His metaphor of the three souls is inherently political, and is expressed in explicitly political language—so it is no surprise that his account of disease makes it an ethical or moral matter ( Timaios 72–73, 86–87). Plato holds that disease derives from three causes: (1) an imbalance of the elements, or (2) the production of corrupt residues or humors, or (3) the blockage of the movement of bodily air ( Timaios 81–86). The restoration of the ordered governance of the body is accomplished by the enforced functioning of its organs and members through diet and activity (and preferably not drugs: Timaios 87–91).
Aristotle, Metaphysics 1 [980a22]) Greek poets invoked divine Muses to guide their tale, and often began, as before the walls of Troy, in mid-stream. Neither Klio of history nor Ourania of astronomy has appeared for this work, but the story does begin in its middle, after the most-studied period of Greek science (up through Aristotle). Numerous works exist on the early philosophers who speculated about the natural world, as well as on Hippokrates, Plato, and Aristotle. The focus here is the era between Aristotle and the “late-antique” commentators on Aristotle, during which a wide variety of writings were composed, but no single synthesis was standard.
These notions were part of the common corpus and formed the basis of Hellenistic astronomy. But the problem remained—how exactly to explain the observed motions, some of which can seem quite irregular. In the early second century BCE, two provincial mathematicians, Apollonios of Pergê and Hipparchos of Nikaia, worked out a system by which, for the first time ever, the motions of all the planets could in principle be predicted, on the basis of a model which provided a picture of their motions. Moreover, this system allowed the prediction of the motions of the sun and moon (the actual prediction of the motions of the other wandering stars was not accomplished for several centuries).
