A grievous crime indeed against religion has been committed by the man who imagines that Islam is defended by the denial of the mathematical sciences.

I maintain that in every special natural doctrine only so much science proper is to be met with as mathematics; for... science proper, especially of nature, requires a pure portion, lying at the foundation of the empirical, and based upon à priori knowledge of natural things. ...the conception should be constructed. But the cognition of the reason through construction of conceptions is mathematical. A pure philosophy of nature in general, namely, one that only investigates what constitutes a nature in general, may thus be possible without mathematics; but a pure doctrine of nature respecting determinate natural things (corporeal doctrine and mental doctrine), is only possible by means of mathematics; and as in every natural doctrine only so much science proper is to be met with therein as there is cognition à priori, a doctrine of nature can only contain so much science proper as there is in it of applied mathematics.

The only man for whom Hitler had "unqualified respect" was "Stalin the genius," and while in the case of Stalin and the Russian regime we do not... have the rich documentary material that is available for Germany, we nevertheless know since Khrushchev's speech before the Twentieth Party Congress that Stalin trusted only one man and that was Hitler.

Man does not exercise his thought because he finds it amusing, but because, obliged as he is to live immersed in the world and to force his way among things, he finds himself under the necessity of organizing his psychic activities, which are not very different from those of the anthropoid, in the form of thought - which is what the animal does not do.

Paper, they say, does not blush, but I assure you it's not true and that it's blushing just as I am now, all over.

Reading after a certain age diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theater is tempted to be content with living vicariously instead of living his own life.

Thus, all unknown quantities can be expressed in terms of a single quantity, whenever the problem can be constructed by means of circles and straight lines, or by conic sections, or even by some other curve of degree not greater than the third or fourth.But I shall not stop to explain this in more detail, because I should deprive you of the pleasure of mastering it yourself, as well as of the advantage of training your mind by working over it, which is in my opinion the principal benefit to be derived from this science. Because, I find nothing here so difficult that it cannot be worked out by anyone at all familiar with ordinary geometry and with algebra, who will consider carefully all that is set forth in this treatise.

Sartre observed that he had never felt so free as during the German occupation when (as a member of the French resistance) he was in constant danger of being arrested and shot. Could there be a more conclusive proof that human beings are freer than they realize, and that their freedom is eroded by habit and laziness?

There is no virtue they should be excited to, nor fault they should be kept from, which I do not think they may be convinced of; but it must be by such reasons as their age and understandings are capable of, and those propos'd always in very few and plain words.

I am sorry that my convictions do not allow me to repeat my friend's offer, said one of the others. But I have had to abandon the humanitarian and egalitarian fancies. His name was Mr. Neo-Classical.

I like to walk about amidst the beautiful things that adorn the world; but private wealth I should decline, or any sort of personal possessions, because they would take away my liberty.

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

Everywhere we remain unfree and chained to technology, whether we passionately affirm or deny it. But we are delivered over to it in the worst possible way when we regard it as something neutral; for this conception of it, to which today we particularly like to do homage, makes us utterly blind to the essence of technology.

I am not asking anyone to accept Christianity if his best reasoning tells him that the weight of the evidence is against it.

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.

There are necessities and impossibilities in reality which do not obtain in fiction, any more than the law of gravity to which we are subject controls what is represented in a picture. ... It is the same with pure good; for a necessity as strong as gravity condemns man to evil and forbids him any good, or only within the narrowest limits and laboriously obtained and soiled and adulterated with evil. ... The simplicity which makes the fictional good something insipid and unable to hold the attention becomes, in the real good, an unfathomable marvel.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

Man is always separated from what he is by all the breadth of the being which he is not. He makes himself known to himself from the other side of the world and he looks from the horizon toward himself to recover his inner being.

Oh providence! Oh nature! Treasure of the poor, resource of the unfortunate. The person who feels, knows your holy laws and trusts them, the person whose heart is at peace and whose body does not suffer, thanks to you is not entirely prey to adversity.

No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow.

The 'intense life' advertised by the neoliberal regime is in truth simply a life of intense consumption.

The world neither ever saw, nor ever will see, a perfectly fair lottery.

It is from the shadow of a cloister that there emerges one of mankind's greatest very greatest scourges. Luther appears; Calvin follows him. The Peasants' Revolt; the Thirty Years' War; the civil war in France; the massacre of the Low Countries; the massacre of Ireland; the massacre of the Cévennes; St Bartholomew's Day; the murders of Henry II, Henry IV, Mary Stuart, and Charles I; and finally, in our day, from the same source, the French Revolution.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

In fact, it is as difficult to appropriate the thoughts of others as it is to invent.

The cravings of love and sex are met with absolute ignorance by the majority of parents, who consider it as something indecent and improper, something disgraceful, almost criminal, to be suppressed and fought like some terrible disease. The love and tender feelings in the young plant are turned into vulgarity and coarseness through the stupidity of those surrounding it, so that everything fine and beautiful is either crushed altogether or hidden in the innermost depths, as a great sin, that dares not face the light.

For all knowledge and wonder (which is the seed of knowledge) is an impression of pleasure in itself.

"A pleasure is full grown only when it is remembered. You are speaking, Hmān, as if the pleasure were one thing and the memory another. It is all one thing. The séroni could say it better than I say it now. Not better than I could say it in a poem. What you call remembering is the last part of the pleasure, as the crah is the last part of a poem. When you and I met, the meeting was over very shortly, it was nothing. Now it is growing something as we remember it. But still we know very little about it. What it will be when I remember it as I lie down to die, what it makes in me all my days till then-that is the real meeting. The other is only the beginning of it."

Do not be too moral. You may cheat yourself out of much life so. Aim above morality. Be not simply good; be good for something.

Courtiers don't take wagers against the king's skill.

All those movements which took place in the fifteenth and sixteenth centuries and which had the Reformation as their main expression and result should be analyzed as a great crisis of the Western experience of subjectivity and a revolt against the kind of religious and moral power which gave form, during the Middle Ages, to this subjectivity. The need to take a direct part in spiritual life, in the work of salvation, in the truth which lies in the Book-all that was a struggle for a new subjectivity.

The end of man (as a factual anthropological limit) is announced to thought from the vantage of the end of man (as a determined opening or the infinity of a telos). Man is that which is in relation to his end, in the fundamentally equivocal sense of the word. Since always.

corporate globalization is really about an aggressive privatization of the water, biodiversity, and food systems of the Earth, when these communities declare sovereignty and act on that sovereignty, they have developed a powerful response to globalization. Living democracy then is the democracy that is custodian of the living wealth on which people depend.

Man cannot be wicked without being evil, nor evil without being degraded, nor degraded without being punished, nor punished without being guilty. In short ... there is nothing so intrinsically plausible as the theory of original sin.

It is absurd to hold that a man ought to be ashamed of being unable to defend himself with his limbs but not of being unable to defend himself with reason when the use of reason is more distinctive of a human being than the use of his limbs.

Many a time I have wanted to stop talking and find out what I really believed.

The mass-man sees in the State an anonymous power, and feeling himself, like it, anonymous, he believes that the State is something of his own. Suppose that in the public life of a country some difficulty, conflict, or problem presents itself, the mass-man will tend to demand that the State intervene immediately and undertake a solution directly with its immense and unassailable resources. This is the gravest danger that to-day threatens civilisation: State intervention; the absorption of all spontaneous social effort by the State.

People don't want to be understood - I mean not completely. It's too destructive. Then they haven't anything left.

But what can be the attraction of getting to know such a tiny section of nature thoroughly, while one leaves everything subtler and more complex shyly and timidly alone? Does the product of such a modest effort deserve to be called by the proud name of a theory of the universe? In my belief the name is justified; for the general laws on which the structure of theoretical physics is based claim to be valid for any natural phenomenon whatsoever. With them, it ought to be possible to arrive at the description, that is to say, the theory, of every natural process, including life, by means of pure deduction, if that process of deduction were not far beyond the capacity of the human intellect. The physicist's renunciation of completeness for his cosmos is therefore not a matter of fundamental principle.

Predicting the future is a hopeless, thankless task, with ridicule to begin with and, all too often, scorn to end with.

Perfect humility dispenses with modesty.

He and his tyrannicide! I am in a mad fury about these explosions. If that is the new world! Damn O'Donovan Rossa; damn him behind and before, above, below, and roundabout; damn, deracinate, and destroy him, root and branch, self and company, world without end. Amen. I write that for sport if you like, but I will pray in earnest, O Lord, if you cannot convert, kindly delete him!

"A fair day's wages for a fair day's work": it is as just a demand as governed men ever made of governing. It is the everlasting right of man.

The wife of my God is matter; they wrestle with each other, they laugh and weep, they cry out in the nuptial bed of flesh. They spawn and are dismembered. They fill sea, land, and air with species of plants, animals, men, and spirits. This primordial pair embraces, is dismembered, and multiplies in every living creature. All the concentrated agony of the Universe bursts out in every living thing. God is imperiled in the sweet ecstasy and bitterness of flesh. But he shakes himself free, he leaps out of brains and loins, then clings to new brains and new loins until the struggle for liberation again breaks out from the beginning.

As we can not give a general definition of energy, the principle of the conservation of energy signifies simply that there is something which remains constant.
