In the treatment of education, Campanella reveals himself as a seventeenth-century thinker, placing great emphasis on the study of the sciences, all of the sciences. He has a plan for spreading information on all branches of knowledge through pictures displayed throughout the city on walls and in corridors of public buildings — visual aids to education for persons of all ages. Their leaders believe that the advancement of scientific knowledge is the principal key to the betterment of the race. The report claims that those people have developed not only the telescope but also such modern inventions as power-propelled ships and flying machines.
The name Raphael, though, may have been chosen by More to remind his readers of the archangel Raphael who is mentioned in the Book of Tobit (3:17; 5:4, 16; 6:11, 14, 16, 18; also in chs. 7, 8, 9, 11, 12). In that book the angel guides Tobias and later cures his father of his blindness. While Hythlodaeus may suggest his words are not to be trusted, Raphael meaning (in Hebrew) "God has healed" suggests that Raphael may be opening the eyes of the reader to what is true. The suggestion that More may have agreed with the views of Raphael is given weight by the way he dressed; with "his cloak... hanging carelessly about him"; a style which Roger Ascham reports that More himself was wont to adopt. Furthermore, more recent criticism has questioned the reliability of both Gile's annotations and the character of "More" in the text itself. Claims that the book only subverts Utopia and Hythlodaeus are possibly oversimplistic.
