Professional involvement and the moral life of individuals and professional groups, especially those with high social prestige, such as firefighters, are linked by the category of “ethos”. Since the ethos of this service is today significantly influenced by multifaceted and dynamic ideological and existential transformations, it seems necessary to analyse the nature of this impact. Therefore, it seems that postmodernity brings with it ideological tendencies, which, by destroying the traditional preferences established so far, do not propose anything in their place. (...)
