Final answer:
Thomas Jefferson is recognized for using his intellect to articulate core American values and sharing them with the populace, which is true. His leadership was characterized by endorsing Enlightenment ideas, promoting an agrarian society, and valuing land ownership. However, his approaches to international diplomacy were not entirely successful.
Step-by-step explanation:
The statement that one of the many great leadership qualities of Thomas Jefferson was his ability to use his intellect to develop core American values and share them with common people is true. Jefferson was instrumental in shaping such values, as evidenced by the Declaration of Independence, which drew heavily from the theories of Enlightenment philosopher John Locke.
Jefferson's values include a firm belief in small government, an agrarian society, and land ownership as a foundation for good citizenship. His presidency also reflected these values in various ways, such as valuing diplomacy over military conflict, promoting territorial expansion, and believing in the peaceful assimilation of Native Americans into American society. However, his efforts to use economic pressure to address international conflicts, particularly with Britain and France, were not as successful as he had hoped.
