The human understanding, from its peculiar nature, easily supposes a greater degree of order and equality in things than it really finds.
Francis BaconIf a man's wit be not apt to distinguish or find differences, let him study the schoolmen; for they are cymini sectores, splitters of hairs.
Francis BaconBut by far the greatest hindrance and aberration of the human understanding proceeds from the dullness, incompetency, and deceptions of the senses; in that things which strike the sense outweigh things which do not immediately strike it, though they be more important. Hence it is that speculation commonly ceases where sight ceases; insomuch that of things invisible there is little or no observation.
Francis Bacon
