History warns us, however, that it is the customary fate of new truths to begin as heresies and to end as superstitions; and, as matters now stand, it is hardly rash to anticipate that, in another twenty years, the new generation, educated under the influences of the present day, will be in danger of accepting the main doctrines of the 'Origin of Species' with as little reflection, and it may be with as little justification, as so many of our contemporaries, twenty years ago, rejected them. Against any such a consummation let us all devoutly pray; for the scientific spirit is of more value than its products, and irrationally held truths may be more harmful than reasoned errors.

It is often said that experiments should be made without preconceived ideas. That is impossible. Not only would it make every experiment fruitless, but even if we wished to do so, it could not be done. Every man has his own conception of the world, and this he cannot so easily lay aside. We must, for example, use language, and our language is necessarily steeped in preconceived ideas.

Learning will be cast into the mire and trodden down under the hoofs of a swinish multitude.

If...we look at the essential characteristics of the Whig and the Tory, we may consider each of them as the representative of a great principle, essential to the welfare of nations. One is, in an especial manner, the guardian of liberty, and the other, of order. One is the moving power, and the other the steadying power of the state. One is the sail, without which society would make no progress, the other the ballast, without which there would be small safety in a tempest.

Civilizations have always been pyramidal in structure. As one climbs toward the apex of the social edifice, there is increased leisure and increasing opportunity to pursue happiness. As one climbs, one finds also fewer and fewer people to enjoy this more and more. Invariably, there is a preponderance of the dispossessed. And remember this, no matter how well off the bottom layers of the pyramid might be on an absolute scale, they are always dispossessed in comparison with the apex.So there is always social friction in ordinary human societies. The action of social revolution and the reaction of guarding against such revolution or combating it once it has begun are the causes of a great deal of the human misery with which history is permeated.

We are not that we are, nor do we treat or esteem each other for such, but for that we are capable of being.

If I compare arithmetic with a tree that unfolds upward into a multitude of techniques and theorems while its root drives into the depths, then it seems to me that the impetus of the root.

When men and women agree, it is only in their conclusions; their reasons are always different.

And how does the God's existence emerge from the proof? Does it follow straightway, without any breach of continuity? Or have we not here an analogy to the behavior of the little Cartesian dolls? As soon as I let go of the doll it stands on its head. As soon as I let it go, I must therefore let it go. So also with the proof. As long as I keep my hold on the proof, i.e., continue to demonstrate, the existence does not come out, if for no other reason than that I am engaged in proving it; but when I let the proof go, the existence is there. But this act of letting go is surely also something; it is indeed a contribution of mine. Must not this also be taken into the account, this little moment, brief as it may be – it need not be long, for it is a leap. However brief this moment, if only an instantaneous now, this "now" must be included in the reckoning.

The concentration camps, by making death itself anonymous (making it impossible to find out whether a prisoner is dead or alive), robbed death of its meaning as the end of a fulfilled life. In a sense they took away the individual's own death, proving that henceforth nothing belonged to him and he belonged to no one. His death merely set a seal on the fact that he had never existed.

Thus they are deceived by the likeness of blows, and are appeased by the pretended tears of those who deprecate their wrath, and thus an unreal grief is healed by an unreal revenge.

The advantage of meditating upon life and death is being able to say anything at all about them.

Psychotherapists ... are dealing with people whose distress arises from what may be termed maya, to use the Hindu-Buddhist word whose exact meaning is not merely 'illusion' but the entire world-conception of a culture, considered as illusion in the strict etymological sense of a play (Latin, ludere). The aim of a way of liberation is not the destruction of maya but seeing it for what it is, or seeing through it. Play is not to be taken seriously, or, in other words, ideas of the world and of oneself which are social conventions and institutions are not to be confused with reality.

Jean Paul calls the most important night of his life the one when he discovered there was no difference between dying the next day or in thirty years. A revelation as significant as it is futile; if we occasionally manage to grasp its cogency, we resist on the other hand drawing its consequences, in immediacy the difference in question seeming to each of us somehow irreducible, even absolute: to exist is to prove that we have not understood to what point it is all one and the same thing to die now or no matter when.

Lord, you have cursed Cain and Cain's children: thy will be done. You have allowed men's hearts to be corrupted, that their intentions be rotten, that their actions putrefy and stink: thy will be done.

The English, generally remarkable for doing very good things in a very bad manner, seem to have reserved the maturity and plenitude of their awkwardness for the pulpit.

As long as one believes in philosophy, one is healthy; sickness begins when one starts to think.

He who establishes his argument by noise and command shows that his reason is weak.

Love's great (and sole) originality is to make happiness indistinct from misery.

We believe we are rising because while keeping the same base inclinations (for instance: the desire to triumph over others) we have given them a noble object. We should, on the contrary, rise by attaching noble inclinations to lowly objects.

Thus he had a double thought: the one by which he acted as king, the other by which he recognized his true state, and that it was accident alone that had placed him in his present condition.

How absurd it must seem for an immortal soul to be destined for Heaven or Hell, and yet be sitting in a kitchen, as a maid, or to see oneself objectified as a mechanic! how falsely the usual sunrise waked us, the clock dial, the city street the job! How wrongfully people find themselves in these systems - our time isn't there, our space isn't there, our space isn't even here... the whole social story of waking, and certainly the day of the mechanic, is false.

In the army, capitalist development leads to the extension of obligatory military service to the reduction of the time of service and consequently to a material approach to a popular militia. But all of this takes place under the form of modern militarism in which the domination of the people by the militarist State and the class character of the State manifest themselves most clearly.

When shall we see poets born? After a time of disasters and great misfortunes, when harrowed nations begin to breathe again. And then, shaken by the terror of such spectacles, imaginations will paint things entirely strange to those who have not witnessed them.

To be or not to be is not the question where transcendence is concerned. The statement of being's other, of the otherwise than being, claims to state a difference over and beyond that which separates being from nothingness - the very difference of the beyond, the difference of transcendence.

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.

From my youth onwards, I have felt sure that all thought which thinks itself out to an issue ends in mysticism. In the stillness of the African jungle I have been able to work out this thought and give it expression.

Living organisms had existed on earth, without ever knowing why, for over three thousand million years before the truth finally dawned on one of them. His name was Charles Darwin. To be fair, others had had inklings of the truth, but it was Darwin who first put together a coherent and tenable account of why we exist.

In a word, the mass of the people counts for nothing in every political creation. A people even respects a government only because it is not its own creation. This feeling is engraved on its heart in profound characters. It submits to sovereignty because it senses that it is something sacred it can neither create nor destroy. If, as a consequence of corruption and perfidious suggestions, this preventive sentiment is somehow effaced, if it has the misfortune of believing itself called as a body to reform the State, all is lost. This is why, even in free States, it is extremely important that the men who govern be separated from the mass of the people by that personal respect stemming from birth and wealth.

The man of flesh and bone; the man who is born, suffers, and dies-above all, who dies; the man who eats and drinks and plays and sleeps and thinks and wills; the man who is seen and heard; the brother, the real brother.

...the French business is no light or trivial thing, or such as has commonly occurd in the course of political Events. At present the whole political State of Europe hinges upon it. On the Continent there is little doubt; every thing will take is future shape and colour from the good or ill success of the Duke of Brunswick. In my opinion, it is the most important crisis that ever existed in the World. ... My poor opinion is, that these principles...cannot possibly be realized in practice in France, without an absolute certainty and that at no remote period, of overturning the whole fabrick of the British Constitution.

It seems that sin is geographical. From this conclusion, it is only a small step to the further conclusion that the notion of "sin" is illusory, and that the cruelty habitually practised in punishing it is unnecessary.

Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!

Poetry teaches the enormous force of a few words, and, in proportion to the inspiration, checks loquacity.

When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous, and surly. They are like this because they can't tell good from evil. But I have seen the beauty of good, and the ugliness of evil, and have recognized that the wrongdoer has a nature related to my own-not of the same blood or birth, but the same mind, and possessing a share of the divine.

The truth is sum, ergo cogito - I am, therefore I think, although not everything that is thinks. Is not consciousness of thinking above all consciousness of being? Is pure thought possible, without consciousness of self, without personality? Can there exist pure knowledge without feeling, without that species of materiality which feelings lends to it? Do we not perhaps feel thought, and do we not feel ourselves in the act of knowing and willing? Could not the man in the stove [Descartes] have said: "I feel, therefore I am"? or "I will, therefore I am"? And to feel oneself, is it not perhaps to feel oneself imperishable?

He has begun by supposing that light has a constant velocity... the same in all directions. This... could never be verified directly by experiment... The postulate... resembling the principle of sufficient reason... furnishes us with a new rule for the investigation of simultaneity.

There is no belief, however foolish, that will not gather its faithful adherents who will defend it to the death.

The secret of happiness is to face the fact that the world is horrible, horrible, horrible.

Free trade is not based on utility but on justice.

It is true: Man is the microcosm: I am my world.

It has been a long time since philosophers have read men's souls. It is not their task, we are told. Perhaps. But we must not be surprised if they no longer matter much to us.

The political freedom of conscience and of the press, so far from being as it is commonly supposed an extension, is a new case of the limitation of rights and discretion. Conscience and the press ought to be unrestrained, not because men have a right to deviate from the exact line that duty prescribes, but because society, the aggregate of individuals, has no right to assume the prerogative of an infallible judge, and to undertake authoritatively to prescribe to its members in matters of pure speculation.
