Commitment needs to be credible — the test is what the committer stands to lose, and whether the risk is shared or solitary.

The signature block is a commitment device, and the signers knew it: putting their names on this paper made them traitors under British law, punishable by hanging, which is exactly why the pledge had to be mutual. "We mutually pledge to each other" turns 56 separate men into one bound party — no one can defect quietly because everyone is equally exposed. "Lives, our fortunes, and our sacred honor" escalates deliberately: body, wealth, then the thing they valued most, reputation. Skin in the game is what makes a declaration credible; anyone can publish opinions, but only people wagering everything on them get believed. The pledge is the proof that the preceding 1,300 words were meant.
