In the artist Redon's own engaging words:
"One who teaches, after all, wishes nothing better than to continue the work of the masters, but alas, even only to transmit it, he does not quite have their permission. Indeed he indulges in them as he is able, as best he can, as does the grammarian by analysis of the beautiful works of the past which time has consecrated, but there he acquires only abstract experience, all in formulas, where the engaging authority of love is missing. One must love in order to believe, one must believe in order to act: the best teaching, then, will be received from one who already has touched the apprentice through a sort of creative revelation that issues from the beauty of his own works."
