I am not committed to the view that the brain is the driver of culture, any more than I am to the view that culture is the driver of brain development. They will inevitably mould each other. But one of the constraints on how we see the world has to be the balancing of the options given to us by the two cerebral hemispheres. These constitute relatively stable differences over the length of human history. Cultural shifts can exploit such options: but hemisphere differences would still constrain the options available to the human mind.
