Let me illustrate this with a personal example
D that I still think is pretty good
The particular experience I have in mind is that of struggling some years ago with the realisation that one lengthy part of my Ph.D should be deleted. My idea had been to combine a theological study of the work of the American theologian Hans Frei with a study of a particular congregation in Cambridge, in order to show that the concepts and arguments with which this academic theologian was working connected in interesting ways to patterns of practice and habits of thought amongst ‘ordinary’ Christians. Now my commitment to this strange combination was very strong. I put a great deal of effort into it. All sorts of people in the theology faculty, and in the congregation I was studying, knew about and supported my endeavour.
