The psychic extensions of security from antique stoicism to neoliberal resilience : the “unconscious slave” as an adaptation technology. Vulnerability (from Latin vulnerare, to injure) refers to a degree of weakening that reduces the reserve of capacities accumulated by a human that are essential to resist stimuli and environmental aggression. Neoliberal globalization accelerates the cascading multiplication of destabilizing events and difficult living conditions, consisting of economic precariousness, social deprivation, ecological and health crises produced in series and experienced daily by populations. Under these conditions, resilience consists of a command followed by everyone and signing the end of their commitment in the world ; it is above all the obligation to resign themselves to their current state. However, this capacity to bounce back in force, to keep functioning by absorbing the shock in order to renew and adapt, can be found in antiquity with the Stoic doctrine, a technique for teaching a “slave morality” transformed into a lasting psychological disposition.
