What must a painter have ?

  "1. Every artist, as creator, must learn to express what is personally characteristic. (The element of personality.)

"2. Every artist, as a child of his era, must express what is characteristic of this age. (The element of style in its interior value, consisting of the language of the times and the language of the people.)

"3. Every artist, as servant of the art, must express that which is characteristic of art generally. (The element of pure and eternal art, found among all human beings, among all peoples and at all times, and which appears in the work of all artists of all nations and in all ages and which does not obey, as essential element of art, any law of space or time.)"
