  The broad concept of an individual's welfare is actually a cluster of related
specific concepts that bear a "family resemblance" to one another. One might
care about how a policy will affect people both in terms of their subjective
preferences and also in terms of some notion of their objective interests. This
paper provides a framework for evaluation of policies in terms of welfare
criteria that combine these two considerations. Sufficient conditions are
provided for such a criterion to imply the same ranking of social states as
does Pareto's unanimity criterion. Sufficiency is proved via study of a
community of agents with interdependent ordinal preferences.
