Teaching Suggestions
Chapter 3 of Shaw and Barry mostly concerns three different theories of justice: the utilitarian theory, the
libertarian theory (sometimes known as the entitlement theory), and Rawls’s theory of justice. However,
before examining the three theories, it is useful to discuss the concept of justice (and how claims of
justice differ from other moral claims) and why it is important. One can also discuss with students
whether it is important to have a theory of economic justice in the first place (see Shaw and Barry’s
discussion of Walzer and of rival principles of justice).
The concept of justice is fundamental to any discussion of how society ought to be organized, and
questions of justice inevitably come up when one considers (as the introduction to Chapter 3 does) the
unequal distribution of income and wealth in the United States (and other societies). Can such disparities
be justified? In this context, you can ask students two sets of questions:
a. Can you give examples of just societies? Can you give examples of unjust societies? Why are
they unjust? What criteria do you use in determining that a society is just or unjust?
Utilitarian theory of justice: The discussion of the utilitarian concept of justice can be connected to the
discussion of utilitarianism in chapter 2 because utilitarians like Mill understand justice in terms of their
overall theory. One point to underscore is that utilitarians favor that economic system or that set of
socioeconomic rules and institutions, the adoption of which by a particular society would maximize the
overall, long-term happiness of its members. But utilitarianism itself doesn’t tell us what that economic
system is.
Applying utilitarianism to matters of justice can be illustrated in the following ways:
a. Is it unjust to sell broken TV sets without saying they are broken? No. Doing so would benefit the
seller, but not the buyers. They are likely to be deceived and lose money as a result. The benefits of the
few don’t justify even greater harm done to others. There might have been a time when “buyer beware”
was the best policy in general, but now assessing the quality of products requires expertise that buyers
can’t be reasonably required to have.
