Puritan Indulgences.

"But there is no understanding the period of the Reformation in England until we have grasped the fact that the quarrel between the Puritans and the Papists was not primarily a quarrel between rigorism and indulgence, and that, in so far as it was, the rigorism was on the Roman side. On many questions, and specially in their view of the marriage bed, the Puritans were the indulgent party; if we may without disrespect so use the name of a great Roman Catholic, a great writer, and a great man, they were much more Chestertonian than their adversaries" (Lewis, Selected Literary Essays, p. 116).

The Murder of All Men.

"I put these things not in their mature logical sequence, but as they came: and this view was cleared and sharpened by an accident of the time. Under the lengthening shadow of Ibsen, an argument arose whether it was not a very nice thing to murder one's self. 
"Grave moderns told us that we must not even say 'poor fellow,' of a man who had blown his brains out, since he was an enviable person, and had only blown them out because of their exceptional excellence. Mr. William Archer even suggested that in the golden age there would be penny-in-the-slot machines, by which a man could kill himself for a penny. 
"In all this I found myself utterly hostile to many who called themselves liberal and humane. Not only is suicide a sin, it is the sin. It is the ultimate and absolute evil, the refusal to take an interest in existence; the refusal to take the oath of loyalty to life. The man who kills a man, kills a man. The man who kills himself, kills all men; as far as he is concerned he wipes out the world. His act is worse (symbolically considered) than any rape or dynamite outrage. For it destroys all buildings: it insults all women. The thief is satisfied with diamonds; but the suicide is not: that is his crime. He cannot be bribed, even by the blazing stones of the Celestial City. The thief compliments the things he steals, if not the owner of them. But the suicide insults everything on earth by not stealing it. He defiles every flower by refusing to live for its sake. There is not a tiny creature in the cosmos at whom his death is not a sneer. When a man hangs himself on a tree, the leaves might fall off in anger and the birds fly away in fury: for each has received a personal affront. 
"Of course there may be pathetic emotional excuses for the act. There often are for rape, and there almost always are for dynamite. But if it comes to clear ideas and the intelligent meaning of things, then there is much more rational and philosophic truth in the burial at the cross-roads and the stake driven through the body, than in Mr. Archer's suicidal automatic machines. There is a meaning in burying the suicide apart. The man's crime is different from other crimes—for it makes even crimes impossible" (Chesterton, Orthodoxy).

One of the Commonest Signs of a Rotter.

"Thoroughly worldly people never understand even the world; they rely altogether on a few cynical maxims which are not true. Once I remember walking with a prosperous publisher, who made a remark which I had often heard before; it is, indeed, almost a motto of the modern world. Yet I had heard it once too often, and I saw suddenly that there was nothing in it. The publisher said of somebody, 'That man will get on; he believes in himself.' 
"And I remember that as I lifted my head to listen, my eye caught an omnibus on which was written 'Hanwell.' I said to him, 'Shall I tell you where the men are who believe most in themselves? For I can tell you. I know of men who believe in themselves more colossally than Napoleon or Caesar. I know where flames the fixed star of certainty and success. I can guide you to the thrones of the Super-men. The men who really believe in themselves are all in lunatic asylums.'
"He said mildly that there were a good many men after all who believed in themselves and who were not in lunatic asylums. 'Yes, there are,' I retorted, 'and you of all men ought to know them. That drunken poet from whom you would not take a dreary tragedy, he believed in himself. That elderly minister with an epic from whom you were hiding in a back room, he believed in himself. If you consulted your business experience instead of your ugly individualistic philosophy, you would know that believing in himself is one of the commonest signs of a rotter. Actors who can't act believe in themselves; and debtors who won't pay. It would be much truer to say that a man will certainly fail, because he believes in himself. Complete self-confidence is not merely a sin; complete self-confidence is a weakness. Believing utterly in one's self is a hysterical and superstitious belief like believing in Joanna Southcote: the man who has it has "Hanwell" written on his face as plain as it is written on that omnibus.' 
"And to all this my friend the publisher made this very deep and effective reply, 'Well, if a man is not to believe in himself, in what is he to believe?' After a long pause I replied, 'I will go home and write a book in answer to that question.' This is the book that I have written in answer to it" (Chesterton, Orthodoxy).

Love is Bound.

"The devotee is entirely free to criticize; the fanatic can safely be a skeptic. Love is not blind—that is the last thing that it is. Love is bound. And the more that it is bound, the less it is blind" (Chesterton, Orthodoxy).

Evolution Really is Mistaken for Explanation.

"But this little incident has always lingered in my mind as a sort of parable. Most modern histories of mankind begin with the word evolution, and with a rather wordy exposition of evolution, for much the same reason that operated in this case. There is something slow and soothing and gradual about the word and even about the idea. As a matter of fact, it is not, touching these primary things, a very practical word or a very profitable idea. Nobody can imagine how nothing can turn into something. Nobody can get an inch nearer to it by explaining how something could turn into something else. It is really far more logical to start by saying ‘In the beginning God created heaven and earth’ even if you only mean ‘In the beginning some unthinkable power began some unthinkable process.’ For God is by its nature a name of mystery, and nobody ever supposed that man could imagine how a world was created any more than he could create one. But evolution really is mistaken for explanation. It has the fatal quality of leaving on many minds the impression that they do understand it and everything else; just as many of them live under a sort of illusion that they have read the Origin of Species" (Chesterton, The Everlasting Man).

Blasphemy is an Artistic Effect.

“Blasphemy is an artistic effect, because blasphemy depends upon a philosophical conviction. Blasphemy depends upon belief and is fading with it. If any one doubts this, let him sit down seriously and try to think blasphemous thoughts about Thor. I think his family will find him at the end of the day in a state of some exhaustion” (Chesterton, Heretics).

We Now Must Discuss in the Dark.

"Suppose that a great commotion arises in the street about something, let us say a lamp-post, which many influential persons desire to pull down.
"A grey-clad monk, who is the spirit of the Middle Ages, is approached upon the matter, and begins to say, in the arid manner of the Schoolmen, “Let us first of all consider, my brethren, the value of Light. If Light be in itself good–”
"At this point he is somewhat excusably knocked down.
"All the people make a rush for the lamp-post, the lamp-post is down in ten minutes, and they go about congratulating each other on their unmediaeval practicality. But as things go on they do not work out so easily.
"Some people have pulled the lamp-post down because they wanted the electric light; some because they wanted old iron; some because they wanted darkness, because their deeds were evil. Some thought it not enough of a lamp-post, some too much; some acted because they wanted to smash municipal machinery; some because they wanted to smash something.
"And there is war in the night, no man knowing whom he strikes. So, gradually and inevitably, to-day, to-morrow, or the next day, there comes back the conviction that the monk was right after all, and that all depends on what is the philosophy of Light.
"Only what we might have discussed under the gas-lamp, we now must discuss in the dark" (Chesterton, Heretics).

The Democracy of the Dead.

“Tradition means giving votes to the most obscure of all classes, our ancestors. It is the democracy of the dead. Tradition refuses to submit to that arrogant oligarchy who merely happen to be walking around” (Chesterton, Orthodoxy).
