In the context of a critique of the exclusive use of the rational choice approach in economics, the article presents a pluralistic interpretation of the Popperian notion of situational logic as an alternative approach. This is proposed in connection with a reading of the rationality principle as a rationalisability principle. I argue that this principle can accommodate an ample array of rational responses to different situations and even rationalise the multiple responses that are given to the same situation. I present some examples to illustrate the relevance of the proposed interpretation.
