Stoicism as Applied Psychology

The revival of Stoicism in the past decade has been, on the whole, healthier than most philosophical revivals. This is partly because the tradition is unusually well-suited to being lifted out of its original context. Its central claims are not metaphysical in ways that require assent; they are psychological in ways that can be tested against experience.

The core Stoic move is the discipline of judgment: distinguishing what is up to us (our judgments, intentions, responses) from what is not (essentially everything else), and disciplining ourselves to invest emotional weight only in the former.

This is not a call to numbness. Marcus Aurelius, Epictetus and Seneca were not asking their readers to feel nothing. They were asking them to notice the moment at which a raw impression becomes an interpretation, and to hold that moment lightly enough to choose the interpretation with care.

Contemporary cognitive-behavioral therapy is, in significant part, a technical elaboration of exactly this practice. Aaron Beck acknowledged the debt. The results are among the most robust in clinical psychology. The Stoics were, in a real sense, running a two-thousand-year alpha test of a functioning applied psychology.
