It is sometimes maintained that racial mixture is biologically undesirable. There is no evidence whatever for this view. Nor is there, apparently, any reason to think that Negroes are congenitally less intelligent than white people, but as to that it will be difficult to judge until they have equal scope and equally good social conditions.

A Muslim who knows French will never be a dangerous Muslim.

[On members of the Nazi Party] The most shocking, but also important thing, is they were not the uneducated masses. The majority had academic degrees. We like to think that education provides immunity to racist and fascist ideology. And it doesn't.

While they denounce as subversive anarchy signs of independent thought, of thinking for themselves on the part of others lest such thought disturb the conditions by which they profit, they think quite literally for themselves, that is of themselves.

It is truly a marvelous thing to consider to what greatness Athens arrived in the space of one hundred years after she freed herself from the tyranny of Pisistratus; but, above all, it is even more marvelous to consider the greatness Rome reached when she freed herself from her kings. The reason is easy to understand, for it is the common good and not private gain that makes cities great. Yet, without a doubt, this common good is observed only in republics, for in them everything that promotes it is practised, and however much damage it does to this or that private individual, those who benefit from the said common good are so numerous that they are able to advance in spite of the inclination of the few citizens who are oppressed by it.

"Freedom" awakens your rage against everything that is not you; "egoism" calls you to joy over yourselves, to self-enjoyment.

Love with delight discourses in my mind Upon my lady's admirable gifts...Beyond the range of human intellect.

The Scientific discourse extracts truths from the errors which surround and oppose it on all sides and in every form; and, by demolition of these opposing views as error, and as impossible to true thought, shows the truth as that which alone remains after their withdrawal, and therefore as the only possible truth:--and in this separation of opposites, and elucidation of the truth from the confused chaos in which truth and error lie mingled together, consists the peculiar and characteristic nature of the Scientific discourse. This method creates and produces truth, before our eyes, out of a world full of error.

Money is coined liberty, and so it is ten times dearer to the man who is deprived of freedom. If money is jingling in his pocket, he is half consoled, even though he cannot spend it. But money can always and everywhere be spent, and, moreover, forbidden fruit is sweetest of all.

Our plans miscarry because they have no aim. When a man does not know what harbour he is making for, no wind is the right wind.

Resolved to die in the last dike of prevarication.

It is life that educates, and perhaps love more than anything else in life.

The difference between a pessimistic and an optimistic mind is of such controlling importance in regard to every intellectual function, and especially for the conduct of life, that it is out of the question to admit that both are normal, and the great majority of mankind are naturally optimistic.

The living force of his soul gained the day: on he passed far beyond the flaming walls of the world and traversed throughout in mind and spirit the immeasurable universe.

This market way of life promotes addictions to stimulation and obsessions with comfort and convenience.

Be your money's master, not its slave.

Metaphysical rebellion is a claim, motivated by the concept of a complete unity, against the suffering of life and death and a protest against the human condition both for its incompleteness, thanks to death, and its wastefulness, thanks to evil.

No human acquisition is stable. Even what appears to us most completely won and consolidated can disappear in a few generations. This thing we call "civilization" - all these physical and moral comforts, all these conveniences, all these shelters, all these virtues and disciplines which have become habit now, on which we count, and which in effect constitute a repertory or system of securities which man made for himself like a raft in the initial shipwreck which living always is - all these securities are insecure securities which in the twinkling of an eye, at the least carelessness, escape from man's hands and vanish like phantoms.

The political is the most intense and extreme antagonism, and every concrete antagonism becomes that much more political the closer it approaches the most extreme point, that of the friend-enemy grouping.

There was a brief moment after 9/11 when Colin Powell said "we should not rush to satisfy the desire for revenge." It was a great moment, an extraordinary moment, because what he was actually asking people to do was to stay with a sense of grief, mournfulness, and vulnerability.

From Richard McKeon and Robert Brumsbaugh I learned to view the history of philosophy as a series, not of alternative solutions to the same problems, but of quite different sets of problems. From Rudolph Carnap and Carl Hempel I learned how pseudo-problems could be revealed as such by restarting them in the formal mode of speech. From Charles Hartshorne and Paul Weiss I learned how they could be so revealed by being translated into Whiteheadian or Hegelian terms.

I have tried to set forth a theory that enables us to understand and to assess these feelings about the primacy of justice. Justice as fairness is the outcome: it articulates these opinions and supports their general tendency.

Look now, this is the starting point of philosophy: the recognition that different people have conflicting opinions, the rejection of mere opinion so that it comes to be viewed with mistrust, an investigation of opinion to determine whether it is rightly held, and the discovery of a standard of judgement, comparable to the balance that we have devised for the determining of weights, or the carpenter's rule for determining whether things are straight or crooked.

I am quite convinced; and, believe me, if I were again beginning my studies, I should follow the advice of Plato and start with mathematics, a science which proceeds very cautiously and admits nothing as established until it has been rigidly demonstrated.

The great work of the present for every man, and every organization of men, who would improve social conditions, is the work of education - the propagation of ideas. It is only as it aids this that anything else can avail. And in this work every one who can think may aid - first by forming clear ideas himself, and then by endeavoring to arouse the thought of those with whom he comes in contact.

The proximity between the counterfeit and the good coin does not make the good coin counterfeit nor the counterfeit good. In the same way the proximity between truth and falsehood does not make truth falsehood nor falsehood truth.

A rolling stone gathers no moss.

The role of philosophy might be said to be to extend and deepen the self-awareness of mankind.

Yes, I am so free. And what a superb absence is my soul.

Every innovation scraps its immediate predecessor and retrieves still older figures - it causes floods of antiques or nostalgic art forms and stimulates the search for museum pieces.

We do not obtain the most precious gifts by going in search of them but by waiting for them. Man cannot discover them by his own powers, and if he sets out to seek for them he will find in their place counterfeits of which he will be unable to discern falsity.

If all else fails, the character of a man can be recognized by nothing so surely as by a jest which he takes badly. 

Skepticism is an exercise in defascination.

"A man thinks he is dying for his country," said Anatole France, "but he is dying for a few industrialists." But even that is saying too much. What one dies for is not even so substantial and tangible as an industrialist.

The noblest people are those despising wealth, learning, pleasure and life; esteeming above them poverty, ignorance, hardship and death.

The militarily-patriotic and the romantic-minded everywhere, and especially the professional military class, refuse to admit for a moment that war may be a transitory phenomenon in social evolution. The notion of a sheep's paradise like that revolts, they say, our higher imagination. Where then would be the steeps of life? If war had ever stopped, we should have to re-invent it, on this view, to redeem life from flat degeneration. Reflective apologists for war at the present day all take it religiously. It is a sort of sacrament. It's profits are to the vanquished as well as to the victor; and quite apart from any question of profit, it is an absolute good, we are told, for it is human nature at its highest dynamic.

Our questions and answers are in part determined by the historical tradition in which we find ourselves. We apprehend truth from our own source within the historical tradition. The content of our truth depends upon our appropriating the historical foundation. Our own power of generation lies in the rebirth of what has been handed down to us. If we do not wish to slip back, nothing must be forgotten; but if philosophising is to be genuine our thoughts must arise from our own source. Hence all appropriation of tradition proceeds from the intentness of our own life. The more determinedly I exist, as myself, within the conditions of the time, the more clearly I shall hear the language of the past, the nearer I shall feel the glow of its life.

If the love of money is the root of all evil, the need of money is most certainly the root of all despair.

As geological time goes, it is but a moment since the human race began and only the twinkling of an eye since the arts of civilization were first invented. In spite of some alarmists, it is hardly likely that our species will completely exterminate itself. And so long as man continues to exist, we may be pretty sure that, whatever he may suffer for a time, and whatever brightness may be eclipsed, he will emerge sooner or later, perhaps strengthened and reinvigorated by a period of mental sleep. The universe is vast and men are but tiny specks on an insignificant planet. But the more we realize our minuteness and our impotence in the face of cosmic forces, the more astonishing becomes what human beings have achieved.

In England women are still occasionally used instead of horses for hauling canal boats, because the labour required to produce horses and machines is an accurately known quantity, while that required to maintain the women of the surplus population is below all calculation.

Physiology does not teach us how to digest, nor logic how to discourse, nor esthetics how to feel beauty or express it, nor ethics how to be good. And indeed it is well if they do not teach us how to be hypocrites; for pedantry, whether it be pedantry of logic, or of esthetics, or of ethics, is at bottom nothing but hypocrisy.

Patriotism ruins history.
