In this article I will show why and how it is useful to exploit the hexagon of opposition to have a better and new understanding of the rela- tionships between morality and violence and of fundamental axiological concepts. I will take advantage of the analysis provided in my book Under- standing Violence. The Intertwining of Morality, Religion, and Violence: A Philosophical Stance. Springer, Heidelberg/Berlin, 2011 to stress some aspects of the relationship between morality and violence, also reworking some ideas by John Woods concerning the so-called epistemic bubbles, to reach and describe my own concept of moral bubbles. The study aims at providing a simple theory of basic concepts of moral philosophy, which extracts and clarifies the strict relationship between morality and vio- lence and more, for example the new philosophical concept of overmoral- ity. I will also conclude that this kind of hybrid diagrammatic reasoning is a remarkable example of manipulative explanatory abduction —through drawing—in the spirit of “conceptual structuralism”, promoted by Robert Blanch´ e and further developed by Jean-Yves B´ eziau.

Moral Philosophy through Drawing is Easy It is well-known that in the case of the hexagon the idea is to draw a triangle dual to the triangle of contrariety, constructed by considering the opposed corners (in the sense of contradictory opposition). This originates a triangle of subcontrariety and putting the two triangles together we get a hexagon in which we find back the square. The quantificational hexagon is the fruit of a generalization of this construction in an abstract structure defining the Y -corner of the triangle of contrariety as the conjunction of the I and the O
