Nothing is arbitrary, nothing is insulated in beauty. It depends forever on the necessary and the useful. The plumage of the bird, the mimic plumage of the insect, has a reason for its rich colors in the constitution of the animal. Fitness is so inseparable an accompaniment of beauty, that it, has been taken for it.
Ralph Waldo EmersonWisdom is like electricity. There is no permanently wise man, but men capable of wisdom, who, being put into certain company, or other favorable conditions, become wise for a short time, as glasses rubbed acquire electric power for a while.
