i disagree. what does it mean to be immaterial. is consciousness material? consciousness has interaction with the brain via chemical and biological processes but is it material in the sense that boris speaks of?
Consciousness does NOT have interaction with the brain. It IS the SUM OF INTERACTIONS of the brain with itself via the vast neural network.
It does not interact WITH the brain.
It is purely an internally driven process - that has physical inputs and physical outputs. Without input there is no internal interaction and no outputs - thus no consciousness (sum of zeros is zero).
Also see Boris' "Argument from Equivalence".

as i said above if you looked for a defintion of the brain and you found the definition only stated "the brain is physical" would that suffice as a definition? i should hope not. would you then build a reasonable argument around this definition?
Obviously the definition of "brain" and "soul" are more complex than whether or not they are matter or immaterial. That is not in dispute.
The whole of Boris' argument stems from the widely accepted understanding of the "soul" as being, among a plethora of other things, immaterial. The plethora of other things are not being questioned by Boris - he concentrates entirely on the "immaterial" nature of the soul.

besides which, how does boris know the soul is immaterial like i said it could be a very nimble form of matter which is cunning enough to out wit our soul detecting machines.
Boris doesn't know what the soul is made of.
His argument is one of countering the claim that the IMMATERIAL soul exists AND INTERACTS WITH the material body.
ellion said:
so! what does it consist of? this is why the defintion given does not suffice. we need more infromation, what is it if not material? is it a principle? an idea? a perceived individuality? a relationship to a principality? a collection of personality charecteristics? what? what is it?
The Soul is either MATERIAL or IMMATERIAL.
If it is IMMATERIAL - then Boris' post applies.
If it is MATERIAL then please provide evidence of it.
ellion said:
right, so he has defined the soul in such a way that it is easily refuted by his argument, and you are willing to accept this without question, are you?
Boris is merely starting with an assumption of the soul (that it is material) and showing how it either doesn't exist or can not interract meaningfully with the physical / material.
If you disagree with the assumption that the soul is immaterial then naturally the rest of his arguments are not applicable to your definition of "soul".
If that is the case, then your definition must include the fact that the soul is "material" (as a soul can not be both "not material" and not "immaterial" - i.e. it is either material or it is immaterial).
If you agree that the soul is immaterial then Boris' arguments apply.
Or do you think the soul is material?
