We generally do two types of meaning theory - semantic and foundational. it is worth noting that one prominent tradition in the philosophy of language denies that there are facts about the meanings of linguistic expressions. (See, for example, Quine 1960 and Kripke 1982; for critical discussion, see Soames 1999.)

I prefer Facil's more cogent 'we might both be wrong'! Sue has just handed me a paper with the title, 'Shooting the shit: the role of bullshit in organisations' by Andre Spicer of Cass Business School. The abstract starts, 'This article argues that great deal of 'talk' and text' in organisational settings is ultimately bullshit ... produced with scant regard for truth and is used to wilfully mislead and pursue the interests of the bullshiter ... appealing on the surface but ultimately brittle'. The firm GTAT is a current example, 'yesterday a buy, today in Chapter 11 bankruptcy'.
