Insincerity is the intentional conflict between a state of mind and a synchronic linguistic act. Three cases have to be distinguished: lying, as the opposition of belief and assertion (the act is untruthful); dishonesty, as the opposition of will and declaration of will (act empty); and simulation, as the opposition of emotion and exclamation (act ungenuine). One of the problems arising is: Are there insincere commands, and if not, why?Disloyalty, on the other hand, is a diachronic inconsequence, the breach of (...) a linguistic action (act unredeemed) which was binding for the future (such as, e.g. a promise). There is a cross-connection to dishonesty, which can be seen as the will to be disloyal. (shrink)
