Re Gregg Lange ’70’s column, “So Little Time” (posted at PAW Online Nov. 27): Thank you for this very poignant and reassuring reminder of all that Princeton is and has been. If there’s someone who has not felt such pangs, I’m not him. Having spent a career in medicine (professionally) and the performing arts (avocationally), there are many things for which I am grateful to Princeton. However, I can easily identify the regrets as well. My greatest one is recognizing that, as a freshman, I could have taken a course with one of the greatest theologians of the mid-20th century, Reinhold Niebuhr. While I have found I can debate both his theology and his politics, missing the opportunity to encounter thinking at that level is something I have regretted for years.
