For modern advocates of the theory, see Kant, Critique of Pure Reason, sec. 15; Religion in. d. Grenzen d. bl. Vernunft, 26, 27; Julius Müller, Doctrine of Sin, 2:357-401; Edward Beecher, Conflict of Ages. The idea of preëxistence has appeared to a notable extent in modern poetry. See Vaughan, The Retreate (1621); Wordsworth, Intimations of Immortality in Early Childhood; Tennyson, Two Voices, stanzas 105-119, and Early Sonnets, 25—“As when with downcast eyes we muse and brood, And ebb into a former life, or seem To lapse far back in some confused dream To states of mystical similitude; If one but speaks or hems or stirs his chair, Ever the wonder waxeth more and more, So that we say ‘All this hath been before, All this hath been, I know not when or where.’ So, friend, when first I looked upon your face, Our thought gave answer each to each, so true—Opposed mirrors each reflecting each—That though I knew not in what time or place, Methought that I had often met with you, And either lived in either’s heart and speech.” Robert Browning, La Saisiaz, and Christina: “Ages past the soul existed; Here an age ’tis resting merely, And hence fleets again for ages.” Rossetti, House of Life: “I have been here before, But when or how I cannot tell; I know the grass beyond the door, The sweet, keen smell, The sighing sound, the lights along the shore. You have been mine before, How long ago I may not know; But just when, at that swallow’s soar, Your neck turned so, Some veil did fall—I knew it all of yore”; quoted in Colegrove, Memory, 103-106, who holds the phenomenon due to false induction and interpretation.
