Here is an excerpt, quickly chosen, to illustrate the parts of the soul in Plato,
- At all levels of this plan can be found a three-step pattern consonant with the threefold structure of the soul introduced in the middle of the middle section of the "middle" discussion : a desiring, passionate, part (which is actually manifold), the epithumiai, which is the "reflection" in us of nature, phusis, matter, biology and the like ; a reasoning part, the logos, which makes it possible for us to get in touch with the intelligible, with order, with the "forms" outside time and space, with the divine ; and in between, an intermediate part, the thumos, akin to the will, the field of choice, judgment, decision-making and the like. *
How does this make in clear that head was an authority? It gives us the idea that for Plato reason resided in the head. It does not tell us that man should be the ruler of the wife.
