James Allen (28 November 1864 - 24 January 1912) was a British philosophical writer known for his inspirational books and poetry and as a pioneer of the self-help movement. His best known work, As a Man Thinketh, has been mass-produced since its publication in 1903. It has been a source of inspiration to motivational and self-help authors.
In 1903 Allen published his third and most famous book As a Man Thinketh. Loosely based on the Biblical passage of Proverbs 23:7, "As a man thinketh in his heart, so is he," the small work eventually became read around the world and brought Allen posthumous fame as one of the pioneering figures of modern inspirational thought.
Allen published his own spiritual magazine, The Light of Reason, later retitled The Epoch.
His wife continued publishing the magazine under the name The Epoch. Lily Allen summarised her husband's literary mission in the preface to one of his posthumously published manuscripts, Foundation Stones to Happiness and Success saying:
"He never wrote theories, or for the sake of writing; but he wrote when he had a message, and it became a message only when he had lived it out in his own life, and knew that it was good. Thus he wrote facts, which he had proven by practice."
