In William Styron's memoir "Darkness Visible," he addresses the profound philosophical issue of suicide, emphasizing that it represents the ultimate question concerning the value of life. Styron argues that determining whether life is worth living is central to philosophical inquiry and reflects our deepest struggles and contemplations. This existential dilemma forces individuals to confront their own beliefs and values about existence itself.

Styron's exploration reveals the complexity and intensity of human emotions associated with despair and mental illness. The struggle with suicidal thoughts poses significant challenges, not just for individuals but also for society as a whole, as it calls into question the purpose and meaning of life. His reflection invites readers to consider the weight of such decisions and the impact of mental health on one's view of life and its worth.
