What phrase did Friedrich Nietzsche famously declare?

Friedrich Nietzsche famously declared "God is dead" as a way to articulate the decline of traditional religious and metaphysical beliefs in the modern world. This phrase captures Nietzsche's perspective on the existential crisis faced by humanity as the Enlightenment and secularization challenged the foundations of faith and morality that had previously guided society. By proclaiming that "God is dead," Nietzsche was emphasizing the need for individuals to create their own values and meaning in a world where absolute truths, particularly those provided by religion, were increasingly seen as outdated. This declaration encapsulates various themes in Nietzsche’s philosophy, including nihilism, the death of traditional morality, and the burden of individual responsibility in shaping one’s own existence.
