On the whole throughout this project, the “meta” issue that has been raised here will be treated at three different levels of sophistication.

On the whole throughout this project, the "meta" issue that has been raised here will be treated at three different levels of sophistication.

1. The way I have chosen to deal with this issue in the present case is not by interjecting more features of the informal discussion into the dialogue of A and B, but by trying to imagine how agents like A and B might be enabled to reflect on these aspects of their own discussion.

The way I have chosen to deal with this issue in the present case is not by injecting more features of the informal discussion into the dialogue of <math>\text{A}\!</math> and <math>\text{B},\!</math> but by trying to imagine how agents like <math>\text{A}\!</math> and <math>\text{B}\!</math> might be enabled to reflect on these aspects of their own discussion.

2. In the series of examples that I will use to develop further aspects of the A and B dialogue, several different ways of extending the sign relations for A and B will be explored.  The most pressing task is to capture facts of the following sort:

A knows that B uses "i" to denote B and "u" to denote A.

B knows that A uses "i" to denote A and "u" to denote B.

Toward this aim, I will present a variety of constructions for motivating "indexed", "situated", or "extended" sign relations, all designed to meet the following requirements:
