In The Law of the Unforeseen, the law Harkness speaks of requires us to know now and then. We walk under "the trees of unremembrance," so that we may know who we are, how we got here, and who we came from. And we arrive in this lovely and threatened paradise called Earth, right now. The "endless replication of clam shells, ants, / hyacinths in spring"?—it's true, we will lose those things, individually, but these poems savor such stuff, and in that savoring they give us hope for the future.
