Perspective

C.S. Lewis said it is important to read old books because people during different times had different blind spots than we do.  Sure we see their foibles clearly, but so can they see ours. That's why it's also important to listen to people who are very different than us. They may have blind spots too, but theirs are not ours, otherwise we'd agree with them. Between the two of us, we'll probably have fuller vision.
