At Harvard University, more than 40 chaplains attend to the spiritual well-being of the university's students, faculty and staff. They have elected a new president. He is Greg Epstein, the humanist chaplain at Harvard. In other words, he serves the humanist, atheist, agnostic and non-religious at the university and larger community. He also represents the fast-growing number of Americans who do not associate themselves with a religious group, sometimes referred to as nones, as in no affiliation, a group that now rivals white evangelicals and Catholics in size.
