Practice the Virtue of Authenticity

Peter Boghossian says we need to practice the virtue of authenticity. To be authentic people means we should never pretend to know something we don't know. If someone asks us a question and we don't know the answer, we shouldn't pretend that we do. As an atheist like myself, we think most Christians lack this virtue, because people cannot be authentic who say they are 100% confident in their faith.
