The work of Renoir, after that of Cézanne whose great influence had been manifested among artists, save us from whatever drying effect there is in pure abstraction. The rules that one might deduce in considering the work of these two masters appear to be more difficult to discover in the work of Renoir, who hides his efforts better. Whereas the continuous tension of the mind of Cézanne, his lack of self-confidence, prevent him from giving himself to us entirely even though he shows the evidence of his corrections, from which are easily (too easily) deduced rules that have a mathematical precision.
