The standard options in religious philosophy are optimism (all is well, evil is illusory or ultimately good) and pessimism (all is fundamentally ill, salvation is impossible). James rejects both as dogmatic — both impose a verdict on a universe that is still, in his view, unfinished. What he calls meliorism is the third way: the world can be made better, and whether it is depends in part on us.
Meliorism follows from James's pluralism: if the universe is genuinely multiple and unfinished rather than a fixed whole determined by an absolute first principle, then what we do actually matters. Our choices add or subtract from the balance of good and evil. The moral and religious life is not theater performed before an omniscient audience that already knows the outcome — it is genuine creation, with genuinely uncertain results.
The pragmatist approach to religion does not require certainty or metaphysical proof. It asks: does living as though the religious hypothesis were true yield the kind of experience that vindicates belief? Does it make us more active, more morally serious, more capable of solidarity and effort? If so, it has earned its place in our intellectual economy, not as a proven fact but as a working hypothesis — and for James, that is enough.
Meliorism is developed in Lecture VIII of Pragmatism (1907). James returns to the theme in A Pluralistic Universe (1909) and in the closing lectures of The Varieties of Religious Experience (1902).
