All colors depend on _light_.

Light therefore ought previously to be examined; and with it its opposite, darkness.

With regard to light, to make it a cause capable of producing the sublime, it must be attended with some circumstances, besides its bare faculty of showing other objects.

Mere light is too common a thing to make a strong impression on the mind, and without a strong impression nothing can be sublime.

But such a light as that of the sun, immediately exerted on the eye, as it overpowers the sense, is a very great idea.
