There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.

A plant, an animal, the regular order of nature - probably also the disposition of the whole universe - give manifest evidence that they are possible only by means of and according to ideas; that, indeed, no one creature, under the individual conditions of its existence, perfectly harmonizes with the idea of the most perfect of its kind - just as little as man with the idea of humanity, which nevertheless he bears in his soul as the archetypal standard of his actions; that, notwithstanding, these ideas are in the highest sense individually, unchangeably, and completely determined, and are the original causes of things; and that the totality of connected objects in the universe is alone fully adequate to that idea.

The totalitarian states, whether of the fascist or the communist persuasion, are more than superficially alike as dictatorships, in the suppression of dissent, and in operating planned and directed economies. They are profoundly alike.

Christ is not valued at all unless He be valued above all.

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 man living without conflicts, as if he never lives at all.

When he was asked what advantage had accrued to him from philosophy, his answer was, "The ability to hold converse with myself."

The encouragement of light-mindedness about traditional philosophical topics serves the same purposes as does the encouragement of light-mindedness about traditional theological topics. Like the rise of large market economies, the increase in literacy, the proliferation of artistic genres, and the insouciant pluralism of contemporary culture, such philosophical superficiality and light-mindedness helps along the disenchantment of the world. It helps make the world's inhabitants more pragmatic, more tolerant, more liberal, more receptive to the appeal of instrumental rationality.

In the greatest confusion there is still an open channel to the soul. It may be difficult to find because by midlife it is overgrown, and some of the wildest thickets that surround it grow out of what we describe as our education. But the channel is always there, and it is our business to keep it open, to have access to the deepest part of ourselves.

What is Nature? An encyclopedical, systematic Index or Plan of our Spirit. Why will we content us with the mere catalogue of our Treasures? Let us contemplate them ourselves, and in all ways elaborate and use them.

The greatest states have been overthrown by the young and sustained and restored by the old. ... Rashness is the product of the budding-time of youth, prudence of the harvest-time of age.

Man must not only make himself: the weightiest thing he has to do is to determine what he is going to be. He is causa sui to the second power.

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

A spider conducts operations that resemble those of a weaver, and a bee puts to shame many an architect in the construction of her cells. But what distinguishes the worst of architects from the best of bees is this, that the architect raises his structure in imagination before he erects it in reality.

A witty saying proves nothing.

There is no means of proving it is preferable to be than not to be.

In America, more than anywhere else in the world, care has been taken constantly to trace clearly distinct spheres of action for the two sexes, and both are required to keep in step, but along paths that are never the same.

Nature is no sentimentalist, - does not cosset or pamper us. We must see that the world is rough and surly, and will not mind drowning a man or a woman, but swallows your ships like a grain of dust. The cold, inconsiderate of persons, tingles your blood, benumbs your feet, freezes a man like an apple. The diseases, the elements, fortune, gravity, lightning, respect no persons.

To challenge and to cope with this paradoxical state of things, we need a paradoxical way of thinking; since the world drifts into delirium, we must adopt a delirious point of view. We must no longer assume any principle of truth, of causality, or any discursive norm. Instead, we must grant both the poetic singularity of events and the radical uncertainty of events. It is not easy. We usually think that holding to the protocols of experimentation and verification is the most difficult thing. But in fact the most difficult thing is to renounce the truth and the possibility of verification, to remain as long as possible on the enigmatic, ambivalent, and reversible side of thought.

At different degrees, everything is pathology, except for indifference.

Pragmatism starts from assumptions similar to those of empiriocriticism, but differs from the latter by its striking formulations, loose aphorisms, and analytical unscrupulousness.

Revolutionaries do not make revolutions! The revolutionaries are those who know when power is lying in the street and when they can pick it up. Armed uprising by itself has never yet led to revolution.

Yet a man may love a paradox, without losing either his wit or his honesty.

Unlimited exploitation of cheap labour-power is the sole foundation of their power to compete.

In places where men are used to differences they inevitably become tolerant.

I know how unfashionable it is now to acknowledge in life or history any genius loftier than ourselves. Our democratic dogma has leveled not only all voters but all leaders; we delight to show that living geniuses are only mediocrities, and that dead ones are myths. ... Since it is contrary to good manners to exalt ourselves, we achieve the same result by slyly indicating how inferior are the great men of the earth. In some of us, perhaps, it is a noble and merciless asceticism, which would root out of our hearts the last vestige of worship and adoration, lest the old gods should return and terrify us again. For my part, I cling to this final religion, and discover in it a content and stimulus more lasting than came from the devotional ecstasies of youth.

Further, it will not be amiss to distinguish the three kinds and, as it were, grades of ambition in mankind. The first is of those who desire to extend their own power in their native country, a vulgar and degenerate kind. The second is of those who labor to extend the power and dominion of their country among men. This certainly has more dignity, though not less covetousness. But if a man endeavor to establish and extend the power and dominion of the human race itself over the universe, his ambition (if ambition it can be called) is without doubt both a more wholesome and a more noble thing than the other two. Now the empire of man over things depends wholly on the arts and sciences. For we cannot command nature except by obeying her.

A great affliction of all Philistines is that idealities afford them no entertainment, but to escape from boredom they are always in need of realities.

Fundamentally we are highly social creatures. We feel a big sense of anomie and discomfort when we are isolated from our fellow human beings. …We seek community in different ways. There's a right wing... and... a left wing version of this.

The uttered part of a man's life, let us always repeat, bears to the unuttered, unconscious part a small unknown proportion. He himself never knows it, much less do others.

It makes a tremendous emotional and practical difference to one whether one accepts the universe in the drab discolored way of stoic resignation to necessity, or with the passionate happiness of Christian saints.

For what else are you busied with except improving yourself every day, laying aside some error, and coming to understand that the faults which you attribute to circumstances are in yourself?

The Public is an old woman. Let her maunder and mumble.

We may well call it black diamonds. Every basket is power and civilization. For coal is a portable climate. It carries the heat of the tropics to Labrador and the polar circle; and it is the means of transporting itself withersoever it is wanted. Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comfort brings its industrial power.

I do not know what postmodern is and how it differs from the premodern, nor do I feel that I ought to know.

Life has always seemed to me like a plant that lives on its rhizome. Its true life is invisible, hidden in the rhizome. The part that appears above ground lasts only a single summer. What we see is the blossom, which passes. The rhizome remains. Closing lines of the preface

Courtesy is a science of the highest importance. It is, like grace and beauty in the body, which charm at first sight, and lead on to further intimacy and friendship, opening a door that we may derive instruction from the example of others, and at the same time enabling us to benefit them by our example, if there be anything in our character worthy of imitation.

India will teach us the tolerance and gentleness of mature mind, understanding spirit and a unifying, pacifying love for all human beings.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

Abjection is a methodological conversion, like Cartesian doubt and Husserlian epoche: it establishes the world as a closed system which consciousness regards from without, in the manner of divine understanding.

All greatness is unconscious, or it is little and naught.

The basis of our government being the opinion of the people, the very first object should be to keep that right; and were it left to me to decide whether we should have a government without newspapers, or newspapers without a government, I should not hesitate a moment to prefer the latter. But I should mean that every man should receive those papers and be capable of reading them.

Alexander, king of Macedon, began to study geometry; unhappy man, because he would thereby learn how puny was that earth of which he had seized but a fraction! Unhappy man, I repeat, because he was bound to understand that he was bearing a false title. For who can be "great" in that which is puny?

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all.
