I only just found this video, (a lecture from 2008). The topic is very technical but I think Malcolm Jeeves makes a fantastic job of making the topic available to us as members of the general public.
To pique your interest, here is a quote
The accumulating evidence from neuropsychology makes it extremely difficult to maintain a view that there are two different substances interacting in the human person. All the emphasis rather is on the unity of the person, two aspects of which must be studied and taken seriously if a full account is to be given of the mystery of the human person.
Clearly we must discount the idea that ‘in-breathing’ should be equated with the acquisition of a ‘soul’. Joel Green comments on the word translated ‘soul’ in Gen. 2: 7 (“The Lord God formed a human being of the dust of the ground, breathed into his nostrils the breath of life, and the human being became a living soul”):
In fact, the same term (a living soul) is used only a few verses earlier with reference to ‘every beast of the earth’, ‘every bird of the air’ and ‘everything that creeps on the earth’ – that is, to everything in which there is life, demonstrating incontrovertibly that ‘soul’ is not, under this accounting, a unique characteristic of the human person? Genesis does not define humanity in essentialist terms but in relational – more specifically identifying the human person as Yahweh’s partner.
I was specially moved by Malcolm Jeeves words here :
Whatever therefore is to be said about the human cannot be confined to general statements about humanity apart from God. It cannot be said apart from the discovery that in Jesus Christ we see who we are and we also see God for us. And what he said about the human cannot be said as a general statement that assumes that what we see now is all there is to see. The answer to the question about who we are is finally eschatological, where tears are no longer part of the human reality, where joy is the order of eternity, and where our transience disappears in the disappearance of death. We cannot see that yet. But we do see Jesus. That will have to do. I think it is enough”. And speaking personally, for me it certainly is.
