An author from the age of reason would write a book where the main topic would be greed, but he would do it in a very different manner from the modernist author, although the topic is relatively the same. This first author would write about greed, but only to present its bad sides, to say how and why greed is bad. Whereas a modernist author would talk about the same topic with the view to creating a society that knows no such sin, that is completely cleansed from it.
