Today is Sunday, but of course it's not really Sunday except by social convention. Social convention weaves us together, so convention has some peaceful purposes. But still, you might think we could keep things honest, with or without social convention. Let us bond and cling and hug, perhaps, but "Sunday" is not actually Sunday, right?
And by extension, I am the amalgamation of my conventions -- conventions that make me socially acceptable, perhaps, but not assuring any sort of actual-factual truth. In a conventional sense, I am Sunday -- I am I -- but must this recognition eradicate or dispose of the facts? I don't think so. A pulsing and insistent convention is just that. But the fact that it is "just that" needn't necessarily turn its nose up to the fact that Sunday is not precisely Sunday any more than I am actually I.
Increasingly, these days, I have to check in with someone or some computer thing to recall my social convention. It's Sunday, I am informed. OK, no need to worry. I am on terra firma ... except that the terra firma, while being terra, is much less than firma.
I guess all of this jibber-jabber takes root in the fact that daylight saving time is about to reverse course in the wee hours of tomorrow morning: Clocks will be set back an hour to accommodate the farmers of yore.
"Tomorrow" -- another social convention that's hard to break away from however intellectually obvious it may be. I am the sum of my conventions and my conventions need readjusting.
