I will return here to the nature of the 5 th band of the overall spectrum of development (that I outlined again briefly yesterday). Actually this is where I would make another slight modification with respect to the position I outlined some five years ago!. I referred then to this as representing the first of the radial bands of development, where linear (rational) and circular (intuitive) modes of understanding are comprehensively integrated in a mature manner. However I would now consider on reflection that this band should be referred to more accurately as pre-radial. Indeed there is an interesting - and not entirely accidental - connection here with another finding that I outlined yesterday with respect to cyclic primes. And as this whole episode illustrates the nature of holistic - as opposed to analytic - behaviour well, I will relate it here. Many years ago when I was developing my holistic approach to number types, I began to realise that there were stro...
