What is the author's tone in New Atlantis ; and, the Great Instauration by Francis Bacon?

The Great Instauration has three primary tones: that of a relatively dry philosophy text, that of an extended negative criticism of the practices of the day, and that of a hopeful text meant to produce hope for the future of humanity.

The tone of The New Atlantis reflects the attitude of the narrator, the sailor whose crewmates he finds Bensalem with. Initially the sailor is bewildered by getting lost at sea and discovering such an advanced civilization unknown to the rest of the world. However, he quickly warms to the Bensalemites and becomes curious about their culture. As the book wears on, the sailor's tone becomes brighter and more hopeful as he learns more and more about the greatness of Bensalem.
