Definitions of ‘pseudoscience’ are required to heed the established usage of the definiendum by subsuming those cases that are generally considered to be pseudoscientific, and by excluding those that are considered sciences. In this paper I sample the published record to assess the consensus on pseudoscience case classifications. The review finds inconclusive evidence for an overall agreement. However, the frequent usage of a small number of pseudoscience-cases indicates that these are considered paradigms of pseudoscience. I briefly discuss some practical implications (...) of these findings for the pseudoscience demarcation project. (shrink)

This paper reviews how research on the demarcation problem has developed, starting from Popper’s criterion of falsifiability and ending with recent naturalistically oriented approaches. The main differences between traditional and contemporary approaches to the problem are explicated in terms of six postulates called the traditional assumptions. It is argued that all of the assumptions can be dismissed without giving up on the demarcation problem and that doing so might benefit further discussions on pseudoscience. Four present-day research movements on evaluating the (...) boundaries of science are introduced: (1) philosophy of pseudoscience, (2) social epistemology of dissent, (3) agnotology, and (4) evaluation of expertise. Researchers working within these areas have abandoned some or all traditional assumptions. (shrink)

In this book, I defend the present-centered approach in historiography of science (i.e. study of the history of science), build an account for causal explanations in historiography of science, and show the fruitfulness of the approach and account in when we attempt to understand science. -/- The present-centered approach defines historiography of science as a field that studies the developments that led to the present science. I argue that the choice of the targets of studies in historiography of science should (...) be directly connected to our values and preferences in an intersubjective process. The main advantage of this approach is that it gives a clear motivation for historiography of science and avoids or solves stubborn conceptual and practical problems within the field. -/- The account of causal explanations is built on the notions of counterfactual scenarios and contrastive question-answer pairs. I argue that if and only if we track down patterns of counterfactual dependencies, can we understand history. Moreover, I define the notions of historical explanation, explanatory competition, explanatory depth, and explanatory resources. -/- Finally, I analyze the existing historiography of science with the framework built in the previous chapter, and I show that this framework clarifies many first-order (i.e. concerning the history of science) and meta-level issues (i.e. concerning the nature of science in general) that historians and philosophers tackle. As an illustration of the philosophical power of the framework, I explicate the notion of local explanation and analyze the question of whether the developments of science were necessary or contingent.
