Any man more right than his neighbors constitutes a majority of one. — Henry David Thoreau
A more accurate but less feelgood version of the original quote:
Any man who is actually right when his neighbors is wrong constitutes a majority of one.
And the corollary:
Any man who isn’t actually right but insists that he is a majority of one is just an asshole.
The world seems to have a plethora of people in the first and third categories. It’s unfortunate that we have so few in the second category.
