VII. Whether Our Soul is Rational.

That our soul is rational, one might demonstrate by many arguments. And first of all from the fact that it has discovered the arts that are for the service of our life. For no one could say that these arts were introduced casually and accidentally, as no one could prove them to be idle, and of no utility for our life. If, then, these arts contribute to what is profitable for our life, and if the profitable is commendable, and if the commendable is constituted by reason, and if these things are the discovery of the soul, it follows that our soul is rational.

Again, that our soul is rational, is also proved by the fact that our senses are not sufficient for the apprehension of things. For we are not competent for the knowledge of things by the simple application of the faculty of sensation. But as we do not choose to rest in these without inquiry,⁴⁵⁷⁴⁵⁷    ἐπεὶ μηδὲ στῆναι περὶ αὐτὰ θέλομεν. that proves that the senses, apart from reason, are felt to be incapable of discriminating between things which are identical in form and similar in colour, though quite distinct in their natures. If, therefore, the senses, apart from reason, give us a false conception of things, we have to consider whether things that are can be apprehended in reality or not. And if they can be apprehended, then the power which enables us to get at them is one different from, and superior to, the senses. And if they are not apprehended, it will not be possible for us at all to apprehend things which are different in their appearance from the reality. But that objects are apprehensible by us, is clear from the fact that we employ each in a way adaptable to utility, and again turn them to what we please. Consequently, if it has been shown that things which are can be apprehended by us, and if the senses, apart from reason, are an erroneous test of objects, it follows that the intellect⁴⁵⁸⁴⁵⁸    νοῦς. is what distinguishes all things in reason, and discerns things as they are in their actuality. But the intellect is just the rational portion of the soul, and consequently the soul is rational.

Finally, because we do nothing without having first marked it out for ourselves; and as that is nothing else than just the high prerogative⁴⁵⁹⁴⁵⁹    ἀξίωμα. [Elucidation II.] of the soul,—for its knowledge of things does not come to it from without, but it rather sets out these things, as it were, with the adornment of its own thoughts, and thus first pictures forth the object in itself, and only thereafter carries it out to actual fact,—and because the high prerogative of the soul is nothing else than the doing of all things with reason, in which respect it also differs from the senses, the soul has thereby been demonstrated to be rational.
