On your advice, I will locate and read it. ;^)
As such I found the book read easier when imagining a professor fully absorbed and animated in presenting his theses.
Imagine arm movements, eyebrow arches, grins and grimaces, rise and fall in tempo and volume. Doing this you may find it easier to read than did I the first time. His apparently repetitive examples, probably used to get across the essence of his meanings with as little uncertainty as possible, then becomes more enlivening and understandable. I imagine it must've been a kick hearing it.
