Seek not proud riches, but such as thou mayest get justly, use soberly, distribute cheerfully, and leave contentedly.
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
