After its own law and not by arithmetic is the rate of its progress to be computed. The soul’s advances are not made by gradation, such as can be represented by motion in a straight line; but rather by ascension of state, such as can be represented by metamorphosis,-from the egg to the worm, from the worm to the fly. The growths of genius are of a certain total character, that does not advance the elect individual first over John, then Adam, then Richard, and give to each the pain of discovered inferiority, but by every throe of growth the man expands there where he works, passing, at each pulsation, classes, populations of men. With each divine impulse the mind rends the thin rinds of the visible and finite, and comes out into eternity, and inspires and expires its air.
