EVEN THE SHADOWS ARE NECESSARY TO THE PERFECTION OF A PICTURE.
11. Is it true that all things are produced by necessity, and by the natural concatenation of causes and effects, and that, thus, they are as good as possible? No! It is the Reason which, governing the world, produces all things (in this sense that it contains all the "seminal reasons"), and which decrees that they shall be what they are. It is Reason that, in conformity with its rational nature, produces what are called evils, because it does not wish everything to be equally good. An artist would not cover the body of a pictured animal with eyes.[57] Likewise, Reason did not limit itself to the creation of divinities; it produced beneath them guardians, then men, then animals, not by envy (as Plato remarks[58]); but because its rational essence contains an intellectual variety (that is, contains the "seminal reasons" of all different beings). We resemble such men as know little of painting, and who would blame an artist for having put shadows in his picture; nevertheless, he has only properly disposed the contrasts of light. Likewise, well-regulated states are not composed of equal orders. Further, one would not condemn a tragedy, because it presents personages other than heroes, such as slaves or peasants who speak incorrectly.[78] To cut out these inferior personages, and all the parts in which they appear, would be to injure the beauty of the composition.[59]
