QUOTE : We can judge the inestimable value of concepts, and consequently of the faculty of reason, if we glance at the endless multitude and variety of things and conditions coexisting and succeeding one another, and then reflect that language and writing (the signs of concepts) are nevertheless able to afford us accurate information about everything and every relation, whenever and wherever it may have been, in that comparatively few concepts concern and represent an infinite number of things and conditions.
