The mass of men serve the state thus, not as men mainly, but as machines, with their bodies. They are the standing army, and the militia, jailers, constables, posse comitatus, etc. In most cases there is no free exercise whatever of the judgement or of the moral sense; but they put themselves on a level with wood and earth and stones; and wooden men can perhaps be manufactured that will serve the purpose as well. Such command no more respect than men of straw or a lump of dirt. They have the same sort of worth only as horses and dogs. Yet such as these even are commonly esteemed good citizens. Others - as most legislators, politicians, lawyers, ministers, and office-holders - serve the state chiefly with their heads; and, as they rarely make any moral distinctions, they are as likely to serve the devil, without intending it, as god. A very few - as heroes, patriots, martyrs, reformers in the great sense, and men - serve the state with their consciences also, and so necessarily resist it for the most part; and they are commonly treated as enemies by it.

He who gives himself entirely to his fellow men appears to them useless and selfish; but he who gives himself partially to them in pronounced a benefactor and philanthropist.
