OK, duendy, let's cut this problem into parts. Let's start with the first part. The spirit.

I think 'thing' is a good word, it implying something that has been descibed vaguely. I make no assumptions about a 'spirit', other than if it is supposedly associated with our bodies and minds, and somehow is part of our personality, it must be able to interact with our brain somehow.
me::that sounds to me like Cartesian dualism. Ie., te idea that 'mind' or 'spiri' has to 'make contact' with 'physical' brain. Descartes presumed 'it' did so via the pineal gland. He sa typically trying to understand all tis though his current mechanical understanding of te times, hence the words he used like 'pulleys' etc
Our brain being physical, somehow the 'spirit' must be able to affect the physical to express itself.
me::again, you are lookingat this throug a dualistic presuppposition which demnds that 'spirit' and Nature are seprate and 'ned' to interact through some means. why cant you accept that they were nve separated in the first place? Iti only indoctrination from patriarchal mythology, religiousbliefs, philosophy, and sciencism that this has ben diseminated!
and Kinda like a driver can hold onto a steering wheel to steer the car, if you will.
me::that is likemte idea that tere is a little-man in the brian running thing. i dont go wit that. it is much more complex than tat.
A professor of philosophy is a good source to look at. he's Christian de Quincey
http://www.deepspirit.com where he argues that the 'problem' of scinces 'mind/body' problem comes from a series of false avenues taken over te centuries regarding this conundrum......Asi just said, Rene Decartes attempted to try and explain it, but wa unknowingly caught up in his unconscious preconceptions, which were/are mechancial and extremely limited.........But ewven today te problem continiues hence te current 'hard problem' (David Chalmers)considering the 'problem' of qualia, subjective consciousness
so what is 'spirit'?
If a spirit can interact with a physical brain, some facet of it must be similar to a brain, and as brains use electrical currents, I'd expect to be able to detect that facet, or whichever way it interacts with the physical world.
me::de Quincey explains it thus: yo cannot use 'energy talk' when you are talking about consciousness. because consciousness cnnot BE measured. so to call it waves, or electrical charge, or any'ting' isenergy talk....checkout hisessay about this
Yet he is not being Idealistic. he is not saying that 'conciousness o spirit came first and 'matter' is less-than, or vicw versa which materialist scince states. rathe that matter-eenergy and consciousness are ALWAYS togther yt distinct, like the substance and shape of a tennis ball
If this isn't what you understand by spirit, please give your definition, so we have a common term to discuss.
