Resumen:
Emilio Ribes’s essay on “Psychology as a basic science” is discussed in terms of three central propositions, around the critical analysis of the existence of a discipline with a single objective, methodology and application. The paper
proposes a collective exercise of the critical use of the language and to avoid at all cost committing categorical mistakes. Based on other contributions on behavior analysis (Harzem, 2002, 2004, 2005; Mechner, 2008), an example of the adoption of the authors’ proposal is offered.
