Note: Paper to appear in special issue of the journal Psychology of Consciousness: Theory, Research, and Practice, on the evolution of consciousness //// Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness (...) of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in press) was limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

Interest in the notion of the possible financial sacrifice suffered by socially responsible investment (SRI) fund investors for considering ethical, social and environmental issues in their investment decisions has spawned considerable academic interest in the performance of SRI funds. Both the Australian and international research literature have yielded largely mixed results. However, several of these studies are hampered by methodological problems which can obscure the significance of reported results, such as the use of small sample sizes, inconsistencies in the time (...) frames selected to analyse performance and different modelling frameworks used to estimate investment returns. This study attempts to redress some of these issues by investigating the returns performance of 89 ethical funds in Australia over the period 1986-2005. Using a multi-factor CAPM model [Fama, E. F., and K. R. French (1996) J. Finance 51(1), 55] (which controls for factors such as size, book-to-market value and momentum) we find that ethical funds significantly under-perform the market in Australia, particularly in the most recent 5 years of our sample period (2000-2005). Risk adjusted returns (using Jensen's alpha) indicate that average annual underperformance is around 1.52% in the 2000-2005 period for our sample and .88% over the whole sample period. Our results contrast with many previous studies (both Australian and international), which have not found statistically significant differences in the performance of ethical funds relative to market benchmarks and/or a matched sample of conventional funds.

Just as intelligent design is not a legitimate branch of biology in public educational institutions, nor should the philosophy of religion be a legitimate branch of philosophy. So argues leading atheist thinker and writer John Loftus in this forceful takedown of the very discipline in which he was trained. In his call for ending the philosophy of religion, he argues that as it is presently being practiced, the main reason the discipline exists is to serve the faith claims of Christianity. (...) Most of philosophy of religion has become little more than an effort to defend and rationalize preexisting Christian beliefs. If subjects such as biology, chemistry, physics, and geology are all taught without reference to faith-based supernatural forces as explanations, it should not be acceptable in this discipline either. While the book offers a fascinating study of the fallacies and flaws on which one whole field of study rests, it speaks to something much larger in the ongoing culture wars. By highlighting the stark differences between faith-based reasoning and evidence-based reasoning, Loftus presents vital arguments and lessons about the importance of critical thinking in all aspects of life and living. His conclusions and recommendations thus resonate far beyond the ivory towers and ivy-covered walls of academic institutions. (shrink)
