Michael Gazzaniga on the Science of Mind Constraining Matter

Michael Gazzaniga. Can neuroscience explain it? You know – consciousness, being, the number 42. And if everything you thought you were transpired to be nothing more than an easily deceived heap of neurons, would that trouble “you”?

During October 2009, Michael Gazzaniga gave a fascinating series of Gifford lectures exploring how our brains process the information that gives us our sense of “I”. Gazzaniga drew extensively from neuropsychological studies of people with “split brains” (explained later) to develop the notion of a single “interpreter” within the brain – a part of the brain that analyses all the data available for meaning.

Michael Gazzaniga then attempted to rationalise the interpreter, concluding that our focus should be on the interactions of people, not the brain itself. This logic was then expanded to wider society – social structure, interaction, and law. Those later thoughts raised many more questions than were answered.

This article attempts to summarise the key themes in a non-technical manner, with a few naive attempts to interrogate the theories developed. This is my interpretation of 6 hours of lectures. Interpretation, because I tend to recreate Gazzaniga’s conclusions by re-analysing the information presented. With a complex topic such as this, it is likely that some of my interpretations will differ from his. Sections titled “Interlude” are entirely my analysis. Read More
