This question about the Ring's betrayal of Isildur brought up many different interpretations of the nature of the Ruling Ring and the extent of its ability to influence or even directly control events. Can the Ring make decisions on its own or is it merely a dangerous, but inanimate object?

    @DonBoitnott You said well programmed. They are barely able to build phones without having them explode and you want to compare them to something built and programmed by Sauron?

    @DonBoitnott That depends on how you define consciousness. E.g. the first definition on Google is: "the state of being awake and aware of one's surroundings." Is my phone awake? Sure, when I press the wake button. Is it aware of its surroundings? It has cameras, microphones, an accelerometer, and a number of senses I can only dream of. Admittedly I picked this definition at random, but if you can give me one that a (possibly as-yet-created) thinking machine can't fulfill (and which doesn't arbitrarily restrict consciousness to biologicals without justification) I'd be glad to hear it.

You cannot press the One Ring too hard, for it is of course a mythical feature, even though the world of the tales is conceived in more or less historical terms.

The Letters of J. R. R. Tolkien, #211 To Rhona Bear, p. 279

Tolkien has written no texts that I could find about the exact nature or sentience of the Ring. The Ring seems to have several passive powers that would not require sentience, such as preventing decay and invisibility. Other powers are ambiguous, as they could be more of a reaction to its environment than a conscious decision, such as changing its size. Finally, there are other passages that would imply self-awareness and conscious decision making, but even those are unsatisfactory.

Let's define sentience first: "the capacity to feel, perceive, or experience subjectively". This is not to be confused with sapience: "the ability of an organism or entity to act with appropriate judgement". A simplistic example (that some might disagree with) would be this: a table is neither, an animal is sentient, a human is sapient.

What is the Ring?

And much of the strength and will of Sauron passed into that One Ring; for the power of the Elven-rings was very great, and that which should govern them must be a thing of surpassing potency; and Sauron forged it in the Mountain of Fire in the Land of Shadow.

The Silmarillion, Of the Rings of Power and the Third Age, p. 344

There is no clear explanation as to what transferring one's strength and will to an object means. The Ring is, as far as I know, the only occurrence of this kind of ability.

It may be that the Ring becomes a extension of Sauron, but that might require two-way communication at a distance, which clearly doesn't happen (or it would have been found easily).

The Ring could also have an independent will that mirrors Sauron's, but this is getting close to giving life to an inanimate object, which only Eru can do (as with the Dwarves, for example).

The only explanation I can come up with is that Sauron's "strength and will" have given the Ring passive powers that do not require sentience (preventing decay, invisibility, lust) and that any sentient-like behaviour is merely interpretation and anthropomorphization.


The Ring is often described as having a will of its own, but most of these quotes could also be hyperbole or sourced to an unreliable character or narrator. These are the most relevant quotes I could find.

"A Ring of Power looks after itself, Frodo. It may slip off treacherously, but its keeper never abandons it.[...] It was not Gollum, Frodo, but the Ring itself that decided things. The Ring left him."

The Lord of the Rings: The Fellowship of the Ring, The Shadow of the Past, p. 73

Whether Gandalf is reliable here is not clear. He could also be anthropomorphizing it for the sake of discussion with a Hobbit. The Ring "decided things" by acting randomly, regardless of the owner's intentions.

And [Saruman] deemed that the Ring, which was Sauron's, would seek for its master as he became manifest once more; but if he were driven out again, then it would lie hid.

The Silmarillion, Of the Rings of Power and the Third Age, p. 362

This is Saruman talking at the White Council, where he is unreliable: "Curunír had turned to dark thoughts and was already a traitor in heart". This could also be interpreted as Sauron calling for the Ring rather than the Ring actively trying to get back to him.

So passed the first victim of the malice of the masterless Ring: Isildur, second King of all the Dúnedain, lord of Arnor and Gondor, and in that age of the World the last.

Unfinished Tales, The Disaster of the Gladden Fields, p. 357

This attributes malice to the Ring. I've included the quote because it is usually a sentient attribute. There's also another one about having "avenged its maker". Again, this sounds more like anthropomorphization and hyperbole to me than a statement about sentience.

Yet many have thought that the ferocity and determination of their assault on Isildur was in part due to the Ring. It was little more than two years since it had left his hand, and though it was swiftly cooling it was still heavy with his evil will, and seeking all means to return to its lord (as it did again when he recovered and was rehoused).

Unfinished Tales, The Disaster of the Gladden Fields, note 20, p. 366-367

Because of the weasel words "many have thought", I consider this to be an unreliable narrator. In any case, it doesn't imply consciousness: it might just be an Orc magnet at this point.

But as for throwing it away, that was obviously wrong. These Rings have a way of being found.

The Lord of the Rings: The Fellowship of the Ring, The Shadow of the Past, p. 79

I interpret this as a figure of speech and stretching the truth: the One Ring was found, but only after 2500 years.


The Ring is able to change its size. This happens so that it can fit on the wearer's finger, but it also seems to happen haphazardly:

"Though [Bilbo] had found out that the thing needed looking after; it did not seem always of the same size or weight; it shrank or expanded in an odd way, and might suddenly slip off a finger where it had been tight."

The Lord of the Rings: The Fellowship of the Ring, The Shadow of the Past, p. 62

Whether the Ring is changing its size consciously is unclear. Bilbo seems to imply that there was no discernible pattern as to when the Ring would do so, but that doesn't mean that he's right. It shrinked itself for Isildur, but then enlarged again two years later and got him killed.

There is an interesting quote from The Disaster of the Gladden Fields where Isildur intends to give the Ring to the "Keepers of the Three". At this time, this was Galadriel, Círdan and Elrond:

"I cannot use it. I dread the pain of touching it. And I have not yet found the strength to bend it to my will. It needs one greater than I now know myself to be. My pride has fallen. It should go to the Keepers of the Three." [...]

"My King," said Elendur, "Ciryon is dead and Aratan is dying. Your last counsellor must advise nay command you, as you commanded Ohtar. Go! Take your burden, and at all costs bring it to the Keepers: even at the cost of abandoning your men and me!"

Unfinished Tales, The Disaster of the Gladden Fields, p. 354-355

Minutes later, the Ring slips from his finger. If the Ring is sentient, then it might have heard Isildur and Elendur and decided that getting picked up by an Orc, or even being lost in the river would be a better fate. In this case, it could even be described as sapient, as it would be making a conscious decision based on new information.

But Isildur could just as well have been unlucky and experienced yet another random change in size, as described by Bilbo.

  • Having a willpower of its own in itself means it has a "consciousness" of its own. He can "feel" and "touch" and influence people and creatures around Middle-Earth. I strongly believe that the ring is sentient, it calls his master. Yes, it cannot hear nor see, but it feels and acts on its own accord, everything to reach his master. Commented Oct 6, 2016 at 21:37
  • @BalinsonofFundin It confers lust to the wearer and those around, so that it giving it away or destroying it is very difficult. As this doesn't seem to be the case for the Elven Rings (Círdan gave his freely to Gandalf), it would be coming from Sauron's will that was part of the Ring. But this is a passive power and doesn't require consciousness.

    It doesn't exactly have a will of its own, it has a piece of Sauron's will embedded within it, slightly different thing. You basically have a mini, circular Sauron. I do think the ring makes conscious decisions though, such as when to abandon a bearer, as it did with Isildur and Gollum. Commented Oct 7, 2016 at 9:05

    I read Bilbo's experience as the ring attempting to escape someone who was not bringing it closer to achieving it's desires, and Bilbo thwarting that escape. I think Bilbo had a strong enough character to fight the ring's impulses, and the ring, like most denizens of middle earth underestimated the hobbit when it chose to escape Gollom by going with him.

    +1 For a thorough examination of the issue, though I lean more toward the conclusion of "not sentient, and the language used about the Ring is hyperbolic and tends to anthropomorphize it". Like user Buzz said, a literally sentient Ring with a will of its own would go somewhat against both Tolkien's beliefs and the rules of his fictional world.

No, it was not. To grant the ring sentience and sapience would an act of creating original life. Aulë was not able to create dwarves who could move and act of their own accord without Aulë's bidding; Sauron, one of the lesser Ainur, could not create a ring that thought for itself either. True consciousness was the sole gift of Illuvatar.

So, we must conclude that what malice the ring had was merely an expression of Sauron's will. Sauron put part of himself into the ring, both his magical power and his evil hunger for might. The ring's dark "personality" was a reflection of the evil of its creator, who invested so much of himself in the artifact. Yet even though its personality was a piece taken from Sauron's, the dark lord could not actively communicate with the ring when it was away from him. His psyche was not split into two pieces that could remain in communication. We know this because, even at the greatest height of his return to power, at close of the Third Age, he could not even discern the location of the ring or who held it (until Frodo put it on in the heart of the Sammath Naur).

  • You are confusing sentience with free will. If the ring has "much of the strength and will of Sauron", why wouldn't it be at least sentient? And why would that require communication?

    To create an independent locus of sentience that is not under the direct, immediate control of its creator is ipso facto the creation of a new free will. So, since we know that Sauron does not have conscious control of the ring, it cannot have independent thought.

    Whether there is a meaningful distinction between sentience and sapience is a fundamental philosophical question. I was operating from my understanding of the Catholic belief that there is not a distinction, which would presumably be mirrored in Tolkien's legendarium.

    @isanae - the difference between the two is merely the level of intelligence. As of now, humans can't even agree if dolphins and elephants are sapient or sentient. There is no clear line here.

    +1 Tolkien said in a letter that the Ring is an "externalization" of Sauron's power and that it's passed "out of his direct control". This would imply, in my opinion, that it's not a sentient entity but a "piece" of Sauron which carries with it an echo of Sauron's will and malice. It doesn't make conscious decisions but is drawn to Sauron and draws evil creatures to itself.

Gandalf certainly talks about the Ring as though it though it had a mind of its own. He tells Frodo:

‘A Ring of Power looks after itself, Frodo. It may slip off treacherously, but its keeper never abandons it. At most he plays with the idea of handing it on to someone else’s care – and that only at an early stage, when it first begins to grip. But as far as I know Bilbo alone in history has ever gone beyond playing, and really done it. He needed all my help, too. And even so he would never have just forsaken it, or cast it aside. It was not Gollum, Frodo, but the Ring itself that decided things. The Ring left him.’

The Lord of the Rings Book I, Chapter 2: The Shadow of the Past

(Emphasis mine)

It is possible that this is just a figure of speech and the Ring was simply acting under the influence of Sauron (after all, it contains much of Sauron's power). There is certainly a metaphysical question to be solved there, but I'm not sure there is any practical difference.
