This commentary concerns Nescolarde-Selva and Usó-Doménech’s paper on a semiotic model of ideologies. The commentary raises questions about the dynamic versus static nature of the model proposed, and in addition asks whether the model might be used to explain ethical flexibility and rigidity. The semiotic model is a mathematical one and a constructivist approach is evident. Relevance: This approach is clearly constructivist and concerns mathematical modelling of semiotics.

Key words: Constructivist approach, modelling language, ethics
