One of the best things about reading books? You get to see the world from other perspectives. New eyes. New brains. Other times. So happy to have recently "discovered" the philosopher Michel de Montaigne (1533 - 1592). He is the master of reminding us that we don't really know what we know, and we don't really know what we don't know.
"To learn that we have said or done a stupid thing is nothing, we must learn a more ample and important lesson: that we are but blockheads!"
AND...
"Our life consists partly in madness, partly in wisdom: whoever writes about it merely respectfully and by rule, leaves more than half of it behind."
