the present and its technological lures and discontents, thankfully, are not really [Susan Neiman‘s] concern, any more than the jeremiad is her chosen form; she comes across as a patient pedagogue rather than an angry scold. She sprinkles in a few musical references — to Lady Gaga and the Rolling Stones — and occasional nods to unspecified “studies.” In spite of these, “Why Grow Up?” isn’t an exercise in pop-culture polemics or pop-sociological cherry-picking. It’s a case for philosophy of an admirably old-fashioned kind. Neiman is less interested in “The Catcher in the Rye” than in “The Critique of Pure Reason,” and more apt to cite Hannah Arendt than Lena Dunham.
Nor, in spite of its subtitle, is her book a critique of contemporary mores. The “infantile age” she has in mind goes back to the 18th century, and its most important figures are Jean-Jacques Rousseau and Immanuel Kant. “Coming of age is an Enlightenment problem,” she writes, “and nothing shows so clearly that we are the Enlightenment’s heirs” than that we understand it as a topic for argument and analysis, as opposed to something that happens to everyone in more or less the same way. Before Kant and Rousseau, Neiman suggests, Western philosophy had little to say about the life cycle of individuals. As traditional religious and political modes of authority weakened, “the right form of human development became a philosophical problem, incorporating both psychological and political questions and giving them a normative thrust.”
