“Everything must be structured around the center - from the core of the being of the person and not just one aspect of him, from his heart, as the vernacular names the source of the individual - and not from his head. The excessive stretching of the consciousness of responsibility - for which the excessive expansion of the belief in reason, in the social and political effectiveness of conviction, is to blame - already has been broken asunder in the world ... For the most serious human evil is lack of moderation.”
