The human soul is a miniature analogue to the world soul, the animating principle of the cosmos. And its highest capability is intellect, or reason. Timaeus tells the company: "Now we ought to think of the most sovereign part of our soul as god's gift to us, given to be our guiding spirit. This, of course, is the type of soul that, as we maintain, resides in the top part of our bodies. It raises us up away from the earth and toward what is akin to us in heaven. In saying this, we speak absolutely correctly. For it is from heaven, the place from which our souls were originally born, that the divine part suspends our head, i.e., our root, and so keeps our whole body erect... And to the extent that human nature can partake of immortality, he can in no way fail to achieve this: constantly caring for his divine part as he does, keeping well-ordered the guiding spirit that lives within him, he must indeed be supremely happy. Now there is but one way to care for anything, and that is to provide for it the nourishment and the motions proper to it. And the motions that have an affinity to the divine part within us are the thoughts and revolutions of the universe."
