The original Spanish text gave the etymology of cuidado which derives from the Latin roots cogitatus, thought, the participle of cogitare, and agitare, to agitate or trouble (Gomez de Silva, 1998 and Robert, 1979 in Flores-Castillo, 2012). In Spanish, as in several other Romance languages, therefore, the word for care is etymologically related to thinking, caring, care and curing. It is considered to be a regulatory component, expressed in terms of self-knowledge and skill in the quest for the principles of truth, which can encompass such widely diverse spheres as death, illness, suffering and political life, and, by the same token, judgement as to the value of the actions that the individual carries out (Foucault, 2005). Care of oneself is knowledge of self and the compilation of a certain number of rules of behaviour or principles which are at the same time truths and prescriptions: thus ethics and the game of truth are linked.
