“The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents.”*
In less words, Lovecraft is referring to the unknown. That is the thing which our minds cannot grasp, the thing which haunts our sub-conscious, not just on an individual-to-individual basis, but as a collective whole. There will always be something that makes someone crawl.
What unknown things does the universe hide?
Before I stop, I would like to encourage you to think for a moment.
Just think . . .
“We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far.”*
(Don’t think too hard.)
