The first half of our treatment on Ullmann can be found here, and the prelude to this two-part series can be found here (and the forerunner to the prelude [!] is here); in the six (a through e; 2a is here) parts of this second post, we’ll cover the way that his students, admirers and critics have presented the outline of his thought, and the faults they have found with it.
I mentioned Ullmann in a post about the ends of political power in Gregory the Great (Pope Gregory I) just over a month ago; I then addressed him more directly in a post about an experience of reading one of his books last week. I said that I was going to cover mostly the secondary literature on Ullmann, and this mostly by Ullmann’s students, to get a profile of the man mostly from those who knew him; originally I had intended not to look at Ullmann’s own writings much for this exercise, despite knowing that this is bad academic practice — not far from journalism.
I broke my rule, however, and looked at some of the man’s own writings. I found this passage in one of his works, describing one class of people who research “the institutional machinery of the papacy” in a way that makes their research dismissable:
remaining as they do on the surface, untouched as they are by contact with the sources, and relying as they do on secondary literature, they have little else but their own purely subjective-moral evaluations with which their presentation is interleaved. When one knows no sources, except perhaps those conveniently selected in well-known compendia, one virtually must take refuge in moralising judgements; how else is one to paint a picture? 
Perhaps it was a reader-response reaction, but I felt like the man was talking about me, to me. Below, after an initial overview, we shall survey what I have been able to uncover about Ullmann’s life, then cover the contours of his personality as it is revealed in what people have written about him.
In the next (second and final) post, we shall review the general outline of the better-known elements in the schema of Ullmann’s thought, and then review the criticisms that have been leveled against him.
