When you know quite absolutely that everything is unreal, you then cannot see why you should take the trouble to prove it.

As an empiricist I continue to think of the conceptual scheme of science as a tool, ultimately, for predicting future experience in the light of past experience. Physical objects are conceptually imported into the situation as convenient intermediaries-not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer. For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience.

By Natura naturans we must understand what is in itself and is conceived through itself, or such attributes of substance as express an eternal and infinite essence, that is ... God, insofar as he is considered as a free cause. But by Natura naturata I understand whatever follows from the necessity of God's nature, or from God's attributes, that is, all the modes of God's attributes insofar as they are considered as things which are in God, and can neither be nor be conceived without God.

If man of himself could in a perfect manner know all things visible and invisible, it would indeed be foolish to believe what he does not see. But our manner of knowing is so weak that no philosopher could perfectly investigate the nature of even one little fly.

Character is higher than intellect...A great soul will be strong to live, as well as strong to think.

All that Mankind has done, thought, gained or been: it is lying as in magic preservation in the pages of Books.

No text in the tradition seems as lucid concerning the way in which the political is becoming worldwide. concerning the irreducibility of the technical and the media in the current of the most thinking thought-and this goes beyond the railroad and the newspapers of the time whose powers were analyzed in such an incomparable way in the Manifesto. And few texts have shed so much light on law. international law. and nationalism.

A man's thinking goes on within his consciousness in a seclusion in comparison with which any physical seclusion is an exhibition to public view.

There is no greater fallacy than the belief that aims and purposes are one thing, while methods and tactics are another, This conception is a potent menace to social regeneration. All human experience teaches that methods and means cannot be separated from the ultimate aim. The means employed become, through individual habit and social practice, part and parcel of the final purpose; they influence it, modify it, and presently the aims and means become identical.

But for my part (Continues Carneades) what my Indignation at this Un-philosophical way of teaching Principles has now extorted from me, is meant chiefly to excuse my self, if I shall hereafter oppose any Particular Opinion or assertion, that some Follower of Paracelsus or any Eminent Artist may pretend not to be his Masters. For, as I told you long since, I am not Oblig'd to examine private mens writings, (which were a Labour as endless as unprofitable) being only engag'd to examine those Opinions about the Tria Prima, which I find those Chymists I have met with to agree in most: And I Doubt not but my Arguments against their Doctrine will be in great part easily enough applicable ev'n to those private Opinions, which they do not so directly and expresly oppose.

Man is a tool-using animal...Without tools he is nothing, with tools he is all.

And these were the dishes wherein to me, hunger-starven for thee, they served up the sun and the moon.

Most men's conscience, habits, and opinions are borrowed from convention and gather continual comforting assurances from the same social consensus that originally suggested them.

We all have a weakness for beauty.

While the Marxist faith in central planning is now confined to a few dingy sects, a quasi-religious belief in free markets continues to shape the policies of governments.Many writers have pointed to the havoc and ruin that have accompanied the imposition of free markets across the world. Whether in Africa, Asia, Latin America or post-communist Europe, policies of wholesale privatisation and structural adjustment have led to declining economic activity and social dislocation on a massive scale.

In fact, we had a number of extreme leftists and trade unionists among us, and they seemed to take it for granted that we all agreed that the rich must somehow be forced to surrender their ill-gotten gains. Yet there was an air of good humor about their idealism that made me feel they would not be too offended if I admitted that I regard socialists as well-meaning but muddle-headed brigands.

He came in sight of a pass guarded by armed men. 'you cannot pass ... Do you not know that all this country belongs to the Spirit of the Age? ... Here Enlightenment, take this fugitive to our Master.'

So long as men worship the Caesars and Napoleons, Caesars and Napoleons will duly rise and make them miserable.

When people come to me saying they want to kill themselves, I tell them, "What's your rush? You can kill yourself any time you like. So calm down. Suicide is a positive act." And they do calm down.

'The Law of Continuity' is this:-that a quantity cannot pass from one amount to another by any change of conditions, without passing through all intermediate magnitudes according to the intermediate conditions. It may often be employed to disprove distinctions which have no real foundation. 'The Method of Gradation' consists in taking a number of stages of a property in question, intermediate between two extreme cases which appear to be different. It is employed to determine whether the extreme cases are really distinct or not. 'The Method of Gradation', applied to decide the question, whether the existing phenomena arise from existing causes, leads to this result:-That the phenomena do appear to arise from existing causes, but that the action of existing causes have transgressed their recorded Limits of Intensity. 'The Method of Natural Classification' consists in classing cases, not according to any assumed definition, but according to the connexion of the facts themselves.

A definition may be very exact, and yet go but a very little way towards informing us of the nature of the thing defined.

In limitations he first shows himself the master,And the law can only bring us freedom.

We came to a tree which was still bare, and on which the birds were singing out gaily in the morning, without any fear of us. Then stooping over like an Indian on the hunt, my companion placed a pebble in the leather of his sling and stretched it. Obeying his peremptory glance I did the same, with frightful twinges of conscience, vowing firmly that I would shoot when he did. At that very moment the church bells began to sound, mingling with the song of the birds in the sunshine. It was the warning bell that came a half-hour before the main bell. For me it was a voice from heaven. I threw the sling down, scaring the birds away, so that they were safe from my companion's sling, and fled home. And ever afterwards when the bells of Holy Week ring out amidst the leafless trees in the sunshine I remember with moving gratitude how they rang into my heart at that time the commandment: Thou shalt not kill.

Beholding beauty with the eye of the mind, he will be enabled to bring forth, not images of beauty, but realities (for he has hold not of an image but of a reality), and bringing forth and nourishing true virtue to become the friend of God and be immortal, if mortal man may.

A sub-clerk in the post office is the equal of a conqueror if consciousness is common to them. All experiences are indifferent in this regard. There are some that do either a service or a disservice to man. They do him a service if he is conscious. Otherwise, that has no importance: a man's failures imply judgment, not of circumstances, but of himself.

The deepest and most organic death is death in solitude, when even light becomes a principle of death. In such moments you will be severed from life, from love, smiles, friends and even from death. And you will ask yourself if there is anything besides the nothingness of the world and your own nothingness.

Bad times, hard times, this is what people keep saying; but let us live well, and times shall be good. We are the times: Such as we are, such are the times.

The conception of the necessary unit of all that is resolves itself into the poverty of the imagination, and a freer logic emancipates us from the straitwaistcoated benevolent institution which idealism palms off as the totality of being.

But he, with these burthens on him, planned, commenced, and completed, the History of India; and this in the course of about ten years, a shorter time than has been occupied (even by writers who had no other employment) in the production of almost any other historical work of equal bulk, and of anything approaching to the same amount of reading and research. And to this is to be added, that during the whole period, a considerable part of almost every day was employed in the instruction of his children: in the case of one of whom, myself, he exerted an amount of labour, care, and perseverance rarely, if ever, employed for a similar purpose, in endeavouring to give, according to his own conception, the highest order of intellectual education.

In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating quality of the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions.

To choose one sock from each of infinitely many pairs of socks requires the Axiom of Choice, but for shoes the Axiom is not needed.

The benefit of the governed is made to lie on one side and the benefit of the governors on the other.

Newton... (after having remarked that geometry only requires two of the mechanical actions which it postulates, namely, to describe a straight line and a circle) says: geometry is proud of being able to achieve so much while taking so little from extraneous sources. One might say of metaphysics, on the other hand: it stands astonished, that with so much offered it by pure mathematics it can effect so little. In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter.

Not to be absolutely certain is, I think, one of the essential things in rationality. 

It is remarkable that among all the preachers there are so few moral teachers. The prophets are employed in excusing the ways of men.

It is too narrow an understanding of production which confines it merely to the making of things. Production includes not merely the making of things, but the bringing of them to the consumer. The merchant or storekeeper is thus as truly a producer as is the manufacturer, or farmer, and his stock or capital is as much devoted to production as is theirs.

There is no nature which is inferior to art, the arts imitate the nature of things.

But such is the nature of the human mind, that it always lays hold on every mind that approaches it; and as it is wonderfully fortified by an unanimity of sentiments, so is it shocked and disturbed by any contrariety. Hence the eagerness, which most people discover in a dispute; and hence their impatience of opposition, even in the most speculative and indifferent opinions.

In default of any other proof, the thumb would convince me of the existence of a God.

Good music is very close to primitive language.

That which Fortune has not given, she cannot take away.

It makes unavoidably necessary an entirely new organization of society in which production is no longer directed by mutually competing individual industrialists but rather by the whole society operating according to a definite plan and taking account of the needs of all.

None of the things they learn, should ever be made a burthen to them, or impos's on them as a task. Whatever is so proposed, presently becomes irksome; the mind takes an aversion to it, though before it were a thing of delight or indifferency. Let a child but be ordered to whip his top at a certain time every day, whether he has or has not a mind to it; let this be but requir'd of him as a duty, wherein he must spend so many hours morning and afternoon, and see whether he will not soon be weary of any play at this rate. Is it not so with grown men?

I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. I am the good shepherd: the good shepherd giveth his life for the sheep.

We are living even now among punishments and ruins.

Truth happens to an idea. It becomes true, is made true by events. Its verity is in fact an event, a process: the process namely of its verifying itself, its veri-fication. Its validity is the process of its valid-ation.

The symptom is not only a cyphered message, it is at the same time a way for the subject to organize his enjoyment - that is why, even after the completed interpretation, the subject is not prepared to renounce his symptom.

The principle of brotherhood expounded by the agitator of Nazareth preserved the germ of life, of truth and justice, so long as it was the beacon light of the few. The moment the majority seized upon it, that great principle became a shibboleth and harbinger of blood and fire, spreading suffering and disaster. The attack on the omnipotence of Rome was like a sunrise amid the darkness of the night, only so long as it was made by the colossal figures of a Huss, a Calvin, or a Luther. Yet when the mass joined in the procession against the Catholic monster, it was no less cruel, no less bloodthirsty than its enemy. Woe to the heretics, to the minority, who would not bow to its dicta. After infinite zeal, endurance, and sacrifice, the human mind is at last free from the religious phantom; the minority has gone on in pursuit of new conquests, and the majority is lagging behind, handicapped by truth grown false with age.

Indeed, history is nothing more than a tableau of crimes and misfortunes.

Whatever limits us we call Fate.
