earthy from what is most predominant therein.”—­Cudworth, “Intell.  Syst.”  From the same source we extract the following:  “Wherefore these ancients say that impure souls after their departure out of this body wander here up and down for a certain space in their spirituous vaporous and airy body, appearing about sepulchres and haunting their former habitation.  For which cause there is great reason that we should take care of living well, as also of abstaining from a fouler and grosser diet; these Ancients telling us likewise that this spirituous body of ours being fouled and incrassated by evil diet, is apt to render the soul in this life also more obnoxious to the disturbances of passions.  They further add that there is something of the Plantal or Plastic life, also exercised by the soul, in those spirituous or airy bodies after death; they being nourished too, though not after the same manner, as those gross earthy bodies of ours are here, but by vapours, and that not by parts or organs, but throughout the whole of them (as sponges), they imbibing everywhere those vapours.  For which cause they who are wise will in this life also take care of using a thinner and dryer diet, that so that spirituous body (which we have also at this present time within our proper body) may not be clogged and incrassed, but attenuated.  Over and above which, those Ancients made use of catharms, or purgations to the same end and purpose also.  For as this earthy body is washed by water so is that spirituous body cleansed by cathartic vapours—­some of these vapours being nutritive, others purgative.  Moreover, these Ancients further declared concerning this spirituous body that it was not organized, but did the whole of it in every part throughout exercise all functions of sense, the soul hearing, seeing and perceiving all sensibles by it everywhere.  For which cause Aristotle himself affirmeth in his Metaphysics that there is properly but one sense and one Sensory.  He by this one sensory meaneth the spirit, or subtle airy body, in which the sensitive power doth all of it through the whole immediately apprehend all variety of sensibles.  And if it be demanded to how it comes to pass that this spirit becomes organized in sepulchres, and most commonly of human form, but sometimes in the forms of other animals, to this those Ancients replied that their appearing so frequently in human form proceeded from their being incrassated with evil diet, and then, as it were, stamped upon with the form of this exterior ambient body in which they are, as crystal is formed and coloured like to those things which it is fastened in, or reflects the image of them.  And that their having sometimes other different forms proceedeth from the phantastic power of the soul itself, which can at pleasure transform the spirituous body into any shape.  For being airy, when it is condensed and fixed, it becometh visible, and again invisible and vanishing out of sight when it is expanded and
