May the love for my art actuate me at all times; may neither avarice, nor miserliness, nor the thirst for glory or a great reputation engage my mind; for the enemies of Truth could easily deceive me and make me forgetful of my lofty aim in doing good ... When wiser people teach me, let me be humble to learn; for the mind of man is limited, while the practice of the art ... is vast. May I have the strength, time, and opportunity always to verify and correct what I have learned and to increase my understanding. May I always be able to discover today the errors of yesterday, and to obtain a new light tomorrow on what I think I am sure of today.
