This morning a strange thing happened: Lewis and I found ourselves in the car alone. No interruptions from the children, and Lewis about to teach on–you guessed it–Aristotle on the soul. I dug into the topic this morning in the car with an unusual sense of having a stake in the question. The question began as 'how is the soul the form of the body, for Aristotle?' That's quite a difficult question to answer, as it happens, and I expect more conversation will take place the next time Lewis and I have a l chance to take it up. If anyone happens to have an answer to hand, I would love to hear it.
Fear not: I am not going to rehearse here Aristotle's doctrine of the soul. My hunch is that it loses something in the process of being summarised. Besides, it is full of paradox and warrants a sort of attention I am not able to give it. But I should, and I will, because what I could recognise immediately in Aristotle's account of the soul is the way it shows up in the Questions on the Soul of St Thomas Aquinas. His account of the soul is, not surprisingly, full of paradox and has been the subject of at least one paper I have read recently, and two that I have given at conferences. Surely there was plenty of conversation about the topic last June at a conference on the soul in Oxford (which I was unable to attend, sadly).
The question of the soul interests me because I am very anxious to retain soul language in Christian discourse. No, I don't think it is much threatened in mainstream Christianity, but I do think it is widely taken for granted. That means we tend not to teach about the nature of the soul or its function in our Christian life. I think (not without some background, I promise) that 'soul' names an aspect of human life that is inseparable from body and mind, but not coterminous with either. It's important, because sickness in body and mind is not the same as sickness of the soul; weakness in mind or body is not the same as weakness of the soul.
It's important because the question 'In what sense do [people with profound cognitive impairment] have a soul?' (which Frances Young raises in Face to Face) needs an answer that is careful and deeply grounded theologically. I would argue strenuously that people with severe developmental and cognitive disabilities have souls, regardless of whether their engagement with the world around them has grown beyond the level of an infant. The soul is not the same as the mind, and not the same as the body. We are too used to thinking about our relationships with one another and with God as somehow dependent on our own agency. But it is not so, not necessarily so. An infant does not yet exercise the kind of agency that sustains the relationship into which he or she has been born; the relationship exists, to begin with, because a parent does the work of relating to and caring for the infant. Of course our relationships with one another can be mutually intellectually stimulating and emotionally satisfying, and such friendships are to be cherished. But if our relationships depended on others when we were tiny infants, so much more does our relationship with God depend on God.
I don't pretend to know exactly what the soul is. I cannot tell you in what sense it is the 'form of the body' for Aristotle. But I think that in saying that we have souls–that we are embodied souls, or ensouled bodies–we are affirming that there is a mysterious dimension to human existence. We are saying that God relates to each and every one of us as a parent to a tiny child, in the sense that there is a tremendous inequality between the parent's ability to understand, to care for, to bear with, and to meet the needs of the infant child, and the infant's ability to do anything for the parent. The idea of a 'soul' can remind us that we receive our very life from God, regardless of the capacities of our minds and bodies. The soul's capacity for God is not diminished by mental or physical incapacity, but by sin.
But sin is another topic entirely, best left for another day.
