"Trauma" is Greek for "wound." The world can wound our souls as well as our bodies, and some victims of psychological trauma never recover their equilibrium. Freud recognizes that we are vulnerable in this way ("vulnus" is Latin for "wound"), and has a theory of what happens. The Stoic Marcus Aurelius, by contrast, thinks we preserve an "inner citadel," a part of our soul that is invulnerable. The founder of CBT (Cognitive Behavioral Therapy) drew from Stoicism to develop a clinical method that promised to help people recover control of their minds. Jonathan Haidt and Greg Lukianoff adapt this Stoic approach to address recent movements in American higher-ed that would reformulate education for traumatized students.
