The only way out of today's misery is for people to become worthy of each other's trust.

If all things are in common among friends, the most precious is Wisdom. What can Juno give which thou canst not receive from Wisdom? What mayest thou admire in Venus which thou mayest not also contemplate in Wisdom? Her beauty is not small, for the lord of all things taketh delight in her. Her I have loved and diligently sought from my youth up.

They who have compared our lives to a dream were, perhaps, more in the right than they were aware of. When we dream, the soul lives, works, and exercises all its faculties, neither more nor less than when awake; but more largely and obscurely, yet not so much, neither, that the difference should be as great as betwixt night and the meridian brightness of the sun, but as betwixt night and shade; there she sleeps, here she slumbers; but, whether more or less, 'tis still dark, and Cimmerian darkness. We wake sleeping, and sleep waking.

Deniers do not get their views just from simple mistakes about language and truth. Rather, they believe that there is something to worry about in important areas of our thought and in traditional interpretations of those areas; they sense that it has something to do with truth; and (no doubt driven by the familiar desire to say something at once hugely general, deeply important, and reassuringly simple) they extend their worry to the notion of truth itself.

His imagination resembled the wings of an ostrich. It enabled him to run, though not to soar.

Live among men as if God beheld you; speak with God as if men were listening.

The metaphor is perhaps one of man's most fruitful potentialities. Its efficacy verges on magic, and it seems a tool for creation which God forgot inside one of His creatures when He made him. All our other faculties keep us within the realm of the real, of what is already there. The most we can do is to combine things or to break them up. The metaphor alone furnishes an escape; between the real things, it lets emerge imaginary reefs, a crop of floating islands. A strange thing, indeed, the existence in man of this mental activity which substitutes one thing for another - from an urge not so much to get at the first as to get rid of the second.

I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.

It is not how things are in the world that is mystical, but that it exists.

Hereby it is manifest, that during the time men live without a common Power to keep them all in awe, they are in that conditions called Warre; and such a warre, as is of every man, against every man.

Scaffolds, dungeons, jails flourish only in the shadow of a faith - of that need to believe which has infested the mind forever. The devil pales beside the man who owns a truth, his truth. We are unfair to a Nero, a Tiberius: it was not they who invented the concept heretic: they were only degenerate dreamers who happened to be entertained by massacres. The real criminals are men who establish an orthodoxy on the religious or political level, men who distinguish between the faithful and the schismatic.

We must now ask how changes of this sort can come about, considering first discoveries, or novelties of fact, and then inventions, or novelties of theory. That distinction between discovery and invention or between fact and theory will, however, immediately prove to be exceedingly artificial.

Language is a part of our organism and no less complicated than it.

A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause. If we seek the liberation of the people by means of a lie, we will surely grow confused, go astray, and lose sight of our objective, and if we have any influence at all on the people we will lead them astray as well - in other words, we will be acting in the spirit of reaction and to its benefit.

Impenetrable in their dissimulation, cruel in their vengeance, tenacious in their purposes, unscrupulous as to their methods, animated by profound and hidden hatred for the tyranny of man - it is as though there exists among them an ever-present conspiracy toward domination, a sort of alliance like that subsisting among the priests of every country.

We can't form our children on our own concepts; we must take them and love them as God gives them to us.

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.

What then? Shall I not follow in the footsteps of my predecessors? I shall indeed use the old road, but if I find one that makes a shorter cut and is smoother to travel, I shall open the new road. Men who have made these discoveries before us are not our masters, but our guides. Truth lies open for all; it has not yet been monopolized. And there is plenty of it left even for posterity to discover.

The panting breathless haste and vehemence of a man struggling in the thick of battle for life and salvation; this is the mood he is in!

Omnipresence has become an ordinary human dimension.

Only charity admitteth no excess. For so we see, aspiring to be like God in power, the angels transgressed and fell.

To teach virtue we must educate the emotions, and this means learning "what to feel" in the various circumstances that prompt them.

Who dismisses his adulterous wife and marries another woman, whereas his first wife still lives, remains perpetually in the state of adultery. Such a man does not any efficacious penance while he refuses to abandon the new wife. If he is a catechumen, he cannot be admitted to baptism, because his will remains rooted in the evil. If he is a (baptized) penitent, he cannot receive the (ecclesiastical) reconciliation as long as he does not break with his bad attitude.

For what avail the plough or sail, Or land or life, if freedom fail?

In order to acquire any exact and solid knowledge, the student must possess with perfect precision the ideas appropriate to that part of knowledge: and this precision is tested by the student's 'perceiving' the axiomatic evidence of the 'axioms' belonging to each 'Fundamental Idea'.

Religion in its humility restores man to his only dignity, the courage to live by grace.

Objectification is above all exteriorization, the alienation of spirit from itself.

If I had as clear an idea of ghosts, as I have of a triangle or a circle, I should not in the least hesitate to affirm that they had been created by God; but as the idea I possess of them is just like the ideas, which my imagination forms of harpies, gryphons, hydras, &c., I cannot consider them as anything but dreams, which differ from God as totally as that which is not differs from that which is.

Great ages of innovation are the ages in which entire cultures are junked or scrapped.

Whoever is versed in the jargon does not have to say what he thinks, does not even have to think it properly. The jargon takes over this task.

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

(Gardner) writes about various kinds of cranks with the conscious superiority of the scientist, and in most cases one can share his sense of the victory of reason. But after half a dozen chapters this non-stop superiority begins to irritate; you begin to wonder about the standards that make him so certain he is always right. He asserts that the scientist, unlike the crank, does his best to remain open-minded. So how can he be so sure that no sane person has ever seen a flying saucer, or used a dowsing rod to locate water? And that all the people he disagrees with are unbalanced fanatics? A colleague of the positivist philosopher A. J. Ayer once remarked wryly "I wish I was as certain of anything as he seems to be about everything." Martin Gardner produces the same feeling.

As the nature of the universal has given to every rational being all the powers that it has, so we have received from it this power also. For as the universal nature converts and fixes in its predestined place everything which stands in the way and opposes it, and makes such things a part of itself, so also the rational animal is able to make every hindrance its own material, and to use it for such purpose as it may have designed.

He who should teach men to die would at the same time teach them to live.

When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion.

There is another form of temptation, more complex in its peril. It originates in an appetite for knowledge. From this malady of curiosity are all those strange sights exhibited in the theatre. Hence do we proceed to search out the secret powers of nature (which is beside our end), which to know profits not, and wherein men desire nothing but to know.

No one should try to live if he has not completed his training as a victim.

One should hasten to put such witches to death. Statement of 20 August 1538;

My purpose is to set forth a very new science dealing with a very ancient subject. There is, in nature, perhaps nothing older than motion, concerning which the books written by philosophers are neither few nor small; nevertheless I have discovered by experiment some properties of it which are worth knowing and which have not hitherto been either observed or demonstrated. Some superficial observations have been made, as, for instance, that the free motion [naturalem motum] of a heavy falling body is continuously accelerated; but to just what extent this acceleration occurs has not yet been announced; for so far as I know, no one has yet pointed out that the distances traversed, during equal intervals of time, by a body falling from rest, stand to one another in the same ratio as the odd numbers beginning with unity.

We tend to believe the premises because we can see that their consequences are true, instead of believing the consequences because we know the premises to be true. But the inferring of premises from consequences is the essence of induction; thus the method in investigating the principles of mathematics is really an inductive method, and is substantially the same as the method of discovering general laws in any other science.

Things have no hold on the soul. They have no access to it, cannot move or direct it. It is moved and directed by itself alone. It takes the things before it and interprets them as it sees fit.

The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.

He who is not sure of his memory, should not undertake the trade of lying. 

It is, I think, safe to say that nothing was more alien to the minds of the scientists, who brought about the most radical and most rapid revolutionary process the world has ever seen, than any will to power. Nothing was more remote than any wish to 'conquer space' and to go to the moon. It was indeed their search for 'true reality' that led them to lose confidence in appearances, in the phenomena as they reveal themselves of their own accord to human sense and reason. They were inspired by an extraordinary love of harmony and lawfulness which taught them that they would have to step outside any merely given sequence or series of occurrences if they wanted to discover the overall beauty and order of the whole, that is, the universe.

To have accomplished nothing and to die overworked.

Survival machines that can simulate the future are one jump ahead of survival machines that who can only learn of the basis of trial and error. The trouble with overt trial is that it takes time and energy. The trouble with overt error is that it is often fatal. ...The evolution of the capacity to simulate seems to have culminated in subjective consciousness. Why this should have happened is, to me, the most profound mystery facing modern biology.

Never in the history of the world have there been so many migrants. And almost all of them are migrating from regions where nationality is weak or non-existent to the established nation states of the West. They are not migrating because they have discovered some previously dormant feeling of love or loyalty towards the nations in whose territory they seek a home. On the contrary, few of them identify their loyalties in national terms and almost none of them in terms of the nation where they settle. They are migrating in search of citizenship which is the principal gift of national jurisdictions, and the origin of the peace, law, stability and prosperity that still prevail in the West.

I die adoring God, loving my friends, not hating my enemies, and detesting superstition.
