In Why Grow Up, Neiman explores the forces that are arrayed against maturity, and shows how philosophy can help us want to grow up. Travel, both literally and as a metaphor, has been seen as a crucial step to coming of age by thinkers as diverse as Kant, Rousseau, Hume and Simone de Beauvoir. Neiman discusses childhood, adolescence, sex, and culture, and asks how the idea of travel can help us build a model of maturity that makes growing up a good option and leaves space in our culture for grown-ups. Refuting the widespread belief that the best time of your life is the decade between sixteen and twenty-six, she argues that being grown-up is itself an ideal: one that is rarely achieved in its entirety, but all the more worth striving for.
