I will add, though, that this plan doesn't seem to have been entirely set in stone. I think Rawle did at least consider the possibility of staying in England and becoming a lawyer there if the opportunities were better in England. The point you miss about Rawle, was that while he was away in England studying Blackstone, etc. The Rest of America was studying Vattel. Rawle MISSED that most important period when the ideas of Vattel were Dominating America.
United States Supreme Court:
UNITED STATES STEEL CORPORATION et al., Appellants, v. MULTISTATE TAX COMMISSION et al.
Argued: Oct. 11, 1977.
Decided: Feb. 21, 1978.
The international jurist most widely cited in the first 50 years after the Revolution was Emmerich de Vattel.
Rawle Missed the Vattel lessons.
“Rawle Missed the Vattel lessons.”
But what about all the newly trained lawyers from William and Mary?
“Wythe began teaching law at the College in January 1780. His students learned the nuances of the English common law, relying in significant measure on Blackstone’s Commentaries. Wythe also had his students read the work of contemporary political theorists, such as Montesquieu, and classical writers such as Horace and Virgil.”
