The great principle of the Zoroastrian philosophy seems to be that the thorn is essential to the rose. Or, to put it more correctly, that the life of man is a chessboard, because chess is a royal game — the great game for the human intellect. And in chess it is necessary, not only that there should be black and white, but that black and white should be equal. There must be a pattern of black and white, and the pattern must be exact.
To all this view of life I should only answer that the chessboard is only a pattern, and therefore cannot be a picture. A black-and-white artist always treats one or other colour as the background. The artist may be scrawling black on white, when he is illustrator in pen-and-ink. He may be scrawling white on black, when he is a schoolboy chalking the schoolmaster’s nose on the blackboard. But the pen-and-ink artist knows that the page is white previous to the arrival of the pen and ink. The wicked schoolboy knows that the blackboard is black. So we, as Christians, should always believe that this is a white world with black spots, not a black world with white spots. I should always believe the good in it was its primary plan. Also, I should always remember that chess came from Persia.
