We can convey an experience by a mere expression. This is data compression of impressive proportions. How much information is wrapped up in an experience, say, of love? It’s hard to say. Our species has explored love through countless songs and poems and, apparently, failed to fathom its depths: each new generation feels compelled to explore further, to forge ahead with new lyrics and tunes. And yet, despite its unplumbed complexity, love is conveyed with a glance. This economy of expression is possible because my universe of experience, and my perceptual interface, overlaps yours.
