I have learned in my moderate time on earth that a lot of things “everybody knows” is wrong. Fact are ephemeral things, absolutes ever waiting for the court of science and society to overturn them. Enough of them are overturned, leaving shadows of their former selves as lingering mythologies – seeds of truth that once were, perhaps with a much diluted truth still remaining.
It’s a hard thing, this shifting of reality. The discovery that in fact your degreed education in no way signifies completion.
Know as you read this: something you know, believe, are sure of is about to be proven false. It could be minor – maybe bears don’t shit in the woods – or it might rock your world. Thus is the nature of change, and the price of passage when shuttling from birth to death.
