Edmund S. Morgan's history of the early American republic is different from other histories I have read of the period in that it goes into many of the specific arguments each side—British and colonial—were making. Throughout the 1760s, for instance, British officials made claims that the colonists were "virtually represented," the same as non-landholding Englishmen who also couldn't vote for members of the House of Commons. In response, leading colonists developed the argument that Parliament "could legislate, but it could not tax," seeing as how the House of Commons was the only legislative body that could mandate taxes from its constituents, which the colonists were not.
The book also excels in showing how easily communication between country and colonies got confused. Instead of reinforcing the distinction between legislation and taxation when visiting England, Benjamin Franklin softened the colonists' main objection to Parliament, claiming that taxes on individuals were the real problem. So the Townshend Acts, which came next, applied import duties instead, and only further stoked the flames of hostility in their ignorant repetition of British authority.
Morgan can be quite reasonable in many cases when explaining the seemingly conflicted motivations of the colonists. He makes it clear that for as bold and courageous as they may have been, they were not saints. But, as he says, this is no reason to dismiss them as wallowing purely in self-promotion: "We will see no incongruity in their coupling of principle and self-interest if we will remember that constitutional principles have been created and continue to exist for the protection of the people who live under them. They are seldom referred to unless people fear or feel harm from their violation, and then the greater the harm the greater the clamor."
His arguments are weaker when they attempt to portray slaveholders in a more sympathetic light. Even if they harbored some inhibitions about the evil institution, or allowed manumission, or brought an end to the slave trade, this was not enough. By allowing their economic concerns to win out over humanity, they still fall squarely on the wrong side of history.
