From an essay I wrote four years ago recommending our attention to an idea in Hesse's The Glass Bead Game:
To imagine yourself as you might have been in another place and time is to practice the dialectic of sameness and difference in a way that enhances your self-understanding, your experience of the human lifeworld, without risking damage to a neighbor. As I argue in my book Breaking Bread with the Dead, one of Thomas Pynchon’s characters was right to say that “personal density is proportionate to temporal bandwidth,” and reading works of the past is an excellent way to increase that bandwidth without suffering from the tensions associated with projects like John Howard Griffin’s. But to imagine yourself into another life can be a powerful application of the argument I make there, and I am tempted to argue that the writing of a Castalia-style Life would make an excellent senior project for every university student.
