What is the author's tone in The Puritan Dilemma; the Story of John Winthrop by Edmund Sears Morgan?

The tone of The Puritan Dilemma has three primary shades: neutral, admiring, and critical. The Puritan Dilemma is a work of history so, for the most part, it relates facts in an impartial fashion, only commenting from time to time on ideas and beliefs that are relevant to informing the narrative. This is not to say that the book is not written in an engaging fashion, however. However, the primary tone of the book is that of a work of history—it strives to have a scholarly, neutral tone that relates facts as much the way historians think they were as the author is capable of.
