Philip Khuri Hitti (فيليب خوري حتي in Arabic),(1886 - 1978), born in Shimlan, Ottoman Syria, now modern day Lebanon), was a scholar of Islam and introduced the field of Arab culture studies to the United States. He was of Maronite Christian religion.

Hitti was educated at an American Presbyterian mission school at Suq al-Gharb and at the American University of Beirut. After graduating in 1908 he taught at the American University of Beirut before moving to Columbia University where he taught Semitic languages and got his PhD in 1915. After World War I he returned to American University of Beirut and taught there until 1926. In February 1926 he was offered a Chair at Princeton University which he held until he retired in 1954. He was both Professor of Semitic Literature and Chairman of the Department of Oriental Languages. After formal retirement he accepted a position at Harvard. He also taught in the summer schools at the University of Utah and George Washington University in Washington, D.C. He subsequently held a research position at the University of Minnesota. Philip Hitti almost single handedly created the discipline of Arabic Studies in the United States.

Thomas Carlyle (4 December 1795 – 5 February 1881) was a Scottish satirical writer, essayist, historian and teacher during the Victorian era. He called economics "the dismal science", wrote articles for the Edinburgh Encyclopedia, and became a controversial social commentator.

Coming from a strict Calvinist family, Carlyle was expected to become a preacher by his parents, but while at the University of Edinburgh he lost his Christian faith. Calvinist values, however, remained with him throughout his life. His combination of a religious temperament with loss of faith in traditional Christianity, made Carlyle's work appealing to many Victorians who were grappling with scientific and political changes that threatened the traditional social order. He brought a trenchant style to his social and political criticism and a complex literary style to works such as The French Revolution: A History (1837). Dickens used Carlyle's work as a primary source for the events of the French Revolution in his novel A Tale of Two Cities.
