Ludwig Feuerbach was a 19th century German philosopher known for his book The Essence of Christianity. He received his education at the universities of Heidelberg and Erlangen, where he studied theology but became associated with the Young Hegelians. His most influential work was The Essence of Christianity, in which he argued that God is a human projection of our own nature, and that religion will be superseded as humanity progresses. Feuerbach advocated for atheism, materialism, and liberalism and believed religion poisoned the sense of truth.
