Passage: Jefferson, while primarily a planter, lawyer and politician, mastered many disciplines, which ranged from surveying and mathematics to horticulture and mechanics. He was an architect in the classical tradition. Jefferson's keen interest in religion and philosophy led to his presidency of the American Philosophical Society; he shunned organized religion but was influenced by both Christianity and deism. A philologist, Jefferson knew several languages. He was a prolific letter writer and corresponded with many prominent people. His only full-length book is Notes on the State of Virginia (1785), considered perhaps the most important American book published before 1800.Although regarded as a leading spokesman for democracy and republicanism in the era of the Enlightenment, Jefferson's historical legacy is mixed. Some modern scholarship has been critical of Jefferson's private life, pointing out the contradiction between his ownership of the large numbers of slaves that worked his plantations and his famous declaration that "all men are created equal". Another point of controversy stems from the evidence that after his wife Martha died in 1782, Jefferson fathered children with Martha's half-sister, Sally Hemings, who was his slave. Despite this, presidential scholars and historians generally praise his public achievements, including his advocacy of religious freedom and tolerance in Virginia. Jefferson continues to rank highly among U.S. presidents.
