"I see a crow" - los límites de Avicena y el Apocalipsis Animal

It should perhaps best be left an open question whether it is a necessary prerequisite of understanding this proposition that the addressee conceives for herself what the proposition 'I saw a crow' means, i.e. understands the third personal proposition on the basis of her first personal experience of what it means to see a crow. The question is huge and difficult, and one in the analysis of which Avicenna may eventually not be of any great help.
