Artists are the educators of humanity. Tutors and professors instruct princes and kings, but poets (and all genuine artists are poets) educate nations. Take from Greece Homer and Phidias, and Sophocles and Scopas, and the planner of the Parthenon, and you efface Greece from history. Wanting them, she would not have been the great Greece that we know; she would not have had the vigor of sap, the nervous vitality, to have continued to live in a remote posterity, immortal in the culture, the memories, and the gratitude of men. So great, so far-stretching, so undying is the power of this exalted class of men, that it were hardly too much to say that had Homer and Phidias never lived, we should not be here today. If this be deemed extravagant, with confidence I affirm that but for the existence of the greatest artist the world has ever known,--of him who may be called the chief educator of England,--but for Shakespeare, we assuredly should not be here to-day doing the good work we are doing. There are probably some of this company who, like myself, having had the good fortune to be in London at the time of the world's fair, stood under that magnificent, transparent roof, trod that immense area whereon fifty thousand people moved at ease. It was a privilege,--the memory of which will last a life-time, to have been admitted into that gigantic temple of industry, there to behold in unimaginable profusion and variety the product of man's labor, intellect, and genius, gathered from the four corners of the earth into one vast, gorgeous pile,--a spectacle peerless from its mere material splendor, and from its moral significance absolutely sublime.
