Since I’m doing a sermon series on image and identity, I picked up Love Thy Body by Nancy Pearcey. I’ve mentioned it here several times in the past month or two. I also recently picked up Body and Soul: Human Nature and the Crisis in Ethics by J. P. Moreland and Scott Rae. Body and Soul is a biblical and philosophical study of the human body and the human soul: what they are and how they relate. It’s a rather difficult read, to be honest, since it is a philosophical look at these topics. I’m learning some new things such as metaphysical distinctions relevant to anthropology, degreed and nondegreed property, mereology, and so on.
The main thesis of the book is that, in the authors’ view, human persons are not property-things, but substances. They back up their thesis with Scripture and with logical arguments from philosophy. The last three chapters are application chapters where the authors discuss beginning of life ethics and end of life ethics based on their biblical and philosophical view that humans are substances, not property-things.
One part I appreciated was where they discussed science’s input on human persons:
In our view, when it comes to addressing the nature of human persons, science is largely incompetent either to frame the correct questions or to provide answers. The hard sciences are at their best when they describe how physical systems work, but they are largely incompetent when settling questions about the nature of consciousness, intentionality, personal identity and agency, and related matters. Recently, philosopher and scientific naturalist John Searle have argued that 15 years of focused on philosophy of mind, artificial intelligence and cognitive psychological models of consciousness have been a waste of time in a number of ways…
… We do not agree with everything Searle says here, but he is correct in claiming that various disciplines studying the nature of human persons have been mired in chaos and confusion for at least a half a century. In our view, the reason for this chaos has been the assumption that science is the best way to approach the relevant questions.
The authors go on to give some assertions that are very difficult, if not impossible, for hard sciences to explain (e.g. mental states, the human soul, thoughts, etc.). I agree with Moreland and Rae in that science can do much to help our understanding of humans, but science has its limits. Thankfully we have God’s Word, which not only tells us about him, it also tells us about ourselves, humans, made in the image of God, body and soul, male and female. And Scripture gives us a teleological outlook: the chief end of man is to glorify and enjoy God forever!
The above quote is found on pages 41-42 of Moreland and Rae, Body & Soul: Human Nature & the Crisis in Ethics.
