The paper distinguishes between epistemic and ontic divisions of qualities into primary and secondary. It identifies two functions which ontic division has been called upon to fulfill - setting the limits on what a realist philosophy of science must achieve, And providing a means of judging between rival realist philosophies of science. It argues for an interaction pattern criterion of primacy, And concludes that while this enables the first function to be achieved, No primary/secondary distinction can fulfill the second.

This paper considers the impact which developments in neuroscience seem likely to have on our inherited, intuitive psychology ‐ the system of beliefs called ‘folk psychology’ by enthusiasts for its elimination. The paper argues that while closer relations between a developing genuinely scientific cognitive psychology and a burgeoning neurological understanding are to be welcomed, physiology will not reduce psychology, and the concepts belonging to intuitive psychology will be transformed and enriched, but not discredited or discarded, when psychology, in its cognitive form, emerges as a science with genuine explanatory power. The analogy between belief and desire, on one hand, and witches and phlogiston, on the other, is rejected. So is the parallel between folk psychology and folk physics. We face the choice, on Churchland's principles, between the rejection of historical, literary, and moral culture, and accepting a dualism in human thought which despairs of a comprehensively naturalistic vision of ourselves.

D. M. Armstrong is an eminent Australian philosopher whose work over many years has dealt with such subjects as: the nature of possibility, concepts of the particular and the general, causes and laws of nature, and the nature of human consciousness. This collection of essays explores the many facets of Armstrong's work, concentrating on his more recent interests. There are four sections to the book: possibility and identity, universals, laws and causality, and philosophy of mind. The contributors comprise an international group of philosophers from the United States, England and Australia. An interesting feature of the volume is that Armstrong himself has written responses to each of the essays. There is also a complete bibliography of Armstrong's writings.

Epiphenomenalism is a theory concerning the relation between the mental and physical realms, regarded as radically different in nature. The theory holds that only physical states have causal power, and that mental states are completely dependent on them. The mental realm, for epiphenomenalists, is nothing more than a series of conscious states which signify the occurrence of states of the nervous system, but which play no causal role. For example, my feeling sleepy does not cause my yawning — rather, both the feeling and the yawning are effects of an underlying neural state.
