Who or what is the entity known as ‘I’? The whole composite of mind and body? Or just the persistent voice in ‘my’ head that tries to deal with the rest? And how do ‘my’ deep-sleep dreams fit into the definition you prefer? Thinkers down the ages have wrestled with the topic and supernaturalists have formulated conflicting explanations, leading to revolution and war. And now some new science will fuel the flames of the debate. There seems to be brain activity after ‘death’ as defined by accepted medical practice.
Does this persistent brain activity have any ‘purpose’? Is the owner ‘conscious’ of it? That is, what is it for, if anything? Or is it like the decapitated chicken that keeps on running? Or a turbine spinning after shut-down?
