It was no doubt this second of Adam's dreams that was chiefly in Keats's mind. His way of explaining his speculations to his friend is quite unstudied and inconsecutive; he is, as he says, 'continually running away from the subject,' or shall we say letting the stream of his ideas branch out into side channels from which he finds it difficult to come back? But yet their main current and purport will be found not difficult to follow, if only the reader will bear one thing well in mind: that when Keats in this and similar passages speaks of 'Sensations' as opposed to 'Thoughts' he does not limit the word to sensations of the body, of what intensity or exquisiteness soever or howsoever instantaneously transforming themselves from sensation into emotion: what he means are intuitions of the mind and spirit as immediate as these, as thrillingly convincing and indisputable, as independent of all consecutive stages and formal processes of thinking: almost the same things, indeed, as in a later passage of the same letter he calls 'ethereal musings.' And now let the poet speak for himself:-- O! I wish I was as certain of the end of all your troubles as that of your momentary start about the authenticity of the Imagination. I am certain of nothing but of the holiness of the Heart's affections, and the truth of Imagination. What the Imagination seizes as Beauty must be Truth--whether it existed before or not,--for I have the same idea of all our passions as of Love: they are all, in their sublime, creative of essential Beauty. In a Word you may know my favourite speculation by my first Book, and the little Song I sent in my last, which is a representation from the fancy of the probable mode of operating in these Matters. The Imagination may be compared to Adam's dream, he awoke and found it truth:--I am more zealous in this affair, because I have never yet been able to perceive how anything can be known for truth by consecutive reasoning--and yet it must be. Can it be that even the greatest Philosopher ever arrived at his Goal without putting aside numerous objections? However it may be, O for a life of Sensations rather than of Thoughts! It is 'a Vision in the form of Youth,' a shadow of reality to come--and this consideration has further convinced me,--for it has come as auxiliary to another favourite speculation of mine,--that we shall enjoy ourselves hereafter by having what we called happiness on Earth repeated in a finer tone. And yet such a fate can only befall those who delight in Sensation, rather than hunger as you do after Truth. Adam's dream will do here, and seems to be a Conviction that Imagination and its empyreal reflexion, is the same as human life and its spiritual repetition. But, as I was saying, the simple imaginative Mind may have its rewards in the repetition of its own silent Working coming continually on the Spirit with a fine Suddenness. To compare great
