However, all these do commonly agree in this one thing, in supposing virtue to be a certain disposition and faculty of the governing and directive part of the soul, of which reason is the cause; or rather to be reason itself, when it consents to what it ought, and is firm and immutable. And they do likewise think, that that part of the soul which is the seat of the passions, and is called brutal or irrational, is not at all distinct by any physical difference from that which is rational; but that this part of the soul (which they call rational and directive), being wholly turned about and changed by its affections and by those several alterations which are wrought in it with respect either to habit or disposition, becometh either vice or virtue, without having any thing in itself that is really brutal or irrational, but is then called brutal or irrational, when by the over-ruling and prevailing violence of our appetites it is hurried on to something absurd and vicious, against the judgment of reason. For passion, according to them, is nothing else but depraved and intemperate reason, that through a perverse and vicious judgment is grown over-vehement and headstrong.
