Final answer:
Temperance is one of the six core virtues identified by positive psychology that contributes to human thriving, focusing on self-control and moderation.
Step-by-step explanation:
Research in the field of positive psychology has identified six core virtues that contribute to human thriving. One of these is temperance. This virtue, as also discussed by ancient philosophers like Aristotle and the Stoics, is about self-control and moderation. The Stoics, in particular, emphasized rational self-control and were wary of the false judgments and loss of control associated with strong emotions. Temperance, as a virtue, is therefore aligned with the Stoic value of maintaining inner freedom through rational self-regulation and is seen as necessary to a flourishing life. In contrast, competitiveness, individualism, and zeal, while they can have positive aspects, are not classified among the core virtues that lead to human thriving according to positive psychology.
