COMMENTARY ON: Carruthers, P. (1998). Natural theories of consciousness. European Journal of Philosophy, 6(2), 203-222. http://psyche.cs.monash.edu.au/v4/psyche-4-03-carruthers.html Carruthers' case against animal consciousness employs deeply flawed reasoning and is contradicted by both empirical and introspective evidence. Although in principle we cannot objectively establish for certain that anyone -- human or otherwise -- is phenomenally conscious, results of animal research on consciousness-changing drugs are uninterpretable unless one assumes that non-human animals have discriminable subjective states. Carruthers tries to argue that higher-order thoughts are the basis of subjective experiences, but the former are derived from the latter, not the other way around. The position that only humans are conscious is reminiscent of other anthropocentric errors including outmoded notions of an Earth-centered universe created solely for humans.

This second Companion deals with the ancient theories of the psyche. The essays range over more than eight hundred years of psychological inquiry and provide critical analyses not only of the ancient discussions of the nature of the psyche and its states, but of such central topics as perception, subjectivity, the explanation of action, and what it is to be a person. In examining the wide variety of psychological theories offered by the ancient thinkers, from the increasingly complex materialism of the Presocratics and Hellenists to the dualism of Plato and Plotinus, the collection demonstrates that psychology had become a wide-ranging and sophisticated discipline long before Descartes.

One of the most influential thinkers of the 20th century, Sir Karl Popper here examines the problems connected with human freedom, creativity, rationality and the relationship between human beings and their actions. In this illuminating series of papers, Popper suggests a theory of mind-body interaction that relates to evolutionary emergence, human language and what he calls "the three worlds." Rene; Descartes first posited the existence of two worlds--the world of physical bodies and the world of mental states. Popper argues for the existence of "world 3" which comprises the products of our human minds. He examines the interaction between mental states--hopes, needs, plans, ideologies or hypotheses--and the physical states of our brain. Popper forcefully argues against the materialism forwarded by many philosophers which denies the existence of mental states. Instead, he demonstrates that the problem of the interaction between mental and physical states remains unresolved. Knowledge and the Body-Mind Problem is based on Popper's never-before published lectures at Emory University in 1969. Popper has extensively revised the lectures but has retained their accessible format. He has also incorporated some of the discussions which followed the lectures, providing an engaging exchange between the philosopher and his audience.

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.

This is a multi-disciplinary exploration of the history of understanding of the human mind or soul and its relationship to the body, through the course of more than two thousand years. Thirteen specially commissioned chapters, each written by a recognized expert, discuss such figures as the doctors Hippocrates and Galen, the theologians St Paul, Augustine, and Aquinas, and philosophers from Plato to Leibniz.
