He is a skilful doctor who can give me a recipe for the cure of a bad memory. And yet we have some hints from experience on this subject. And first, _health_. It is found that we remember best when the head is clear, when we are thoroughly awake. When the body is in a quiescent state in the absence of the passions, in the moderation of food, it yields itself a willing medium to the intellect. For the true river Lethe is the body of man, with its belly and uproar of appetite and mountains of indigestion and bad humors and quality of darkness. And for this reason, and observing some mysterious continuity of mental operation during sleep or when our will is suspended, ’tis an old rule of scholars, that which Fuller records, “’Tis best knocking in the nail overnight and clinching it next morning.” Only I should give extension to this rule and say Yes, drive the nail this week and clinch it the next, and drive it this year and clinch it the next. But Fate also is an artist. We forget also according to beautiful laws. Thoreau said, “Of what significance are the things you can forget. A little thought is sexton to all the world.” We must be severe with ourselves, and what we wish to keep we must once thoroughly possess. Then the thing seen will no longer be what it was, a mere sensuous object before the eye or ear, but a reminder of its law, a possession for the intellect. Then we relieve ourselves of all task in the matter, we put the _onus_ of being remembered on the object, instead of on our will. We shall do as we do with all our studies, prize the fact or the name of the person by that predominance it takes in our mind after near acquaintance. I have several times forgotten the name of Flamsteed, never that of Newton; and can drop easily many poets out of the Elizabethan chronology, but not Shakespeare. We forget rapidly what should be forgotten. The _universal_ sense of fables and anecdotes is marked by our tendency to forget name and date and geography. “How in the right are children,” said Margaret Fuller, “to forget name and date and place.” You cannot overstate our debt to the past, but has the present no claim? This past memory is the baggage, but where is the troop? The divine gift is not the old but the new. The divine is the instant life that receives and uses, the life that can well bury the old in the omnipotency with which it makes all things new.
