The soul-making theodicy argues that God permits evil and suffering because they serve an essential purpose in human moral and spiritual development. This theodicy claims that a world containing challenges, hardships, and genuine moral choices provides the necessary conditions for developing virtues like courage, compassion, and resilience that could not exist in a paradise without suffering. The argument maintains that God's ultimate purpose is not to maximize pleasure or minimize pain, but to create beings capable of genuine moral growth and spiritual maturity through their responses to adversity.
The soul-making theodicy finds its modern articulation in John Hick's "Evil and the God of Love" (1966), drawing on earlier insights from Irenaeus of Lyon (130-202 CE) who distinguished between humans created in God's "image" versus God's "likeness." Hick developed this Irenaean tradition against the dominant Augustinian view, arguing that humans were created immature and must undergo moral development. Richard Swinburne in "The Existence of God" (1979) and "Providence and the Problem of Evil" (1998) expanded this framework, emphasizing how suffering enables moral responsibility. Marilyn McCord Adams in "Horrendous Evils and the Goodness of God" (1999) refined the approach while acknowledging its limitations regarding extreme suffering.
The strongest theistic reply to soul-making theodicy comes from those who argue it fails to justify the extent and distribution of suffering. Critics like William Rowe in "The Problem of Evil and Some Varieties of Atheism" (1979) contend that gratuitous evils exist that serve no soul-making purpose, particularly the suffering of young children and animals incapable of moral growth. D.Z. Phillips in "The Problem of Evil and the Problem of God" (2005) argues the theodicy instrumentalizes suffering unethically. Defenders respond that we cannot judge what suffering is truly gratuitous given our epistemic limitations, and that the theodicy need not justify every instance of evil but only show the logical compatibility of God and evil. They emphasize that soul-making requires genuine risks and consequences, not a controlled environment where all suffering leads directly to growth.
Soul-making theodicy differs from other formulations within the problem of evil family in its constructive approach. Unlike the logical problem of evil, which claims necessary incompatibility between God and evil, or the evidential problem of evil, which argues that evil's extent makes God's existence improbable, soul-making theodicy offers a positive account of evil's purpose. It contrasts with the free will defense by focusing on character development rather than merely the value of libertarian freedom, and unlike skeptical theism's emphasis on our cognitive limitations, it provides substantive claims about evil's role in human development.
