No wonder why Giacomo Leopardi’s notebook Zibaldone (1898) is considered to be one of the most important books of the 19th century. Zibaldone is a 2,500 pages (note)book full of wisdom about art, human culture, human nature and society. The breadth of topics; the depth of understanding; fundamental impressions of things. And it is obviously written straight from the head which gives it a special charm. For example, at one point Leopardi discusses the nature of fine arts (Zibaldone 8-9). He express his doubt that “people can be judges in our time of works of fine arts.” Two sentences later, when he should elaborate more on it, he writes: “On the first question, if some thought comes to mind, I will write it down later.” In Zibaldone 14-15, Leopardi tackles the topic of Reason. As it really got me thinking about it, I will put it here in it’s entirety.
