1.2: The worries of the sceptics
Although the capability approach appeals to many readers, others have wondered whether this theory is really any different from other more established theories, or whether the capability approach is promising as a theory with sufficient bite. For example John Rawls (1999, 13), while acknowledging that the idea of basic capabilities is important, calls it “an unworkable idea” for a liberal conception of justice. John Roemer (1996, 191–93) has criticized the capability approach for being insufficiently specified — a complaint that is also echoed in the critique made by Pratab Bhanu Mehta (2009) . Others have questioned the practical significance of the capability approach for policy making and empirical assessment. For instance, Robert Sugden (1993, 1953) has questioned the usefulness of the capability approach for welfare economics — a critique to which we will return in section 4.10. In addition, at seminars and other scholarly gatherings, an often-heard criticism is that the capability approach is old wine in new bottles — it aims to do what the non-economic social sciences have been doing all along. If that is the case, then why should we bother? 5
There are two types of answer to the sceptics. The first is conceptual or theoretical and that answer will be given in the remainder of this book. In a nutshell, the reason the capability approach is worth our time and attention is that it gives us a new way of evaluating the lives of individuals and the societies in which these people live their lives. The attention is shifted to public values currently not always considered most important — such as wellbeing, freedom and justice. It is an alternative discourse or paradigm, perhaps even a ‘counter-theory’ to a range of more mainstream discourses on society, poverty and prosperity. Moreover, it brings insights from several disciplines together, and gives scholars a common interdisciplinary language. Nevertheless, it doesn’t follow that the capability approach will always offer a framework that is to be preferred over other frameworks: as this book will show, the capability approach can contribute something, but we should be careful not to overplay our hand and believe that it can do a better job for all ethical questions.
The second answer to the sceptic is empirical — to show the sceptic what difference the capability approach makes. The earlier mentioned study by Ruggeri Laderchi (1997) and dozens of similar studies do exactly that. In 2006, I provided a survey of the studies in which the capability approach had been put into practice (Robeyns 2006b) — a task that I think is no longer feasible today in a single paper or chapter, given that the empirical literature of applications of the capability approach has grown dramatically. But in order to illustrate in somewhat greater depth this kind of answer to the sceptic, let us focus on one type of empirical application of the capability approach: namely how we perceive and evaluate our lives at a macro level, and how we evaluate the social arrangements in which we live those lives.
5 Several more specific critiques on the capability approach will be discussed in chapter 4.
