'Portraying' a proposition

Hector-Neri Castaneda claimed in several papers that a proposition expresse d by an indexical sentence (in a context of utterance) can be re-expressed by means of an oratio obliqua clause (in a sentential context) that contain s a quasi-indicator. Robert M. Adams and Rogers Albritton have presented a counter-argument that is accepted by Castaneda himself. I will argue that t he Adams/Albritton argument is not convincing. The argument uses several as sumptions which could be disputed. The paper tries to develop a more direct argument against Castaneda's central claim. If Castaneda's thesis is false , what then is achieved by quasi-indexicals in oratio obliqua? Adams and Ca staneda answer this question with a picture: the quasi-indicators could be seen as expressions that bind special sense variables to give a less metaph orical account of the functioning of quasi-indicators. Finally, I explore t he consequences of this account for iterated knowledge-ascriptions with qua si-indicators and for truth-conditional theories of meaning.
