Hi Jessica,
Welcome to BioLogos. I understand struggling with anxiety. Try to keep in mind, though, that ALL concepts about God, the Soul, consciousness are human concepts. Don’t regard any human explanation or conception of anything as fact. It isn’t, it’s just people’s thoughts and ALL people’s thoughts are limited and, thus, missing something. Only God’s thoughts are not limited.
But there are some unequivocal things we can say about the soul.
One, it is not material and is not dependent on physical form. This is the case in the Bible, but also in many other cultures that have a concept of the soul, particularly those of India.
Two, it is eternal, neither being born nor dying, although—according to Jesus—being destroyable by God (and only by God).
Three, because of the first two, it is unknowable by us, at least while we are in this world, because in this world, we can only know what we can detect, which is limited to material things.
Whatever the soul actually is, we cannot know. Our cells are constantly dying and being replaced. We know this for a fact. The body you inhabit now is not actually the same body you inhabited a year ago. None of the cells of your previous body are in your current body. Yet, this change happened without anyone’s awareness. We only know it happened because we’ve studied cells and learned how they exist.
Yet, even this replacement of your body has been going on for as long as you’ve been alive, you body has been constant and continuous through all that time. That’s because it isn’t particular cells that make your body what it is, but rather the patterns of their organization and activities. Imagine if you made a lego figure and then replaced one of the white rectangular pieces with an identical rectangular piece. It would still be the same figure, right?
That’s how it is with our bodies, and I can’t say that there isn’t some equivalent thing happening with our souls—something along the lines of what Strawson claims. I believe I can say, though, that if there is, this is as irrelevant to the eternal continuity of our souls as it is to the continuity of our bodies.
I’m highly skeptical of Strawson’s claim, though, because in the case of the body, as i said above, the constant replacement of cells is NOT a constant replacement of the body. The body is not changed by this. It seems to me that if there is some equivalent thing going on with our souls, that our souls also would not be changed by this. They would remain eternal, because whatever it is about them that is changing, is NOT what makes the soul what it is and eternal is what it is.
I hope you find this helpful.
