i) Introduction
Fergus Kerr describes the issue of the book as `to show students of theology that they have much more to gain from reading Wittgenstein´s later writings than it is commonly supposed, and, secondly, that they are in a good position to understand him` (vii).

In the end of his enterprise, the postscript of the second edition left aside, he summarises the value for us: `even if I am wrong, however, the reader will have been immersed in an anthology of Wittgenstein´s texts, many of which will surely stay in the memory, whatever is to happen, after Wittgenstein, to the practice of Christian theology` (190).

These two statements are the framework of the book. In those 200 pages, Kerr introduces, what he considers, several key issues of Wittgensteinian thinking, by showing a development towards his later writings. Kerr focuses on the `philosophical investigations` (published 1951, posthumously). Here he believes to have discovered an example of how to overcome Descartes’ view on the self, that is what he thinks to be the main issue of Wittgenstein´s later writings.

First I will do a small summary (1) of the book`s structure, than I will make some brief methodological remarks (2) followed by an analysis of the most important ideas (3).

1) Summary:
Kerr starts by introducing and discussing several views of modern philosophy on the self. He realises that the starting point in all these concepts is the individual. Descartes’ heritage dominates, let me say, our views on the self, since our culture (Kerr) paradigms of knowledge are tight to ideals of impartiality and objectivity.

Kerr then (chapter 2) introduces some thoughts about language in connection with a part of Augustine´s Confessions, which forms the beginning of the Philosophical Investigations. This is the ‘warm-up` to Wittgenstein’s main issue, to deconstruct the power of the metaphysical defined self.

The second part illuminates statements of Wittgenstein´s writings,
