His reply in his own defence is long and much of it beautiful: but we follow the chain of thought and argument with difficulty, so hidden is it in flowers of poetry and so little are its vital links made obvious. A letter of Keats, containing one of his very few explanatory comments on work of his own, shows that he attached great importance to the passage and felt that its sequence and significance might easily be missed. Sending a correction of the proof to Mr Taylor, the publisher, he says--'The whole thing must, I think, have appeared to you, who are a consecutive man, as a thing almost of mere words, but I assure you that when I wrote it, it was a regular stepping of the Imagination towards a truth. My having written that argument will perhaps be of the greatest service to me of anything I ever did. It set before me the gradations of happiness, even like a kind of pleasure thermometer, and is my first step towards the chief attempt in the drama.' The first ten lines offer little difficulty:-- Peona! ever have I long'd to slake My thirst for the world's praises: nothing base, No merely slumberous phantasm, could unlace The stubborn canvas for my voyage prepar'd-- Though now 'tis tatter'd; leaving my bark bar'd And sullenly drifting: yet my higher hope Is of too wide, too rainbow-large a scope, To fret at myriads of earthly wrecks. Wherein lies happiness? In that which becks Our ready minds to fellowship divine, A fellowship with essence; till we shine, Full alchemiz'd, and free of space. Behold The clear religion of heaven! It seems clear that we have here shadowed forth the highest hope and craving of the poetic soul, the hope to be wedded in full communion or 'fellowship divine'--or shall we say with Wordsworth in love and holy passion?--with the spirit of essential Beauty in the world. In the next lines we shall find, if we read them carefully enough, that Keats, having thus defined his ultimate hope, breaks off and sets out again from the foot of a new ascending scale of poetical pleasure and endeavour which he asks us to consider. It differs from the ascending scale of the earlier poems inasmuch as it begins, not with the toying of nymphs in shady places and the like, but with thoughts of olden minstrelsy and romantic tales and prophecies. The verse here is of Keats's finest:-- --hist, when the airy stress Of music's kiss impregnates the free winds, And with a sympathetic touch unbinds AEolian magic from their lucid wombs: Then old songs waken from enclouded tombs; Old ditties sigh above their father's grave; Ghosts of melodious prophecyings rave Round every spot where trod Apollo's foot; Bronze clarions awake, and faintly bruit, Where long ago a giant battle was; And, from the turf, a lullaby doth pass In every place where infant Orpheus slept.
