Philosophical pessimism is a philosophical tradition which argues that life is not worth living and that non-existence is preferable to existence. Thinkers in this tradition emphasize that suffering outweighs pleasure, happiness is fleeting or unattainable, and existence itself does not hold inherent value or an intrinsic purpose. Philosophers such as Arthur Schopenhauer suggest responses to life's suffering, ranging from artistic contemplation and ascetic withdrawal, while Buddhism advocates for spiritual practices. Pessimism often addresses the ethics of both creating and continuing life. Antinatalists assert that bringing new life into a world of suffering is morally wrong, and some pessimists view suicide as a rational response in extreme circumstances; though Schopenhauer personally believed it failed to address the deeper causes of one's suffering.
The roots of pessimism trace back to ancient philosophies and religions. Buddhism in Ancient India identifies life as fundamentally marked by suffering (duḥkha), while thinkers like Hegesias of Cyrene in ancient Greece argued that happiness is unattainable due to constant bodily ills and unfulfilled desires. In the beginning of the Common Era, Gnostic Christianity viewed the material world as inherently flawed or evil. Moving into the 19th century, Schopenhauer introduced a systematic philosophy with pessimistic aspects at its core by conceiving of reality as being fundamentally constituted by the "Will" — a ceaseless metaphysical striving that can never be satisfied. Later thinkers, including Julio Cabrera and David Benatar, have expanded on pessimism with contemporary analyses focusing on the empirical life experiences of living beings rather than on metaphysical principles.
Critics of pessimism, such as Friedrich Nietzsche, reject its conclusions, instead celebrating struggle and suffering as opportunities for growth and self-transcendence. Pessimism’s influence extends to literature and popular culture. The character of Rust Cohle in the first season of the TV series True Detective embodies a pessimistic worldview, drawing on the works of authors such as Thomas Ligotti, Emil Cioran, and David Benatar.
