We agree with Rachlin's aim to account for altruism within existing theory. However, his argument is implicitly dependent on social and cognitive constructs that are explicitly identified in other social-psychological theories. The account does not advance theory beyond available constructs (e.g., self-categorizations, motives, values, role-identities, and social structure), and Rachlin's implicit use of these strains the behaviorist account.
