The aspects of society that humanism most exalts are justice and continuity. That is why humanism is always being presented with a contradiction. For when it speaks of justice it holds that the human condition is absolute; yet when it speaks of continuity it implies that society is not absolute but pragmatic and even anomalous. Its intelligence dictates the removal of all that is anomalous; yet its ideal of social continuity is validated by by its perception that the effort to destroy anomaly out of hand will probably bring new and even worse anomalies, the nature of man being what it is. "Let justice be done though the heavens fall" is balanced by awareness that after the heavens fall justice will not ever be done again.
