The Spirit of the Age (full title The Spirit of the Age: Or, Contemporary Portraits) is a collection of character sketches by the early 19th century English essayist, literary critic, and social commentator William Hazlitt, portraying 25 men, mostly British, whom he believed to represent significant trends in the thought, literature, and politics of his time. The subjects include thinkers, social reformers, politicians, poets, essayists, and novelists, many of whom Hazlitt was personally acquainted with or had encountered. Originally appearing in English periodicals, mostly The New Monthly Magazine in 1824, the essays were collected with several others written for the purpose and published in book form in 1825.
