The intellectual world is divided into two classes - dilettantes, on the one hand, and pedants, on the other.

The eye of the intellect "sees in all objects what it brought with it the means of seeing."

A thinker sees his own actions as experiments and questions as attempts to find out something. Success and failure are for him answers above all.

In democratic countries, the most important private organizations are economic. Unlike secret societies, they are able to exercize their terrorism without illegality, since they do not threaten to kill their enemies, but only to starve them.

In the same way as philosophy loses sight of its true object and appropriate matter, when either it passes into and merges in theology, or meddles with external politics, so also does it mar its proper form when it attempts to mimic the rigorous method of mathematics.

The ontological concept of truth is in the centre of a logic which may serve as a model of pre- technological rationality. It is the rationality of a two-dimensional universe of discourse which, contrasts with the of thought and behavior that develop in the execution of the technological project.

I believe that man is in the last resort so free a being that his right to be what he believes himself to be cannot be contested.

We must relearn to be alone.

To speak ill of others is a dishonest way of praising ourselves; let us be above such transparent egotism. If you can't say good and encouraging things, say nothing. Nothing is often a good thing to do, and always a clever thing to say.

The detour to ideality leads to coinciding with oneself, that is, to certainty, which remains the guide and guarantee of the whole spiritual adventure of being.

People talk, indeed, of a "primitive mentality", as, for example, to-day that of the inferior races, and in days gone by that of humanity in general, at whose door the responsibility for superstition should be laid.

The advantage of meditating upon life and death is being able to say anything at all about them.

Through a wise and salutary neglect [of the colonies], a generous nature has been suffered to take her own way to perfection; when I reflect upon these effects, when I see how profitable they have been to us, I feel all the pride of power sink and all presumption in the wisdom of human contrivances melt and die away within me. My vigour relents. I pardon something to the spirit of liberty.

Countless attempts have been made to no avail to construct a continuity from the supreme principle of the intellectual world to the finite world. The oldest and most frequent of these attempts is well known: the principle of emanation, according to which the outflowings from the godhead, in gradual increments and detachment from the ordinary source, losing their divine perfection until, in the end, they pass into the opposite (matter, privation), just as light is finally confined by darkness.

Whatever you can lose, you should reckon of no account.

Die before you Die. There is no chance after.

A living language can stand on a higher level of culture in comparison with another, but it can never in itself attain that perfection of development which a dead language quite easily attains. In the latter the connotation of words is fixed, and the possibilities of suitable combinations will also gradually become exhausted. Hence, he who wishes to speak this language must speak it just as it is; but, after he has once learnt to do this, the language speaks itself in his mouth and thinks and imagines for him.

He dies twice who perishes by his own hand.

The ways of thinking implanted by electronic culture are very different from those fostered by print culture. Since the Renaissance most methods and procedures have strongly tended towards stress on the visual organization of knowledge.

When navigators... determine a longitude... they must... calculate Paris time…with a chronometer set for Paris. The qualitative problem of simultaneity is made to depend upon the quantitative problem of the measurement of time.

Money is human happiness in the abstract: he, then, who is no longer capable of enjoying human happiness in the concrete devotes his heart entirely to money.

I confess I have no great notion of the use of books, except to amuse a railway journey; although, I believe, there are some very exact treatises on astronomy, the use of the globes, agriculture, and the art of making paper flowers. Upon the less apparent provinces of life I fear you will find nothing truthful.

The commodity is first of all, an external object, a thing which through its qualities satisfies human needs of whatever kind. The nature of these needs, whether they arise, for example, from the stomach, or the imagination, makes no difference. Nor does it matter here how the thing satisfies man's need, whether directly as a means of subsistence, i.e. an object of consumption, or indirectly as a means of production.

We can hope that the ways of peace will attract the Arabic nations, for their territory and opportunities are broad enough for immeasurable advance, if the energies vented in spleen, are turned instead to a modernisation of the technology, a restoration of the soil, and a renovation of the economic, social, and political structure of those great and venerable lands.

The time would fail me if I were to recite all the big names in history whose exploits are perfectly irrational and even shocking to the business mind. The incongruity is speaking; and I imagine it must engender among the mediocrities a very peculiar attitude, towards the nobler and showier sides of national life.

As long as politics is the shadow cast on society by big business, the attenuation of the shadow will not change the substance.

Cultural dominance by either the left or the right hemisphere is largely dependent upon environmental factors.

History tells us of innumerable retrogressions, of decadences and degenerations. But nothing tells us that there is no possibility of much more basic retrogressions than any so far known, including the most radical of all: the total disappearance of man as man and his silent return to the animal scale, to complete and definitive alteration. The fate of culture, the destiny of man, depends upon our maintaining this dramatic consciousness ever alive in our inmost being, and upon our being well aware, as of a murmuring counterpoint in our entrails, that we can only be sure of insecurity.

The suffering man ought really 'to consume his own smoke'; there is no good in emitting smoke till you have made it into fire, - which, in the metaphorical sense too, all smoke is capable of becoming!

Too little liberty brings stagnation, and too much brings chaos.

Every process pushed far enough tends to reverse or flip suddenly. Chiasmus - the reversal to process caused by increasing its speed, scope or size.

If evolution is a struggle for survival, why hasn't it ruthlessly eliminated altruists, who seem to increase another's prospects of survival at the cost of their own?

As we shall see later, the most important factor in the training of good mental habits consists in acquiring the attitude of suspended conclusion, and in mastering the various methods of searching for new materials to corroborate or to refute the first suggestions that occur. To maintain the state of doubt and to carry on systematic and protracted inquiry ― these are the essentials of thinking.

Architecture is a way for power to achieve eloquence through form.

I wanted for the moments in my life to follow each other and order themselves like those of a life remembered. It would be just as well to try to catch time by the tail.

I was obliged to retract, like a good Catholic, this opinion of mine; and as a punishment my dialogue was prohibited; and after five months being dismissed from Rome (at the time that the city of Florence was infected with plague), the habitation which with generous pity was assigned to me, was that of the dearest friend I had in Siena, Monsignor the Archbishop Piccolomini, whose most agreeable conversation I enjoyed with such quite and satisfaction of mind, that having there resumed my studies, I discovered and demonstrated a great number on the mechanical conclusions on the resistance of solids ... after about five months, the pestilence having ceased, the confinement of that house was changed by His Holiness for the freedom of the country so agreeable to me, whence I returned to the villa of Bellosguardo, and afterwards to Arcetri, where I still breathe salubrious air near my dear native-country Florence.

"Then those people are right who say that Heaven and Hell are only states of mind?" "Hush," he said sternly. "Do not blaspheme. Hell is a state of mind - ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind - is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself. All that is fully real is Heavenly."

We cannot avoid conflict, conflict with society, other individuals and with oneself. Conflicts may be the sources of defeat, lost life and a limitation of our potentiality but they may also lead to greater depth of living and the birth of more far-reaching unities, which flourish in the tensions that engender them.

I retain my faith in the humanist tradition, that it's possible to deal with discrepant experiences truthfully without resolving into simple things like only women should write about women, only Chicanos should write about Chicanos, only Latinos should write about Latinos... I think that's the most damaging crime, and misapprehension of what I'm saying. That's why they debate all these things and they trace them back to me and people say 'you did that!' Absolutely not. I'm talking from a universalistic, if you like cosmopolitan point of view to which I adhere and which is the only way the world makes sense to me. I don't believe in the politics of identity, although in many ways paradoxically I seem to be the father of identity politics, but it's a thing I totally disbelieve in because I realise the damage that identities have done.

Philosophers do not claim that God does not know particulars; they rather claim that He does not know them the way humans do. God knows particulars as their Creator whereas humans know them as a privileged creations of God might know them.

In a general way, the literature of the twentieth century is essentially psychological; and psychology consists of describing states of the soul by displaying them all on the same plane, without any discrimination of value, as though good and evil were external to them, as though the effort toward the good could be absent at any moment from the thought of any man.

In the late eighteenth and the greater part of the nineteenth centuries appeared the first marked cultural shift in the attitude taken toward change. Under the names of indefinite perfectibility, progress, and evolution, the movement of things in the universe itself and of the universe as a whole began to take on a beneficent instead of hateful aspect.

When it is evening, ye say, It will be fair weather: for the sky is red. And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times? A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas.

Beauty is indeed a good gift of God; but that the good may not think it a great good, God dispenses it even to the wicked.

The Americans have always been more open to my ideas. In fact, I could earn a living in America just by lecturing. One of my brightest audiences, incidentally, were the prisoners in a Philadelphia gaol - brighter than my students at university.

In Oran, as elsewhere, for want of time and thought, people have to love one another without knowing it.

And the conversion of the other Don Quixote - he who was converted only to die - was possible because he was mad, and it was his madness, and not his death or his conversion that immortalized him, earning him forgiveness for this crime of having been born. Felix culpa! And neither was his madness cured, but only transformed. His death was his last knightly adventure; in dying he stormed heaven, which suffereth violence.

The Age that admires talk so much can have little discernment for inarticulate work, or for anything that is deep and genuine. Nobody, or hardly anybody, having in himself an earnest sense for truth, how can anybody recognize an inarticulate Veracity, or Nature-fact of any kind; a Human Doer especially, who is the most complex, profound, and inarticulate of all Nature's Facts? Nobody can recognize him: till once he is patented, get some public stamp of authenticity, and has been articulately proclaimed, and asserted to be a Doer. To the worshipper of talk, such a one is a sealed book. An excellent human soul, direct from Heaven,-how shall any excellence of man become recognizable to this unfortunate? Not except by announcing and placarding itself as excellent,-which, I reckon, it above other things will probably be in no great haste to do.

Logic takes care of itself; all we have to do is to look and see how it does it.

Not one of these nobly equipped young men has escaped the restless, exhausting, confusing, debilitating crisis of education. ... He feels that he cannot guide himself, cannot help himself, and then he dives hopelessly into the world of everyday life and daily routine, he is immersed in the most trivial activity possible, and his limbs grow weak and weary.
