“
Great virtues may draw attention from defects, they cannot sanctify them. A pebble surrounded by diamonds remains a common stone, and a diamond surrounded by pebbles is still a gem. No one should attempt to refute an argument by pronouncing the name of some man, unless he is willing to adopt all the ideas and beliefs of that man. It is better to give reasons and facts than names. An argument should not depend for its force upon the name of its author. Facts need no pedigree, logic has no heraldry, and the living should not awed by the mistakes of the dead.
