“The salvation of the world depends on the men who will not take evil good-humouredly, and whose laughter destroys the fool instead of encouraging him.”

Context: Take care that thou be not made a fool by flatterers, for even the wisest men are abused by these. Know, therefore, that flatterers are the worst kind of traitors; for they will strengthen thy imperfections, encourage thee in all evils, correct thee in nothing; but so shadow and paint all thy vices and follies, as thou shalt never, by their will, discern evil from good, or vice from virtue. And, because all men are apt to flatter themselves, to entertain the additions of other men's praises is most perilous. Do not therefore praise thyself, except thou wilt be counted a vain-glorious fool; neither take delight in the praises of other men, except thou deserve it, and receive it from such as are worthy and honest, and will withal warn thee of thy faults; for flatterers have never any virtue — they are ever base, creeping, cowardly persons. A flatterer is said to be a beast that biteth smiling: it is said by Isaiah in this manner — "My people, they that praise thee, seduce thee, and disorder the paths of thy feet;" and David desired God to cut out the tongue of a flatterer.
But it is hard to know them from friends, they are so obsequious and full of protestations; for as a wolf resembles a dog, so doth a flatterer a friend. A flatterer is compared to an ape, who, because she cannot defend the house like a dog, labour as an ox, or bear burdens as a horse, doth therefore yet play tricks and provoke laughter. Thou mayest be sure, that he that will in private tell thee thy faults is thy friend; for he adventures thy mislike, and doth hazard thy hatred; for there are few men that can endure it, every man for the most part delighting in self-praise, which is one of the most universal follies which bewitcheth mankind.

Context: No one can understand Communism who does not believe in the devil. The Communists believe in the devil. The Communists organized a so-called "patriotic" church. A few brain washed were to be in charge of the churches because they were loyal to the anti-God regime.
One of the first orders given by the Communists to them was that the prayer to Prayer to Saint Michael be no longer said because it invoked the protection of St. Michael against "the wickedness and snares of the devil." As one Communist judge said: "We are those devils."
It is hard for many in the free world to believe that there are not only bad men, but evil men. Bad men steal, rape, ravage and plunder. Evil men may not always do these things, but they seek to destroy goodness, virtue, morality, decency, truth and honor. Bad men who steal admit honesty; evil men who do not steal, call dishonesty "honesty," totalitarianism "democracy," slavery "freedom." Evil men can be nice at table, polite with women, courteous in Washington, refined in London and calm in Geneva.
But the principle which guides their every move is the maxim of Lenin: every lie, trickery, knavery and deceit must be used to.

Christ, Old Student in a New School (1972)
Context: That so much time was wasted in this pain.
Ten thousand years ago he might have let off down
To not return again!
A dreadful laugh at last escapes his lips;
The laughter sets him free.
A Fool lives in the Universe! he cries.
The Fool is me!
And with one final shake of laughter
Breaks his bonds.
The nails fall skittering to marble floors.
And Christ, knelt at the rail, sees miracle
As Man steps down in amiable wisdom
To give himself what no one else can give:
His liberty.

§ IV
1910s, At the Feet of the Master (1911)
Context: See what gossip does. It begins with evil thought, and that in itself is a crime. For in everyone and in everything there is good; in everyone and in everything there is evil. Either of these we can strengthen by thinking of it, and in this way we can help or hinder evolution; we can do the will of the Logos or we can resist Him. If you think of the evil in another, you are doing at the same time three wicked things:
(1) You are filling your neighbourhood with evil thought instead of with good thought, and so you are adding to the sorrow of the world.
(2) If there is in that man the evil which you think, you are strengthening it and feeding it; and so you are making your brother worse instead of better. But generally the evil is not there, and you have only fancied it; and then your wicked thought tempts your brother to do wrong, for if he is not yet perfect you may make him that which you have thought him.
(3) You fill your own mind with evil thoughts instead of good; and so you hinder your own growth, and make yourself, for those who can see, an ugly and painful object instead of a beautiful and lovable one.
Not content with having done all this harm to himself and to his victim, the gossip tries with all his might to make other men partners in his crime. Eagerly he tells his wicked tale to them, hoping that they will believe it; and then they join with him in pouring evil thought upon the poor sufferer. And this goes on day after day, and is done not by one man but by thousands. Do you begin to see how base, how terrible a sin this is? You must avoid it altogether.
