Welfarism and Utilitarianism: What Is the Difference?
Welfarism and utilitarianism are closely related, but they are not identical.
The basic distinction
Welfarism concerns the role welfare plays in evaluation. Utilitarianism is a family of moral theories that typically combines a welfarist commitment with an aggregation rule, often maximizing total welfare.
A theory can therefore be welfarist without being utilitarian.
Why the distinction matters
Once welfare is treated as central, further questions remain: should welfare be maximized, improved, distributed fairly, prioritized toward the worst off, or constrained by rights?
Those questions turn a broad welfarist commitment into a more specific theory.
A useful mental model
Think of welfarism as answering “what matters?” while a particular consequentialist theory may also answer “how should what matters be aggregated or constrained?”
This distinction is important for philosophy, welfare economics, public policy, and debates about institutional design.
