Sōphrosynē and Sophia

… any individual caught in the unrestrained play of the passions and the immediate, unreflective pursuit of gratification is incapable of the highest human activity, a life of reason—incapable, that is, of a life of reason in its practical dimension, but also, and importantly, in its theoretical dimension as well. Sōphrosynē, for instance, is a prerequisite of sophia. And reciprocally, in some sense sophia, or at least philosophia, which liberates the human being from the “flattery” and coercion of the passions, is a prerequisite for sōphrosynē. Plato and Aristotle both teach us that.
