Adults need more complex narratives. They have their own narratives. The main characters are themselves.
We could speak about the meaning of life vis-a-vis non-consequential
deontological theories, apodictic transformation schemata, the incoherence of exemplification, metaphysical realism, Cartesian interactive dualism, revised non reductive dualism, postmodernist grammatology and dicey dichotomies. But we would still be left with Nietzsche's preposterous mustache which instills great anguish and skepticism in the brain, which leads (as it did in his case) to utter madness. I suggest we go to Paris instead.
