Benjamin Kidd (9 September 1858–2 October 1916) was a British sociologist whose first job was a civil service clerk, but by persistent self-education, he became internationally famous by the publication of his book Social Evolution in 1894. Kidd argued that the "evolution of society and of modern civilization" is caused not by reason or science, but by the force of "religious beliefs." The book had worldwide circulation and impacted the Social Gospel movement.
