    The previous chapter listed a range of fields in which the capability approach has been taken up, and in chapters 3 and 4 we focus in more detail on how the capability approach can (or cannot) make a difference for thinking about wellbeing, social and distributive justice, human rights, welfare economics and other topics. This broad uptake of the capability approach across disciplines and across different types of knowledge production (from theoretical and abstract to applied or policy oriented) is testimony to its success. But how is the capability approach understood in these different fields, and is it possible to give a coherent and clarifying account of how we can understand the capability approach across those fields?1 In other words, how should we understand the capability approach as an overarching framework, that unites its more specific uses in different fields and disciplines?

    This chapter gives an account of that general framework. It provides explanations and insights into what the capability approach is, what its core claims are, and what additional claims we should pay attention to. This chapter will also answer the question: what do we mean exactly when we say that the capability approach is a framework or an approach?

    In other words, in this chapter, I will give an account (or a description) of the capability approach at the most general level. I will bracket additional details and questions about which disagreement or confusion exists; chapter 3 will offer more detailed clarifications and chapter 4 will discuss issues of debate and dispute. Taken together, these three chapters provide my understanding of the capability approach.

    Chapter 2 is structured as follows. In the next section, we look at a preliminary definition of the capability approach. Section 2.3 proposes to make a distinction between ‘the capability approach’ and ‘a capability theory’. This distinction is crucial — it will help us to clarify various issues that we will look at in this book, and it also provides some answers to the sceptics of the capability approach whom we encountered in the previous chapter. Section 2.4 describes, from a bottom-up perspective, the many ways in which the capability approach has been developed within particular theories, and argues why it is important to acknowledge the great diversity within capabilitarian scholarship. Sections 2.5 to 2.11 present an analytic account of the capability approach, and show what is needed to develop a particular capability theory, application or analysis. In 2.5, I propose the modular view of the capability approach, which allows us to distinguish between three different types of modules that make up a capability theory. The first, the A-module, consists of those properties that each capability theory must have (section 2.6). This is the non-optional core of each capability theory. The B-modules are a set of modules in which the module itself is non-optional, but there are different possible choices regarding the content of the module (section 2.7). For example, we cannot have a capability theory or application without having chosen a purpose for that theory or application — yet there are many different purposes among which we can choose. The third group of modules, the C-modules, are either non-optional but dependent on a choice made in the B-modules, or else are completely optional. For example, if the purpose you choose is to measure poverty, then you need to decide on some empirical methods in the C-modules; but if your aim is to make a theory of justice, you don’t need to choose empirical methods and hence the C-module for empirical methods (module C3) is not relevant for your capability application (section 2.8).2 In the next section, 2.9, I discuss the possibility of hybrid theories — theories that give a central role to functionings and capabilities yet violate some other core proposition(s). Section 2.11 rounds up the discussion of the modular view by discussing the relevance and advantages of seeing the capability approach from this perspective.

    Section 2.12 summarises the conceptual aspects that have been explained by presenting a visualisation of the conceptual framework of the capability approach. Section 2.13 uses the modular view to illuminate the observation, which has been made by several capability scholars, that the capability approach has been used in a narrow and in a broad sense, and explains what difference lies behind this distinction. In the broader use of the capability approach, supporting or complementary theories or additional normative principles are added to the core of the approach — yet none of them is itself essential to the capability approach. These are choices made in B-modules or the C-modules. The modular view of the capability approach that will be central to this chapter can thus help to formulate in a sharper manner some observations that have already been made in the capability literature. The chapter closes by looking ahead to the next chapter.


    1 In developing the account of the capability approach as presented in this book, I have started in an inductive way by trying to generalize from how the capability approach has been used in the literature. However, that literature has been critically scrutinized, and in some cases I have come to the conclusion that some ideas in this broad ‘capabilities literature’ do not survive careful analysis, and should be rejected. Put differently, my methodology has been to be as inclusive as possible, but not at the cost of endorsing (what I believe to be) confusions or errors.

    2 To the reader who finds this ultra-brief summary of the modular account of the capability approach here unclear: please bear with me until we have reached the end of this chapter, when the different modules will have been unpacked and explained in detail.
