Demons cannot know our souls or our thoughts.

Demons control all kinds of religions.

And when I say the world is governed by nothing but demons, who will continue to be demons until they have destroyed the world, I am not using profanities; on the contrary, demon is a scientific term, a formula covering a specific chemical composition without connotations from politics, religion, or moral philosophy . . . . Here among us on the lowest rung of the world of life, no attention is paid to books unless they are written by chemically analyzed demons, or at least for them. Poets and philosophers are respected in proportion to the contempt and disgust they feel for the creation of life. Give this day our daily war is the prayer of those who govern countries. Kill, kill, said the outlaw Skuggasveinn . . .

If demons existed, they would be the work of God; but would it he just on the part of God to have created beings condemned eternally to evil and to misery? If demons exist, it is in your low world, and in other worlds of similar degree that they are to be found. They are the human hypocrites who represent a just God as being cruel and vindictive, and who imagine that they make themselves agreeable to Him by the abominations they commit in His name.

Devils and demons have no objective existence. They have always represented, again, portions of mankind’s own psychological reality that to some extent he had not assimilated -- but in a schizophrenic kind of expression, projected instead outward from himself.

Demons are found where they act.

But you can't kill a demon because they're evil spirits, like a ghost.

I demòni non possono conoscere il futuro.

Monsters and demons are metaphors for the dark side of human nature. The irrational. The fanatical. The animal.

Listen, demons don’t exist And if they did exist they would look like Europeans. That must have been some kind of fish you saw or something.

the speed and energy of a demon, not an angel or superman as one would ardently hope for.

Angels and demons are beings completely devoid of any form of matter.

You want to know what it’s like to be a demon? Imagine knowing, always and forever, that you are right, and that everyone and everything else is wrong.

The more consciousness there is in such a sufferer who in despair wills to be himself, the more his despair intensifies and becomes demonic. It usually originates as follows. A self that in despair wills to be itself is pained in some distress or other that does not allow itself to be taken away from or separated from his concrete self. So now he makes precisely this torment the object of all his passion, and finally it becomes a demonic age. By now, even if God in heaven and all the angels offered to help him out of it- no, he does not want that, now it is too late. Once he would gladly have given everything to be rid of this agony, but he was kept waiting; now it is too late, now he would rather rage against everything and be the wronged victim of the whole world and of all life, and it is of particular significance to him to make sure that he has his torment on hand and that no one takes it away from him- for then he would not be able to demonstrate and prove to himself that he is right. This eventually becomes such a fixation that for an extremely strange reason he is afraid of eternity, afraid that it will separate him from his, demonically understood, infinite superiority over other men, his justification, demonically understood, for being what he is.
