The concept of approximate truth plays a prominent role in most versions of scientific realism. However, adequately conceptualizing ?approximate truth? has proved challenging. This article argues that the goal of articulating the concept of approximate truth can be advanced by first investigating the processes by which science accords theories the status of accepted or rejected. Accordingly, this article uses a path diagram model as a visual heuristic for the purpose of showing the processes in science that are involved in determining (...) a theory's status. This ?inductive realist? model of theory status then serves as a starting point for explicating an inductive realist view of approximate truth that, it is argued, can explain instances of the success of science, but does not (1) require science's theories to be strictly true in any world or (2) require a metric for measuring how close an approximately true theory is to some strictly true theory. To show the advantages of the inductive realist approach to approximate truth, an example of a major success story of science, the successful eradication of smallpox, is reviewed and then explained.

Our aim is to explore and develop notions of objectivity that are useful and appropriate for critical realist empirical research. Part I explores the values associated with objectivity, Part II the linkages between objectivity and situated action. The introductory section of Part I explains why it is worthwhile in realist terms to develop the notion of objectivity; that is, develop it as opposed to remaining content with murky hidden notions or connotations that the term ‘objectivity’ brings to mind and that (...) tend to cause confusion in how it is accepted and rejected. This is important as a clarification exercise for social research. In Part II, we argue that the growth of knowledge requires engagement and critical analysis. We develop the idea that if subjects are engaging objectively with reality and its multiple standpoints, then the results will tend to be transformative. Again, our aim is to be of use to practical researchers by providing underlying arguments. Specifically, we argue that objectivity is a bridge between the subjectivities of subjects and the rest of the real world. (shrink)

Critical realists offer a set of philosophical underpinnings for social research. Critical realists also engage constructively with social theory, but they are more than just theorists. In this chapter I list and describe various innovative methodological contributions made in recent years by realists. I point out ways in which research methods (i.e. techniques) fit with particular methodological assertions. There is a historical legacy of empiricism which critical realists often use as a foil to make their own position more clear. However, (...) among realists, a wide variety of methods are used, and the range of realist methodological assumptions is wider than one might expect because of their efforts to work with social theory.The introduction to the chapter covers ontology as it relates to research methods. The second section of the review introduces retroduction, a major methodological starting-point common to most realists. The third section reviews concretely the realist debate over statistics and some realist contributions to qualitative methodology, qualitative methods, and action research as used by realists. The fourth section takes up the challenge of realist claims about knowledge (debates usually known as epistemology). An important aim in this chapter is to argue that 'factual' statements usually embody layers of meaning, and thus are contestable; that enquiry using quantitative methods can coherently be done from a realist perspective; and that among realists qualitative enquiry is a broad and useful set of methods which have made genuine innovations in methodological knowledge. Meta-critique and pluralism are widely-used realist contributions to the methods tool-basket in social science, and the realist approach to social statistics is a much better guide to how statistics is, in practice, done than any currently available empiricist quantitative textbook (Ron, 2002). However 'quantitative' research always rests upon conceptual, theoretical and qualitatively derived frameworks and therefore is derived from qualitative work, whereas the converse is not true; qualitative research does not require any quantitative research. In the current scene, mixed methods also play a key role as a growing area of research methods. In this way, within sections one and two, the reader is given an overview of Volume 1 of this collection. Sections two and three of this chapter review Volumes 2 and 3 (realist methods, and empirical examples, respectively). Section four reviews the epistemological theme that is at the core of Volume 4. This introduction thus roughly parallels the contents of the rest of the volumes. (shrink)
