But to come back to poets and artists;--if they really are more prone to the abuse of stimulants,--and I fear that this is true, --the reason of it is only too clear. A man abandons himself to a fine frenzy, and the power which flows through him, as I once explained to you, makes him the medium of a great poem or a great picture. The creative action is not voluntary at all, but automatic; we can only put the mind into the proper attitude, and wait for the wind, that blows where it listeth, to breathe over it. Thus the true state of creative genius is allied to reverie, or dreaming. If mind and body were both healthy and had food enough and fair play, I doubt whether any men would be more temperate than the imaginative classes. But body and mind often flag,--perhaps they are ill-made to begin with, underfed with bread or ideas, overworked, or abused in some way. The automatic action, by which genius wrought its wonders, fails. There is only one thing which can rouse the machine; not will,--that cannot reach it; nothing but a ruinous agent, which hurries the wheels awhile and soon eats out the heart of the mechanism. The dreaming faculties are always the dangerous ones, because their mode of action can be imitated by artificial excitement; the reasoning ones are safe, because they imply continued voluntary effort. I think you will find it true, that, before any vice can fasten on a man, body, mind, or moral nature must be debilitated. The mosses and fungi gather on sickly trees, not thriving ones; and the odious parasites which fasten on the human frame choose that which is already enfeebled. Mr. Walker, the hygeian humorist, declared that he had such a healthy skin it was impossible for any impurity to stick to it, and maintained that it was an absurdity to wash a face which was of necessity always clean. I don't know how much fancy there was in this; but there is no fancy in saying that the lassitude of tired-out operatives, and the languor of imaginative natures in their periods of collapse, and the vacuity of minds untrained to labor and discipline, fit the soul and body for the germination of the seeds of intemperance. Whenever the wandering demon of Drunkenness finds a ship adrift, --no steady wind in its sails, no thoughtful pilot directing its course,--he steps on board, takes the helm, and steers straight for the maelstrom. --I wonder if you know the TERRIBLE SMILE? [The young fellow whom they call John winked very hard, and made a jocular remark, the sense of which seemed to depend on some double meaning of the word SMILE. The company was curious to know what I meant.]
