All our petty tribalisms section us off from the political community. Each tribe is relegated to its own division but must force conformity there just to maintain the whisper of solidarity forestalling further breakdown into smaller and smaller sub-tribes. This is all because we do not know how to act in the public sphere, for which reason too we do not know to belong to a political community. And why do we not know how to act in the public sphere? Because we don't know why! And what is that why? Because we are human! What does that mean? Now we are entering the realm of metaphysics and should begin a discussion.
