evidence: Thomas Jefferson was perhaps one of the most important presidents of the United States. He helped elaborate upon the most important document in US history – The Declaration of Independence – not only for the rights of the US, but for human rights in general. He was also precise when separating what he could control from what he could not, which is the key tenet of Stoicism. By doing so, he changed the course of history and the profile of an entire country. [...] In a letter titled a "Decalogue of Canons for observation in practical life", Thomas Jefferson wrote to his friend, who wished to pass Jefferson’s wisdom down to his own son so that he may become an honorable man. This letter contained a list of advice in the form of ten rules, which strongly resemble the values of Stoicism. [...] This document, among other important documents, has been an upholder of human rights and has had an enormous importance worldwide. As we can see in the latest events of violence occuring around the world, we can see that Jefferson was really ahead of his time.
