M. Scott Peck quote
there are, then, two ways to confront or criticize another human being: with instinctive and spontaneous certainty that one is right, or with a belief that one is probably right arrived at through scrupulous self-doubting and self-examination. the first is the way of arrogance; it is the most common way of parents, spouses, teachers, and people generally in their day-to-day affairs; it is usually unsuccessful, producing more resentment than growth and other effects that were not intended. the second is the way of humility; it is not common, requiring as it does a genuine extension of oneself; it is more likely to be successful, and it is never, in my experience, destructive.
