What is the author's tone in the nonfiction book, War in Val D'Orcia, 1943-1944?

The tone of the diaries is defined more by its focus on events than on reflection, and by its consideration of activities and situations of others rather than on those of the writer. This is, perhaps, unusual for diaries which, in general and almost by definition, are devoted more to considerations of the writer than of others. In the case of this particular diary, however, considerations of self run somewhat deeper than an initial consideration might suggest. In other words, the tone of the diary is reflective of its themes, and vice versa, reflecting its writer's selfless perspective on the value and necessity of assisting humanity in times of need. It is at times objective and at other times entirely subjective. Ultimately, the diary is an intriguing, and engaging, tonal mix of the politely horrified and the equally politely passionate, of matter of fact distaste and equally matter of fact determination. While this approach may not entirely engage the reader's emotion (it could be argued, in fact, that as a diary it was never really intended to do so, the book effectively creates and defines a clear picture of the tensions between two fundamentally different philosophies on human existence as manifest in the life and experience of a single individual. It's important to note, meanwhile, that in doing so, the book clearly asks the reader to consider whether s/he would do as that human being did.
