Excerpts from Books and Wikipedia
"If Kant (1724–1804) found Christianity inadequate, he did not attack it but rather subsumed it in a more elevated moral scheme. When he defined enlightenment as using one’s ‘own understanding in religious matters, without outside guidance’, leading to ‘emergence from self-incurred immaturity’, he was not looking forward to a world without God. Those words come from his essay ‘What is Enlightenment?’, published in the Berlin Journal for Enlightenment in 1784." [Blanning: Pursuit of Glory, p. 500]
