    Induction and Natural Kinds Revisited
    Sankey, H ; Hill, B ; Lagerlund, H ; Psillos, S (Oxford University Press, 2021)
    Howard Sankey reconsiders a special issue closely connected with causal powers—the problem of induction. He addresses a deep version of problem of circularity originally raised by Psillos, and argues that the circularity can be avoided. The key is recognizing certain epistemically externalist results of the Megaric consequences of the commitment to dispositional essentialism. Circularity can be avoided, Sankey argues, because it is the way the world is, rather than the inductive inference itself, that grounds the reliability of the inductive inference in his previous account. What are doing the work for Sankey here are the Megaric consequences of his adoption of Ellis’s dispositional essentialism. The uniformity in question is one that stretches across possible worlds: nature is uniform in the precise sense that there are natural kinds whose members all possess a shared set of essential properties. The significance of this commitment lies in how the possible and the temporal intersect through restrictions placed on the accessibility relation between the actual and the possible. Ipso facto, when considering questions about the future behaviours of objects, which is how Sankey understands the problem of induction to be, the uniformity of nature can ground the reliability of beliefs about those future behaviours precisely because the domain of possibility is restricted to those worlds accessible to the actual world, which is fixed by the commitments of dispositional essentialism.

    The Relativistic Legacy of Kuhn and Feyerabend
    Sankey, H ; Kusch, M (Routledge, 2020)
    Thomas S. Kuhn (1922–1996) and Paul K. Feyerabend (1924–1994) were central figures in the historical turn that took place in the philosophy of science in the latter half of the twentieth century. In a break with positivist orthodoxy, advocates of the historical approach sought to understand the sciences in terms of the developmental processes which underlie scientific change. With growing recognition of the extent to which science is subject to change, the suggestion that the sciences may be approached in relativistic terms came increasingly to the fore. In no small part, the work of Feyerabend and Kuhn was responsible for this trend.

    Scientific Realism and the Conflict with Common Sense
    Sankey, H ; Gonzalez, W (De Gruyter, 2020)
    The aim of this paper is to identify and resolve a tension between scientific realism and commonsense realism that arises due to a purported conflict between science and common sense. It has sometimes been held that common sense is antiquated theory which is found to be false and eliminated with the advance of science. In this paper, a distinction is proposed between three kinds of common sense: practical skill; widely held belief; basic common sense. It is agreed that common sense in the sense of widely held belief does succumb to the advance of science. It is left open to what extent practical skill varies with scientific change. It is argued that basic common sense is by and large resistant to change due to scientific change. Epistemological aspects of basic common sense are explored. A number of objections to the proposal about basic common sense are considered. It is suggested that basic common sense is sufficiently epistemologically robust to provide a foundation both for scientific knowledge and for scientific realism.
