The Hunterian law of _arrested development_ is not confined to vegetable and animal structure, but reaches the human intellect also. In the savage man, thought is infantile; and in the civilized, unequal, and ranging up and down a long scale. In the best races it is rare and imperfect. In happy moments it is reinforced, and carries out what were rude suggestions to larger scope, and to clear and grand conclusions. The poet cannot see a natural phenomenon which does not express to him a correspondent fact in his mental experience; he is made aware of a power to carry on and complete the metamorphosis of natural into spiritual facts. Everything which we hear for the first time was expected by the mind; the newest discovery was expected. In the mind we call this enlarged power Inspiration. I believe that nothing great and lasting can be done except by inspiration, by leaning on the secret augury. The man's insight and power are interrupted and occasional; he can see and do this or that cheap task at will, but it steads him not beyond. He is fain to make the ulterior step by mechanical means. It cannot so be done. That ulterior step is to be also by inspiration; if not through him, then by another man. Every real step is by what a poet called "lyrical glances," by lyrical facility, and never by main strength and ignorance. Years of mechanic toil will only seem to do it; it will not so be done. Inspiration is like yeast. 'Tis no matter in which of half a dozen ways you procure the infection; you can apply one or the other equally well to your purpose, and get your loaf of bread. And every earnest workman, in whatever kind, knows some favorable conditions for his task. When I wish to write on any topic, 'tis of no consequence what kind of book or man gives me a hint or a motion, nor how far off that is from my topic. Power is the first good. Rarey can tame a wild horse; but if he could give speed to a dull horse, were not that better? The toper finds, without asking, the road to the tavern, but the poet does not know the pitcher that holds his nectar. Every youth should know the way to prophecy as surely as the miller understands how to let on the water or the engineer the steam. A rush of thoughts is the only conceivable prosperity that can come to us. Fine clothes, equipages, villa, park, social consideration, cannot cover up real poverty and insignificance from my own eyes, or from others like mine.
