Lincoln's Best Sort of Principle
Lincoln's "best sort of principle" seems worth remembering, even if it's insufficient on its own.
We see it, and to us it appears like principle, and the best sort of principle at that - the principle of allowing the people to do as they please with their own business.
This principle can be exploited and distorted so that some people get cut out and oppressed. So we can't leave it at that - it is not the only principle a decent society must have.
But it does seem a rather good principle not to forget.
