It is so hard to forget what it is worse than useless to remember! If I am to be a thoroughfare, I prefer that it be of the mountain-brooks, the Parnassian streams, and not the town-sewers. There is inspiration, that gossip which comes to the ear of the attentive mind from the courts of heaven. There is the profane and stale revelation of the bar-room and the police court. The same ear is fitted to receive both communications. Only the character of the hearer determines to which it shall be open, and to which closed. I believe that the mind can be permanently profaned by the habit of attending to trivial things, so that all our thoughts shall be tinged with triviality.

In any race between human numbers and natural resources, time is against us.

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.

The most elementary form of rebellion, paradoxically, expresses an aspiration for order.

No man treats a motorcar as foolishly as he treats another human being. When the car will not go, he does not attribute its annoying behaviour to sin; he does not say, "You are a wicked motorcar, and I shall not give you any more petrol until you go." He attempts to find out what is wrong and to set it right. An analogous way of treating human beings is, however, considered to be contrary to the truths of our holy religion.

These people who have fled inward for their freedom also have to live outwardly, become visible, let themselves be seen; they are united with mankind through countless ties of blood, residence, education, fatherland, chance, the importunity of others; they are likewise presupposed to harbour countless opinions simply because these are the ruling opinions of the time; every gesture which is not clearly a denial counts as agreement.

If God has made us in his image, we have returned him the favor.

The less somebody knows and understands himself the less great he is, however great may be his talent. For this reason our scientists are not great.

It is high time that Communists should openly, in the face of the whole world, publish their views, their aims, their tendencies, and meet this nursery tale of the spectre of Communism with a Manifesto of the party itself.

Go where we will on the surface of things, men have been there before us.

It's not too much to say that every indication of Design in the Kosmos is evidence against the Omnipotence of the Designer. For what is meant by Design? Contrivance: the adaptation of means to an end. But the necessity for contrivance - the need of employing means - is a consequence of the limitation of power. Who would have recourse to means if to attain his end his mere word was sufficient? The very idea of means implies that the means have an efficacy which the direct action of the being who employs them has not. ...

[T]he philosophy of Plotinus has the defect of encouraging men to look within rather than to look without: when we look within we see nous, which is divine, while when we look without we see the imperfections of the sensible world. This kind of subjectivity was a gradual growth; it is to be found in the doctrines of Protagoras, Socrates, and Plato, as well as in the Stoics and Epicureans. But at first it was only doctrinal, not temperamental; for a long time it failed to kill scientific curiosity. [...] Plotinus is both an end and a beginning-an end as regards the Greeks, a beginning as regards Christendom.

Daughters of Time, the hypocritic Days, Muffled and dumb like barefoot dervishes, And marching single in an endless file, Bring diadems and fagots in their hands.

Again and again our foe, religion, has given birth to deeds sinful and unholy.

When profit diminishes, merchants are very apt to complain that trade decays; though the diminution of profit is the natural effect of its prosperity, or of a greater stock being employed in it than before.

An early morning walk is a blessing for the whole day.

When the imagination sleeps, words are emptied of their meaning: a deaf population absent-mindedly registers the condemnation of a man. ... there is no other solution but to speak out and show the obscenity hidden under the verbal cloak.

In brief, it is my thesis that human misery is the most urgent problem of a rational public policy and that happiness is not such a problem.

The Autarch maintained his indifferent calm, but a certain lack of certainty was gathering, and he did not like to experience a lack of certainty. He liked nothing which made him aware of limitations. An Autarch should have no limitations, and on Lingane he had none that natural law did not impose.

If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, the wish to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men. Great men may make great mistakes; and as the book tries to show, some of the greatest leaders of the past supported the perennial attack on freedom and reason. Their influence, too rarely challenged, continues to mislead those on whose defence civilization depends, and to divide them. The responsibility of this tragic and possibly fatal division becomes ours if we hesitate to be outspoken in our criticism of what admittedly is a part of our intellectual heritage. By reluctance to criticize some of it, we may help to destroy it all.

Granted that any practice causes more pain to animals than it gives pleasure to man; is that practice moral or immoral? And if, exactly in proportion as human beings raise their heads out of the slough of selfishness, they do not with one voice answer 'immoral,' let the morality of the principle of utility be for ever condemned.

You shall have joy, or you shall have power, said God; you shall not have both.

I'm afraid of losing my obscurity. Genuineness only thrives in the dark. Like celery.

The emotions I feel are no more meant to be shown in their unadulterated state than the inner organs by which we live.

You have heard that it was said to those of old, 'You shall not commit adultery.' But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. Exodus 20:14, Seventh Commandment Matthew 5:27-30 (NKJV)

Because of the way that myth takes it for granted that miracles are always happening, the waking life of a mythically inspired people the ancient Greeks, for instance more closely resembles a dream than it does the waking world of a scientifically disenchanted thinker.

Lucid intervals and happy pauses.

Tolerance and apathy are the last virtues of a dying society.

First of all, principles should be general. That is, it must be possible to formulate them without use of what would be intuitively recognized as proper names, or rigged definite descriptions.

First, what do we mean by anguish? The existentialist frankly states that man is in anguish. His meaning is as follows-When a man commits himself to anything, fully realizing that he is not only choosing what he will be, but is thereby at the same time a legislator deciding for the whole of mankind-in such a moment a man cannot escape from the sense of complete and profound responsibility.

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

Discord which appears at first to be a lamentable breach and dissolution of the unity of a party, is really the crowning proof of its success.

Christian Apocalyptic offers us no such hope. It does not even foretell, (which would be more tolerable to our habits of thought) a gradual decay. It foretells a sudden, violent end imposed from without; an extinguisher popped onto the candle, a brick flung at the gramophone, a curtain rung down on the play - "Halt!"

The third kind of life is the life of contemplation.

As there is a use in medicine for poisons, so the world cannot move without rogues.

But if we discard this definition of a people, and, assuming another, say that a people is an assemblage of reasonable beings bound together by a common agreement as to the objects of their love, then, in order to discover the character of any people, we have only to observe what they love. Yet whatever it loves, if only it is an assemblage of reasonable beings and not of beasts, and is bound together by an agreement as to the objects of love, it is reasonably called a people; and it will be a superior people in proportion as it is bound together by higher interests, inferior in proportion as it is bound together by lower.

We thus have a kind of see-saw: first, pure persuasion leading to the conversion of a minority; then force exerted to secure that the rest of the community shall be exposed to the right propaganda; and finally a genuine belief on the part of the great majority, which makes the use of force again unnecessary.

Superstition sets the whole world in flames; philosophy quenches them.

...it [is] possible to suppose that, if Russia is allowed to have peace, an amazing industrial development may take place, making Russia a rival of the United States.

For anyone who is alone, without God and without a master, the weight of days is dreadful. Hence one must choose a master, God being out of style.

It is absurd to excite reason against the primary postulates of pure time, as, for example, continuity, etc., since they follow from laws prior and superior to which nothing is found, and since reason herself in the use of the principle of contradiction cannot dispense with the support of this concept, so primitive and original is it.

[T]he very cannibalism of the counterrevolution will convince the nations that there is only one way in which the murderous death agonies of the old society and the bloody birth throes of the new society can be shortened, simplified and concentrated, and that way is revolutionary terror.

There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical.

The great affair, we always find, is to get money.

I have no patience with those who say that sexual excitement is shameful and that venereal stimuli have their origin not in nature, but in sin. Nothing is so far from the truth. As if marriage, whose function cannot be fulfilled without these incitements, did not rise above blame. In other living creatures, where do these incitements come from? From nature or from sin? From nature, of course. It must borne in mind that in the apetites of the body there is very little difference between man and other living creatures. Finally, we defile by our imagination what of its own nature is fair and holy. If we were willing to evaluate things not according to the opinion of the crowd, but according to nature itself, how is it less repulsive to eat, chew, digest, evacuate, and sleep after the fashion of dumb animals, than to enjoy lawful and permitted carnal relations?

To require that a so-called layman should not use his own reason in religious matters, particularly since religion is to be appreciated as moral, but instead follow the appointed clergyman and thus someone else's reason, is an unjust demand because as to morals every man must account for all his doings. The clergyman will not and even cannot assume such a responsibility.

A testimony is sufficient when it rests on: 1st. A great number of very sensible witnesses who agree in having seen well. 2d. Who are sane, bodily and mentally. 3d. Who are impartial and disinterested. 4th. Who unanimously agree. 5th. Who solemnly certify to the fact.

For I find that even those that have sought knowledge for itself and not for benefit, or ostentation, or any practical enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man, and quiet objections, than such causes as will direct him and give him light to new experiences and inventions.

The Calculus required continuity, and continuity was supposed to require the infinitely little; but nobody could discover what the infinitely little might be.

An authorship that began with Either/Or and advanced step by step seeks here its decisive place of rest, at the foot of the altar, where the author, personally most aware of his own imperfections and guilt, certainly does not call himself a truth-witness but only a singular kind of poet and thinker who, without authority, has had nothing new to bring but “has wanted once again to read through, if possible in a more inward way, the original text handed down from the fathers.
