Why is the sky blue? -A fair enough question, and one I have learned the answer to several times. Yet every time I try to explain it to someone or remember it to myself, it eludes me. Now I like to remember the question alone, as it reminds me that my mind is essentially a sieve, that I am mortal.

The part I do remember: that the blue of the sky depends on the darkness of empty space behind it. As one optics journal puts it, "The color of any planetary atmosphere viewed against the black of space and illuminated by a sunlike star will also be blue." In which case blue is something of an ecstatic accident produced by void and fire.

But what kind of love is it, really? Don’t fool yourself and call it sublimity. Admit that you have stood in front of a little pile of powdered ultramarine pigment in a glass cup at a museum and felt a stinging desire. But to do what? Liberate it? Purchase it? Ingest it? . . . You might want to reach out and disturb the pile of pigment, for example, first staining your fingers with it, then staining the world. You might want to dilute it and swim in it, you might want to rouge your nipples with it, you might want to paint a virgin’s robe with it. But still you wouldn’t be accessing the blue of it. Not exactly.
