  1. Reduction

    In philosophy, reduction is the process by which one object, property, concept, theory, etc., is shown to be explicable in terms of another, lower level, entity. In particular, a concern of philosophy is as to the scope of physical theory, and whether, for example, all events are ultimately physical events, a discussion closely related to the topic of causal closure. In science, such reduction is generally desirable, because it explains why and how the thing which is being reduced exists, and because it promotes conceptual and theoretical economy. Reducing chemical properties to properties of atoms thus explains these properties and integrates them into a single explanatory framework, that of atomic structure. For example, we say that physical properties such as the boiling point of a substance are reducible to that substance’s molecular properties, because statistical mechanics explain why a liquid boils at a certain temperature using only the properties of its constituent atoms. Thus we might also describe reduction as a process analogous to absorption, by which one theory is wholly subsumed under another. Reductionism can be divided into three general areas – methodological, theoretical, and ontological – and reduction into two – theoretical and ontological.
