Upon reading Walter Cunningham’s op-ed [“Winning the War with Global Warming Alarmists,” Commentary, July 9, page 19], my observation is that he comes across as a skeptic, not a realist. As a purported realist, it would be helpful to know what kind of realist: Naive? Direct? Representative? Critical? Epistemological? Objective? Hyper-transcendental? Platonic? Scientific? There are so many kinds of realists.
