A dialog between Donald MacKay and Mario Bunge, printed in the journal Neuroscience over the course of two years beginning in 1977, provides a conscise summary of MacKay's views on the mind-body relationship. In this dialog, MacKay contrasts the dualistic interactionism theory of Popper and Eccles with Bunge's emergentist materialism theory, and then builds a case for a third alternative based on the notion of mental events embodied in, but not identical to, brain events. Although neuroscience has made tremendous progress in the past two decades, MacKay's attempt to trace a path between interactionism and materialism is still worth considering.

The views of linguistic analysts and objectivists are explored with regard to the question of interactionism. It is argued that the admission of a logical difference between explanation by cause and explanation by motive cannot disqualify causal explanations of human action, cannot be construed as challenging the competence of science, and cannot count against interactionism. It is also argued that objectivist programs for eliminating mentalistic concepts either implicitly admit interactionism or cannot distinguish relevantly between interactionism and parallelism.

One may gather from the arguments of two of the last papers published before his death that J. L. Mackie held the following three theses concerning the mind/body problem : (1) There is a distinct realm of mental properties, so a dualism of properties at least is true and materialism false.
