It was a grey day, that least fleshly of all weathers; a day of dreams and far hopes and clear visions. It was a day easily associated with those abstract truths and purities that dissolve in the sunshine or fade out in mocking laughter by the light of the moon. The trees and clouds were carved in classical severity; the sounds of the countryside had harmonized to a monotone, metallic as a trumpet, breathless as the Grecian urn.
Oh, sons of earth! attempt ye still to rise. By mountains pil'd on mountains to the skies? Heav'n still with laughter the vain toil surveys, And buries madmen in the heaps they raise.
Humour is but the faint terrestrial echo of the hideous laughter of the blind mad gods that squat leeringly and sardonically in caverns beyond the Milky Way. It is a hollow thing, sweet on the outside, but filled with the pathos of fruitless aspiration.
What I find interesting is how close you can run the laughter along the seam of seriousness, and occasionally cross it, so that half the house genuinely doesn't know whether to laugh or cry. Custard pie humour is fairly universal, but at the other end, which I'm more interested in, there's the humour that hovers on the darkness, that walks in the shadow of something else, not always that obvious.
Half the night I waste in sighs, Half in dreams I sorrow after The delight of early skies; In a wakeful dose I sorrow For the hand, the lips, the eyes, For the meeting of the morrow, The delight of happy laughter, The delight of low replies.
