To know his rights; to exercise with order & justice those he retains
I find this excerpt to be almost ironic. Jefferson is hoping to instill a sense of morality in the students of his university, highlighting here that they exercise their rights with 'order & justice'. The flaw I find in that is that for an individual to know his own rights, he must also respect the rights of his peers. Slavery at the time was not considered an immoral practice, though the violation of African American rights was happening right in front of everyone's eyes. I acknowledge that sometimes it is hard to remove yourself from a situation to see it from a different perspective, but Jefferson's stress on rights, duties, justice, and order should have allowed him (as well as others at the time) to see the immoralities of the slave trade.
