Conceptual systematization in the specialty of Family Medicine has not matched with practice. The fable is an adult education method that can serve to intuitively understand abstract concepts. In this book, brief fables are presented. Animals, vegetables, minerals and things think and speak as if they were human beings; beings or objects that are given the opportunity to think, feel and speak. Each fable is a "lesson" about "a fundamental concept of Family Medicine" and aims to make emerge, as clearly as possible, the moral of the fable, as a sobering consequence of what happened in the episode. This book can be read in two ways: 1) Forward: from the "general index" of the fables until arriving at the theoretical concept which emerges in its "moral" for each of them; and / or 2) Backward: from the "index of theoretical concepts" to the fables that illustrate them.
