(1) Mazur & Booth do not explain precontest rise in testosterone. Anticipatory T rise may result from fantasized dominance scenarios. (2) Mazur & Booth conclude that females do not experience the dominance–T rise effect. The data are insufficient for this judgment. (3) Mazur & Booth misstate my position on T and sexuality. I offer an emendation and correction.

Constructive Neutral Evolution is an evolutionary mechanism that can explain much molecular inter-dependence and organismal complexity without assuming positive selection favoring such dependency or complexity, either directly or as a byproduct of adaptation. It differs from but complements other non-selective explanations for complexity, such as genetic drift and the Zero Force Evolutionary Law, by being ratchet-like in character. With CNE, purifying selection maintains dependencies or complexities that were neutrally evolved. Preliminary treatments use it to explain specific genetic and molecular structures (...) or processes, such as retained gene duplications, the spliceosome, and RNA editing. Here we aim to expand the scope of such explanation beyond the molecular level, integrating CNE with Multi-Level Selection theory, and arguing that several popular higher-level selection scenarios are in fact instances of CNE. Suitably contextualized, CNE occurs at any level in the biological hierarchy at which natural selection as normally construed occurs. As examples, we focus on modularity in protein–protein interaction networks or “interactomes,” the origin of eukaryotic cells and the evolution of co-dependence in microbial communities—a variant of the “Black Queen Hypothesis” which we call the “Gray Queen Hypothesis”.

Can there be a moral philosophy which combines Christianity and consequentialism? John Stuart Mill himself claimed that these positions were, at the least, not mutually exclusive, and quite possibly even congenial to one another; and some recent work by Christian philosophers in America has resurrected this claim. But there is a simple argument to show that consequentialism and orthodox Christianity are not so much as jointly assertible.

Constructive Neutral Evolution theory provides selectively neutral explanations of the origin and maintenance of biological complexity. This essay provides an analysis of CNE as an explanatory strategy defined by a tripartite set of conditions, and shows how this applies to cases of the evolution of complexity at higher-levels of the biological hierarchy. CNE was initially deployed to help explain a variety of complex molecular structures and processes, including spliceosomal splicing, trypansomal pan-editing, scrambled genes in ciliates, duplicate gene retention and fungal (...) ATP synthetase structure. CNE has also been generalized to apply to phenomena at the cellular level, including protein-protein interaction network modularity, obligate microbial symbioses, eukaryogenesis and microbial unculturability. This essay further extends CNE to cases of complexity at levels of organization higher than the molecular and cellular. These are multicellular phenotypic complexity, multicellular ecological complexity and, some cases of cultural complexity. (shrink)

Based on concepts of self-organization, we interpret apparent motion as the result of a so-called non-equilibrium phase transition of the perceptual system with the stimulus-onset asynchrony (SOA) acting as a control parameter. Accordingly, we predict a significantly increasing variance of the quality index of apparent motion close to critical SOAs. [Shepard].

I compare the two main readings of the argument against Protagorean relativism that 'Socrates' presents at Theaetetus 170-171, argue against both of them, and present a third alternative reading.

Protagoras believes that all beliefs are true. Since Protagoras' belief that all beliefs are true is itself a belief, it follows from Protagoras' belief that all beliefs are true that Protagoras' belief is true. But what about the belief that Protagoras' belief is false? Doesn't it follow, by parallel reasoning and not at all trivially, that if all beliefs are true and there is a belief that Protagoras' belief is false, then Protagoras' belief is false?

Developing a British perspective on the abortion debate, I take up some ideas from Patrick Lee’s fine paper, and pursue, in particular, the idea of individual humans as goods in themselves. I argue that this notion helps us to avoid the familiar mistake of making moral value impersonal. It also shows us the way out of consequentialism. Since the most philosophically viable notion of the person, the individual human, is (as Lee argues) a notion of an individual substance that is (...) there from conception, the move has a third effect, which is to rule out abortion.

Quentin Smith contends that modern science provides enough evidence ‘to justify the belief that the universe began to exist without being caused to do so.’ There was a time when such a claim would have been dismissed because it conflicts with a principle absolutely fundamental to all human thought, including science itself. As Thomas Reid expressed the matter: That neither existence, nor any mode of existence, can begin without an efficient cause is a principle that appears very early in the (...) mind of man; and it is so universal, and so firmly rooted in human nature, that the most determined scepticism cannot eradicate it.
