True facts. It's difficult to exercise discretion; the right tool for the job. No one knows everything about everything and while the influence words exert on our minds in a social context is potent, knowing, hearing or reading words does not guarantee understanding.
I feel a sense of brotherhood and deep humility with those first human beings who had no words, only each other and the immediate need to survive... I'd wager they understood each other better than most people alive today. Still, our ancestors made it through the last ice age with nothing but sticks and rocks so we've got this shit.
