We live in a world dominated by the scientific canon that provides us with previously unknown certainties, but we also live in a certain moral perplexity and with ethical dilemmas that are not easy to resolve. Each human group shares, in principle and with internal variations, a set of values, morals and a traditional way of life. The ethnographic presentation narrative about what they appreciate, what they despise and how they verbalize it takes us to the structure of community evaluative thinking; Relationships of cooperation, dependence and evaluation of others as bearers of intention and meaning lead us to the transcendence of intersubjectivity, while weakness in cultural conformity and disdain for tradition undermine collective identity. In this new anthropological study by Carmelo Lisón Tolosana the eighth on Galicia, norm, value, obligation and law appear presented ethnographically, with the rigor, ambivalence and sophistication with which the dialoguers have transmitted them, framing everything in cases, situations and contexts, without the fetishism that surrounds much philosophy on human rights in abstract and abstruse rhetoric.
