When a workman is unceasingly and exclusively engaged in the fabrication of one thing, he ultimately does his work with singular dexterity; but, at the same time, he loses the general faculty of applying his mind to the direction of the work. His every day becomes more of adroit and less industrious; so that it may be said of him, that, in proportion as the workman improves, the man is degraded. Alexis de Tocqueville
