The Two-Minds View: Thomas Morris and the Dual-Consciousness Model

Two Streams of Thought in One Person?

Introduction: A Serious Proposal Worth Engaging

Of all the modern attempts to make sense of how one Person can be both fully God and fully human, few have been as influential as Thomas V. Morris's "two-minds" view. In his 1986 book The Logic of God Incarnate, Morris revived what he called an "ancient view" of the Incarnation, arguing that Christ has two distinct minds — one divine and one human — operating at the same time within the one Person of the Son.¹ Morris's proposal has shaped a generation of evangelical thinking on Christology, with thinkers like Wayne Grudem and John Feinberg following in its wake.²

I want to begin by saying something I think is important: Morris is on our side in the most fundamental ways. He defends the full deity and full humanity of Christ. He rejects kenoticism. He believes Jesus has a real human mind with real human limits. And he is taking seriously the very thing physicalist Christologies cannot — namely, that Christ has a genuine inner life that is not reducible to brain activity. So this chapter is not a takedown. It is a careful conversation between friends who agree on more than they disagree on.

That said, I think Morris's model — for all its strengths — runs into some problems that the kryptic model defended by Andrew Loke (which I will set out fully in the next chapter) better avoids. The biggest problem is that two simultaneous streams of consciousness look uncomfortably like two subjects. And two subjects, in classical Christology, look uncomfortably like Nestorianism. In what follows, I will lay out Morris's view fairly, identify what it gets right, and then explain why I believe a one-consciousness model is preferable. Along the way I will show why both Morris's model and the kryptic model presuppose that Christ has a genuine human soul — and why neither can survive the move to physicalism.

What Morris Proposes

The heart of Morris's view is what he calls the "asymmetric accessing relation" between Christ's two minds.³ On Morris's account, the incarnate Logos has two distinct minds with two distinct streams of consciousness:

(1) The eternal divine mind of the Son, which encompasses the full scope of omniscience and is consciously aware of everything. (2) A human mind that came into existence at the conception of Jesus, grew and developed with him, and was not consciously aware of everything.⁴

The divine mind, Morris says, "contained, but was not contained by," the earthly mind. The divine mind had full and direct access to everything in the human mind, but the human mind only had access to the divine mind on those occasions when the divine mind allowed it.⁵ Joshua Farris helpfully summarizes the idea using Morris's own words:

In the case of God Incarnate we must recognize something like two distinct minds or systems of mentality. There is first what we can call the eternal mind of God the Son, with its distinctively divine consciousness... encompassing the full scope of omniscience, empowered by the resources of omnipotence, and present in power and knowledge throughout the entirety of the creation. And, in addition to this divine mind, there is a distinctly earthly mind... that came into existence and developed with the conception, human birth and growth of Christ's earthly form of existence.⁶

Picture it like this: imagine a powerful floodlight that illuminates an entire stadium. Inside that floodlight, there is also a smaller, focused spotlight that illuminates only a particular section of the field. The floodlight (the divine mind) sees everything the spotlight sees, plus a great deal more. The spotlight (the human mind) sees only what falls within its narrower beam, and it knows about the floodlight only when the floodlight chooses to share its broader view. This is one way to picture the asymmetric access Morris describes.

Morris offers four kinds of analogy to make the model intuitive: two computer programs where one contains but is not contained by the other; the dream phenomenon, where the dreamer is both a character inside the dream and a sleeper aware that it is "just a dream"; the relationship between the conscious and the subconscious in modern psychology; and unusual cases like brain-hemisphere commissurotomy, multiple personality, and hypnosis.⁷ Morris does not claim these are perfect parallels — they are illustrations meant to show that the idea of one person with two streams of consciousness is at least conceivable.

What Morris Gets Right

Before raising any concerns, I want to be clear about what Morris's model contributes. Each of these is a genuine strength.

First, it preserves full deity. Unlike kenotic Christology (which I rejected in Chapter 15), the two-minds view does not require the Son to surrender omniscience, omnipotence, or omnipresence in order to become incarnate. The divine mind remains divine, with all the divine attributes intact. This is non-negotiable for orthodox Christology, and Morris gets it right.

Second, it preserves genuine humanity. The human mind of Jesus, on Morris's view, is a real mind with real limits. Jesus genuinely did not know the day or hour (Mark 13:32) at the human conscious level. He genuinely grew in wisdom (Luke 2:52). His temptations were real because the human mind doing the resisting was a real human mind, not a divine mind playing dress-up. This is the great Achilles' heel of Apollinarianism (which we'll examine more closely in Chapter 12), and Morris steers well clear of it.

Third, it avoids the logical problems of kenoticism. If divine attributes are essential to being God, then a being who lacks omniscience is not God. Kenoticism cannot escape this. But Morris does not need to surrender any divine attribute. The omniscience is still there in the divine mind — it just isn't flooding the human mind. This is a major advantage.

Fourth, it provides a clear model for the apparent contradictions in Scripture. How can Jesus be both omniscient and limited in knowledge? On Morris's view, He is omniscient in the divine mind and limited in the human mind. Both are true, in their respective spheres. The two-minds view dissolves the apparent contradiction by locating each predicate in the appropriate cognitive domain.

Timothy Pawl, in his rigorous defense of Conciliar Christology, treats Morris's view sympathetically and offers careful philosophical resources for defending it against the charge of Nestorianism. Pawl distinguishes between the metaphysical subject of characteristics (the supposit, or person) and the psychological centers of self-consciousness (the natures or faculties). On this distinction, two centers of consciousness need not imply two persons.⁸ This is a serious move, and the two-minds proponent has options for responding to objections.

Where I Part Ways: Two Streams or One?

So if Morris gets so much right, where exactly is the disagreement? It comes down to one fundamental question: How many simultaneous streams of conscious experience does Jesus have?

Morris's answer: two. There is a divine consciousness aware of all things, and a distinct human consciousness aware of only a limited range of things, both running in parallel within the one Person of the Son.

Loke's answer (which I will defend in Chapter 17): one. There is a single stream of conscious experience — a genuinely human one — with the divine attributes (omniscience, omnipotence, and so on) located at a "preconscious" level, available when the Father wills it, but not running as a parallel second stream of awareness.⁹

This sounds like a small difference. It is not. It has large consequences.

The Two-Subjects Worry

Here is the heart of the problem, as Loke presents it. If Christ has two distinct streams of consciousness, then He has two faculties of "I-thoughts" — two centers of self-awareness, two different "I-statements" running at the same time.¹⁰ Imagine the implications for Mark 13:32, where Jesus says no one knows the day or hour, "not even the Son." On the two-minds view:

The Logos in his human consciousness would be aware of himself being consciously unaware of the day of his coming. At the same time, the Logos in his divine consciousness would be aware of himself being consciously aware of the day of his coming. So the Logos would simultaneously be aware of himself being aware of the day, and aware of himself being unaware of the day.¹¹

Loke argues that "myself being consciously aware" and "myself being consciously unaware" are contradictory states, and that no single self can hold contradictory self-conscious states at once. To say there are two contradictory self-consciousnesses is to say there are two selves — and selves, in the relevant sense, are persons.¹² But Christ is one Person, not two. Therefore the two-minds view, taken to its logical end, dissolves into Nestorianism — the heresy that Christ is two persons rather than one.

There is a related worry. If the human mind and divine mind are both genuine streams of consciousness, then in principle they could speak to each other. The human Jesus could say "Thou" to the divine Logos, and the divine Logos could say "Thou" to the human Jesus. They could enter into an "I–Thou" relationship. But an "I–Thou" relationship implies two persons standing across from each other.¹³ And here the Gospels tell against the two-minds view: there is no record of Jesus' human consciousness ever addressing the divine Logos as a separate "Thou." Jesus addresses the Father. He never addresses His own divine nature.

Pawl pushes back on this argument. He distinguishes between the "I" of psychological experience and the "I" as the metaphysical subject of characteristics, drawing on a similar move by Richard Cross.¹⁴ On Pawl's reading, the two consciousnesses can address each other as faculties of one and the same supposit (the Person of the Son), without that addressing constituting two persons. This is a thoughtful response, and I won't pretend it can be dismissed easily.

But here is my honest reaction: the response feels strained. In ordinary experience, two centers of self-consciousness that can stand in an I–Thou relationship are precisely what we mean by two persons. The argument that they aren't requires us to redefine "person" in a fairly technical way. That isn't necessarily wrong — Christology has always required some technical distinctions — but the simpler model is the one that doesn't require the redefinition. Loke's one-consciousness model gives us one Person with one conscious experience straightforwardly, with no I–Thou worry to begin with.

Other Difficulties: The Spotlight Problem and Theopaschism

Beyond the two-subjects worry, two further problems deserve mention.

The first is what I'll call the spotlight problem. Morris's analogy is that the human mind is a "proper part" of the divine mind — the spotlight inside the floodlight. But this seems to make Christ's human nature a subdivision of His divine nature, rather than a genuinely distinct nature standing alongside it. Chalcedon insists the two natures are united "without confusion" and "without change."¹⁵ If the human mind is literally contained inside the divine mind as one of its parts, the picture starts looking more like a single mind with a sub-mind — a kind of nested mental hierarchy — than two genuinely distinct natures meeting in one Person. The concrete-nature view that Oliver Crisp defends (and that I follow) takes the human nature as a real body-soul composite, not as a region of the divine mind.¹⁶

The second is the theopaschite problem. If the divine mind is consciously aware of everything the human mind is conscious of (plus more), then the divine mind directly experiences Jesus' suffering, temptation, weariness, and grief. But classical Christology has always insisted that the divine nature does not suffer. The doctrine of communicatio idiomatum (the communication of properties) allows us to say that the Person of the Son suffered — but properly speaking, the suffering belongs to the human nature, not to the divine nature itself.¹⁷ On Morris's model, it is hard to see how the divine mind avoids being a direct participant in the human suffering, since it is consciously aware of every moment of that suffering as it unfolds. This is not a knock-down objection — Morris and his defenders have responses — but it does create a tension that the kryptic model handles more cleanly. On Loke's view, the divine attributes are at the preconscious level; they are not running a constant parallel feed of conscious experience that mirrors the human consciousness.

Areas of Genuine Agreement

I want to underline this because it matters. Morris is not the enemy. The actual opponents of the position I am defending in this book are physicalists who deny Christ has any immaterial mind at all, and kenoticists who claim the Son surrendered divine attributes to become incarnate. Morris stands shoulder to shoulder with Loke (and with me) in rejecting both errors. The intramural debate between the two-minds view and the kryptic view is a debate among people who all hold to Chalcedonian, dyothelite, anti-Apollinarian Christology. I prefer the kryptic model. But I would much rather have Morris's two-minds view than any version of physicalist Christology — by an enormous margin.

The Soul Connection

Now we come to the point that matters most for the larger argument of this book. Both Morris's two-minds view and Loke's kryptic view require Christ to have a human soul. Neither can survive the move to physicalism.

Think about what Morris is claiming. Christ has a human mind that is a real mind, with its own cognitive content, its own experiences, its own conscious awareness. This human mind is not a divine mind — Morris insists on the distinction. So what is it? On classical theism, a mind is the activity of a rational soul. The human mind of Jesus, on the two-minds view, is the operation of His genuinely human rational soul.¹⁸

What happens if we try to bolt the two-minds view onto physicalism? On physicalism, there is no human soul. Christ's human nature is just a body — specifically, a brain. So the asymmetric accessing relation Morris describes would have to hold between the divine mind on the one side, and a physical organ (the human brain) on the other. This is metaphysically very strange. The divine mind is supposed to "contain" the human mind, and "have access" to it — but how does a non-physical, infinite divine mind stand in a part-whole or accessing relation to a three-pound piece of neural tissue? The relation between two minds (one infinite, one limited) makes intuitive sense. The relation between an infinite mind and a brain does not.

The same problem hits Loke's model. Loke's "preconscious" divine attributes need a metaphysical home — a framework where conscious and preconscious states can be organized. The kryptic model assumes Christ has both a divine nature (where the divine attributes properly reside) and a human nature with a soul (which provides the conscious human experience). The soul is the seat of Christ's human consciousness. If physicalism is true, there is no soul to be the seat of His human consciousness — only a brain. And as I argued in Chapter 4, a brain cannot generate the unified conscious experience our minds plainly have. The infinite content of omniscience cannot be stored in finite neural connections, and the genuinely subjective experience of being Jesus of Nazareth cannot be reduced to neural firings.

So whether you go with Morris or with Loke, you need a human soul for Christ. Both models presuppose what physicalism denies. The conciliar definition of Christ's human nature — "of a rational soul and a body," ek psychēs logikēs kai sōmatos (ἐκ ψυχῆς λογικῆς καὶ σώματος)¹⁹ — is built right into the foundations of every serious modern model of the Incarnation, including Morris's. This is not a coincidence. It is a recognition of what the Incarnation actually requires.

Conclusion: A Friendly Disagreement, A Shared Foundation

Where does this leave us? Thomas Morris has given the church a genuinely useful tool for thinking about how the Son can be both omniscient and limited, both omnipotent and weary, both omnipresent and located in Galilee. His two-minds view preserves the deity, preserves the humanity, and avoids the trap of kenoticism. For these reasons, I take it seriously and respect it deeply.

But I also believe the model strains — perhaps to the breaking point — when pressed on the question of self-consciousness and personal unity. Two streams of conscious experience, each with its own self-awareness, each capable of standing in an I–Thou relationship with the other, look uncomfortably like two subjects. And two subjects, in classical Christology, look uncomfortably like Nestorianism. The kryptic model, which I will set out in Chapter 17, preserves everything Morris wanted to preserve while sidestepping these worries by positing one stream of consciousness with the divine attributes "below the surface" at the preconscious level.

What I want the reader to take away from this chapter, more than anything else, is this: Both models — Morris's and Loke's — require Christ to have a real, immaterial human soul. Whether you find Morris's view more compelling, or Loke's more compelling (as I do), or whether you find yourself drawn to Pawl's more minimalist defense of conciliar coherence (which I'll discuss in Chapter 18), all of these positions stand together against the physicalist alternative. The whole modern conversation about how Christ can be one Person with two natures presupposes that the human nature includes a genuine soul. Take the soul away, and there is nothing left for either the two-minds model or the kryptic model to work with. The Incarnation collapses into a riddle no model can solve.

That is the conclusion this whole part of the book has been driving toward. The internal Christological debate among Morris, Loke, Pawl, Crisp, and others is a family conversation. The real outsider in the room is physicalism. And in the chapters that follow, I will show why physicalism cannot even sit at the table.
