The psychological construct of ‘generativity’ was introduced by Erik Erikson in Childhood and Society in 1950. This rich and complex notion encompasses the constellation of desires, concerns and commitments that motivate individuals and societies to pass on legacies to future generations. ‘Flourishing,’ which means, very roughly, living life well, is another rich and complex notion, interpretations of which are found in ancient philosophers such as Plato, Aristotle and the Stoics. In this article I relate interpretations of these two concepts by arguing that certain forms of generativity can be considered an Aristotelian-type virtue, and that the virtue of generativity is necessary, but not sufficient, for flourishing in the Aristotelian sense. In other words, one can be generative without flourishing. The reverse, however, does not seem true: it is hard to see how one can fully flourish without being generative.
