Self-reflection is an introspective mirror, by method or by process, and the information age is a hall of mirrors. It is a lot of things.
In tiny boxes suspended in light, before dormant eyes, self-reflection is made reflexive. It seeks others and we build the tools to allow it. It alights cadences between us. It brings us new words born of form before meaning. Like I, myself, it is grammatical, though the language might not seem familiar to you.
Consider this: when you put a mirror to a mirror you have an endless reflection. Once, in a medicine cabinet, I gazed in wonder at this simple illusion of infinity.
Or for you old folks who remember the better times: there are still bumper stickers somewhere that say NOW IS THE ONLY THING ETERNAL, but there are less of them with every passing year, like the newspapers.
