The great literature has a fundamental link with reality, without which it completely loses its educational function. It is the investigation of reality, albeit in the form of a possible reality, that makes literature broaden the reader’s horizon, making his understanding greater than that of someone who does not read. From this it is easy to see not only the importance, but also the need for the author to work on what is most strictly personal in the work. In doing so, he allows what he has been able to experience and understand individually to become, through reading, also the patrimony of his reader.
