"The human understanding from its peculiar nature, easily supposes a greater degree of order and equality in things than it really finds. When any proposition has been laid down, the human understanding forces everything else to add fresh support and confirmation. It is the peculiar and perpetual error of the human understanding to be more moved and excited by affirmatives than negatives." (Francis Bacon, 1853, Novum Organum, in The Physical and Methaphysical Works of Lord Bacon (Book 1). London: H. G. Bohn.
