We are, I know not how, double in ourselves, which is the cause that what we believe we do not believe, and cannot disengage ourselves from what we condemn.

Tell me what kind of man governs a People, you tell me, with much exactness, what the net sum-total of social worth in that People has for some time been.

Philosophers are adults who persist in asking childish questions. 

So our self-feeling in this world depends entirely on what we back ourselves to be and do.

You can live, provided you live; that is, you can live for ever, provided you live a good life.

A great pilot can sail even when his canvas is rent.

The issue over there being classes seems more a question of convenient conceptual scheme; the issue over there being centaurs, or brick houses on Elm Street, seems more a question of fact. But I have been urging that this difference is only one of degree, and that it turns upon our vaguely pragmatic inclination to adjust one strand of the fabric of science rather than another in accommodating some particular recalcitrant experience. Conservatism figures in such choices, and so does the quest for simplicity.

Whenever the general disposition of the people is such, that each individual regards those only of his interests which are selfish, and does not dwell on, or concern himself for, his share of the general interest, in such a state of things, good government is impossible.

The ancient Egyptians had a superstitious antipathy to the sea; a superstition nearly of the same kind prevails among the Indians; and the Chinese have never excelled in foreign commerce.

If it were so, as conceited sagacity, proud of not being deceived, thinks, that we should believe nothing that we cannot see with our physical eyes, then we first and foremost ought to give up believing in love. ... We can be deceived by believing what is untrue, but we certainly are also deceived by not believing what is true. ... Which deception is more dangerous?

.... In a word, acts of any kind produce habits or characters of the same kind. Hence we ought to make sure that our acts are of a certain kind; for the resulting character varies as they vary. It makes no small difference, therefore, whether a man be trained in his youth up in this way or that, but a great difference, or rather all the difference.

To one that promised to give him hardy cocks that would die fighting, "Prithee," said Cleomenes, "give me cocks that will kill fighting."

Nevertheless, the ultimate business of philosophy is to preserve the force of the most elemental words in which Dasein expresses itself, and to keep the common understanding from levelling them off to that unintelligibility which functions in turn as a source of pseudo-problems.

On the death of a friend, we should consider that the fates through confidence have devolved on us the task of a double living, that we have henceforth to fulfill the promise of our friend's life also, in our own, to the world.

I believe in Christianity as I believe that the sun has risen. Not only because I see it, but because by it I see everything else.

When people begin to philosophize they seem to think it necessary to make themselves artificially stupid.

There is nothing but violence in the universe; but we are spoiled by a modern philosophy that tells us all is good, whereas evil has tainted everything, and in a very real sense, all is evil, since nothing is in its place.

But if judicious men skilled in Chymical affairs shall once agree to write clearly and plainly of them, and thereby keep men from being stunn'd... or imposed upon by dark and empty Words; 'tis to be hop'd that these men finding that they can no longer write impertinently and absurdly, without being laugh'd at for doing so, will be reduc'd either to write nothing, or Books that may teach us something, and not rob men, as formerly, of invaluable Time; and so ceasing to trouble the world with Riddles or Impertinencies, we shall either by their Books receive an Advantage, or by their silence escape an Inconvenience.

Go where he will, the wise man is at home, His hearth the earth, his hall the azure dome.

The Path is not far from man. When men try to pursue a course, which is far from the common indications of consciousness, this course cannot be considered The Path.

Editor Preface In this book, originating in the year 1848, the requirement for being a Christian is forced up by the pseudonymous author to the supreme ideality. Yet the requirement should indeed be stated, presented, and heard. From the Christian point of view, there ought to be no scaling down of the requirement, nor suppression of it-instead of a personal admission and confession. The requirement should be heard-and I understand what is said as spoken to me alone-so that I might learn not only to resort to grace but to resort to it in relation to the use of grace.

Every oasis is an island that has water inside it but not round it.

Having given up autonomy, reason has become an instrument.

If the individual were no longer compelled to prove himself on the market, as a free economic subject, the disappearance of this kind of freedom would be one of the greatest achievements of civilization. The technological processes of mechanization and standardization might release individual energy into a yet uncharted realm of freedom beyond necessity. The very structure of human existence would be altered; the individual would be liberated from the work world's imposing upon him alien needs and alien possibilities. The individual would be free to exert autonomy over a life that would be his own.

But in life, as we are cognizant of it, mental development can go but a little way. The mind hardly begins to awake ere the bodily powers decline - it but becomes dimly conscious of the vast fields before it, but begins to learn and use its strength, to recognize relations and extend its sympathies, when, with the death of the body, it passes away. Unless there is something more, there seems here a break, a failure. Whether it be a Humboldt or a Herschel, a Moses who looks from Pisgah, a Joshua who leads the host, or one of those sweet and patient souls who in narrow circles live radiant lives, there seems, if mind and character here developed can go no further, a purposelessness inconsistent with what we can see of the linked sequence of the universe.

As there is a use in medicine for poisons, so the world cannot move without rogues.

What froze me was the fact that I had absolutely no reason to move in any direction. What had made me move through so many dead and pointless years was curiosity. Now even that flickered out.

Men remain in their present low and primitive condition; but if they should feel the influence of the spring of springs arousing them, they would of necessity rise to a higher and more ethereal life.

The antithesis of 'Sense' & 'Ideas' is the foundation of the Philosophy of Science. No knowledge can exist without the union, no philosophy without the separation, of these two elements.

When an acquaintance goes by I often step back from my window, not so much to spare him the effort of acknowledging me as to spare myself the embarrassment of seeing that he has not done so.

To speak ill of others is a dishonest way of praising ourselves; let us be above such transparent egotism. If you can't say good and encouraging things, say nothing. Nothing is often a good thing to do, and always a clever thing to say.

Man is a reasoning animal.

The difference between the artificial and the artful in the artistic lies on the surface in the former there is a split between what is overly done and what is intended. The appearance is one of cordiality; the intent is that of gaining favor. Whenever this split between what is done and its purpose exists, there is insincerity, a trick, a simulation of an act that intrinsically has another effect. When the natural and the cultivated blend into one, acts of social intercourse are works of art. The animating impulsion of genial friendship and the deed performed completely coincide without intrusion of ulterior motive. Awkwardness may prevent adequacy of expression.

A special kind of beauty exists which is born in language, of language, and for language.

For this too is a very pleasant strand woven into the Cynic's pattern of life; he must needs be flogged like an ass, and while he is being flogged he must love the men who flog him, as though he were the father or brother of them all.

It is certain that nature inclines us toward the amorous orgy, just as much as toward the gastronomic orgy, and that while both are blameworthy in the excess, they would become praiseworthy in an order in which they could be equilibrated.

I prefer to reach the few who really want to learn, rather than the many who come to be amused.

The objects of a financier are, then, to secure an ample revenue; to impose it with judgment and equality; to employ it economically; and, when necessity obliges him to make use of credit, to secure its foundations in that instance, and for ever, by the clearness and candour of his proceedings, the exactness of his calculations, and the solidity of his funds.

The young men were born with knives in their brain, a tendency to introversion, self-dissection, anatomizing of motives.

What is left when honor is lost?

I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell them: "This fellow isn't insane. We are only doing philosophy."

It is almost everywhere the case that soon after it is begotten the greater part of human wisdom is laid to rest in repositories.

Here was buried Thomas Jefferson, author of the Declaration of American Independence, of the Statute of Virginia for Religious Freedom, and Father of the University of Virginia. Epitaph, upon his instructions to erect a "a plain die or cube ... surmounted by an Obelisk" with "the following inscription, and not a word more...because by these, as testimonials that I have lived, I wish most to be remembered." It omits that he had been President of the United States, a position of political power and prestige, and celebrates his involvement in the creation of the means of inspiration and instruction by which many human lives have been liberated from oppression and ignorance.

Descartes may have made a lot of mistakes, but he was right about this: you cannot doubt the existence of your own consciousness. That's the first feature of consciousness, it's real and irreducible. You cannot get rid of it by showing that it's an illusion in a way that you can with other standard illusions.
