Theophilus. The desire is not one property, but is in itself all the properties of nature; it is the ground in which they all dwell, and the mother out of which they are all born: so that all that is said of the three first forms of nature, is only so much said of three forms or properties of the desire. For the desire is not the first property of nature; but every property hath all that it hath in and from the desire. The first property of the desire, of that which is the peculiarity of its nature, as distinguished from the second, is, to compress, enclose, shut up., whence cometh thickness, darkness, hardness. But no sooner does the desire begin to compress, shut up, but it brings forth its own greatest enemy, and the highest resistance to itself: for it cannot compress or thicken, but by drawing or attracting; but drawing and attracting is quite contrary to shutting up, or compressing; because drawing or attracting is motion, and every motion is contrary to shutting up or compressing together.
