Pathos

The Treaty of Paris is, in a sense, an argument about why the two nations shouldn't be at war. The intro includes this gem, imploring both sides:

[…] to forget all past misunderstandings and differences that have unhappily interrupted the good correspondence and friendship which they mutually wish to restore, and to establish such a beneficial and satisfactory intercourse, between the two countries upon the ground of reciprocal advantages and mutual convenience as may promote and secure to both perpetual peace and harmony.

That's tugging on some 18th-century heartstrings.

While reading, you get the sense that the treaty keeps trying to convince anyone reading that everything's cool now. The articles themselves, however, present solid arguments for why there was fighting to begin with—check out Article 1, which stipulates the independence of the United States—but the Treaty mentions that these issues have been solved, so it's all good.
