Full Idea
I attribute three properties to the indexical perspective: it is subjective, incorrigible, and constant.

A Reaction
That is as good an idea as any for summarising the view (associated with John Perry) that the indexical perspective is an indispensable feature of reality. For a good attack on this, which I favour, see Cappelen and Dever.
