— Bernard of Clairvaux French abbot, theologian 1090 - 1153
Epistola CVI, sect. 2; translation from Edward Churton The Early English Church ( 1841) p. 324
Original: (la) Experto crede: aliquid amplius invenies in silvis, quam in libris. Ligna et lapides docebunt te, quod a magistris audire non possis.
