DEMARCATION
Philosophy of science is concerned with the assumptions, foundations, methods, implications of science, and with the use and merit of science.
Demarcation
The demarcation problem in the philosophy of science is about how to distinguish between science and nonscience, and more specifically, between science and pseudoscience (a theory or method doubtfully or mistakenly held to be scientific). The debate continues after over a century of dialogue among philosophers of science and scientists in various fields, and despite broad agreement on the basics of scientific method.
The demarcation problem is the philosophical problem of determining what types of hypotheses should be considered scientific and what types should be considered pseudoscientific or non-scientific. It also concerns itself with the ongoing struggle between science and religion, in particular the question about which elements of religious doctrine can and should be subjected to scientific scrutiny. This is one of the central topics of the philosophy of science, and it has never been fully resolved.
The Purpose of Demarcation
Demarcations of science from pseudoscience can be made for both theoretical and practical reasons. From a theoretical point of view, the demarcation issue is an illuminating perspective that contributes to the philosophy of science.
From a practical point of view, the distinction is important for decision guidance in both private and public life. Since science is our most reliable source of knowledge in a wide variety of areas, we need to distinguish scientific knowledge from its look-alikes. Due to the high status of science in present-day society, attempts to exaggerate the scientific status of various claims, teachings, and products are common enough to make the demarcation issue pressing in many areas. The demarcation issue is therefore important in many practical applications such as the following:
