An intellectual is a person who engages in critical thinking, research, and reflection about the nature of reality, especially the nature of society and proposed solutions for its normative problems. Coming from the world of culture, either as a creator or as a mediator, the intellectual participates in politics, either to defend a concrete proposition or to denounce an injustice, usually by either rejecting, producing or extending an ideology, and by defending a system of values.
Rudolf John Frederick Lehmann (2 June 1907 – 7 April 1987) was an English publisher, poet and man of letters. He founded the periodicals New Writing and The London Magazine, and the publishing house of John Lehmann Limited.
Samuel Johnson (18 September [O.S. 7 September] 1709 – 13 December 1784), often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The Oxford Dictionary of National Biography calls him "arguably the most distinguished man of letters in English history".
Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford, until lack of funds forced him to leave. After working as a teacher, he moved to London and began writing for The Gentleman's Magazine. Early works include Life of Mr Richard Savage, the poems London and The Vanity of Human Wishes and the play Irene. After nine years' effort, Johnson's A Dictionary of the English Language appeared in 1755, and was acclaimed as "one of the greatest single achievements of scholarship". Later work included essays, an annotated The Plays of William Shakespeare, and the apologue The History of Rasselas, Prince of Abissinia. In 1763 he befriended James Boswell, with whom he travelled to Scotland, as Johnson described in A Journey to the Western Islands of Scotland. Near the end of his life came a massive, influential Lives of the Most Eminent English Poets of the 17th and 18th centuries.
Pierre Louis Moreau de Maupertuis (/ˌmoʊpɛərˈtwiː/; French: [mopɛʁtɥi]; 1698 – 27 July 1759) was a French mathematician, philosopher and man of letters. He became the director of the Académie des Sciences and the first president of the Prussian Academy of Science, at the invitation of Frederick the Great.
Maupertuis made an expedition to Lapland to determine the shape of the Earth. He is often credited with having discovered the principle of least action – a version of which is known as Maupertuis's principle – which he expressed as an integral equation that describes the path followed by a physical system. His work in natural history is interesting in relation to modern science since he touched on aspects of heredity and the struggle for life.
