Essence is expressed by grammar.
That's how Wittgenstein put it. It is not exactly clear what this means, which is part of the trouble. Nonetheless, I have been deeply impressed by the work of a few philosophers who have argued more determinate theses that must be understood along these lines, for example, G.E.M. Anscombe's work on the nature of intentional action, and P.T. Geach's work on the concept of goodness. My own work so far has been focussed on developing an argument that the concept of a work of art, if it has the sort of necessary connection to human goodness that has been supposed, must be analysed in terms of the form of descriptions of works of art, rather than any favored set of properties mentioned in those descriptions. 1991 B.A., University of Chicago, 1990.
