Even for the sake of its hygienic influence the development of mechanical skill deserves more general encouragement. Crank-work gymnastics are apt to pall, but in pursuit of a favorite handicraft even an invalid can beguile himself into a good deal of health-giving exercise, and, besides, the versatile development of the muscular system reacts on the functions of the vital organs, and thus explains the robust health of active mechanics often laboring under the disadvantage of indoor confinement. The poet Goethe, whose intuitions of practical philosophy rival those of Bacon and Franklin, records the opinion that every brain-worker should have some mechanical by-trade in order to obviate one-sidedness, and mental as well as physical debility. Every handicraft reveals by-laws of Nature which no cyclopedia can teach an inquirer; manual labor is a school of practical wisdom, and sound “common sense,” as the English language happily expresses the sum of that wisdom, is a prerogative of farmers and mechanics far, far oftener than of speculative philosophers. Nor are such benefits limited to emergencies from which wealth could dispense its possessor. An amateur handicraft is the best safeguard against the chief bane of wealth: ennui, with its temptations to folly and vice. Nabobs can do worse than imitate the example of Carlo Boromeo, who spent every leisure hour of his philanthropic life in practical landscape gardening, and turned a large and once barren lake-island into the loveliest paradise of southern Europe. “Heroum filii noxae,” “the sons of the great are apt to be nuisances,” would be less true if Goethe’s advice were heeded by our fashionable educators, and the benefits of his plan would extend to emergencies for which fashionable accomplishments afford only a dubious safeguard. “A mechanical trade,” says Jean Jacques Rousseau, “is the best basis of safety against the caprices of fortune. Classical scholarship may go begging, where technical skill finds its immediate reward. A distressed savant may recover his loss in the course of years; a skilful mechanic need only enter the next workshop and show a sample of his handiwork. ‘Well, let’s see you try,’ the reply will be; ‘step this way and pitch in.’” Thus, too, gymnastic agility is the best safeguard against numberless perils. A mother who hopes to protect her boy by keeping him at home and guarding him from the rough sports of his playmates, forgets that her apron-strings cannot guide him through the perils of after years; and a better plan was that of Cato, the statesman, warrior, and philosopher, who, in the midst of his manifold duties, found time to instruct his young sons in leaping ditches, and swimming rapid rivers, in order to “teach them to overcome danger that could not be permanently avoided.” C.—PERVERSION.
