What Is Man? And Other Irreverent Essays (ed., Mark Twain)

This volume collects Mark Twain's most penetrating philosophical essays examining religious belief, human nature, and the concept of God, showcasing his evolution from cultural satirist to serious philosophical critic of theism. Under S. T. Joshi's editorial guidance, the collection presents Twain's systematic dismantling of Christian theology and his broader critique of religious thinking as fundamentally incompatible with reason and human progress.

The titular essay "What Is Man?" employs a Socratic dialogue format to advance Twain's deterministic philosophy, arguing that humans are merely machines programmed by heredity and environment, lacking free will or genuine moral agency. This mechanistic view directly challenges Christian notions of sin, redemption, and divine judgment. Twain contends that belief in personal responsibility and divine oversight represents a dangerous delusion that prevents humans from understanding their true nature and improving their condition through rational means.

Other essays in the collection extend this critique. "Letters from the Earth" presents Satan's sardonic reports to heaven about humanity's absurd religious beliefs, exposing what Twain sees as the logical contradictions and moral failures of Christian theology. His analysis particularly targets the concept of a benevolent God who permits suffering, creates hell, and demands worship while displaying petty human emotions like jealousy and anger. "The Damned Human Race" argues that humans, far from being God's special creation, are morally inferior to animals precisely because of their capacity for cruelty justified by religious ideology.

Joshi's editorial framework situates these works within both Twain's personal journey from Presbyterian upbringing to philosophical skepticism and the broader context of late nineteenth-century American freethought. The collection demonstrates how Twain's critique moved beyond mere anticlericalism to challenge the philosophical foundations of theism itself. His arguments anticipate twentieth-century discussions about the problem of evil, religious epistemology, and the psychological origins of belief.

The volume's significance lies in presenting Twain not merely as a humorist but as a serious participant in philosophical debates about God's existence and nature. His accessible yet sophisticated arguments bridge popular and academic discourse, demonstrating how literary forms can effectively convey philosophical criticism. For scholars of American religious thought, the collection provides essential evidence of indigenous skeptical traditions that challenged the period's dominant Protestant culture through rational argument rather than mere ridicule.
