Empirical evidence of self-deception's propositional duality is not sought; philosophically relevant links between propositions proper and mind are explored instead. Speech in unison ably indicates the social grounding of such attitudinal structures. An extra-theoretical eye – with regard to cognitivism – is cast on a case of “illusory communication.” The reinforcing of lexical analysis shows Mele's approach to be in need of non-ego concepts, wherefore it lacks soundness with respect to reference.

Erroneously attributing propositional attitudes (desires, beliefs...) to computational artefacts has become internationally commonplace in the public arena, especially amongst the new generation of non-initiated users. Technology for rendering machines “user-friendly” is often inspired by interpersonal human communication. This calls forth designers to conceptualise a major component of human intelligence: the sense ofcommunicability, and its logical consequences. The inherentincommunicability of machines subsequently causes a shift in design strategy. Though cataloguing components of bouts between person and machine with Speech Act Theory has (...) been popular, I will endeavour to present thesine qua non for their insertion into a larger unit of discourse — their societal embodiment. I shall argue that the so-called “intelligence” of the artificial should to be seenas a purposeful act that is socially generated, because it comes of Man,for Man. Designership will provide the forum for evolving user requirements and interface renewal. (shrink)
