Chapter XIX.—The

Intellect Coeval with the Soul in the Human Being. An Example from

Aristotle Converted into Evidence Favourable to These Views.

Nor must we fail to notice those writers who

deprive the soul of the intellect even for a short period of time. They do this in order to prepare the way of introducing the intellect—and the mind also—at a subsequent time of life, even at the time when intelligence appears in a man. They maintain that the stage of infancy is supported by the soul alone, simply to promote vitality, without any intention of acquiring knowledge also, because not all things have knowledge which possess life. Trees, for instance, to quote Aristotle’s example, have vitality, but have not knowledge; and with him agrees every one who gives a share to all animated beings of the animal substance, which, according to our view, exists in man alone as his special property,—not because it is the work of God, which all other creatures are likewise, but because it is the breath of God, which this (human soul) alone is, which we say is born with the full equipment of its proper faculties. Well, let them meet us with the example of the trees: we will accept their challenge, (nor shall we find in it any detriment to our own argument;) for it is an undoubted fact, that whilst trees are yet but twigs and sprouts, and before they even reach the sapling stage, there is in them their own proper faculty of life, as soon as they spring out of their native beds. But then, as time goes on, the vigour of the tree slowly advances, as it grows and hardens into its woody trunk, until its mature age completes the condition which nature destines for it. Else what resources would trees possess in due course for the inoculation of grafts, and the formation of leaves, and the swelling of their buds, and the graceful shedding of their blossom, and the softening of their sap, were there not in them the quiet growth of the full provision of their nature, and the distribution of this life over all their branches for the accomplishment of their maturity? Trees, therefore, have ability or knowledge; and they derive it from whence they also derive vitality—that is, from the one source of vitality and knowledge which is peculiar to their nature, and that from the infancy which they, too, begin with. For I observe that even the vine, although yet tender and immature, still understands its own natural business, and strives to cling to some support, that, leaning on it, and lacing through it, it may so attain its growth. Indeed, without waiting for the husbandman’s training, without an espalier, without a prop, whatever its tendrils catch, it will fondly cling to, and embrace with really greater tenacity and force by its own inclination than by your volition. It longs and hastens to be secure. Take also ivy-plants, never mind how young: I observe their attempts from the very first to grasp objects above them, and outrunning everything else, to hang on to the highest thing, preferring as they do to spread over walls with their leafy web and woof rather than creep on the ground and be trodden under by every foot that likes to crush them. On the other hand, in the case of such trees as receive injury from contact with a building, how do they hang off as they grow and avoid what injures them! You can see that their branches were naturally meant to take the opposite direction, and can very well understand the vital instincts of such a tree from its avoidance of the wall. It is contented (if it be only a little shrub) with its own insignificant destiny, which it has in its foreseeing instinct thoroughly been aware of from its infancy, only it still fears even a ruined building. On my side, then, why should I not contend for these wise and sagacious natures of trees? Let them have vitality, as the philosophers permit it; but let them have knowledge too, although the philosophers disavow it.
