In the previous post, I proposed that
1. In addition to all the carbon, hydrogen, oxygen, nitrogen and whatnot that we know we all have, we also possess zerairds, and that
2. These zerairds are the source of free will and consciousness, collectively sentience.
These differentiate us from stones and corpses. I believe, also from plants and microorganisms. Possibly, from insects. Not, however, from dogs and doves, cows and crows. Different faiths see these differently: Christianity appears to believe that only humans possess zerairds, whereas the austerest Jains see zerairds in stones too.
Ah, am I agreeing too much with religions? ... No!
All the science we know tells us that matter (matter-energy, after relativity) - that is to say the carbon, hydrogen and whatnot - cannot be created or destroyed. It does not recognize zerairds, hence no comments.
Common religions, on the other hand, hold the body to be perishable, and says souls live forever. Clearly, it is wrong on at least one count. The second law of thermodynamics notwithstanding, we should be able to reverse "material death" - at the cost of a lot of entropy generated elsewhere.
I believe common religion to be wrong on BOTH counts. I believe that our zerairds are created upon our birth, and destroyed upon our death. The assymmetry does appeal to me! Besides, whilst it is possible that the zeraird enters from elsewhere into a baby upon birth, and leaves a person upon their death, we have no evidence of it.
More on this later, but I also find it comforting to believe that one day my zeraird will be completely finished.
