Ne spissæ risum tollant impune coronæ.
Hor. Art. Poet. 379.
He that's unskilful will not toss a ball,
Nor run, nor wrestle, for he fears the fall;
He justly fears to meet deserv'd disgrace,
And that the ring will hiss the baffled ass.
Creech.
Thus the man of learning is often resigned, almost by his own consent, to languor and pain; and while in the prosecution of his studies he suffers the weariness of labour, is subject by his course of life to the maladies of idleness.
It was, perhaps, from the observation of this mischievous omission in those who are employed about intellectual objects, that Locke has, in his "System of Education," urged the necessity of a trade to men of all ranks and professions, that when the mind is weary with its proper task, it may be relaxed by a slighter attention to some mechanical operation; and that while the vital functions are resuscitated and awakened by vigorous motion, the understanding may be restrained from that vagrance and dissipation by which it relieves itself after a long intenseness of thought, unless some allurement be presented that may engage application without anxiety.
There is so little reason for expecting frequent conformity to Locke's precept, that it is not necessary to inquire whether the practice of mechanical arts might not give occasion to petty emulation, and degenerate ambition; and whether, if our divines and physicians were taught the lathe and the chisel, they would not think more of their tools than their books; as Nero neglected the care of his empire for his chariot and his fiddle. It is certainly dangerous to be too much pleased with little things; but what is there which may not be perverted? Let us remember how much worse employment might have been found for those hours, which a manual occupation appears to engross; let us compute the profit with the loss, and when we reflect how often a genius is allured from his studies, consider likewise that perhaps by the same attraction he is sometimes withheld from debauchery, or recalled from malice, from ambition, from envy, and from lust.
