The aim of this article is to argue that ontological choices in scientific practice undermine common formulations of the value-free ideal in science. First, I argue that the truth values of scientific statements depend on ontological choices. For example, statements about entities such as species, race, memory, intelligence, depression, or obesity are true or false relative to the choice of a biological, psychological, or medical ontology. Second, I show that ontological choices often depend on non-epistemic values. On the basis of these premises, I argue that it is often neither possible nor desirable to evaluate scientific statements independently of non-epistemic values. Finally, I suggest that considerations of ontological choices do not only challenge the value-free ideal but also help to specify positive roles of non-epistemic values in an often neglected area of scientific practice.

The aim of this article is to show that externalist accounts of cognition such as Clark and Chalmers' (1998) “active externalism” lead to an explosion of knowledge that is caused by online resources such as Wikipedia and Google. I argue that externalist accounts of cognition imply that subjects who integrate mobile Internet access in their cognitive routines have millions of standing beliefs on unexpected issues such as the birth dates of Moroccan politicians or the geographical coordinates of villages in southern Indonesia. Although many externalists propose criteria for the bounds of cognition that are designed to avoid this explosion of knowledge, I argue that these criteria are flawed and that active externalism has to accept that information resources such as Wikipedia and Google constitute extended cognitive processes.

This book challenges common debates in philosophy of mind by questioning the framework of placement problems in contemporary metaphysics. The author argues that placement problems arise when exactly one fundamental ontology serves as the base for all entities, and will propose a pluralist alternative that takes the diversity of our conceptual resources and ontologies seriously. This general pluralist account is applied to issues in philosophy of mind to argue that contemporary debates about the mind-body problem are built on this problematic framework of placement problems. The starting point is the plurality of ontologies in scientific practice. Not only can we describe the world in terms of physical, biological, or psychological ontologies, but any serious engagement with scientific ontologies will identify more specific ontologies in each domain. For example, there is not one unified ontology for biology, but rather a diversity of scientific specializations with different ontological needs. Based on this account of scientific practice the author argues that there is no reason to assume that ontological unification must be possible everywhere. Without this ideal, the scope of ontological unification turns out to be an open empirical question and there is no need to present unification failures as philosophically puzzling “placement problems”.

Holism in interwar Germany provides an excellent example for social and political in- fluences on scientific developments. Deeply impressed by the ubiquitous invocation of a cultural crisis, biologists, physicians, and psychologists presented holistic accounts as an alternative to the “mechanistic worldview” of the nineteenth century. Although the ideological background of these accounts is often blatantly obvious, many holistic scientists did not content themselves with a general opposition to a mechanistic worldview but aimed at a rational foundation of their holistic projects. This article will discuss the work of Kurt Goldstein, who is known for both his groundbreaking contributions to neuropsychology and his holistic philosophy of human nature. By focusing on Goldstein’s neurolinguistic research, I want to reconstruct the empirical foundations of his holistic program without ignoring its cultural background. In this sense, Goldstein’s work provides a case study for the formation of a scientific theory through the complex interplay between specific empirical evidences and the general cultural developments of the Weimar Republic.

Elimination controversies are ubiquitous in philosophy and the human sciences. For example, it has been suggested that humanraces, hysteria, intelligence, mental disorder, propositional attitudes such as beliefs and desires, the self, and the super-ego should beeliminated from the list of respectable entities in the human sciences. I argue that eliminativist proposals are often presented in theframework of an oversimplified ‘‘phlogiston model’’ and suggest an alternative account that describes ontological elimination on a gradualscale between criticism of empirical assumptions and conceptual choices
