All too often, we say what we hear others say. We see what we are permitted to see. Much worse, we see what we're told that we see. Repetition and pride are the keys to this. To hear or to see even an obvious lie again and again and again, is to say it, almost by reflex, and then to defend it because we have said it, and to embrace what we've defended. Thus without thought or intent, we make mere echoes of ourselves and we say what we hear others say.
