Professor Bailyn is too correct the scholar ever to make the discrediting error of omission. He does write sixteen pages on the colonists' conspiratorial bent of mind. "Mind" is also the title of the poem which he includes in his Postscript. "Mind," the poem, is "Perhaps the most subtle and penetrating" commentary on the Constitution.

Mind

Mind in its purest play is like some bat
That beats about in caverns all alone,
Contriving by a kind of senseless wit
Not to conclude against a wall of stone

It has no need to falter or explore;
Darkly it knows what obstacles are there,
And so may weave and flitter, dip and soar
In perfect courses through the blackest air.

And has this simile a like perfection?
The mind is like a bat. Precisely. Save
That in the very happiest intellection
A graceful error may correct the cave.
