Religion is still useful among the herd - that it helps their orderly conduct as nothing else could. The crude human animal is in-eradicably superstitious, and there is every biological reason why they should be. Take away his Christian god and saints, and he will worship something else.

In his house at R'lyeh, dead Cthulu waits dreaming

I have harnessed the shadows that stride from world to world to sow death and madness.

I was nearly unnerved at my proximity to a nameless thing at the bottom of a pit.

Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.

I am writing this under an appreciable mental strain, since by tonight I shall be no more. Penniless, and at the end of my supply of the drug which alone makes life endurable, I can bear the torture no longer; and shall cast myself from this garret window into the squalid street below.

I could not help feeling that they were evil things -- mountains of madness whose farther slopes looked out over some accursed ultimate abyss.
