It’s the “dead” part that is the most problem. The goal is not to increase the number of voices the student hears, but to reduce them, so that only the present exists. The illusion of multiculturalism is not hard to overcome, as what they mostly mean is different foods, music, ways of dress. Fun stuff. Not too intellectually demanding. One can indeed learn something about other cultures by reading Zora Neal Hurston and Ida B Wells, and should. But they aren’t very dead, not even a hundred years, and the cultures the write about still not so very far from ours. And even they, if I can tell aright from this distance, are not read for what is different about their lives but for what the student can pretend is “just the same,” as illustrations that prejudice America now is really not that far from what they wrote about. Those two women would say otherwise, I have no doubt. They sang more than one note.
Female writers are few as one goes back in history, as are writers of color. Yet this is a feature, not a bug, as it becomes difficult to find anyone from the past who might whisper to the student that people thought otherwise than they do today. Let us talk about the prejudices they faced, children – just like today! Pay no attention to how their values and motivations were not quite the same as ours, because then we might learn something from them. We therefore have only moderns to draw from, people who drive cars, watch TV, go to restaurants, and get everything from markets. The amount of diversity is going to of necessity be quite limited.
