Anomalous Monism - Overview

Overview

Considering views about the relation between the mental and the physical as distinguished first by whether or not mental entities are identical with physical entities, and second by whether or not there are strict psychophysical laws, we arrive at a fourfold classification: (1) nomological monism, which says there are strict correlating laws, and that the correlated entities are identical (this is usually called type physicalism); (2) nomological dualism, which holds that there are strict correlating laws, but that the correlated entities are not identical (parallelism and pre-established harmony); (3) anomalous dualism, which holds there are no laws correlating the mental and the physical, and that the substances are ontologically distinct (i.e. Cartesian dualism); and (4) anomalous monism, which allows only one class of entities, but denies the possibility of definitional and nomological reduction. Davidson put forth his theory of anomalous monism as a possible solution to the mind-body problem.

Since (in this theory) every mental event is some physical event or other, the idea is that someone's thinking at a certain time, for example, that snow is white, is a certain pattern of neural firing in their brain at that time, an event which can be characterized as both a thinking that snow is white (a type of mental event) and a pattern of neural firing (a type of physical event). There is just one event that can be characterized both in mental terms and in physical terms. If mental events are physical events, they can at least in principle be explained and predicted, like all physical events, on the basis of laws of physical science. However, according to anomalous monism, events cannot be so explained or predicted as described in mental terms (such as "thinking", "desiring" etc.), but only as described in physical terms: this is the distinctive feature of the thesis as a brand of physical monism.
