    ' Homo nature minister et interpres, tantum facit et intelligit, quantum de naturae online, re vel mente obser- vaverit; nec amplius seit, aut potest.' Bacon's Novum Organum. ' There is no well-attested case on record of any theory having. been abandoned because it produced dangerous results. As long as a theory is believed, men will ascribe its evil consequences to any cause except the right one. And a theory which is once established will always be believed until there is some change in knowledge which shakes its foundation. Every practical change may, by careful analysis, be shown to depend, in the first instance, on some change of speculative opinions.' Buckle's History of Civilization in England, vol. ii. p. 545, note.
