Heretics · 1905-01-01 · Essay

Author:
G. K. Chesterton

G. K. Chesterton’s 1905 collection of essays examines the ideas of prominent contemporary thinkers, such as George Bernard Shaw and H. G. Wells. The author uses the term to describe intellectuals whose modern philosophies deviate from traditional Christian orthodoxy. By challenging these popular secular views, Chesterton frames his subjects as modern-day dissenters against established moral truths.
