"The Antichrist" by Friedrich Wilhelm Nietzsche is a philosophical work written in 1888 and published in 1895. Nietzsche launches a fierce critique of Christianity and modern values, arguing they spring from weakness rather than strength. He attacks Christian concepts of pity, morality, and God as life-denying forces that celebrate decline over vitality. Contrasting Christianity with Buddhism and examining the origins of religious power, Nietzsche advocates for a transvaluation of values based on the will to power rather than compassion.
