Eisenstein made a very audacious claim about the relation between printing and the Reformation, as well as the Renaissance. Luther and many contemporaries were deeply aware that they were able to stir up a cognitive and ideological revolution at least in part because of how easy it was to move their stuff around. This book is not capable of delivering an answer to the question of what’s going to happen in the next 100 years, but reading it is stimulating for thinking about that.
