Kepler said:
A case for an immortal soul can be posited starting with Genesis chapter one. If an invisible God fashions man and woman in the image of himself (Gen 1:27), then a definition of what the soul is would depend on whether we define God as a universal wind or breath or something even more fundamental.
That assumption is highly questionable, for ohhh so many reasons.
The reason for mentioning man being "made in the God's image" is actually the opposite as it suggests: YHWH is written in a manner to allow mortals to think of YHWH with man-like (anthropomorphic) qualities. At the time, the co-existent dieties were often inanimate (Sun god Ra), or animals; this was unlike the Greek pantheon, which also were God's made in man's image.
YHWH being man-like (mirror image) allows Genesis to have Him walking thru the Garden, hearing, seeing, looking, i.e. possessing similar personality traits and emotions as a man. In early Genesis, YHWH is depicted with humanlike foibles and short-comings, which become increasingly inconsistent as the OT unfolds; YHWH assumes those famous legendary properties (omniscience, omnipotence, immutable, etc), unfortunately breaking continuity with prior depictions (eg God shows regret twice in the Flood: that's not consistent with being omniscient).
Other reason, of course, is that God supposedly isn't confined to mortal form: he's supposedly purely existant, being in spirit form. Hence, all comparisons are off....
Oh, this:
He replied, "Truly I tell you, today you will be with me in Paradise."
Ahhh, the problems with recording God's message in a language without punctuation marks!
That scripture is famous for the ongoing debate about where the comma belongs, since it's anyone's guess.... Is it what you wrote above, or this:
He replied, "Truly I tell you today, you will be with me in Paradise."
Note how the meaning changed, simply by a translator's arbitrary decision to move the comma?
If it is as simple as residency in a brain, then perhaps "I" could be easily transferred to the computer - if not this year then maybe next.
Congratulations! You know something that so-called "Divinely-Inspired" ancient Hebrews and Early Christians didn't know: people think with their brain, not their heart.
Ancient Hebrews actually believed the organs of cognition in men were found in the TORSO, NOT the head. So whenever YWHW is quoted referring to "evil thoughts in the hearts of men", that is no figure of speech: that's exactly what ancient men believed in 500 BC (the role of the brain wasn't elucidated and became common knowledge until 100's of years AFTER the OT was complete. In fact, even Jesus referred to thoughts in men's hearts. The Hebrew and Greek words for both the heart (leber/cardia) and mind are different, and the Bible reflects the ignorance of ancients on the physiological roles of internal organs..
In fact, ancient Hebrews believed the head contained the seat of the generative reproductive life-force (spirit; this is differentiated from the loosely-related nephesh, commonly referred to as the soul), which served as the site of one's drive (Greeks/Romans referred to this as one's 'genius'; note the common prefix). However, all cognition and thinking was done in organs of the torso (heart, lungs, kidneys, etc).
