While medicine is solidly grounded on scientific areas such as biology and chemistry, some argue that it is in its essence not a science at all. With medicine playing a substantial societal role, addressing questions about the scientific nature of medicine is of obvious urgency. This paper takes on such a task and starts by consulting the literature on the “demarcation” problem in the philosophy of science. Learning from failures of earlier approaches, it proposes that we adopt a Deflated Approach, (...) which acknowledges that “science” is a family resemblance concept that admits differences of degrees to nonscientific undertakings. Then, drawing on Paul Hoyningen-Huene’s ; account of systematicity and Alexander Bird’s analysis of examples from the history of medicine, the paper argues that medicine meets the requirement for systematicity on all dimensions and thereby qualifies as a science. The paper then considers and defuses two objections. First, it is shown that nonepistemic differences linked to the distinctive duality of medicine do not warrant thinking that medicine is not science. Second, against some recent criticism, the paper uses homeopathy as an example to show that systematicity can succeed as a demarcation criterion. (shrink)

Then, drawing on Paul Hoyningen-Huene’s (Systematicity: The nature of science, Oxford University Press, Oxford, 2013); (Synthese 196: 907–928, 2019) account of systematicity and Alexander Bird’s (Synthese 196: 863–879, 2019) analysis of examples from the history of medicine, the paper argues that medicine meets the requirement for systematicity on all dimensions and thereby qualifies as a science. The paper then considers and defuses two objections. First, it is shown that nonepistemic differences linked to the distinctive duality of medicine do not warrant thinking that medicine is not science. Second, against some recent criticism (Oreskes in Synthese 196: 881–905, 2019), the paper uses homeopathy as an example to show that (synchronic and diachronic) systematicity can succeed as a demarcation criterion.

The problem of demarcating science from nonscience remains unsolved. This article executes an analytical process of elimination of different demarcation proposals put forward since the professionalization of the philosophy of science, explaining why each of those proposals is unsatisfactory or incomplete. Then, it elaborates on how to execute an alternative multicriterial scientific demarcation project put forward by Mahner. This project allows for the demarcation not only of science from non-science and from pseudoscience, but also of different types of sciences and (...) of scientific fields from each other. This article also offers arguments in favor of accepting two types of scientific demarcations, namely epistemic-warrant scientific demarcations and territorial scientific demarcations, and argues in favor of accepting a territorially broad scientific demarcation.
