It is true that I have sent six bullets through the head of my best friend, and yet I hope to show by this statement that I am not his murderer.

The basis of all true cosmic horror is violation of the order of nature, and the profoundest violations are always the least concrete and describable.

Almost nobody dances sober, unless they happen to be insane.

The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age.

I have looked upon all the universe has to hold of horror,and even the skies of spring and flowers of summer must ever afterward be poison to me.

If I am mad, it is mercy! May the gods pity the man who in his callousness can remain sane to the hideous end!

The human race will disappear. Other races will appear and disappear in turn. The sky will become icy and void, pierced by the feeble light of half-dead stars. Which will also disappear. Everything will disappear. And what human beings do is just as free of sense as the free motion of elementary particles. Good, evil, morality, feelings? Pure 'Victorian fictions'. Only egotism exists.
