We analyse the implications of classical liberal and libertarian approaches for distributive justice in the context of social welfare orderings. We study an axiom capturing a liberal non‐interfering view of society, the Weak Harm Principle, whose roots can be traced back to John Stuart Mill. We show that liberal views of individual autonomy and freedom can provide consistent foundations for welfare judgements. In particular, a liberal non‐interfering approach can help to adjudicate some fundamental distributive issues relative to intergenerational justice. However, a strong relation is established between liberal views of individual autonomy and non‐interference, and egalitarian principles in the Rawlsian tradition.
