Thomas Carlyle (4 December 1795 – 5 February 1881) was a Scottish philosopher, satirical writer, essayist, translator, historian, mathematician, and teacher. Considered one of the most important social commentators of his 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 "the history of the world is but the biography of great men".Read about Thomas Carlyle in Wikipedia
Cherish what is dearest while you have it near you, and wait not till it is far away. Blind and deaf that we are; oh, think, if thou yet love anybody living, wait not till death sweep down the paltry little dust clouds and dissonances of the moment, and all be made at last so mournfully clear and beautiful, when it is too late.
