 Nietzsche is arguably most famous for his criticisms of traditional European moral commitments, together with their foundations in Christianity. This critique is very wide-ranging; it aims to undermine not just religious faith or philosophical moral theory, but also many central aspects of ordinary moral consciousness, some of which are difficult to imagine doing without (e.g., altruistic concern, guilt for wrongdoing, moral responsibility, the value of compassion, the demand for equal consideration of persons, and so on).
