Fire in the sky

“The things I feared were not in the sky, but in the nature and in the touch of humanity. The cruelty of children ... the blindness of the unpitiful - these were my terrors. But not the crash of thunder overhead, not the bolts of fire from the clouds.”
(Ellen Glasgow).

“How many centuries must have elapsed before men reached the point of seeing any other fire than that in the sky?”
(Jean-Jacques Rousseau).
