Psychologist Martin Seligman’s Flourish is a strange book, in that it does not deliver on any of its promises, and yet somehow remains enjoyable. You would be forgiven for assuming, given the book’s rather bold opening that “This book will help you flourish,” that the book will in fact help you flourish—which it does, sort of. The early chapters, after promising then not delivering many practical exercises, then seem to imply that the book will instead summarise developments of positive psychology beyond its original scope of “authentic happiness”—which it does, sort of. The rest is part intriguing memoir, part summary of where psychology and philosophy went wrong in the twentieth century, and part discussion of the military and education. If this sounds like a strange mixture, it is. And yet the writing remains engaging, and the book does actually give some practical advice about how to incorporate gratitude, better listening skills, and activities which are orientated towards character strengths and accomplishment, into one’s life. Because of what appears to be a lack of editorial guidance, going into it with expectations to learn anything specific is likely to lead to disappointment. But if you pick it up, as I did, with an open mind no expectations, you may find quite a few provocative facts and perspectives.
