As I have mentioned earlier, emotional states appear to transfer between the hemispheres subcortically, and this transfer is not affected by severing… - Michael S. Gazzaniga

Margaret Mead once remarked that she thought all Caltech men thought women had a staple in their belly button because the only time they viewed a women naked was in the foldout of Playboy.

Why has DNA had a monopoly on molecular symbolism over the past few hundreds of millions of years? In its physical manifestation, DNA is extremely structurally stable, unlike RNA. This has helped DNA remain the symbolic structure of choice throughout evolution. However, while the DNA in our cells and the cells of other living organisms is now very stable, the structure of DNA did not start out that way at the very origins of life. Random shuffling and re-sorting of molecules, through the irreversible and probabilistic process of natural selection, generated molecules resembling nucleotide bases. Through subsequent shuffling, successful DNA components and sequences survived and replicated.

The tension felt in the modern world between those who look at the confluence of neuroscientific data, historical data, and other information illuminating our past and those who simply accept received wisdom as their guide in life is real and profound. Yet it may not be as divisive as one would think. It appears that all of us share the same moral networks and systems, and we all respond in similar ways to similar issues. The only thing different, then, is not our behavior but our theories about why we respond the way we do. It seems to me that understanding that our theories are the source of all our conflicts would go a long way in helping people with different belief systems to get along.
