions of the earth or to the divinity of the sun.

The Palaetiological Sciences point backwards with lines which are broken, but which all converge to the 'same' invisible point: and this point is the Origin of the Moral and Spiritual, as well as of the natural world.

There is a certain kind of morality which is even more alien to good and evil than amorality is.

Feeling which has not yet emerged into immediate consciousness is already affectible and already affected. In fact, this is habit, by virtue of which an idea is brought up into the present consciousness by a bond that has already been established between it and another idea while it was still in futuro.

Reason has never really directed social reality, but now reason has been so thoroughly purged of any specific trend or preference that it has finally renounced even the task of passing judgment on man's actions and way of life. Reason has turned them over for ultimate sanction to the conflicting interests to which our world actually seems abandoned.

The name of a man is a numbing blow from which he never recovers.

I knew a parson who frightened his congregation terribly by telling them that the second coming was very imminent indeed, but they were much consoled when they found that he was planting trees in his garden.

He [God] lends us a little of His reasoning powers and that is how we think: He puts a little of His love into us and that is how we love one another. When you teach a child writing, you hold its hand while it forms the letters: that is, it forms the letters because you are forming them. We love and reason because God loves and reasons and holds our hand while we do it.

Let us not underrate the value of a fact; it will one day flower in a truth.

In a word, neither death, nor exile, nor pain, nor anything of this kind is the real cause of our doing or not doing any action, but our inward opinions and principles.

To theology, ... only what it holds sacred is true, whereas to philosophy, only what holds true is sacred.

How many women does one need to sing the scale of love all the way up and down?

Moreover, there is a victory and defeat, the first and best of victories, the lowest and worst of defeat, which each man gains or sustains at the hands, not of another, but of himself; this shows that there is a war against ourselves going on within every one of us. Book I Sometimes paraphrased as "The first and best victory is to conquer self".

What you see, yet can not see over, is as good as infinite.

Now his principal doctrines were these. That atoms and the vacuum were the beginning of the universe; and that everything else existed only in opinion.

How many, once lauded in song, are given over to the forgotten; and how many who sung their praises are clean gone long ago!

In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were an angel of the Lord to come and drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him. I am quite aware that we have just now lightheartedly expelled in imagination many excellent men who are largely, perhaps chiefly, responsible for the buildings of the temple of science; and in many cases, our angel would find it a pretty ticklish job to decide. But of one thing I feel sure: if the types we have just expelled were the only types there were, the temple would never have come to be, any more than a forest can grow which consists of nothing but creepers. For these people any sphere of human activity will do if it comes to a point; whether they become engineers, officers, tradesmen, or scientists depends on circumstances.Now let us have another look at those who have found favor with the angel. Most of them are somewhat odd, uncommunicative, solitary fellows, really less like each other, in spite of these common characteristics, than the hosts of the rejected. What has brought them to the temple? That is a difficult question and no single answer will cover it.

To understand the actual world as it is, not as we should wish it to be, is the beginning of wisdom.

Scientists work from models acquired through education and through subsequent exposure to the literature often without quite knowing or needing to know what characteristics have given these models the status of community paradigms.

The meaning of a question is the method of answering it: then what is the meaning of 'Do two men really mean the same by the word "white"?' Tell me how you are searching, and I will tell you what you are searching for.

We often have need of a profound philosophy to restore to our feelings their original state of innocence, to find our way out of the rubble of things alien to us, to begin to feel for ourselves and to speak ourselves, and I might almost say to exist ourselves. Even if my philosophy does not extend to discovering anything new, it does nevertheless possess the courage to regard as questionable what has long been thought true.
