Vallortigara & Rogers (V&R) assume that the alignment of escape responses in gregarious species is the central evolutionary organizer of a wide range of cerebral asymmetries. Although it is indeed likely that the benefits of a population asymmetry in social species outweigh its costs, it is hard to see (a) why the population should not oscillate between two subgroups with mirror-image asymmetries, (b) why solitary animals should keep their inherited population asymmetry despite a resulting fitness reduction, and (c) and why so many vertebrate species have comparable cerebral asymmetries.

The cerebral distinctness of the linguistic and mathematical faculties does not entail their functional independence. Approaches to language that posit a common foundation for the two make claims about design features, not location, and are thus not affected by the finding that one ability can be spared by a neurological accident that compromises the other.

Merker's approach allows the formulation of an evolutionary view of consciousness that abandons a dependence on structural homology – in this case, the presence of a cerebral cortex – in favor of functional concordance. In contrast to Merker, though, I maintain that the emergence of complex, dynamic interactions, such as those which occur between thalamus and cortex, was central to the appearance of consciousness.

The problem of inferiority, of subjectivity, of conscience, is not only a metaphysical or psychological problem; it is susceptible to objective scientific study at the neurophysiological level. This study must not stop, however, at an analysis of cerebral function but must also recognize that conscience results from the self-being of the individual at himself in certain structures of his brain and that a cerebral process is or is not conscious according to whether or not it is integrated into the structure of the whole. This is best developed in man by virtue of the cerebral complexity which makes possible the verbalization of one self. The spiritual always appears as a functional, nonlocalizable aspect of the whole of the aggregate individual.

Whether or not a public relations code of ethics should be enforced, among others, has become one of the most widely controversial topics, especially after the Hill and Knowlton case in 1992. I take the position that ethical codes should be enforced and address this issue from eight aspects: (a) Is a code of ethics an absolute prerequisite of professionalism? (b) Should problems of rhetoric per se in a code of ethics become a rationale against code enforcement? (c) Is a code of ethics of any significance? (d) Is the ethical code is enforceable, (e) Would the licensure system interfere with the freedom of expression of the practitioners? (f) Do PR practitioners choose to be ethical (if they do) because they have to be or because they want to be? (g) Would the public interest be virtually assured as a result of a public relations? and (h) Can education in ethics overcome the ethical problems in public relations?

Since Richard Dawkins' The Extended Phenotype got me to thinking about copying units in the mid-1980s, I have been trying to define a cerebral code (the spatiotemporal firing pattern that represents a word, image, metaphor, or even a sentence) by searching for what can be successfully replicated in the brain's neural circuitry, a minimum replicable unit. I indeed found such circuitry (it implies that the firing pattern within several hundred minicolumns of neocortex, contained in a 0.5 mm hexagon, is such a copying unit). But to explore creativity in higher intellectual function, I wanted to see if the resulting copies could compete in a Darwinian manner, the process shaping up quality as it goes. And that forced me to try and boil down a lot of evolutionary biology, attempting to abstract the features that were essential (for what I came to call "the full-fledged Darwinian process") from those that merely contributed to speed or stability. This isn't the place to describe the neural outcome -- it's in The Cerebral Code and, more briefly, in the seventh chapter of my other 1996 book, How Brains Think -- but this does seem an appropriate place to review what I started calling "The Six Essentials." They seem applicable to a wide range of problems within memetics9 as the field attempts to cope with evolutionary models of information transmission. For a more..
