The great end of life is not knowledge but action.

Men who undertake considerable things, even in a regular way, ought to give us ground to presume ability.

At root what is needed for scientific inquiry is just receptivity to data, skill in reasoning, and yearning for truth. Admittedly, ingenuity can help too.

The guidelines for achieving wisdom consist of three leading maxims: 1) Think for yourself; 2) (in communication with other people) Put yourself in the place of the other person; 3) Always think by remaining faithful to your own self.

We cannot pretend that we do not see the armed policeman who marches up and down beneath our window to guarantee our security while we eat our luxurious dinner, or look at the new piece at the theater, or that we are unaware of the existence of the soldiers who will make their appearance with guns and cartridges directly our property is attacked.

Born for success he seemed, With grace to win, with heart to hold, With shining gifts that took all eyes.

First then, we find that when we regard ideas from a nominalistic, individualistic, sensualistic way, the simplest facts of mind become utterly meaningless. That one idea should resemble another or influence another, or that one state of mind should so much as be thought of in another is, from that standpoint, sheer nonsense.

It has been said a thousand times and in a thousand books that ancestor-worship is for the most part the source of primitive religions, and it may be strictly said that what most distinguishes man from the other animals is that, in one form or another, he guards his dead and does not give them over to the neglect of teeming mother earth; he is an animal that guards its dead.

To have good sense, is the first principle and fountain of writing well.

Great men, great nations, have not been boasters and buffoons, but perceivers of the terror of life, and have manned themselves to face it.

If we compare the third-person attitude of someone who simply says how things stand (this is the attitude of the scientist, for example) with the performative attitude of someone who tries to understand what is said to him (this is the attitude of the interpreter, for example), the implications ... become clear. ... First, interpreters relinquish superiority that observers have by virtue of their privileged position, in that they themselves are drawn, at least potentially, into negotiations about the meaning and validity of utterances. By taking part in communicative action, they accept in principle the same status as those whose utterances they are trying to understand. ... It is impossible to decide a priori who is to learn from whom.

For his purposes (and mine), scientific medicine is defined as the set of practices which submit themselves to the ordeal of being tested. Alternative medicine is defined as that set of practices which cannot be tested, refuse to be tested, or consistently fail tests. If a healing technique is demonstrated to have curative properties in properly controlled double-blind trials, it ceases to be alternative. It simply, as Diamond explains, becomes medicine. Conversely, if a technique devised by the President of the Royal College of Physicians consistently fails in double-blind trials, it will cease to be a part of 'orthodox' medicine. Whether it will then become 'alternative' will depend upon whether it is adopted by a sufficiently ambitious quack (there are always sufficiently gullible patients).

The invention and spread of contraceptives is the proximate cause of our changing morals. The old moral code restricted sexual experience to marriage, because copulation could not be effectively separated from parentage, and parentage could be made responsible only through marriage. But to-day the dissociation of sex from reproduction has created a situation unforeseen by our fathers. All the relations of men and women are being changed by this one factor; and the moral code of the future will have to take account of these new facilities which invention has placed at the service of ancient desires.

Saint-Simon, like Hegel, begins with the assertion that the social order engendered by the French Revolution proved that mankind has reached the adult state. In contrast to Hegel, however, he described this stage primarily in terms of its economy; the industrial process was the sole integrating factor in the new social order.

The only progress I can see is progress in the organization. The ordinary human being does not live long enough to draw any substantial benefit from his own experience. And no one, it seems, can benefit by the experiences of others. Being both a father and teacher, I know we can teach our children nothing. We can transmit to them neither our knowledge of life nor of mathematics. Each must learn its lesson anew.

To none is life given in freehold; to all on lease.

No realistic, sane person goes around Chicago without protection.

Here and there it happened in my practice that a patient grew beyond himself because of unknown potentialities, and this became an experience of prime importance to me. I had learned in the meanwhile that the greatest and most important problems of life are all in a certain sense insoluble. They must be so because they express the necessary polarity inherent in every self-regulating system. They can never be solved, but only outgrown.

A brilliant man is his own best company, unless he can find other company of the same sort.

In the pedagogical as in certain other spheres freedom is not allowed to erupt, the power of the opposition is not allowed to put a word in edgewise: they want submissiveness. Only a formal and material training is being aimed at and only scholars come out of the menageries of the humanists, only "useful citizens" out of those of the realists, both of whom are indeed nothing but subservient people. Our good background of recalcitrancy [sic] gets strongly suppressed and with it the development of knowledge to free will. The result of school is then philistinism.

Men will always be mad, and those who think they can cure them are the maddest of all.

History is mere Empiricism; it has only facts to communicate, and all its proofs are founded upon facts alone. To attempt to rise to Primeval History on this foundation of fact, or to argue by this means how such or such a thing might have been, and then to take for granted that it has been so in reality,is to stray beyond the limits of History, and produce an a priori History; just as the Philosophy of Nature, referred to in our preceding lecture, endeavoured to find an a priori Science of Physics.

Morality is thus the relation of actions to the autonomy of the will, that is, to a possible giving of universal law through its maxims. An action that can coexist with the autonomy of the will is permitted; one that does not accord with it is forbidden. A will whose maxims necessarily harmonize with the laws of autonomy is a holy, absolutely good will. The dependence upon the principle of autonomy of a will that is not absolutely good (moral necessitation) is obligation. This, accordingly, cannot be attributed to a holy being. The objective of an action from obligation is called duty.

Freedom of thought and of expression are not mere rights to be claimed. They have their roots deep in the existence of individuals as developing careers in time. Their denial and abrogation is an abdication of individuality and a virtual rejection of time as opportunity.

It has become almost a cliché to remark that nobody boasts of ignorance of literature, but it is socially acceptable to boast ignorance of science and proudly claim incompetence in mathematics.

The way you use the word "God" does not show whom you mean - but, rather, what you mean.

Our age is retrospective. It builds the sepulchres of the fathers. It writes biographies, histories, and criticism. The foregoing generation beheld God and nature face to face; we, through their eyes. Why should not we also enjoy an original relation to the universe. Why should not we have a poetry and philosophy of insight and not of tradition, and a religion by revelation to us, and not the history of theirs?

Religious minds, which are distrustful of philosophic dogmas, fall into the error - inculcated by philosophy - of supposing that Providence is limited in its action; that is does not extend to the social world or the social relations of mankind, and that God has not determined upon any plan of social organization for the regulation of those relations. If they had a PROFOUND FAITH IN THE UNIVERSALITY OF PROVIDENCE, they would be convinced that all human needs must have been foreseen and provided for, and especially that the most urgent of them all could not have been overlooked - namely, the need of a social order for the regulation of our industrial and social relations.

Only when the true ends of society have nothing to do with the sublime does "culture" become necessary as a veneer to cover over the void. Culture can at best appreciate the monuments of earlier faith; it cannot produce them.

The phaenomena afforded by trades, are a part of the history of nature, and therefore may both challenge the naturalist's curiosity and add to his knowledge, Nor will it suffice to justify learned men in the neglect and contempt of this part of natural history, that the men, from whom it must be learned, are illiterate mechanicks... is indeed childish, and too unworthy of a philosopher, to be worthy of an honest answer.

What makes our poetry so contemptible nowadays is its paucity of ideas. If you want to be read, invent. Who the Devil wouldn't like to read something new?

Perhaps the promise of phallus is always dissatisfying in some way.

If conquest constitutes a natural right on the part of the few, the many have only to gather sufficient strength in order to acquire the natural right of reconquering what has been taken from them.

The refined and active, on the other hand, prefer honour, which I suppose may be said to be the end of the political life. Yet honour is plainly too superficial to be the object of our search, because it appears to depend rather on those who give than on those who receive it, whereas we feel instinctively that the good must be something proper to a man, which cannot easily be taken from him.

Education is the instruction of the intellect in the laws of Nature, under which name I include not merely things and their forces, but men and their ways; and the fashioning of the affections and of the will into an earnest and loving desire to move in harmony with those laws. For me, education means neither more nor less than this. Anything which professes to call itself education must be tried by this standard, and if it fails to stand the test, I will not call it education, whatever may be the force of authority, or of numbers, upon the other side.

I disclose my mysteries to those who are worthy of my mysteries.

No production without a need. But consumption reproduces the need.

The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, scepticism is the highest of duties; blind faith the one unpardonable sin. And it cannot be otherwise, for every great advance in natural knowledge has involved the absolute rejection of authority, the cherishing of the keenest scepticism, the annihilation of the spirit of blind faith; and the most ardent votary of science holds his firmest convictions, not because the men he most venerates hold them; not because their verity is testified by portents and wonders; but because his experience teaches him that whenever he chooses to bring these convictions into contact with their primary source, Nature - whenever he thinks fit to test them by appealing to experiment and to observation - Nature will confirm them. The man of science has learned to believe in justification, not by faith, but by verification. On the advisableness of improving natural knowledge

The election... on November 3 ... illustrates a lot of these clashing forces. ..That election was the most important political fight ...in my lifetime. It's important not just for the United States but... for the rest of the world, given the role that the United States has historically played in maintaining that broader liberal international order.

The words of malicious slander should not be allowed to enter the ear. A defensive voice should not be allowed to come out of the mouth. The want to gravely injure people should not be allowed to exist in the heart. If this is accomplished, though there be people who cynically expose others, they would be without people who would align with them.

Pantheism makes God into a present, real, and material being; empiricism - to which rationalism also belongs - makes God into an absent, remote, unreal, and negative being. Empiricism does not deny God existence, but denies him all positive determinations, because their content is supposed to be only finite and empirical; the infinite cannot, therefore, be an object for man. But the more determinations I deny to a being, the more do I cut it of[ from myself, and the less power and influence do I concede to it over me, the freer do I make myself of it. The more qualities I possess, the more I am for others, and the greater is the extent of my influence and effects. And the more one is, the more one is known to others. Hence, each negation of an attribute of God is a partial atheism, a sphere of godlessness.

Take heed lest any man deceive you: For many shall come in my name, saying, I am Christ; and shall deceive many. And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows. But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. And the gospel must first be published among all nations. But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost.

The journey of a thousand miles begins with a single step.

Communism was not the crazy fantasy of a few fanatics, nor the result of human stupidity and baseness; it was a real, very real part of the history of the twentieth century, and we cannot understand this history of ours without understanding communism. We cannot get rid of this specter by saying it was just "human stupidity," or "human corruptibility." The specter is stronger than the spells we cast on it. It might come back to life.

A man who chooses between drinking a glass of milk and a glass of a solution of potassium cyanide does not choose between two beverages; he chooses between life and death. A society that chooses between capitalism and socialism does not choose between two social systems; it chooses between social cooperation and the disintegration of society. Socialism is not an alternative to capitalism; it is an alternative to any system under which men can live as human beings.

I don't believe in an afterlife, so I don't have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse.
