Rules for Definitions. I. Not to undertake to define any of the things so well known of themselves that the clearer terms cannot be had to explain them. II. Not to leave any terms that are at all obscure or ambiguous without definition. III. Not to employ in the definition of terms any words but such as are perfectly known or already explained.

I consider as lovers of books not those who keep their books hidden in their store-chests and never handle them, but those who, by nightly as well as daily use thumb them, batter them, wear them out, who fill out all the margins with annotations of many kinds, and who prefer the marks of a fault they have erased to a neat copy full of faults.

All religions promise a reward for excellences of the will or heart, but none for excellences of the head or understanding.

What appears to us to be an accurate definition of justice does not also appear to be so to the Gods. For we, looking to that which is most brief, direct our attention to things present, and to this momentary life, and the manner in which it subsists. But the Powers that are superior to us know the whole life of the Soul, and all its former lives.

I'm not one of those who wants to stop Christian traditions. This is historically a Christian country. I'm a cultural Christian the same way as many of my friends call themselves cultural Jews or cultural Muslims. So, yes, I love singing carols along with everybody else. I'm not one of those who wants to purge our society of our Christian history.

The product of mental labor - science - always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.

Under the ideal measure of values there lurks the hard cash.

I want to have her back as an ingredient in the restoration of my past. Could I have wished her anything worse? Having got once through death, to come back and then, at some later date, have all her dying to do all over again? They call Stephen the first martyr. Hadn't Lazarus the rawer deal?

The essence of our God is obscure. It ripens continuously; perhaps victory is strenghened with our every valorous deed, but perhaps even all these agonizing struggles toward deliverance and victory are inferior to the nature of divinity. Whatever it might be, we fight on without certainty, and our virtue, uncertain of any rewards, acquires a profound nobility.

I will remark again, however, as a fact not unimportant to be understood, that the different sphere constitutes the grand origin of such distinction; that the Hero can be Poet, Prophet, King, Priest or what you will, according to the kind of world he finds himself born into. I confess, I have no notion of a truly great man that could not be all sorts of men.

In all human affairs, and especially in those that relate to war, ...leave always some room to fortune, and to accidents which cannot be foreseen.

The words of malicious slander should not be allowed to enter the ear. A defensive voice should not be allowed to come out of the mouth. The want to gravely injure people should not be allowed to exist in the heart. If this is accomplished, though there be people who cynically expose others, they would be without people who would align with them.

Were the happiness of the next world as closely apprehended as the felicities of this, it were a martyrdom to live.

Someday the old shack we call the world will fall apart. How, we don't know, and we don't really care either. Since nothing has real substance, and life is a twirl in the void, its beginning and its end are meaningless.

He who is in love is wise and is becoming wiser, sees newly every time he looks at the object beloved, drawing from it with his eyes and his mind those virtues which it possesses.

Even opinion is of force enough to make itself to be espoused at the expense of life.

When we reflect, that the Inquisition, by its restrictions, and authority, would have prevented the French revolution,-it is hard to say, whether the Sovereign, who, wholly, and without reserve, gave up this instrument, would not, in reality, be doing an injury to humanity.

Carnap made a detailed analysis of Heidegger's statement, "Nothing nihilates," in order to show that it is purely verbal, devoid of empirical meaning. (Incidentally, this is the only sentence from existentialist philosophy the majority of contemporary positivists appear familiar with.)

One could count on one's fingers the number of scientists in the entire world who have a general idea of the history and development of their own particular science; there is not one who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, any scientists, but only drudges doing scientific work. . . .

The concept of space, therefore, is a pure intuition, being a singular concept, not made up by sensations, but itself the fundamental form of all external sensation.

Every political good carried to the extreme must be productive of evil.

Whoever cultivates the golden mean avoids both the poverty of a hovel and the envy of a palace.

People are said to believe in God, or to disbelieve in Adam and Eve. But in such cases what is believed or disbelieved is that there is an entity answering a certain description. This, which can be believed or disbelieved is quite different from the actual entity (if any) which does answer the description. Thus the matter of belief is, in all cases, different in kind from the matter of sensation or presentation, and error is in no way analogous to hallucination. A hallucination is a fact, not an error; what is erroneous is a judgment based upon it.

For Leopardi evil is integral to the way the world works; but when he talks of evil he does not mean any kind of malign agency of the sort that Gnostics imagined. Evil is the suffering that is built into the scheme of things. 'What hope is there when evil is ordinary?' he asks. 'I mean, in an order where evil is necessary?' These rhetorical questions show why Leopardi had no interest in projects of revolution and reform. No type of human action - least of all the harlequinade of politics - could fundamentally alter a world in which evil was ordinary.

When I am furious about something, I sometimes beat the ground or a tree with my walking stick. But I certainly do not believe that the ground is to blame or that my beating can help anything... And all rites are of this kind.

Half of the human race lives in manifest obedience to the lunar rhythm; and there is evidence to show that the psychological and therefore the spiritual life, not only of women, but of men too, mysteriously ebbs and flows with the changes of the moon. There are unreasoned joys, inexplicable miseries, laughters and remorses without a cause. Their sudden and fantastic alternations constitute the ordinary weather of our minds. These moods, of which the more gravely numinous may be hypostasized as gods, the lighter, if we will, as hobgoblins and fairies, are the children of the blood and humours. But the blood and humours obey, among many other masters, the changing moon. Touching the soul directly through the eyes and, indirectly, along the dark channels of the blood, the moon is doubly a divinity.

And why were those haughty [French] nobles destroyed with that utter destruction? Why were they scattered over the face of the earth, their titles abolished, their escutcheons defaced, their parks wasted, their palaces dismantled, their heritage given to strangers? Because they had no sympathy with the people, no discernment of the signs of their time; because, in the pride and narrowness of their hearts, they called those whose warnings might have saved them theorists and speculators; because they refused all concession till the time had arrived when no concession would avail.

Rome is the Great Beast of atheism and materialism, adoring nothing but itself. Israel is the Great Beast of religion. Neither one nor the other is likable. The Great Beast is always repulsive.

The Asharites have expressed a very peculiar opinion, both with regard to reason and religion; about this problem they have explained it in a way in which religion has not, but have adopted quite an opposite method.

Many have been deceived by outward appearances and have proceeded to write and teach about good works and how they justify without even mentioning faith. ... Wearying themselves with many works, they never come to righteousness.

In an ever-changing, incomprehensible world the masses had reached the point where they would, at the same time, believe everything and nothing, think that everything was possible and that nothing was true. [...] under such conditions, one could make people believe the most fantastic statements one day, and trust that if the next day they were given irrefutable proof of their falsehood, they would take refuge in cynicism; instead of deserting the leaders who had lied to them, they would protest that they had known all along that the statement was a lie and would admire the leaders for their superior tactical cleverness.

Knowledge is the plague of life, and consciousness, an open wound in its heart.

The metaphysical apologia at least betrayed the injustice of the established order through the incongruence of concept and reality. The impartiality of scientific language deprived what was powerless of the strength to make itself heard and merely provided the existing order with a neutral sign for itself. Such neutrality is more metaphysical than metaphysics.

The critical ontology of ourselves has to be considered not, certainly, as a theory, a doctrine, nor even as a permanent body of knowledge that is accumulating; it has to be conceived as an attitude, an ethos, a philosophical life in which the critique of what we are is at one and the same time the historical analysis of the limits that are imposed on us and an experiment with the possibility of going beyond them.

The way of Heaven and Earth may be completely declared in one sentence: They are without any doubleness, and so they produce things in a manner that is unfathomable.

Force is the midwife of every old society pregnant with a new one. It is itself an economic power.

It is a safe rule to apply that, when a mathematical or philosophical author writes with a misty profundity, he is talking nonsense.

The punctuation of anniversaries is terrible, like the closing of doors, one after another between you and what you want to hold on to.

If wine is to withdraw its most poetic countenance, the sun of the white dinner-cloth, a deity to be invoked by two or three, all fervent, hushing their talk, degusting tenderly, and storing reminiscences-for a bottle of good wine, like a good act, shines ever in the retrospect-if wine is to desert us, go thy ways, old Jack!

By Thy perfect Intelligence, O MazdaThou didst first create us having bodies and spiritual consciences,And by Thy Thought gave our selves the power of thought, word, and deed.Thus leaving us free to choose our faith at our own will.

To SEE and accept the boundaries of the human mind without vain rebellion, and in these severe limitations to work ceaselessly without protest - this is where man's first duty lies.

Art is thought, and thought only gives the world an appearance of order to anyone weak enough to be convinced by its show.

Morality knows nothing of geographical boundaries, or distinctions of race.

The process of being brought up, however well it is done, cannot fail to offend.

When we cannot be delivered from ourselves, we delight in devouring ourselves.

The greatest problem for the human race, to the solution of which Nature drives man, is the achievement of a universal civic society which administers law among men.
