In "Anachronistic Arrogance" in Religion Dispatches, Peter Laarman is critical of a tendency to dismiss the positive ideas, accomplishments, or art of historical figures because their social politics are not up to our progressive standards. I think of John Fowles in The French Lieutentant's Woman, speaking to his ages' sense of superiority over the Victorians:
"So much the better for us? Perhaps. But we are not the ones who will finally judge."
Happily, Laarman explicitly addressed the thought I had while reading his article (and often have when considering this problem of "anachronistic arrogance," as Laarman puts it):
"A little generosity and humility are called for here. I predict that the rap on this generation, and on even the most progressive among us, will end up being homo sapiens “species-ism.” And how will we feel when our good works and thoughts are dismissed because we disdained the sensibilities of whales and dolphins and horses and frogs and (yes) even that little piglet who contributed to yesterday’s breakfast?"
