Tim Adams at The Guardian:
Gray never bought the idea that his book was a handbook for despair. His subject was humility; his target any ideology that believed it possessed anything more than doubtful and piecemeal answers to vast and changing questions. The cat book is written in that spirit. If like me you read with a pencil to hand, you will be underlining constantly with a mix of purring enjoyment and frequent exclamation marks. “Consciousness has been overrated,” Gray will write, coolly. Or “the flaw in rationalism is the belief that human beings can live by applying a theory”. Or “human beings quickly lose their humanity but cats never stop being cats”. He concludes with a 10-point list of how cats might give their anxious, unhappy, self-conscious human companions hints “to live less awkwardly”. These range from “never try to persuade human beings to be reasonable”, to “do not look for meaning in your suffering” to “sleep for the joy of sleeping”.
