The soul is a monarch whose rule includes three realms. Its throne is in the present, but its scepter extends backward over yesterday and forward over to-morrow. The divinity that presides over the past is memory; to-day is ruled by reason, to-morrow is under the regency of hope. In every age memory has been an unpopular goddess. The poet Byron pictures this divinity as sitting sorrowing midst mouldering ruins and withering leaves. But the orators unveil the future as a tropic realm, magical, mysterious and surpassingly rich. The temple where hope is worshiped is always crowded; her shrines are never without gifts of flowers and sweet songs. But at length has come a day when man perceives that the vast treasure to which the present has fallen heir was bequeathed by that friend called yesterday. The soul increases in knowledge and culture, because as it passes through life's rich fields memory plucks the ripe treasure on either hand, leaving behind no golden sheaf. Philosophy, therefore, opposes that form of poetry that portrays yesterday by the falling tower, the yellow leaf, the setting sun. Memory is a gallery holding pictures of the past. Memory is a library holding wisdom for to-morrow's emergencies. Memory is a banqueting-hall on whose walls are the shields of vanquished enemies. Memory is a granary holding bread for to-morrow's hunger, seed for to-morrow's sowing. That man alone has a great to-morrow who has back of him a multitude of great yesterdays. Aristotle used memory as a measure of genius. He believed that every great man was possessed of a great memory in his own department. He was the great artist whose mind searched out and whose memory retained the beauty of each sweet child, the loveliness of each maiden and mother. He was the great scientist who remembered all the facts, forgot no exception, and grouped all under laws. The great orator was he whose memory stood ready to furnish all truths gleaned from books and conversation, from travel and experience--weapons these with which the orator faces his hearers in a noble cause, controls and conquers them.
