Thus, when we say nature, in the abstract, meaning physically, we should be understood as alluding to those general, uniform, absolute, consistent, and beautiful laws, which control and render harmonious, as a great whole, the entire action, affinities, and destinies of the universe; and when we say nature in the speciality, we would be understood to speak of the nature of a rock, of a tree, of air, fire, water, and land.

Again, in alluding to a moral nature in the abstract, we mean sin, and its weaknesses, its attractions, its deformities-in a word, its totality; while, on the other hand, when we use the term, in this sense, under the limits of a speciality, we confine its signification to the particular shades of natural qualities that mark the precise object named.

Let us illustrate our positions by a few brief examples.
"When we say 'Oh nature, how art thou glorious, sublime, instructive!'-- we mean that her laws emanate from a power of infinite intelligence and perfection; and when we say 'Oh nature, how art thou frail, vain and insufficient!' we mean that she is, after all, but a secondary quality, inferior to that which brought her into existence, for definite, limited, and, doubtless, useful purposes.

In these examples we treat the principle in the abstract.
"The examples of nature in the speciality will be more familiar, and, although in no degree more true, will be better understood by the generality of my auditors.

Especial nature, in the physical signification, is apparent to the senses, and is betrayed in the outward forms of things, through their force, magnitude, substance, and proportions, and, in its more mysterious properties, to examination, by their laws, harmony, and action.
