15. They who think the mind to be either a body or the combination or tempering of the body, will have all these things to seem to be in a subject, so that the substance is air, or fire, or some other corporeal thing, which they think to be the mind; but that the understanding (intelligentia) is in this corporeal thing as its quality, so that this corporeal thing is the subject, but the understanding is in the subject: viz. that the mind is the subject, which they judge to be a corporeal thing, but the understanding [intelligence], or any other of those things which we have mentioned as certain to us, is in that subject. They also hold nearly the same opinion who deny the mind itself to be body, but think it to be the combination or tempering together of the body; for there is this difference, that the former say that the mind itself is the substance, in which the understanding [intelligence] is, as in a subject; but the latter say that the mind itself is in a subject, viz. in the body, of which it is the combination or tempering together. And hence, by consequence, what else can they think, except that the understanding also is in the same body as in a subject?
