The indocile liberty of this member is very remarkable, so importunately unruly in its tumidity and impatience, when we do not require it, and so unseasonably disobedient, when we stand most in need of it: so imperiously contesting in authority with the will, and with so much haughty obstinacy denying all solicitation, both of hand and mind. And yet, though his rebellion is so universally complained of, and that proof is thence deduced to condemn him, if he had, nevertheless, feed me to plead his cause, I should peradventure, bring the rest of his fellow-members into suspicion of complotting this mischief against him, out of pure envy at the importance and pleasure especial to his employment; and to have, by confederacy, armed the whole world against him, by malevolently charging him alone, with their common offence. For let any one consider, whether there is any one part of our bodies that does not often refuse to perform its office at the precept of the will, and that does not often exercise its function in defiance of her command. They have every one of them passions of their own, that rouse and awaken, stupefy and benumb them, without our leave or consent. How often do the involuntary motions of the countenance discover our inward thoughts, and betray our most private secrets to the bystanders. The same cause that animates this member, does also, without our knowledge, animate the lungs, pulse, and heart, the sight of a pleasing object imperceptibly diffusing a flame through all our parts, with a feverish motion. Is there nothing but these veins and muscles that swell and flag without the consent, not only of the will, but even of our knowledge also? We do not command our hairs to stand on end, nor our skin to shiver either with fear or desire; the hands often convey themselves to parts to which we do not direct them; the tongue will be interdict, and the voice congealed, when we know not how to help it.
