“The question, is it true? can be asked of anything we read. It is applicable to every kind of writing, in one or another sense of "truth" -- mathematical, scientific, philosophical, historial and poetical. No higher commendation can be given any work of the human mind than to praise it for the measure of truth it has achieved; by the same token, to criticize it adversely for its failure in this respect is to treat it with the seriousness that a serious work deserves.”
