@Sea Breeze: information (energy or the reduction of entropy) does have mass, that’s the whole idea behind E=MC2
The information on a hard drive or in a brain however is just storage, both the existence or lack of useful/structured information is information in itself (eg. If you have a (partially) blank drive, you can infer knowledge about the use of the drive for example).
Things like logical constructs and language are related to the physical, the soul as you describe is metaphysical and very much a Christian idea, based on Plato’s teachings, most other religions do not share the same ideas. Other religions (eg. Judaism) does not share the modern idea of the Christian soul, the Hebrew Scriptures do not support the translation of the single word “soul”, which is an invention of Medieval Christianity, rather the original text has Neshamah (life itself, the human animating force) Nefesh (living person related to its material needs) and Ruach (a divine animating force) but nowhere do these seem to indicate a separate being, although life force in later scriptures can return to God, it does not seem to imply a personality or connectedness to the individual or body (more a ‘conservation of energy’ type deal).
