Spirits and souls (not soles...)
The brain, so science has shown, is a biological entity. The mind, however, which by all accounts is a function of the brain, is simply a collection of electromagnetic interactions with synergistic functions - i.e., the whole is greater than the sum of the parts. It is reasonable to assume that there is a soul, as well - however, from whence would the soul derive, and what form would it take? These questions were the exclusive realm of theologists and priests until very recently, but superstring theory and, particularly, hyperspatial studies have opened up new avenues of exploration and (in far greater quantity) speculation. The theory goes that the mind, which retains it's general format for life (barring major accidents), will gradually imprint it's pattern on space-time's higher dimensions, which are "curled" up very small and tight, retaining it's form in hyperspace after death of the biological housing. As a mind is the ulitmate anti-thesis of entropy, however, I don't think such a form would last long without it's biological anchor to sustain it and would soon decay into it's constituent energy. Just my thoughts. (I'm studying superstring theory at the moment- lots of good books on it) 🙂
