Not really a novel, more a series of notes and observations on life wrapped up in the story of a boy growing to manhood. Lots here to mine if you are, or intend to be, a writer.
Whatever else this book is, it does not qualify as a novel because the plot is only an excuse for Butler to put out his views on dozens of moral, philosophical, scientific and artistic ideas and topics - The Way of All Flesh suggested by his brilliant choice of title. There were passages at which I laughed out loud, and others that superbly deconstruct some of life's familiar set pieces. Elsewhere Butler simply dissolves into a rant, or strays off the point.
The plot concerns Ernest, born the son of a priggish minister and his weak wife, his childhood at home, his schooling and education at Cambridge. He is ordained, imprisoned, married (to a bigamist drunkard), inherits and finally finds happiness as a writer. It's all too much, and the plot machinery doesn't engage properly in the second half of the book. The device of having the narrator act as a central character does a lot of damage to pace and credibility.
However, the plot is not really important. Instead Butler gives out a stream of witty and thoughtful consciousness. He is very, very good at exposing how the weak prey upon the weaker. Anyone who works in a major corporation, or similar, will recognise instantly the behaviour of Ernest's parents as they try to keep him in his place. And their letters to Ernest could easily be modern internal memos. Butler has a very sharp eye and ear for uncovering and delightfully exposing humbug. Unfortunately, he doesn't always know when enough is enough and a thorough editing would have made the text much sharper. There are pages and pages about various religious differences for example that come down to a rant. It's a bit like talking to a daft old uncle - good fun but not coherent.
Nonetheless, Butler as a writer is well read, thoughtful, knowing and has obvious human empathy. If you are, or have aspirations to be, an author you should read this book - and take copious notes.
