ripens into maturity. It never acquires a sensory faculty ; never, that is, develops into 

 an animal. Still it is capable of growth up to a certain point, as the wind-eggs of birds 

 testify, so that some share in the nutritive faculty must be allowed to come from the 

 mother (Z>. G. ii. 5, 3). Such an egg then, if regarded as the conception of a plant, 

 is perfect; but, if regarded as the conception of an animal, is imperfect [D. G. iii. 7, 8). 

 The other faculties than the nutritive only appear in the fecundated germ. They are 

 imparted, then, to the germ m the fertilising fluid of the male parent. But how does this 

 fecundating fluid come to possess them ? Does it get them from the male organism, from 

 which it issues itself, or from some external source ? As regards the Sensory, the Motor, 

 and all other faculties than the Intellectual, they must necessarily come from the father ; 

 for they are inseparable from bodily "matter, there being no such thing as Sensation and 

 Motion without sensory and motor organs, and the matter of the fecundating fluid is 

 evidently all derived from the father's body. But as regards the higher faculty, or 

 Intellect, the case is otherwise^ This requires no bodily substance in which to be 

 incorporate. It exists independently of tangible matter ; and so may, and in fact does, 

 come into the fecundating fluid not from the father's body but from wlthou^> viz. from 

 the divine soul of the Cosmos. Thus the mother furnishes the material of the body 

 and, in some degree at least, the Nutritive faculty. The father contributes the Sensory 

 and the Motor faculties. While the Intellect comes from the soul of the Cosmos, and 

 is only transmitted by the father interrnediately.

16. The Soul is the source of vital motion, and the several psychical modes correspond, 

 though not always as the active source, to the several modes of motion. Of these there 

 are three (Phys. v. 2, 8). Firstly motion leading to change of bulk, i.e. growth and decay 

 (o<;{7/(r/s and <pdlffis) ; with this is associated the Nutritive and Genetic faculty, as the 

 active cause. Secondly motion with change of quality (ctAAJiojo-iy), of which sensation is 

 a form {D. A. ii. 4, 8) ; with this is associated the Sensory faculty, no longer however as 

 the active source, but as the passive recipient of the motion which starts from the objects 

 of sense. Thirdly motion with change of place {ipopi.) ; with this is associated the 

 Motor faculty of the 'soul, here again not passive but active. 



17. Cf. Metaph. v. i, 7. "The natural philosopher has to deal with the soul, so far 

 as it is inseparably united with matter," i.e. with all the soul, excepting the active 

 intellect, which is independent of the body and separable from it {D. G. ii. 3, 10 ; 

 D. A. ii. 2, 10). The consideration of this element of the soul belongs to "the first 

 philosophy " or metaphysics. It is, I presume, of the separable intellect that A. speaks, 

 when he compares the relation of soul and body to that of rower and boat (£>.A. ii. I, 12); 

 and of the inseparable faculties, when he takes for his simile the relation of vision to the 

 eye, or of the impression to wax (D. A, ii. i, 7 — ^9). 



18. The argument seems to be as follows: "Moreover that part of the soul which is 

 independent of matter cannot come within the province of natural science ; for this deals 

 only with the works of nature, and these are not abstractions but actual bodies, 

 concretions of form and matter, for" by such alone can the ends of nature, viz. the 

 activities of life, be fulfilled. [Natural Science then is concerned with that soul only 

 which is incorporate in matter.] For that there is such a soul, or nature, informing the 

 body, and that to it, and not to blind chance, are due the evolution and activities of 

 organisms, is shown by the constancy of the phenomena they present and by the fact 

 that the result of their evolutional processes is predictable with certainty." 



19. Both art and nature are concerned with concrete bodies in which form and matter 

 are combined ; but in the case of art the form is impressed on the matter from without.
