Nihilism is a philosophical belief that life lacks inherent meaning, purpose, or value. It suggests that traditional beliefs, morals, and truths are unfounded, leading to a sense of emptiness or despair. This perspective can be unsettling, as it challenges the foundations of how people understand their existence and the world around them. Despite its bleak outlook, nihilism can also encourage individuals to create their own meaning and values. By rejecting imposed beliefs, one can explore personal freedom and authenticity. Thinkers like Friedrich Nietzsche have engaged with nihilism, arguing that it can lead to a reevaluation of life and inspire new ways of thinking.
