 Plotinus criticizes the Stoics because, on their theory, humans and their minds are parts of god, and god works his will through human actions. Plotinus believes that, if this were true, our decisions would be caused by something outside of ourselves and would not really be our own—we would not be agents any more than our feet are, when we use them to kick something. (The Stoics would reply that humans both move themselves and are moved by god through fate.) Furthermore, the Stoics’ theory has the unacceptable result of making god the cause of evil, when humans act wrongly (Enn. III.1[3].4). Instead, says Plotinus, we should hold that human minds are genuinely separate things, and that they are self-movers, the cause of their own thoughts and decisions (Enn. III.1[3].4, III.1[3].8, III.2[47].7). Here, Plotinus again follows Plato, who in his creation-myth the Timaeus asserts that human souls are distinct from the world-soul that animates the cosmos (Tim. 41d).
