In Joseph J. Ellis's "American Sphinx: The Character of Thomas Jefferson," the author explores Thomas Jefferson's philosophy and worldview. Rather than focusing on intricate details of life and spirituality, Jefferson perceived the divine as manifested in the grandeur of the cosmos. This perspective reflects his belief in reason and natural law, which shaped his approach to governance and ethics.

Ellis highlights how Jefferson’s connection to the universe influenced his vision of democracy and individual liberty. By placing God in the expansive sky and stars, Jefferson emphasized a broader understanding of existence that transcended the minutiae of daily life, advocating for a worldview that celebrated human potential and enlightenment.
