In classical understanding, education is the attempt to "lead out" from within the self a core of wisdom that has the power to resist falsehood and live in the light of truth, not by external norms but by reasoned and reflective self-determination. The inward teacher is the living core of our lives that is addressed and evoked by any education worthy of the name.
