"In the search for truth, -- everything in nature seems to hide, -- man needs
the assistance of all his faculties. All the senses should be awake. Humor
should carry a torch, Wit should give its sudden light, Candor should hold
the scales, Reason, the final arbiter, should put his royal stamp on every
fact, and Memory, with a miser's care, should keep and guard the mental gold."
[Robert G. Ingersoll, Response to Wm. E. Gladstone on
his letter "Regarding Col. Ingersoll on Christianity;
Some Remarks on his Reply to Dr. Field", 1888]
