The first and last paragraphs should give you the gist (and I think it's OK for me to reproduce them here):
Rupert Read's new book argues that the so-called social sciences ought to be understood as social studies instead. At least, this is how the book is likely to be read, despite Read's insistence that he is not really arguing so much as he is providing reminders to help the reader decide for herself whether the social sciences are best thought of as genuine sciences. He does this in two stages. In the first, he makes the case that Kuhn is not the relativist he is often taken to be and can usefully be thought of as a Wittgensteinian philosopher. In the second, he goes through one social science, or group of social sciences, after another in order to question their status as sciences and to suggest that they are actually more philosophical than is generally recognised. The book also includes lecture transcripts, an “inter-section,” and an interview with Read conducted by Simon Summers, but the bulk of the book consists of “Part 1: Wittgenstein, Kuhn and Natural Science” and “Part 2: Wittgenstein, Winch and ‘Human Science’.”
Is economics therefore not a science? Well, as Read somewhat surprisingly does not dwell much on, it depends what you mean by science. If some economists, for instance, seem to want to claim something false about their discipline by calling it a science, one response is to contradict them. Read leaves it to the reader to decide what to say, but it is clear enough where his sympathies lie. Another approach, however, is to agree with the economist and to be more liberal with what is called a science. Terms such as “scientia” and “Wissenschaft” (as Read notes) have a wide scope, after all, wide enough to cover philosophy (although he rejects calling philosophy science as “a disastrous and self-deceptive manoeuvre” on page 130). As Wittgenstein and Read might say, we can say what we choose, so long as it does not prevent us from seeing the facts. And Read's rich work presents a great many facts and insights that do indeed incline the reader to see much of the social sciences as infected with scientism.
