On another possible world or another planet a word might be associated with much the same stereotype and much the same criteria as our term 'water', but it might designate XYZ and not H₂O. At least this could happen in a prescientific era. And it would not follow that XYZ was water; it would only follow that XYZ could look like water, taste like water, etc. What 'water' refers to depends on the actual nature of the paradigms, not just on what is in our heads.

And if he be too forward to venture upon his own strength and skill, and perplexity and trouble of a misadventure now and then, that reaches not his innocence, his health, or reputation, may not be an ill way to teach him more caution.

Good music is very close to primitive language.

No epoch is homogeneous; whatever you may have assigned as the dominant note of a considerable period, it will always be possible to produce men, and great men, belonging to the same time, who exhibit themselves as antagonistic to the tone of their age.

In the face of the idea that truth might afford the opposite of satisfaction and turn out to be completely shocking to humanity at any given historical moment, ... the fathers of pragmatism made the satisfaction of the subject the criterion of truth. For such a doctrine there is no possibility of rejecting or even criticizing any species of belief that is enjoyed by its adherents.

Art can speak its own language only as long as the images are alive which refuse and refute the established order.

To study and not think is a waste. To think and not study is dangerous. Learning without thought is labor lost; thought without learning is perilous.

History is a story without an end.

So in this idea, then, everybody is fundamentally the ultimate reality. Not God in a politically kingly sense, but God in the sense of being the self, the deep-down basic whatever there is. And you're all that, only you're pretending you're not. And it's perfectly OK to pretend you're not, to be perfectly convinced, because this is the whole notion of drama.

Trying to define yourself is like trying to bite your own teeth.

The novel, the novel proper that is, is about people's treatment of each other, and so it is about human values.

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 opinions that are held with passion are always those for which no good ground exists; indeed the passion is the measure of the holder's lack of rational conviction.

Erosion of our being by our infirmities: the resulting void is filled by the presence of consciousness, what am I saying? - that void is consciousness itself.

The endeavor of scientific research to see events in their more general connection in order to determine their laws, is a legitimate and useful occupation. Any protest against such efforts, in the name of freefom from restrictive conditions, would be fruitless if science did not naïvely identify the abstractions called rules and laws with the actually efficacious forces, and confuse the probability that B will follow A with the actual effort make B follow A.

Love is something more stern and splendid than mere kindness.

There is no penalty attached to a lover's oath.

We have learned to tolerate the facts of war: that men are killed en masse - some twenty million in the Second World War - that whole cities and their inhabitants are annihilated by the atomic bomb, that men are turned into living torches by incendiary bombs. We learn of these things from the radio or newspapers and we judge them according to whether they signify success for the group of peoples to which we belong, or for our enemies. When we do admit to ourselves that such acts are the results of inhuman conduct, our admission is accompanied by the thought that the very fact of war itself leaves us no option but to accept them. In resigning ourselves to our fate without a struggle, we are guilty of inhumanity.

Frugality is founded on the principle that all riches have limits.

Yes, truly, it is a great thing for a Nation that it get an articulate voice; that it produce a man who will speak forth melodiously what the heart of it means!

The problems are dissolved in the actual sense of the word - like a lump of sugar in water.

When people were committed to the idea that in the field of religion only one plan must be adopted, bloody wars resulted. With the acknowledgment of the principle of religious freedom these wars ceased. The market economy safeguards peaceful economic co-operation because it does not use force upon the economic plans of the citizens. If one master plan is to be substituted for the plans of each citizen, endless fighting must emerge. Those who disagree with the dictator's plan have no other means to carry on than to defeat the despot by force of arms.

...all of the philosophers put together are not worth a single saint.

The emotions I feel are no more meant to be shown in their unadulterated state than the inner organs by which we live.

What is obscene about pornography is not an excess of sex, but the fact that it contains no sex at all.

One need only open the eyes to see that the conquests of industry which have enriched so many practical men would never have seen the light, if these practical men alone had existed and if they had not been preceded by unselfish devotees who died poor, who never thought of utility, and yet had a guide far other than caprice.As Mach says, these devotees have spared their successors the trouble of thinking.

Impossible to accede to truth by opinions, for each opinion is only a mad perspective of reality.

All men by nature desire to know. An indication of this is the delight we take in our senses; for even apart from their usefulness they are loved for themselves; and above all others the sense of sight. For not only with a view to action, but even when we are not going to do anything, we prefer sight to almost everything else. The reason is that this, most of all the senses, makes us know and brings to light many differences between things.

Well, then, arrest him. You can accuse him of something or other afterward.

Distinctive signs, full signs, never seduce us.

Therefore, my dear Lucilius, begin at once to live, and count each separate day as a separate life.

The first act of violence that patriarchy demands of males is not violence toward women. Instead patriarchy demands of all males that they engage in acts of psychic self-mutilation, that they kill off the emotional parts of themselves. If an individual is not successful in emotionally crippling himself, he can count on patriarchal men to enact rituals of power that will assault his self-esteem.

Setting the mind to remember... involves a continual minimal irradiation of excitement into paths which lead thereto... the continued presence of the thing in the 'fringe' of our consciousness. Letting the thing go involves withdrawal of the irradiation, unconsciousness of the thing, and... obliteration of the paths.

If a man makes the press utter atrocious things he becomes as answerable for them as if he had uttered them by word of mouth. Mr. Jefferson has said in his inaugural speech, that "error of opinion might be tolerated, when reason was left free to combat it." This is sound philosophy in cases of error. But there is a difference between error and licentiousness.

The infinite... happens to subsist in a way contrary to what is asserted by others: for the infinite is not that beyond which there is nothing, but it is that of which there is always something beyond. ...But that pertaining to which there is nothing beyond is perfect and whole. ...that of which nothing is absent pertaining to the parts ...the whole is that pertaining to which there is nothing beyond. But that pertaining to which something external is absent, that is not all ...But nothing is perfect which has not an end; and the end is a bound. On this account... Parmenides spoke better than Melissus: for the latter says that the infinite is a whole; but the former, that the whole is finite, and equally balanced from the middle: for to conjoin the infinite with the universe and the whole, is not to connect line with line.

To one who asked what was the proper time for lunch, he said, "If a rich man, when you will; if a poor man, when you can."

Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?

Solicitation and effort or conation belong properly to animate beings alone. When they are attributed to other things, they must be taken in a metaphorical sense; but a philosopher should abstain from metaphor.

One should never direct people towards happiness, because happiness too is an idol of the market-place. One should direct them towards mutual affection. A beast gnawing at its prey can be happy too, but only human beings can feel affection for each other, and this is the highest achievement they can aspire to.

He that has a secret should not only hide it, but hide that he has it to hide.

Let any one try, I will not say to arrest, but to notice or attend to, the present moment of time. One of the most baffling experiences occurs. Where is it, this present? It has melted in our grasp, fled ere we could touch it, gone in the instant of becoming.

Men rush to California and Australia as if the true gold were to be found in that direction; but that is to go to the very opposite extreme to where it lies. They go prospecting farther and farther away from the true lead, and are most unfortunate when they think themselves most successful.

By 1204, the only place where the entire body of Greek learning existed, still intact, was Constantinople. As a result of the crusaders' conquest, however, Constantinople was ruthlessly pillaged and destroyed and almost all the great treasures of ancient Greek learning were lost forever. It is because of that sack, for instance, that we have only seven plays left out of the better than one hundred written by Sophocles. The tragedy of 1204 can never be undone and for all of time, only bits and pieces of the marvelous Greek world can be known to us.

Don't tell yourself anything more than what the initial impressions report. It's been reported to you that someone is speaking badly about you. This is the report - the report wasn't that you've been harmed. I see that my son is sick - but not that his life is at risk. So always stay within your first impressions, and don't add to them in your head - this way nothing can happen to you.

The world is in an extremely dangerous situation, and serious diseases often require the risk of a dangerous cure - like the Pasteur serum for rabies.

Man is something that is to be overcome.Logically considered, this, too, presents a contradiction: he who overcomes himself is admittedly the victor, but he is also the defeated. The ego succumbs to itself, when it wins; it achieves victory, when it suffers defeat. Yet the contradiction only arises when the two aspects of this unity are hardened into opposed, mutually exclusive conceptions. It is precisely the fully unified process of the moral life which overcomes and surpasses every lower state by achieving a higher one, and again transcends this latter state through one still higher. That man overcomes himself means that he reaches out beyond the bounds that the moment sets for him. There must be something at hand to be overcome, but it is only there in order to be overcome. Thus even as an ethical agent, man is the limited being that has no limit.

There is another ground of hope that must not be omitted. Let men but think over their infinite expenditure of understanding, time, and means on matters and pursuits of far less use and value; whereof, if but a small part were directed to sound and solid studies, there is no difficulty that might not be overcome.

Faith looks to the word and the promise; that is, to the truth. But hope looks to that which the word has promised, to the gift.

It must be said that charity can, in no way, exist along with mortal sin.
