Man is an idolater or symbol-worshipper by nature, which, of course, is no fault of his

Context

“Channing's famous Baltimore discourse and remember the shrieks of blasphemy with which it was greeted, to satisfy yourself on this point. Time, time only, can gradually wean us from our Epeolatry, or word-worship, by spiritualizing our ideas of the thing signified. Man is an idolater or symbol-worshipper by nature, which, of course, is no fault of his; but sooner or later all his local and temporary symbols must be ground to powder, like the golden calf,—word-images as well as metal and wooden ones. Rough work, iconoclasm,—but the only way to get at truth.” source
