The development of an idea is like the growth of the organism that produces it. It is neither spontaneous, instantaneous, nor in a continuous line of evolution. The first inception is in the observation of a fact. Through other observations and the elaboration of new thought it assumes its embryonic forms; at last the labor of some greater intellect delivers it from its enshrouding mysteries, and it becomes a self-sustaining, active power.
