The physical change in the thickness of walls since the Middle Ages could be shown in a diagram. In the fourteenth century each house was a fortress. Man spent the major portion of his day in them, in secret and well-defended solitude. That solitude, working on the soul hour after hour, forged it, like a transcendent blacksmith, into a compact and forceful character. Under its treatment, man consolidated his individual destiny and sallied forth with impunity, never yielding to the contamination from the public. It is only in isolation that we gain, almost automatically, a certain discrimination in ideas, desires, longings, that we learn which are ours, and which are anonymous, floating in the air, falling on us like dust in the street.

Whether, then, all ought not immediately to discontinue and renounce it, with grief and abhorrence? Should not every society bear testimony against it, and account obstinate persisters in it bad men, enemies to their country, and exclude them from fellowship; as they often do for much lesser faults?

Wherever you encounter truth, look upon it as Christianity.

Do not ask who started it.

It is not my aim to surprise or shock you - but the simplest way I can summarize is to say that there are now in the world machines that think, that learn and that create. Moreover, their ability to do these things is going to increase rapidly until - in a visible future - the range of problems they can handle will be coextensive with the range to which the human mind has been applied.

Man's being is made of such strange stuff as to be partly akin to nature and partly not, at once natural and extranatural, a kind of ontological centaur, half immersed in nature, half transcending it.

Those least responsible for climate change are worst affected by it.

Though it is often assumed that naturalism must be hostile to religion, the opposite is true. Enemies of religion think of it as an intellectual error, which humanity will eventually grow out of. It is hard to square this view with Darwinian science - why should religion be practically universal, if it has no evolutionary value?

They have been spoken by Plato, spoken by Zeno, spoken by Chrysippus or by Posidonius, and by a whole host of Stoics as numerous as excellent. I shall show you how men can prove their words to be their own: it is by doing what they have been talking about.

Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.

A man really writes for an audience of about ten persons. Of course if others like it, that is clear gain. But if those ten are satisfied, he is content.

"You're a gentleman," they used to say to him. "You shouldn't have gone murdering people with a hatchet; that's no occupation for a gentleman."

For many, as Cranton tells us, and those very wise men, not now but long ago, have deplored the condition of human nature, esteeming life a punishment, and to be born a man the highest pitch of calamity; this, Aristotle tells us, Silenus declared when he was brought captive to Midas.

Rules for Demonstrations. I. Not to undertake to demonstrate any thing that is so evident of itself that nothing can be given that is clearer to prove it. II. To prove all propositions at all obscure, and to employ in their proof only very evident maxims or propositions already admitted or demonstrated. III. To always mentally substitute definitions in the place of things defined, in order not to be misled by the ambiguity of terms which have been restricted by definitions.

Aging people should know that their lives are not mounting and unfolding but that an inexorable inner process forces the contraction of life. For a young person it is almost a sin - and certainly a danger - to be too much occupied with himself; but for the aging person it is a duty and a necessity to give serious attention to himself.

Happiness is a matter of one's most ordinary everyday mode of consciousness being busy and lively and unconcerned with self. To be damned is for one's ordinary everyday mode of consciousness to be unremitting agonising preoccupation with self.

It has been said that love robs those who have it of their wit, and gives it to those who have none.

Happiness is a good flow of life. 

The mind must be indulged, and leisure must be given from time to time, which is the place of food and strength.

If we would regain our freedom, we must shake off the burden of sensation, no longer react to the world by our senses, break our bonds. For all sensation is a bond, pleasure as much as pain, joy as much as misery. The only free mind is the one that, pure of all intimacy with beings or objects, plies its own vacuity.

Difficulty is a severe instructor, set over us by the supreme ordinance of a parental Guardian and Legislator, who knows us better than we know ourselves, as he loves us better too. Pater ipse colendi haud facilem esse viam voluit. He that wrestles with us strengthens our nerves, and sharpens our skill. Our antagonist is our helper.

Not to be a proud and haughty person, you have to follow the old proverb and "know thyself." That is to say, you must regard your special talents, whatever beauty or fame you have, as gifts from God, and not as things you earned for yourself. Whatever is low and mean is not God's doing, however. Here you can only blame yourself. Remember the squalor of your birth and how naked and poor you were when you crawled into the light of day like a little animal.

A harmonious being cannot believe in God. Saints, criminals, and paupers have launched him, making him available to all unhappy people.

Is it not altogether absurd that, under actual circumstances, the average man does not feel spontaneously, and without being preached at, an ardent enthusiasm for those sciences and the related ones of biology?... Every day furnishes a new invention which this average man utilises. Every day produces a new anesthetic or vaccine from which this average man benefits. ... How is it, nevertheless, that there is no sign of the masses imposing on themselves any sacrifice of money or attention in order to endow science more worthily? Far from this being the case, the post-war period has converted the man of science into a new social pariah.

IF the passions and characters of man were not subject, like the material kingdoms, to distribution in series of groups, man would be out of unity with the universe; there would be duplicity of system in creation, and incoherence between the material and the passional worlds. If man would attain to social uniy, he should seek for the means in the serial order, to which God has subject all nature.

The believing man hath the Holy Ghost; and where the Holy Ghost dwelleth, He will not suffer a man to be idle, butstirreth him up to all exercises of piety and godliness, and of true religion, to the love of God, to the patient suffering of afflictions, to prayer, to thanksgiving, and the exercise of charity towards all men.

Physiology does not teach us how to digest, nor logic how to discourse, nor esthetics how to feel beauty or express it, nor ethics how to be good. And indeed it is well if they do not teach us how to be hypocrites; for pedantry, whether it be pedantry of logic, or of esthetics, or of ethics, is at bottom nothing but hypocrisy.

If the injustice is part of the necessary friction of the machine of government, let it go, let it go; perchance it will wear smooth--certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself, then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then I say, break the law. Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.

If it is pleasing to observe in nature her desire to paint God in all his works, in which we see some traces of him because they are his images, how much more just is it to consider in the productions of minds the efforts which they make to imitate the essential truth, even in shunning it, and to remark wherein they attain it and wherein they wander from it, as I have endeavored to do in this study.

While moral rules may be propounded by authority the fact that these were so propounded would not validate them.

I construct my memories with my present. I am lost, abandoned in the present. I try in vain to rejoin the past: I cannot escape.

The world of immediate experience-the world in which we find ourselves living-must be comprehended, transformed, even subverted in order to become that which it really is.

What is the Jew?...What kind of unique creature is this whom all the rulers of all the nations of the world have disgraced and crushed and expelled and destroyed; persecuted, burned and drowned, and who, despite their anger and their fury, continues to live and to flourish. What is this Jew whom they have never succeeded in enticing with all the enticements in the world, whose oppressors and persecutors only suggested that he deny (and disown) his religion and cast aside the faithfulness of his ancestors?! The Jew - is the symbol of eternity. ... He is the one who for so long had guarded the prophetic message and transmitted it to all mankind. A people such as this can never disappear. The Jew is eternal. He is the embodiment of eternity.

Even serious students are misled by the myth of the subject.

Jesus said to His disciples, "Compare me to someone and tell Me whom I am like." Simon Peter said to Him, "You are like a righteous angel." Matthew said to Him, "You are like a wise philosopher." Thomas said to Him, "Master, my mouth is wholly incapable of saying whom You are like." Jesus said, "I am not your master. Because you have drunk, you have become intoxicated by the bubbling spring which I have measured out." And He took him and withdrew and told him three things. When Thomas returned to his companions, they asked him, "What did Jesus say to you?" Thomas said to them, "If I tell you one of the things which he told me, you will pick up stones and throw them at me; a fire will come out of the stones and burn you up."

Mass man is a phenomenon of electric speed, not of physical quantity.

The spectacle of what religions have been in the past, of what certain religions still are to-day, is indeed humiliating for human intelligence. What a farrago of error and folly!'

Basically-I speak of life as it is and not of abstract philosophical constructs-life is only bearable because one does not go to the end; doing something is only possible when one has particular illusions and that holds also for friendships, for everything.

We live together, we act on, and react to, one another; but always and in all circumstances we are by ourselves. The martyrs go hand in hand into the arena; they are crucified alone. Embraced, the lovers desperately try to fuse their insulated ecstacies into a single self-transcendence; in vain. By its very nature every embodied spirit is doomed to suffer and enjoy in solitude.

I have come across men of letters who have written history without taking part in public affairs, and politicians who have concerned themselves with producing events without thinking about them. I have observed that the first are always inclined to find general causes whereas the second, living in the midst of disconnected daily facts, are prone to imagine that everything is attributable to particular incidents, and that the wires they pull are the same as those that move the world. It is to be presumed that both are equally deceived.

Those who purge the soul believe that the soul can receive no benefit from any teachings offered to it until someone by cross-questioning reduces him who is cross-questioned to an attitude of modesty, by removing the opinions that obstruct the teachings, and thus purges him and makes him think that he knows only what he knows, and no more.

If man puts his honor first in relying upon himself, knowing himself and applying himself, this in self-reliance, self-assertion, and freedom, he then strives to rid himself of the ignorance which makes a strange impenetrable object a barrier and a hindrance to his self-knowledge.

One crime has to be concealed by another.

The wise man is joyful, happy and calm, unshaken, he lives on a plane with the gods.

Art is naturally concerned with man in his existential aspect, not in his scientific aspect. For the scientist, questions about man's stature and significance, suffering and power, are not really scientific questions; consequently he is inclined to regard art as an inferior recreation. Unfortunately, the artist has come to accept the scientist's view of himself. The result, I contend, is that art in the twentieth century - literary art in particular - has ceased to take itself seriously as the primary instrument of existential philosophy. It has ceased to regard itself as an instrument for probing questions of human significance. Art is the science of human destiny. Science is the attempt to discern the order that underlies the chaos of nature; art is the attempt to discern the order that underlies the chaos of man. At its best, it evokes unifying emotions; it makes the reader see the world momentarily as a unity.
