Constitutions built upon a separation of powers were not made to last. The conceit that executive and legislative branches of government might be set in equipoise, and balance each other off over the decades, was amusingly mocked by Oliver Wendell Holmes, Sr. in The Deacon’s Masterpiece (1858):
Have you heard of the wonderful one-hoss shay,
That was built in such a logical way
It ran a hundred years to a day…?
The secret to building a carriage, the Deacon thought, was to make each piece as strong as the rest, so that no one part wears out first. And as there’d never be a weakest spot, the shay would go on forever, just like the imagined Madisonian Constitution. Well, it lasted and lasted, the talk of the town, until 100 years to the day it all collapsed at once and the new owner found himself sitting on a pile of ashes. No part wore out first. Everything went simultaneously. “End of the wonderful one-hoss shay. Logic is logic. That’s all I say.”
