Beckett's real one was less effusive. He saw how nature has 'a calm, secret hostility' inflicting intense pain and suffering on loved ones with pause only for what we call life. It is nothing to be celebrated. So, it is no surprise that 'Dream of Fair to Middling Women', the novel Knowlson and Cronin mine most heavily for information, is only available because of the author's death. He did not want it published during his lifetime because it was too clever and derivative.
Cleverness tends to be derivative.
As one critic said, Beckett 'had a lot to unlearn'. However, such bad art enables Knowlson and Cronin to present convincing portraits of Beckett in young adulthood. Cronin is particularly dismissive of a lot of Beckett's early itching. This is refreshing after the uncritical, if not also hagiographical tone taken by Knowlson, Beckett's long time friend. One thing Cronin didn't have that Knowlson did was access to Beckett's diaries from his wander around Nazi Germany in the Thirties.
