The beginner praises easily and hardly criticizes. This is because praise is more in line with his admiration of something that, if he understands it, he feels is still unattainable for him; criticism, on the other hand, requires knowledge and security that he doesn’t have. With the experienced, the opposite is true: criticism is natural, almost automatic, and praise requires the rare virtue of recognizing in the other person, despite his own knowledge, an ability that he may not have. The beginner therefore grows by being able to criticize, while the experienced does so by learning to praise: both, in short, by going against what is easiest for them.
