Abstract
This article is the fourth exchange in a discussion between Jamin Carson and David Elkind regarding constructivism and objectivism. Throughout the debate, which has been published exclusively in The Educational Forum (Elkind 2004, 2005; Carson 2005a), Elkind has maintained that constructivism is the best educational philosophy, that it is not relativistic, and that social consensus is the standard of truth. Carson, on the other hand, has argued that constructivism and social consensus are both logically self-refuting and relativistic, and that unless education is based on objective standards of truth—sense experience and reason—education is meaningless.
