The preservationist is not an elitist who wants to exclude others, notwithstanding popular opinion to the contrary; he is a moralist who wants to convert them. He is concerned about what other people do in the parks not because he is unaware of the diversity of taste in the society, but because he views certain kinds of activity as calculated to undermine the attitudes he believes the park can, and should, encourage.
