The philosophical thought of Kant, the supreme flower of the Germanic people, has its roots in the religious feeling of Luther, and it is not possible for Kantism, especially the practical part of it, to take root and bring forth flower and fruit in peoples who have not undergone the experience of the Reformation and who perhaps were incapable of experiencing it. Kantism is Protestant, and we Spaniards are fundamentally Catholic. And if Krause struck some roots here - more numerous and more permanent than is commonly supposed - it is because Krause has roots in pietism, and pietism, as Ritschl has demonstrated in his Geschichte des Pietismus, has specifically Catholic roots and may be described as the irruption, or rather the persistence of Catholic mysticism in the heart of Protestant rationalism. And this explains why not a few Catholic thinkers in Spain became followers of Krause.

It is provable both that the historical sequence was, in its main outlines, a necessary one; and that the causes which determined it apply to the child as to the race. ...as the mind of humanity placed in the midst of phenomena and striving to comprehend them has, after endless comparisons, speculations, experiments, and theories, reached its present knowledge of each subject by a specific route; it may rationally be inferred that the relationship between mind and phenomena is such as to prevent this knowledge from being reached by any other route; and that as each child's mind stands in this same relationship to phenomena, they can be accessible to it only through the same route. Hence in deciding upon the right method of education, an inquiry into the method of civilization will help to guide us.

Nietzsche ... did not settle for a demure civic conversation in the style of Richard Rorty's ironist, or saunter off with the smug nod that registers a deconstructive job neatly done. He was aware that his own criticisms and exposures owed both their motivation and their effect to the spirit of truthfulness. His aim was to see how far the values of truth could be revalued, how they might be understood in a perspective quite different from the Platonic and Christian metaphysics which had provided their principal source in the West up to now.

The blues is relevant today because when we look down through the corridors of time, the black American interpretation of tragicomic hope in the face of dehumanizing hate and oppression will be seen as the only kind of hope that has any kind of maturity in a world of overwhelming barbarity and bestiality. That barbarity is found not just in the form of terrorism but in the form of the emptiness of our lives - in terms of the wasted human potential that we see around the world. In this sense, the blues is a great democratic contribution of black people to world history.

To be an intellectual really means to speak a truth that allows suffering to speak. That is, it creates a vision of the world that puts into the limelight the social misery that is usually hidden or concealed by the dominant viewpoints of a society. "Intellectual" in that sense simply means those who are willing to reflect critically upon themselves as well as upon the larger society and to ascertain whether there is some possibility of amelioration and betterment.

These preachers of beauty, which light the world with their admonishing smile.

He that dies in extreme old age will be reduced to the same state with him that is cut down untimely.

Or, if you enjoy living with Greeks also, spend your time with Socrates and with Zeno: the former will show you how to die if it be necessary; the latter how to die before it is necessary. Live with Chrysippus, with Posidonius: they will make you acquainted with things earthly and things heavenly; they will bid you work hard over something more than neat turns of language and phrases mouthed forth for the entertainment of listeners; they will bid you be stout of heart and rise superior to threats. The only harbour safe from the seething storms of this life is scorn of the future, a firm stand, a readiness to receive Fortune's missiles full in the breast, neither skulking nor turning the back.

The stronghold of the determinist argument is the antipathy to the idea of chance...This notion of alternative possibility, this admission that any one of several things may come to pass is, after all, only a roundabout name for chance.

In the Church which was founded at Corinth, St. Paul had special difficulties of the kind I have mentioned. In that flourishing commercial city, which through its shipping and situation, maintained a vital connexion between East and West, numerous crowds of people flocked together from all quarters, different in speech and in culture. As they mingled with the inhabitants, they produced, by contacts and contrasts, new and ever new differences. Even in the Church this differentiation endeavoured to make itself felt in sects and parties; and a kind of pagan wisdom made a special attempt to force itself forward as a teacher of truth. In his first letter to this church, from which the text I read is taken, St. Paul strongly combats this tendency.

The fact that the general incidence of leukemia has doubled in the last two decades may be due, partly, to the increasing use of x-rays for numerous purposes. The incidence of leukemia in doctors, who are likely to be so exposed, is twice that of the general public. In radiologists the incidence is ten times greater.

And because it may be too great a temptation to human frailty, apt to grasp at power, for the same persons, who have the power of making laws, to have also in their hands the power to execute them, whereby they may exempt themselves from obedience to the laws they make, and suit the law, both in its making, and execution, to their own private advantage...

It is the necessary, though very slow and gradual, consequence of a certain propensity in human nature which has in view no such extensive utility; the propensity to truck, barter, and exchange one thing for another.

The great thing, then, in all education, is to make our nervous system our ally instead of our enemy.

But if Germany, thanks to Hitler and his successors, were to enslave the European nations and destroy most of the treasures of their past, future historians would certainly pronounce that she had civilized Europe.

When the man governed by self-interest, the god of this world, does not renounce it but merely refines it by the use of reason and extends it beyond the constricting boundary of the present, he is represented (Luke XVI, 3-9) as one who, in his very person [as servant], defrauds his master [self- interest] and wins from him sacrifices in behalf of "duty."

As more and more women acquired prestige, fame, or money from feminist writings or from gains from feminist movement for equality in the workforce, individual opportunism undermined appeals for collective struggle. Women who were not opposed to patriarchy, capitalism, classism, or racism labeled themselves "feminist." Their expectations were varied. Privileged women wanted social equality with men of their class; some women wanted equal pay for equal work; others wanted an alternative lifestyle. Many of these legitimate concerns were easily co-opted by the ruling capitalist patriarchy.

As if to demonstrate, by a striking example, the impossibility of erecting any cerebral barrier between man and the apes, Nature has provided us, in the latter animals, with an almost complete series of gradations from brains little higher than that of a Rodent, to brains little lower than that of Man.

The violence of love is as much to be dreaded as that of hate. When it is durable, it is serene and equable. Even its famous pains begin only with the ebb of love, for few are indeed lovers, though all would fain be.

But oppression by your Mock-Superiors well shaken off, the grand problem yet remains to solve: That of finding government by your Real-Superiors! Alas, how shall we ever learn the solution of that, benighted, bewildered, sniffing, sneering, godforgetting unfortunates as we are? It is a work for centuries; to be taught us by tribulations, confusions, insurrections, obstructions; who knows if not by conflagration and despair! It is a lesson inclusive of all other lessons; the hardest of all lessons to learn.

Women are the most charitable creatures, and the most troublesome. He who shuns women passes up the trouble, but also the benefits. He who puts up with them gains the benefits, but also the trouble. As the saying goes, there's no honey without bees.

As all those have shown who have discussed civil institutions, and as every history is full of examples, it is necessary to whoever arranges to found a Republic and establish laws in it, to presuppose that all men are bad and that they will use their malignity of mind every time they have the opportunity; and if such malignity is hidden for a time, it proceeds from the unknown reason that would not be known because the experience of the contrary had not been seen, but time, which is said to be the father of every truth, will cause it to be discovered.

Human nature is evil, and goodness is caused by intentional activity.

As you say of yourself, I too am an Epicurian. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greece and Rome have left us.

A theory of cultural change is impossible without knowledge of the changing sense ratios effected by various externalizations of our senses.

For truth itself has not the privilege to be spoken at all times and in all sorts.

If the slave-owner of our times has no slave, John, whom he can send to the cesspool, he has five shillings, of which hundreds of such Johns are in such need that the slave-owner of our times may choose any one out of hundreds of Johns and be a benefactor to him by giving him the preference, and allowing him, rather than another, to climb down into the cesspool.

If you have money, don't lend it at interest. Rather, give it to someone from whom you won't get it back.

Till women are more rationally educated, the progress in human virtue and improvement in knowledge must receive continual checks.

Important though the general concepts and propositions may be with which the modern industrious passion for axiomatizing and generalizing has presented us, in algebra perhaps more than anywhere else, nevertheless I am convinced that the special problems in all their complexity constitute the stock and core of mathematics; and to master their difficulties requires on the whole the harder labor.

When we observe a thing, we see too much in it, we fall under the spell of the wealth of empirical detail which prevents us from clearly perceiving the notional determination which forms the core of the thing. The problem is thus not that of how to grasp the multiplicity of determinations, but rather to abstract from them, how to constrain our gaze and teach it to grasp only the notional determinism.

In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were an angel of the Lord to come and drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him. I am quite aware that we have just now lightheartedly expelled in imagination many excellent men who are largely, perhaps chiefly, responsible for the buildings of the temple of science; and in many cases, our angel would find it a pretty ticklish job to decide. But of one thing I feel sure: if the types we have just expelled were the only types there were, the temple would never have come to be, any more than a forest can grow which consists of nothing but creepers. For these people any sphere of human activity will do if it comes to a point; whether they become engineers, officers, tradesmen, or scientists depends on circumstances.Now let us have another look at those who have found favor with the angel. Most of them are somewhat odd, uncommunicative, solitary fellows, really less like each other, in spite of these common characteristics, than the hosts of the rejected. What has brought them to the temple? That is a difficult question and no single answer will cover it.

An anxious man constructs his terrors, then installs himself within them: a stay-at-home in a yawning chasm.

So near at hand is freedom, and is anyone still a slave?

How can it be that mathematics, being, after all, a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things?

This is the contradiction of racism, colonialism, and all forms of tyranny: in order to treat a man like a dog, one must first recognize him as a man.

There are two famous labyrinths where our reason very often goes astray. One concerns the great question of the free and the necessary, above all in the production and the origin of Evil. The other consists in the discussion of continuity, and of the indivisibles which appear to be the elements thereof, and where the consideration of the infinite must enter in.

The most violent revolutions in an individual's beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and one's own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.

But what is lawful for all extends across wide-ruling aether and, without cease, through endless sunshine.

A physician, after he had felt the pulse of Pausanias, and considered his constitution, saying, "He ails nothing," "It is because, sir," he replied, "I use none of your physic."

The many are mean; only the few are noble.

Even the death of Friends will inspire us as much as their lives. They will leave consolation to the mourners, as the rich leave money to defray the expenses of their funerals, and their memories will be incrusted over with sublime and pleasing thoughts, as monuments of other men are overgrown with moss; for our Friends have no place in the graveyard.

The most important feature of natural selection is that it is a process of drift. Evolution has no end-point or direction, so if the development of society is an evolutionary process it is one that is going nowhere.

Bourgeois civilization has built railroads and electric power plants, has invented explosives and airplanes, in order to create wealth. Imperialism has placed the tools of peace in the service of destruction. With modern means it would be easy to wipe out humanity at one blow.

The difference principle, for example, requires that the higher expectations of the more advantaged contribute to the prospects of the least advantaged.

I speak as a biologist. There aren't many absolutely clear distinctions in biology. Mostly what we have is a spectrum. But the male-female divide is exceptional in biology. It really is a true binary.

Here the institution that compels is the state, the only purpose of which is to protect individuals from one another and the whole from external enemies. Some German philosophasters of this mercenary age would like to twist it into an institution for education and edification in morality; in the background of this lurks the Jesuitical purpose of eliminating personal freedom and the individual's personal development in order to make him into a mere cog in a Chinese machine of state and religion. But this is the path by which in the past one has arrived at the inquisitions, burning of heretics, and religious wars; Frederick the Great's pledge, 'In my country, each shall be able to tend to his salvation in his own fashion', indicated that he never wanted to tread that path.

Logos is powerless without the force of eros.
