Thomas Carlyle (4 December 1795 – 5 February 1881) was a Scottish philosopher, satirical writer, essayist, historian and teacher.[1] Considered one of the most important social commentators of its time, he presented many lectures during his lifetime with certain acclaim in the Victorian era. One of those conferences resulted in his famous work "On Heroes, Hero-Worship, and The Heroic in History" where he explains that the key role in history lies in the actions of the "Great Man", claiming that "History is nothing but the biography of the Great Man".
He was a very respected historian and his book The French Revolution: A History remains popular nowadays and it was the inspiration for Dickens' "A Tale of Two Cities". Carlyle's "Sartor Resartus" is considered one of the finest works of the 19th century.
A great polemicist, he called economics "the dismal science",[2] wrote articles for the Edinburgh Encyclopedia[3] and his Occasional Discourse on the Negro Question remains controversial.[4] Once a Christian, he lost his faith while attending the University of Edinburgh, embracing later a form of Deism.[5] His philosophy, combined with his appreciation of the german culture, the Norse mythology and his anti-democratic views, is considered by some a prelude for fascism.
In mathematics, he is known for the Carlyle circle,[6] a method used in quadratic equations and for developing ruler-and-compass constructions of regular polygons.
