 In the passage that may fairly be taken as the climax of Timaeus’ discourse (90a2–d7), human beings are urged to devote their utmost attention to the cultivation and preservation of the well being of their immortal, rational souls. The well being of a rational soul consists in its being well ordered (eu kekosmêmenon, 90c5), and so the goal of human life, given the fact that the soul’s revolutions were thrown off course around the time of birth (43a6–44b1), is to realign (exorthounta, 90d3) those revolutions with those of the universe at large. Such realignment is achieved by a study of the revolutions and harmonies of the universe and, once achieved, restores the soul to its original condition and thereby brings to fulfillment “that most excellent life offered to humankind by the gods, both now and forevermore” (90d5–7).
