In one of his letters Saint Theophan the Recluse says, '… ***When God created man, He first formed a body from dust. What was that body? An earthware greyhen or a living body? It was a living body; it was an animal in the form of man with the animal soul. Then God breathed His spirit into him and the animal became man - an angel in the form of man. As it was at that time, so, in the same way, also now men come into being. The souls are born from the parents or are put in through the natural birth, but the spirit is breathed in by God Who is everywhere… When you say man is an animal, do you only mean the meat or the whole animal life? Of course, the whole animal life together with the soul of animal. But adding [the word] ‘rational’ to this [that is, ‘rational animal’], what does this mean? This means that though man, on the one hand, is the same as the animal with the animal soul, on the other hand, he is incomparably higher than animals, as he has ration (/intellect) which perfectly corresponds to to the word ‘spirit’. To say ‘rational animal’ is the same as to say ‘spiritual (lit. spiritualized) animal’. ***
Then he speaks of the ‘organic life’ which exists in different classes of beings- plants, animals and men, but is the same in all of them. The only difference is our mind which he calls ‘spirit’.
The human rational soul corresponds to the ‘spirit’ (pneuma) in I Thessalonians 5:23, the sensible part corresponds to the ‘soul’ (psyche), the vegetative part to the ‘body’ (soma).
So pneuma has a supernatural origin, whereas the origin of psyche and soma is purely natural.
The stuff that’s inside our bodies like our bones, organs, muscles etc. are made of various molecules and atoms. Humans and all other creatures are mostly made of water, so we are mostly made of atoms 13 billion years old.
Could our “sensitive soul” - the internal senses of imagination, common sense, estimation, and the memorative which represent the ability to store, use, and process that obtained knowledge and information - also come from previous life-forms? Our sensitive soul is purely natural.
I don’t think there is science to back up the existence of “mental energy” that is transmuted and passed on like human atoms and other forms of energy, but if there was, then this is the only way I could ever conceive of Catholics accepting something akin to this and it would not be possible to do so for the rational soul.
I am considering this because while reincarnation is clearly impossible - the rational and sensitive souls are both transient, so there is no “soul” that can be passed between bodies - the bodies conception of “rebirth” is different, this thread has shown as much.
The Buddhist teaching interests and intrigues me a lot more actually.
Catholicism does not accept an immortal “life-force” just like Buddhism, that exists in all creatures unchanging. For us vegetative and sensitive souls are transient and material.
Where we differ is the “spirit” breathed by God into man, this spiritual, supernatural quality to man’s soul which differentiates him from other life-forms and ensures that his rational soul does not “return to the earth”.
My spirit, my spiritual soul came from God and will return to him. My vegetative and sensitive soul was produced by nature and is transient and empty like all natural things.
As the Bible says:
“…All that is of earth returns to earth, and what is from above returns above, all streams shall return to the sea…”
- Sirach 40:11
“…I said in my heart with regard to human beings that God is testing them to show that they are but animals. For the fate of humans and the fate of animals is the same; as one dies, so dies the other. They all have the same breath/spirit [animal soul], and humans have no advantage over the animals; for all is impermanent. All go to one place; all are from the dust, and all turn to dust again. Who knows whether the human spirit goes upward and the spirit of animals goes downward to the earth?..”
So the Bible agrees with Buddhism that the “soul” is not immortal but dies in both humans and animals.
Who knows - maybe there is a cycle on earth whereby the mental phenomena of transient sensitive souls “returns to earth” in an endless cycle of transmuting between different beings. Perhaps mine will too!
Maybe Aquinas was slightly off in saying that the vegetative and sensitive souls “die”. Maybe their information does transmute and get passed around. We do know that nature has a way of using itself up and not wasting anything. So perhaps there is mental energy which is “reborn” in other beings.
Nonetheless man’s rational soul has a spiritual character which is not natural but “supernatural” for Christians and so “returns above” as the Book of Sirach explains. It is not part of this cycle (if it exists - and I’m open to it).
I don’t see why its not at least plausible.
