What does the author mean by ‘tremulations on ether’ and ‘the novel as a tremulation’?

By saying ‘tremulations on ether’ the author means to say that most books are like messages or news being read on the radio. One can hear them, feel sorry or happy about a specific piece of news for some time. But one can never identify with the news. Whereas ‘the novel as a tremulation’ is a multi-dimensional review of the characters of the novel. Through the deeds of the characters a reader can understand what needs to be done and what needs to be avoided in life. It actually gives the reader an insight into the crucial moments of life without actually having to experience them. In that way, a person can mould his or his decisions and grow well.
