Remember that which pulls and hales you from one Passion to another, is no External Force, but your Fancy within you. There lies the Rhetorick that perswades you; That's the live Thing, and to speak plainly, that's the Man, after all. But when you talk of a Man, I would not have you tack Flesh and Blood to the Notion ; nor those Limbs neither which are made out on't : These are but Tools for the Soul to work with, and no more a part of a Man, than an Ax or a Plain, is a piece of a Carpenter : 'Tis true, Nature has glewed them together, and they grow as it were to the Soul, and there's all the Difference. But the use of them depends solely upon the Mind: 'Tis the Will that either checks, or sets them a going. They have but the Force of Instruments, and signify no more without foreign Direction, than a Shuttle, a Pen, or a Whip, which will neither Weave, nor Write, nor Lash the Horses, without some Body to manage them.
