Damon Linker describes the composition of a purposeful life:
In the Aristotelian tradition of moral thinking, human beings don’t face a zero-sum choice between fulfillment and moral righteousness. They strive, instead, to fulfill a holistic vision of human flourishing that includes both happiness and nobility. Or rather, this vision of human flourishing treats happiness as inseparable from nobility. This is what Martin Seligman and the best of his colleagues in the positive psychology movement have in mind when they speak of the importance of “purpose” in a fulfilling human life.
A life spent in endless pursuit of egoistic self-satisfaction (Kant’s vision of corruption) would end in wretched desolation, but so would a life devoted purely to acts of exalted self-sacrifice (Kant’s moral ideal). A genuinely purposeful life, by contrast, is one in which an individual strives to become a good human being in the fullest sensecontented as much by work, career, and material reward as by devoting oneself to the flourishing of one’s children.
