I think the issue of whether someone is extremely famous or not will invoke investigation of two issues. One is the issue of perspective and who makes the judgement call and the second issue is one of values and how we, as impartial observers, value different aspects of life in general. Third, and very likely the most important issue, is how society values them? Peale is currently in the Alumni section and I think it is only fair to keep it that way. It might be interesting to pose for discussion whether his contributions in the spiritual world are more important than other people's contributions in the worlds of science, politics, education and so on. This, without a doubt, will generate an unambigously political discussion and a very controversial one as well. If you are a deeply religious person, you might say that religion is very important. On the other hand, if you are a humanist, you very likely will disagree. Most people will opt for the middle ground on placing a judgement call. I think focusing on his work without redundant characterizations will reduce debate on the controversial topic of religion and its importance of life.
