Meliorism
noun /ˈmiːliərɪzəm/ — The belief that the world can and will be made better through human effort.
Definition
The philosophical position that the world is neither entirely good nor irredeemably bad, but can be progressively improved through deliberate human action — a principled optimism grounded in effort rather than faith.
Beyond the definition
Meliorism is optimism with its sleeves rolled up. It doesn't deny the world's brokenness — it refuses to be paralysed by it. It is the philosophy of people who act, not because they are certain of the outcome, but because the alternative is worse.
Origin & history
From Latin melior (better) + -ism (philosophical position). Coined by George Eliot (Mary Ann Evans) in correspondence, later popularised by philosopher William James. A position between pessimism and optimism.
