A young person can no more have too much love of adventure than a mill can have too much water-power; only it needs to be worked, not wasted. Physical exercises give to energy and daring a legitimate channel, supply the place of war, gambling, licentiousness, highway-robbery, and office-seeking. De Quincey, in like manner, says that Wordsworth made pedestrianism a substitute for wine and spirits; and Emerson thinks the force of rude periods "can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war." The animal energy cannot and ought not to be suppressed; if debarred from its natural channel, it will force for itself unnatural ones. A vigorous life of the senses not only does not tend to sensuality in the objectionable sense, but it helps to avert it. Health finds joy in mere existence; daily breath and daily bread suffice. This innocent enjoyment lost, the normal desires seek abnormal satisfactions. The most brutal prize-fighter is compelled to recognize the connection between purity and vigor, and becomes virtuous when he goes into training, as the heroes of old observed chastity, in hopes of conquering at the Olympic Games. The very word _ascetic_ comes from a Greek word signifying the preparatory exercises of an athlete. There are spiritual diseases which coil poisonously among distorted instincts and disordered nerves, and one would be generally safer in standing sponsor for the soul of the gymnast than of the dyspeptic. Of course, the demand of our nature is not always for continuous exertion. One does not always seek that "rough exercise" which Sir John Sinclair asserts to be "the darling idol of the English." There are delicious languors, Neapolitan reposes, Creole siestas, "long days and solid banks of flowers." But it is the birthright of the man of the temperate zones to alternate these voluptuous delights with more heroic ones, and sweeten the reverie by the toil. So far as they go, the enjoyments of the healthy body are as innocent and as ardent as those of the soul. As there is no ground of comparison, so there is no ground of antagonism. How compare a sonata and a sea-bath or measure the Sistine Madonna against a gallop across country? The best thanksgiving for each is to enjoy the other also, and educate the mind to ampler nobleness. After all, the best verdict on athletic exercises was that of the great Sully, when he said, "I was always of the same opinion with Henry IV. concerning them: he often asserted that they were the most solid foundation, not only of discipline and other military virtues, but also of those noble sentiments and that elevation of mind which give one nature superiority over another."
