Sec. 2. But there is no need to rest my defence on this narrow English ground. The fact is, that though the climates of the South and East may be _comparatively_ clear, they are no more absolutely clear than our own northern air; and that wherever a landscape-painter is placed, if he paints faithfully, he will have continually to paint effects of mist. Intense clearness, whether in the North after or before rain, or in some moments of twilight in the South, is always, as far as I am acquainted with natural phenomena, a _notable_ thing. Mist of some sort, or mirage, or confusion of light, or of cloud, are the general facts; the distance may vary in different climates at which the effects of mist begin, but they are always present; and therefore, in all probability it is meant that we should enjoy them. Sec. 3. Nor does it seem to me in any wise difficult to understand why they should be thus appointed for enjoyment. In former parts of this work we were able to trace a certain delightfulness in every visible feature of natural things which was typical of any great spiritual truth; surely, therefore, we need not wonder now, that mist and all its phenomena have been made delightful to us, since our happiness as thinking beings must depend on our being content to accept only partial knowledge, even in those matters which chiefly concern us. If we insist upon perfect intelligibility and complete declaration in every moral subject, we shall instantly fall into misery of unbelief. Our whole happiness and power of energetic action depend upon our being able to breathe and live in the cloud; content to see it opening here and closing there; rejoicing to catch, through the thinnest films of it, glimpses of stable and substantial things; but yet perceiving a nobleness even in the concealment, and rejoicing that the kindly veil is spread where the untempered light might have scorched us, or the infinite clearness wearied.
