Whether translating research findings for public consumption, or arguing for a policy position that reflects social work values, social workers engaged in cause advocacy need rhetorical skills. The author draws from the disciplines of linguistics, logic, and communications and provides a framework for making arguments in the public arena. The structure and components of arguments are analyzed, and strategies for choosing persuasive empirical evidence and using values to support an argument are described. The use and misuses of language are discussed. Excerpts from published op-ed pieces are used for illustration.
