Philosophical tradition demands rational reflection as a condition for genuine moral acts. But the grounds for that requirement are untenable, and when the requirement is dropped morality comes into clearer view as a naturally developing phenomenon that is not confined to human beings and does not require higher-level rational reflective processes. Rational consideration of rules and duties can enhance and extend moral behavior, but rationality is not necessary for morality and (contrary to the Kantian tradition represented by Thomas Nagel) morality (...) cannot transcend its biological roots. Recognizing this helps forge a complementary rather than competitive relation between feminist care-based ethics and rationalistic duty-based ethics. (shrink)

Group selection is increasingly being viewed as an important force in human evolution. This paper examines the views of R.D. Alexander, one of the most influential thinkers about human behavior from an evolutionary perspective, on the subject of group selection. Alexander's general conception of evolution is based on the gene-centered approach of G.C. Williams, but he has also emphasized a potential role for group selection in the evolution of individual genomes and in human evolution. Alexander's views are internally inconsistent and (...) underestimate the importance of group selection. Specific themes that Alexander has developed in his account of human evolution are important but are best understood within the framework of multilevel selection theory. From this perspective, Alexander's views on moral systems are not the radical departure from conventional views that he claims, but remain radical in another way more compatible with conventional views.

Conventional wisdom generally seeks to support the notion that we cannot arrive at ethics by considerations of the state of the world. If we do this we are guilty of committing the ‘Naturalistic Fallacy’. This paper seeks to refute these contentions. I it I note that words are tools that humans use with the intention of promoting their survival. This ties into ethics, which are essentially a subset of the words used to promote human survival through their use in expressing (...) intentions of the way humans should behave. So ethics are a product of our evolution and, like words, they occupy the status of survival promoting tools. This paper argues that there is no category difference in the words that we use to describe the world or those used with the intention of promoting particular human behaviours—both are used with the intention of enhancing human survival.

Contrary to widely held assumptions, an evolutionary metaethics need not be non-cognitivist. I define evolutionary metaethics as the claim that certain phenotypic traits expressing certain genes are both necessary and sufficient for explanation of all other phenotypic traits we consider morally significant. A review of the influential cognitivist Immanuel Kants metaethics shows that much of his ethical theory is independent of the anti-naturalist metaphysics of transcendental idealism which itself is incompatible with evolutionary metaethics. By matching those independent aspects to an (...) evolutionary metaethics a cognitivist Kantian evolutionary metaethical theory is a possibility for researchers to consider. (shrink)

There is a rather striking video currently used in police training. A firearms officer is caught on video shooting an armed suspect. The officer then gives his account of what happened, and there is no suggestion that he is tying to fabricate evidence. He says that he shot the suspect once; his partner says that he fired two shots. On the video we see four shots being deliberately fired. Memory, it seems, is an unreliable witness in situations of stress.

Considerations from evolutionary biology lead Michael Ruse, among others, to a naturalistic turn in philosophy. I assess some of the pragmatic and skeptical conclusions concerning ethics, religion, and epistemology that Ruse draws from his evolutionary naturalism. Finally, I argue that there is an essential tension between science and religion which forecloses the possibility of an ultimate reconciliation between the two as they are now understood.
