According to Bi-logic theory, there are two logics operating in the mind. One is traditional logic, and the other one is called “symmetrical”, because it does not respect asymmetrical relations. Bi-logic assumes that mental processes involve combinations of both logics in different proportions. From that perspective, Michael Gilbert’s theory of Multi-Modal argumentation is discussed focusing upon emotional arguments. It is claimed that these arguments are bi-logical, that is, they contain a combination of traditional and symmetrical logics
