This article has an interesting psychiatric diagnosis of Gollum’s possible mental illness [HT: Eric Crampton]:
Sméagol (Gollum) is a single, 587 year old, hobbit-like male of no fixed abode. He has presented with antisocial behaviour, increasing aggression, and preoccupation with the “one ring.”… …His forensic history consists of Deagol’s murder and the attempted murder of Samwise Gamgee. He has no history of substance misuse, although like many young hobbits he smoked “pipe weed” in adolescence....
Several differential diagnoses need to be considered, and we should exclude organic causes for his symptoms. A space occupying lesion such as a brain tumour is unlikely as his symptoms are long standing. Gollum’s diet is extremely limited, consisting only of raw fish. Vitamin B-12 deficiency may cause irritability, delusions, and paranoia. His reduced appetite and loss of hair and weight may be associated with iron deficiency anaemia. He is hypervigilant and does not seem to need much sleep. This, accompanied by his bulging eyes and weight loss, suggests hyperthyroidism. Gollum’s dislike of sunlight may be due to the photosensitivity of porphyria. Attacks may be induced by starvation and accompanied by paranoid psychosis....
Gollum displays pervasive maladaptive behaviour that has been present since childhood with a persistent disease course. His odd interests and spiteful behaviour have led to difficulty in forming friendships and have caused distress to others. He fulfils seven of the nine criteria for schizoid personality disorder (ICD F60.1), and, if we must label Gollum’s problems, we believe that this is the most likely diagnosis.
Certainly a plausible diagnosis. However, as a law and economics scholar I can’t resist pointing out the possibility that Gollum was acting rationally all along, given his somewhat unusual preferences. After all, getting and keeping the Ring of Power was Gollum’s only way to achieve a measure of wealth, power, and a long lifespan far beyond that of other Hobbits. He successfully kept possession of the ring for decades, and nearly recovered it in The Lord of the Rings, despite facing huge obstacles.
If we assume that Gollum valued long life, power, and wealth above companionship, socializing, and conventional morality, his actions seem perfectly rational. True, the Ring didn’t ultimately make him wealthy. But it was reasonable to assume that it might when he first stole it. And it did give him a much longer life and greater power than he would have had otherwise. As for his supposed multiple personality disorder, perhaps inventing a second personality was a good way to pass the time during his long years of living alone. When he met Sam and Frodo, the supposed second personality was a good excuse for evading responsibility for his deceptions and efforts to steal back the Ring. If not for the alternate personality, Frodo might have let Sam kill Gollum or drive him away. Finally, Gollum’s theft of the ring and his obsessive guarding of it afterwards was arguably a rational response to the extremely poor enforcement of property rights in Middle Earth.
Maybe Gollum is an example of Bryan Caplan’s thesis that many seemingly insane people are not irrational, but merely have unusual preferences. In the same article, Caplan also explains the rationality of Denethor, another Tolkien character sometimes diagnosed as insane.
In the comments to the psychiatry article, Gollum himself takes a potshot at his psychiatric critics:
Nasty psychiatrissstss! Hates them, my precious! They locks uss up in padded cell! They makes uss look at inkblotsss! Tricksy, sly inkblotsss! Nasty Elvish pills burnsss our throat!

The article is a 3-minute read, and the funniest bit is the footnote, relating to how the man co-wrote the article with his 2 (very!) young sons.

From Tolkien’s words we do not know, but only assume, that Smeagol perished with the ring. Maybe there was a little more to Frodo vacating Middle Earth than Tolkien felt comfortable telling the reader. Additionally, we only assume the ring was devoured.
Hmmm...makes PersonFromPorlock’s observation a little more sinister. I had always assumed James Carville was simply Cruella De Vil’s nephew. Also, doesn’t George Soros look kinda “stretched?” Ginsburg could pass for a Nazgul, ya know.

As to your analysis, there is a story:
A law professor was driving by an insane asylum and got a flat tire. He got out, jacked up the car, unscrewed the bolts and carefully put them in the hubcap. As he was bringing the spare around, he stepped on the hubcap and all the bolts went flying down a hill. “Now what will I do?” he wondered aloud. An inmate, who’d been watching, said, “just take one bolt from each of the other wheels. That will do until you can get to a service station.”
The professor said, “that’s a good idea! How odd that you’re in an insane asylum.”
The inmate said, “look, I may be crazy, but I’m not stupid.”

It might be odd to describe as “perfectly rational” someone who regularly has conversations with an inanimate object, even when that object isn’t present.
Sure, Gollum enjoyed an unnaturally prolonged life. But he spent the majority of it in a dank cave, eating raw fish and hiding from goblins. Quite literally, hundreds of years of a life of complete boredom interrupted by moments of terror, with nothing to bring joy except inexpertly prepared sushi and the occasional murder of a savage. I dunno, not a good trade in MY book. The life of a law professor must be REALLY terrible to make that seem attractive!

Gollum was not “preoccupied” with the One Ring. He was existentially obsessed with it. This is because the Ring was evil– and sentient. Sméagol without the Ring was a quirky, slightly unsocial hobbit-like creature. With it he became Gollum.
I would recommend against trying to cope with evil by using medications or therapy. Or laws, for that matter.

Funny how the obvious solution evaded the elites in Middle Earth. :P

Gollum succeeded where Frodo failed.
And I’m surprised at Prof. Somin. Gollum wasn’t after power or wealth. He was simply trying to protect his property rights. (Sauron was also interested in preserving his property, but for him the ring was a means to an end. For Gollum, it was more of an end in itself.)
I’m also a bit concerned that someone would try to do a psychological profile of Gollum without taking into account the extensive torture he went through at Mordor.

Sarnac says:
Regarding Gollum’s diet: he ate rabbits also, thus presumably other small land-based wild game, especially in those centuries when he could sneak up on things invisibly.
Regarding the eagle-flight-solution to ring-destruction: any incoming airstrike by the forces-of-light would have been detected by Sauron’s “eye” and the Nazgul airpower available to the forces of darkness could have dispatched the incoming eagles.
Separately, the OneRing could not simply be thrown in to the lava because there was a cave to walk through to get to the interior of Mount Doom. Given a highly-visible incoming airstrike, Mount Doom would have been swarmed by Orcs etc on foot.
The various battles etc were a necessary solution to the problem of distracting a nearly-all-powerful pseudo-deity from trivially blocking the slow-end-run-by-the-pipsqueak.
Sometimes war IS the answer to an otherwise unsolvable problem.

I was only able to access a portion of the original piece, which seems to me to be significantly flawed.
Gollem’s forensic history is far from limited to Deagol’s murder and the attempted murder of Samwise Gamgee. I don’t have time to check for LoTR page references but I recall that Sméagol was expelled from his native clan of Storrs on suspicion of serial infanticide. Not long after Sméagol stole the Ring from Deagol, Sméagol acquired the practice of using the Ring to kidnap infant children of his own clan of Storrs. These children were taken from their cradles. If memory serves, Sméagol would then strangle and eat the kidnapped infants. This particular behavior would seem to place Gollum beyond the extremes of pedophilia and/or a serial mass murderer. The only historic figure that comes to mind who would seem to be comparable was the predetary homosexual pedophiliac and serial mass murdered of Jewish children (and perhaps significantly) Nobel Peace Prize winner Yassar Arafat.

While I did laugh at that comic, to Tolkien’s credit, that would likely not have worked. Recall that the Nazgul were mounted on flying “fell beasts” after the little incident at the Ford of Bruinen. The eye of Sauron could probably have spotted an eagle flying in at some distance, and send up the Nazgul with sharp pointy things to deal with it (or for that matter, depending on how high the eagles fly, they could have had orc archers deal with them).
Edit: and apparently Sarnac already pointed this out. Good to know I’m not the only LotR geek to think this way.

That’s why Frodo doesn’t ride on the back of the Eagle, he gets carried in its claws. If Frodo won’t drop the ring, the Eagle drops Frodo and the ring into the volcano.
And if the Eagle hesitates, Gandalf is standing on the tallest tower of Minas Tirith, ready with a lightning bolt to ensure that if necessary, the Eagle falls into the volcano too. Because Gandalf at that point isn’t realistically going to get the ring if he hesitates, he at least is likely to not be tempted :)

ITA! Substance addiction is precisely the problem here, it simply isn’t an ingested substance that is being addiction.
Then again, an alternate diagnosis of mental illness due to demon possession also has a lot of merit to it and is well established in literature and scripture, if not in the DSM-IV. The facts may be insufficient to distinguish between these two forms of causation, or demon possession may be a mechanism by which the substance addiction acts.
