The genius of the heart, as that great anchorite possesses it, the divine tempter and born Pied Piper of consciences, whose voice knows how to sink into the inmost depths of every soul, who neither utters a word nor casts a glance, in which some seductive motive or trick does not lie: a part of whose masterliness is that he understands the art of seeming not what he is, but that which will place a fresh constraint upon his followers to press ever more closely upon him, to follow him ever more enthusiastically and whole heartedly.
