Edeh claims in his Towards an Igbo Metaphysics, that the human being, is a necessary emanation from God (good in se), and so, shares in God’s goodness and perfection; hence the human being is mma-di or the ‘good that is’. The concept of mma-di raises some critical, logical and ontological issues around the nature and origin of evil in the world. This work, through qualitative textual analysis, claims that Edeh’s conception of the human being as ‘good that is’ has far reaching implications: in the first place, there is an implication of a dual ontology of good and evil. Secondly, the conception of the human being as mma-di harbours the logico-existential reality of evil as a necessary outcome of the creation of ‘good that is’. This is validated by the assumption that any conceptual existence of a good, should of necessity imply its binary opposite, that is, evil. This work asserts that implicit in Edeh’s thought is the idea that God is the creator or originator of evil, otherwise, whence comes evil since every evidence points to its existence? Here, declaring evil as “a privation” does not make any sense given the reality of evil in our actual world.
