What is the author's tone in The Adventures of Ibn Battuta, a Muslim Traveler of the Fourteenth Century by Ross E. Dunn?

The Adventures of Ibn Battuta is a scholarly work of history, and the author maintains a mostly academic, objective tone throughout the book. Many of the actions of the people described in the book, including Ibn Battuta himself, might be objectionable to the sensibilities of many modern readers, which Dunn acknowledges while attempting not to be judgmental.
