Abstract
The current work is dedicated to lesion and beings that are its functional equivalents. The study encompasses no less than five parts. The Introductory Speech is followed by a Part that presents the French, Québécois, and Louisianian lesions; the three entities are also compared. Some remarks on lesion’s foundation and the concepts that explain it are contained in the same Part. The third Part looks at unconscionability and places it face to face with lesion. Part IV embraces lesion’s other functional equivalents. The fifth and last Part includes the Final Observations.
