Read even what you don't like
Unlovable main characters can still tell important stories: When there's a compulsion to share everything that we're reading, watching, and hearing, there's also a risk that people will jump to the wrong conclusions about what others are consuming. Sometimes it's important to read books with unlovable main characters because they are essential to telling necessary stories. Kudos to the teachers who know and practice that, even in a time when it's all too easy for parents to make a fuss over imperfect books (and certain school boards to do the same with imperfect historical figures).
■ It's too much to expect that an author writing in the early 20th Century would have been adequately sensitive to the mainstream of what we consider right today. And yet, Sinclair Lewis has much to say to people living today, with books like "It Can't Happen Here" (profoundly relevant in the shadow of Donald Trump), "Babbitt" (which speaks directly to our modern crisis of meaning), and "Arrowsmith" (which addressed the wrenching ethics of epidemiology).
■ We shouldn't look past the shortcomings of the stories our forebears wrote, and we shouldn't be satisfied with any modern curriculum or syllabus that overlooks the historically under-represented stories of people who weren't white men. Yet we also shouldn't purge imperfect works and imperfect authors and imperfect protagonists. It's important to recognize at what stages we truly do stand on the shoulders of those who came before us. The society we occupy today is evolving all the time, and whether that evolution is a positive one -- marked by growth and liberality -- depends heavily upon whether we recognize society-building as a conscious choice. Uncivilized barbarians walk among us all the time: They're called children. We have to choose to teach them (and ourselves) along the way.
■ A common mistake is imagining that we are headed for some kind of perfect end times, that some kind of perfect past can be restored (as from an idealized edition of the 1950s), or that there is some kind of utopian state that can be achieved if only the right conditions are established. The fact is that society is imperfect (and permanently imperfectible) because it's made up of people, and we ourselves are imperfect. Far better to accept the inevitability of that imperfection and in the process face up to the perpetual hard work of making both people and society better than to succumb to the false notion that if we only purge hard enough, we'll make the perfect come true.
