This paper provides a logical defence of Oseni Taiwo Afisi’s alternative approach to social change, which he terms “many-pieces-at-once social engineering”. Building on Karl Popper’s distinction between utopian social engineering and piecemeal social engineering, Afisi argues that while Popper’s caution against holistic societal reconstruction remains valid, the complexity and magnitude of social problems, especially in developing societies, demand more than a one-piece-at-a-time reform strategy. His approach expands the notion of piecemeal reform to include simultaneous interventions across multiple sectors such as education, healthcare, infrastructure, governance, and security, thereby avoiding the rigidity of binary logic, limiting reform to small adjustments or total revolution. The paper examines the logical underpinning of Afisi’s approach to social change through critical and conceptual analysis methods. While using ezumezu logic as a theoretical framework, the paper argues that the logical foundation of Afisi’s argument rests on complementarity rather than binary opposition; piecemeal and many-pieces-at-once reforms are not mutually exclusive, but context-dependent and interdependent strategies justified by Popper’s rationality principle. This paper defends Afisi’s approach as both consistent with Popper’s fallibilist orientation and responsive to the urgent developmental needs of non-Western societies, where incrementalism may prove too slow. Basically, his approach offers a pragmatic and critical pathway for achieving social transformation that is rational, tentative, and democratic, while at the same time sufficiently radical to address the scale of twenty-first-century social challenges.
