A natural view is that linguistic understanding is a source of justification or evidence: that beliefs about the meaning of a text or speech act are prima facie justified when based on states of understanding. Neglect of this view is largely due to the widely held assumption that understanding a text or speech act consists in knowledge or belief. It is argued that this assumption rests, in part, on confusing occurrent states of understanding and dispositions to understand. It is then (...) argued that occurrent states of understanding are not states of belief of knowledge since a subject may fail to believe that a text or speech act means what she understands it to mean if she doubts the reliability or truth- fulness of that understanding. States of understanding, it is maintained, belong in the same epistemic category as states of perception and memory. (shrink)

It is argued that david lewis' account of convention in "convention" required too much self-Consciousness of parties participating in a convention. In particular, It need not be known that there are equally good alternatives to the convention. This point affects other features of the definition, And suggests that the account is too much guided by the "rational assembly" picture of human conventions. (edited).

Some philosophical proposals seem to die hard. In a recent paper, Jason Stanley has worked to resurrect the description theory of reference, at least as it might apply to natural kind terms like ‘elm’ (Stanley, 1999). The theory’s founding idea is that to understand ‘elm’ one must know a uniquely identifying truth about elms. Famously, Hilary Putnam showed that ordinary users of ‘elm’ may understand it while lacking such knowledge, and may even be unable to distinguish elms from beeches (Putnam, (...) 1975). In response, Stanley claims that linguistic understanding in the case of natural kind terms comes in levels, and that only those at the top level need have the knowledge in question. The description theory, in Stanley’s hands, applies only to those with top level understanding and it is their understanding that fixes the term’s reference. To use the term successfully, those with inferior understanding need only be defer- ential to those at the top. However, Stanley’s appeal to expert knowledge fails to revive the description theory.
