looks to externals, or rather it looks to colored body, but does not see itself, because sight itself is neither body nor that which is colored. Hence it does not revert to itself. Neither therefore is this the case with any other irrational nature. For neither does the phantasy project a type of itself, but of that which is sensible, as for instance of colored body. Nor does irrational appetite desire itself, but aspires after a certain object of desire, such as honor, or pleasure, or riches. It does not therefore move itself. But if some one, on seeing that brutes exert rational energies, should apprehend that these also participate of the first self-moved, and on this account possess a soul converted to itself, it may perhaps be granted to him that these also are rational natures, except that they are not so essentially, but according to participation, and this most obscure, just as the rational soul may be said to be intellectual according to participation, as always projecting common conceptions without distortion. It must however be observed, that the extreme are that which is capable of being perfectly separated, such as the rational form, and that which is perfectly inseparable, such as corporeal quality, and that in the middle of these nature subsists, which verges to the inseparable, having a small representation of the separable and the irrational soul, which verges to the separable; or it appears in a certain respect to subsist by itself, separate from a subject; so that it becomes doubtful whether it is self-motive, or alter-motive. For it contains an abundant vestige of self-motion, but not that which is true and converted to itself, and on this account perfectly separated from a subject. And the vegetable soul has in a certain respect a middle subsistence. On this account to some of the ancients it appeared to be a certain soul, but to others, nature.
