'Christianity Unveiled' by Nicolas-Antoine Boulanger is a thought-provoking and controversial examination of the principles and effects of Christianity. Written during the Enlightenment, Boulanger's work contributed to the changing public mindset that ultimately led to the French Revolution. He argues that Christianity is a collection of absurdities, fables, and dogmas borrowed from other ancient superstitions, and that it has been the cause of countless wars and persecutions throughout history. Despite its flaws, some argue that a religion is necessary for the ignorant masses to maintain morality. Boulanger refutes this notion, asserting that truth is always useful and that enlightened individuals are the true friends of peace.
