You can see Jefferson’s regular topics and conceits clearly here. A chapter on religion is mainly about the religious freedom he so assiduously (and successfully; he wrote the statute) championed in Virginia. On education, it reflect the inadequacy of both the physical and curricular structure of William & Mary, then the state’s only college; arguments no doubt in support of his quest to establish the University of Virginia at the base of his mountain. You see Jefferson the amateur scientist (and a fascinating digression into some amateur archaeology that he undertook on a Native American burial mound.
On manufacturing, his disdain for large scale production is clear (despite the fact that very nearly his only profitable venture was a nail factory he built on his lands). It feels a little naive, to disdain creating finished goods here, beyond basic items, but it fits with his pastoral/agricultural republicanism. Like Socrates, he seems to think smaller polities are better.
On race… the less said the better. He was at a point where his views were evolving and not for the better. He is open to the idea that the native peoples could achieve a cultural status close to whites, but that “generosity” only reminds the modern reader of the anti-black racism running through his brain.
Takeaway quote (from the religion section):
It is error alone which needs the support of government. Truth can stand by itself.
And you know what? In this day, his vigorous, anthropological critique of religious oppression may seem commonsensical today, in the eighteenth century it was far more daring and outre.
Doesn’t make up for the racism, though.
