What Dualism for Christ sake ? "Matter" and "Spirit" is just information !
Even if it where true that there are these two "substances", that which makes them different is just the adding or the lacking of more dimensions or levels on how information gets assembled...but so it happens that one of them gets to be called "material" because it implies the presence of touch, that is, a sensorial coordinate that it can affect...one more in the line of "programming" in it, which technically differentiates it from "Spirit"...the very difference from which we project the solving of all our little pitiful species frustrations associated with our "fleshfull" circumstance... in the 21 century the all thing is just nonsense... arghhhhhh !!!
But if to reclaim the "Salvation" of the terms how should we Philosophically think on it ?
Just what "could be" the "SPIRIT" then ?
1 - The dynamic...the manifestation...the Phenomena...the "Breathing" of the thing...(from the Latin "SPIRARE")
And "Matter" ? (in contrast)
2 - That which is Final !...That which Change cannot change...the Being beyond History...the simultaneity of all times and all thing in the unity of "Existence" !...(hell, its not even about our daily concept of matter)
