Understanding and teaching pragmatism: “by their fruits ye shall know”

It is not easy to explain what pragmatism is. Everybody who has had to teach pragmatism to university students has found herself or himself in a difficult situation trying to make a clear exposition. Moreover, it was not easy for Charles S. Peirce himself to explain in a simple manner the pragmatic maxim. In this contribution, I will not go into the technicalities of the pragmatic maxim, but I will share the fruits of my reflection of many years about how pragmatism can be more easily understood and taught. The article is arranged in two parts: the first one is dedicated to the old logical rule of the gospel, “By their fruits ye shall know”, which appears in two texts of Peirce; and the second one to what I call the “logic of the kitchen”, in which I will pay attention also to Peirce’s example of the apple pie. I will add a final consideration about how to teach philosophy today, according to Peirce.
