I was at dinner the other week with a voluble atheist religion professor who, in defense of a materialist view of the human mind, raised the subject of Phineas Gage (1823-1860). Ah yes, the man whose personality changed completely after a horrific accident, a staple of Introductory Psychology.

Anyone who has taken Psychology 101 or read popular neuroscience books has probably heard Gage’s story, which upholds the “frontal lobe” theory of personality. (= You are your frontal lobes.)

The story is that in 1848, a tamping rod went through Gage’s head and totally changed his personality. He was “no longer Gage.” Which demonstrates that the mind and the self are an illusion created by the buzz of neurons in the brain. A textbook case.

I pointed out over dinner that there are good reasons to doubt this story. The prof was, of course, withering. Hundreds and hundreds of psych texts have told Gage’s story, he informed me, so how could it be false or questionable?

Well, I have written for newspapers most of my adult life, and one thing I know is this: Printing more copies of any type of information does not make it true. It makes it more widely disseminated.

A distant relative of the Textbook Case sent me an article by University of London historian Zbigniew Kotowicz, “The strange case of Phineas Gage,” History of the Human Sciences (Vol. 20 No. 1, pp. 115-131), which offers the story you and six hundred others in Psych 101 may not have heard.

First, let’s go over exactly what happened: Gage, 25, was foreman of a gang blowing away rock to lay rail for the Rutland & Burlington Railroad near Cavendish, Vermont. Gage’s job was laying explosives. On September 13, 1848, he was momentarily distracted, and the explosive detonated, pushing the tamping rod through his head. The rod was 5.9 kg (13.25 lb.), 1.05 m (over 3.5 ft) long and 44.45 mm (1.75 in) across. As Kotowicz tells the story,

It entered beneath his left cheek, passed behind the eye, pierced the base of the skull, went through the front of the brain, and fell on the ground over 100 feet (30.4 m) away. Covered in blood and brains.

Remarkably, Gage did not lose consciousness. He was able to move and speak. He took about two months to heal. He finished his recovery at his mother’s home where, Harlow recounts, he entertained his nephews and nieces with fanciful tales, and looked after farm and domestic animals.

In all, three contemporary reports were written about Gage in professional journals:

1) A report given to a medical audience by his doctor John Harlow, three months after the incident. The famous passage in physician Harlow’s account of the changed personality (“no longer Gage”) referred to that period and not to the rest of his life. More on that presently.

2) A report by Harvard surgeon Henry Bigelow, who observed Gage over a period of two months somewhat more than a year later and took a life mask of his face (pictured above). According to Bigelow, Gage was calm, “talking with composure and equanimity of the hole in his head.” and his behaviour did not fit the profile of a psychopath.

3) A report by Harlow seven years after Gage’s death, based on information from his family.

The lecture room legend

And after that? After his death, Gage slowly morphed into the lecture room legend. According to Kotowicz,

… most of the subsequent descriptions of Gage were based on hearsay. Some of them were quite florid; Gage was portrayed as having fits of temper when not getting his own way, as being disinclined to work, as having a reduced libido, as being an aimless drifter and so on. A typical description of him would say that before the accident Gage had been a diligent, reliable, polite and socially adept person: after his accident, he subsequently became uncaring, profane and socially inappropriate in his conduct.

For example, at Neurophilosophy, we learn:

Thus, the damage to Gage’s frontal cortex had resulted in a complete loss of social inhibitions, which often led to inappropriate behaviour.

The documentary evidence

Kotowicz begs to differ:

However, after examining closely the accounts of Phineas Gage as given by the doctors who knew him, Harlow and Bigelow, one must conclude that the supposed psychopathic traits are not evident.

The drastic discntinuity was not so much between Phineas Gage pre- and post-tamping rod but between Phineas Gage (1823-1860) and the lecture room legend.

What we can learn from contemporary accounts of Gage’s post-trauma life is this: For a while after the accident, he drifted, and even ended up briefly in P. T. Barnum’s freak show, exhibiting himself and the tamping rod. But he then settled down and worked a year and a half in a stable. Later, he went with a friend to Valparaiso in Chile where he cared for horses and drove a coach and six for eight years.

Kotowicz points out the obvious,

Working in stables is not a job for a psychopath. Horses are very sensitive and they require discipline and calm; they have to be attended to regularly, seven days a week, and work begins early.

 

(They are also apt to bite, kick, rear, and stampede, if startled or abused.)

Of course, Gage had been catastrophically injured, and about twelve years later, the effects caught up with him. By February 1860, back from Chile, he continued to try to work on farms while living with or near his mother, who had moved to San Francisco. But he began to have frequent epileptic convulsions. They worsened, and he died on May 21, 1860. No autopsy was performed, but Harlow later exhumed the body and recovered Gage’s skull and the tamping rod.

What no one stopped to think about

Kotowicz’s account diverges still further from the lecture room legend:

… what is really amazing is that none of the many who comment on the case seem to have ever stopped for a moment to think what Gage might have looked like after the accident.

A team of researchers using modern computer techniques decided to try to reconstruct his post-accident face, “borrowing” the face of a student whose life mask looks like the one taken of Gage by Bigelow. (A life mask gives a correct image of shape but not of facial mobility.)
The reconstruction they provide would certainly startle a new acquaintance. Kotowicz contends that, to the extent that Gage was unsettled, it was probably mainly due to his horrifying disfigurement and not to psychopathic tendencies:

First he meets his workmates. Their attitude towards him has changed; now they turn their eyes away, they are not the same easygoing fellows; and the girls do not laugh and flirt with him as they did. And if there was some lassie that he was particularly fond of, well . . . all this must be really difficult to take. Someone will look at him, and we can imagine him snapping back, ‘What are you staring at, you bastard?’ And there are also those who are only too ready to give advice, but giving advice to someone in Gage’s predicament is a risky business. Again, we can imagine him telling them to go to hell. Very ungrateful; definitely, to ‘his friends and acquaintances’ he is ‘“no longer Gage”’. It is different at home, at his mother’s, where the final recovery takes place. He entertains his nephews and nieces by making up fantastic stories; they must love Uncle Phineas, and they do not care about his scars. He also grows fond of pets, especially dogs and horses. Animals not only do not care about his scars, they do not even see them. Gage quickly becomes attached to them. But the outside world of adults cannot be ignored. Gage needs to go back to work. And here comes the first tangible blow: he is not wanted back …”

But he must work; he is a working man.

“As we have seen, Gage finds employment in a stable. Work is hard but it is most likely Gage does not mind, he probably shuns others and keeps to himself (and who in his place wouldn’t?). It may well be that like many before him and many since, he has decided that he is better off in the company of animals than fellow humans. For the rest of his life he will work with horses. After work in the stable, Gage leaves for Chile to set up a coachline. He is ‘occupied in caring for horses, and often driving a coach heavily laden and drawn by six horses’ (ibid.: 415). This means he has strength, dexterity and an excellent relationship with the animals; Gage has evidently mastered his metier.

And, as we have seen, he worked right up to the end.

But, as we have also seen, psych profs didn’t need a working man who had independently adapted to his disability; they needed an aimless drifter, so,

… the image of Gage the psychopath has emerged; he is a contemporary construct. Harlow’s words telling us that the ‘equilibrium or balance, so to speak, between his intellectual faculties and animal propensities, seems to have been destroyed’, that he indulged ‘in the grossest profanity’ and that he was ‘no longer Gage’ are now routinely quoted, but nothing else about him is ever mentioned. In the myopic vision of the neurosciences, Phineas Gage has been reduced to a witless psychopath. It seems that the growing commitment to the frontal lobe doctrine of emotions brought Gage to the limelight and shapes how he is described. The psychopath Phineas Gage has now entered scientific folklore; according to a calculation from recent years (Macmillan, 2002: 333) some 60 per cent of psychology textbooks quote it as one of the first cases where personality change occurred after damage to the frontal lobes.

So Kotowicz asks, a century and a half – and hundreds of textbooks – later

Was this a life of a psychopath? Did be behave dismally? One neuroscientist claims that ‘Gage lost something uniquely human, the ability to plan his future as a social being’ (Damasio, 1994: 19). He asks, ‘Did he have a sense of right and wrong?’ (ibid.: 18), which is nothing short of asking whether he had a soul, and he wonders whether Gage was ‘responsible for his acts’ (ibid.). This is a slur on the dead man’s good name. Harlow does not report a single act that Gage should have been ashamed of, let alone made ‘responsible’ for. There is no mention of violence, theft, abuse; not even something as vague as ‘irresponsibility’. There is coherence and dignity in the way Gage dealt with his predicament. He deserves deep respect.

Gage indeed deserves deep respect. The materialist psychology texts routinely purveying false knowledge (“the things we know that ain’t so”) – not so much.

In recent years, the Gage industry has become more nuanced, perhaps in line with a less materialist emphasis on the mind, though many kind readers of this b log doubtless took Intro Psych before that change occurred.

The strange case of Phineas Gage
Zbigniew Kotowicz
Department of History, Goldsmiths College, London, z.kotowicz@gold.ac.uk

The 19th-century story of Phineas Gage is much quoted in neuroscientific literature as the first recorded case in which personality change (from polite and sociable to psychopathic) occurred after damage to the brain. In this article I contest this interpretation. From a close examination of the story of Gage I have come to conclude that first of all there was nothing psychopathic in Gage’s behavior and that changes in his life are more coherently explained by seeing them as his way of dealing with disfigurement that he suffered after the accident. This is not just a matter of reinterpreting a case. The way Gage has been presented and discussed in neuroscientific literature suggests that the new paradigm of neuroscientifically oriented psychiatry may lead to an erosion of clinical knowledge.

Key Words: brain damage • clinical experience • disfigurement • neurosciences

Here is another Gage scholar, Malcolm Macmillan of Deakin University School of Psychology in Victoria, Australia, where he maintains a Phineas Gage page. He writes:

Most of the accounts of Gage’s life after 1848 are strange mixtures of slight fact, considerable fancy, and downright fabrication.

He deals with unanswered questions here.

Images of the injury to Gage’s skull

Discussions in journals over the years are here. Here’s a typical modern materialist account.

More stuff we know that ain’t so: 19th century Christians opposed anaesthetics in childbirth; Mediaeval people thought Earth was flat; Copernicus demoted Earth from the centre of the universe.

mentok [31]: Looks like the Egyptians were right all along: The first organ removed was the brain. The Egyptians believed that the brain was of little importance and it was thrown away when removed... With the corpse lying on its back, they inserted the hook through the nose and managed to pulverize the brain tissue into an almost liquid state. Then they turned the body over onto its stomach, and the liquefied brain tissue drained out through the nostrils. Palm wine and frankincense was used to flush and clean the cranial cavity. - MummificationJT

Some people have almost no brain at all due to a condition they are born with called hydrocephalus. An example is a person whose skull was filled with fluid with the skull lined by a millimeter of brain substance, still he was in college with an honours degree in mathematics and wasn't even aware he had virtually no brain, see http://www.flatrock.org.nz/topics/science/is_the_brain_really_necessary.htmmentok

Why are we wasting our time debating a completely discredited theory (Cartesian dualism) which most Christians don't accept and which the Christian Church has never accepted, anyway? The favored theory of the Catholic Church, for instance, is hylomorphism, originally developed by Aristotle and Christianized by St. Thomas Aquinas. A further discussion of hylomorphism may be found in this article by by Fr. John O'Callaghan. The author demonstrates that belief in a soul does not imply substance dualism - the belief that soul and body are two things. On the contrary, every human being is a unity. An organism's soul is simply its underlying principle of unity. The human soul, with its ability to reason, does not distinguish us from animals; it distinguishes us as animals. The unity of a human being's actions is actually deeper and stronger than that underlying the acts of a non-rational animal: rationality allows us to bring together our past, present and future acts, when we formulate plans. When Aquinas argues that the act of intellect is not the act of a bodily organ, he is not showing that there is a non-animal act engaged in by human beings. He is showing, rather, that not every act of an animal is a bodily act. Hylomorphism claims that some acts that persons perform (acts of the intellect and free decisions) are non-bodily acts. But "personality" is much broader than these. Hence we should not be surprised at findings that personality is linked to the brain. In any case, an individual's personality may change significantly during their lifetime, even without brain injury; yet we still say they are the same person. Indeed, personality can change as a result of a voluntary decision. My wife tells me that she was a very shy child until the age of ten - and then she suddenly decided to change her personality. Everyone remarked upon how different she was. Speaking for myself, I would not be one whit perturbed if my personality does not survive my death - indeed, I rather hope it doesn't! Thus the following comments are attacking a straw man: JayM:
If mind is independent of brain, one would not expect a brain injury to change personality (as opposed to simply reducing function, for example).
JTaylor:
That suggests then that personality is formed and governed by somatic and environmental factors - and is not therefore not linked to an immutable soul ...
The above comments are problematic only for dualists who hold that all mental phenomena (thoughts, decisions, memories, mental images, emotions, feelings and sensations) reside exlusively in an immaterial soul. A hylomorphist, by contrast, will happily grant that the following are all acts we perform with our brains and nervous systems: seeing, hearing, touching, smelling and tasting; feeling happy, sad, angry or afraid; imagining something; and remembering something. What about the evidence that brain damage impairs intellectual function, as described in this article by Joanne McGee? (Thanks for the link, B. L. Harville.) We have to keep in mind that abstract thought is a very high-level operation, which cannot occur unless a whole host of lower-level activities are occurring. The brain is a magnificent information processor. Hence, damage to the information processor can mean that the intellect has nothing to process. It is not that the intellect has ceased to be; it is lower-level functions that are at fault here. For those readers to whom the prospect of bodiless survival appears too dismal to contemplate, the Christian message is: well, it should! I suspect that a disembodied soul could not deliberate about anything without a massive degree of Divine assistance to make up for the loss of a brain. In any case, this artificial mode of post-moterm existence is but temporary. What a Christian looks forward to is resurrection: a permanent reunion of soul and body. Finally, this article by Professor Alfred Freddoso is well worth reading for any Christians who may be tempted to jettison the doctrine of a dismebodied soul altogether: http://www.nd.edu/~afreddos/papers/soul.pdf .vjtorley

JDH, The philosophy of free will is more nuanced than you suppose. Being a materialist does not require believing that free will is an illusion. Even if it did, it does not follow that persuasion is futile or that people are incapable of making decisions.skeech

I agree with Borne@18. I have never understood the person who claims to be a strong advocate of materialism. If one truly believes in materialism, then one must believe that all supposed free will is an illusion. If you believe that free will is an illusion, what on earth are you doing trying to convince me to make a decision you say I can't make!!!! Either materialists truly do not believe what they say they believe, or they do not accept the logical consequences of their beliefs. Either way, its a strange position to take. If they are right all arguments about the subject are moot. Evolution may have occurred. But purpose can not be created by evolution.JDH

Harville,
For example, damage to the orbitofrontal area can lead to the brain injured person doing “what they feel like doing at any point in time, without concern for social taboos or legal prohibitions. Personality changes may include a cheerful lack of concern about the illness, inappropriate joking, and other disinhibited behaviors.” There is much more information on the internet on the subject if you look for it.
I think I'm with uoflcard on this subject, so much as being inebriated can induce such behavioral changes. I suppose the only way to truly test the reality of an immaterial mind is to observe cases that would completely disconnect it from the brain, such is the case in some pretty well documented near death experiences. I'm at work right now so I don't have the time to link to a good example but when I get home I should be able to provide some useful information.PaulN

If my brain is merely a meat computer (as the materialist reckons), and my personality changed due to a brain injury, would I know that it was abnormal? Exploring a different avenue, if personality (a colloquial term for consciousness) is merely an emergent property of a brain, how much brain is required for a normal personality to be present? A whole lot? Not necessarily. A half? Maybe. Practically none? Impossible... right? I'm sure glad we've got all that mind vs. matter thing all sorted out. Or it'll be sorted out soon. Maybe. Possibly. At any rate it can't be dualism, because like germ theory, it implies that some weird living things that are invisible to the naked eye exist, when it's a well-established, time-tested fact that unintelligent, non-living, natural humours determine our state of health.angryoldfatman

"Most personality traits are probably laid down pretty early, and are difficult to change. They can be due to inherited or acquired metabolism, to birth order*, to social and cultural circumstances …" That suggests then that personality is formed and governed by somatic and environmental factors - and is not therefore not linked to an immutable soul (the characteristics of which would presumably not be effected by materialistic factors such as birth-order or metabolism).JTaylor

If “you are nothing but a pack of neurons”, as Crick enjoined, then who cares what a pack of neurons says or does?!
We care what other people say, think and do. If they are "packs of neurons", then it follows that we care what "packs of neurons" say and do. Your comment betrays your assumption that thoughts and emotions cannot be genuine if they are physically instantiated. This is simply a prejudice.
No decision is ever really made, there are only just organic circuits being engaged, branched and turned on or off.
That's like saying that a computer can't really add up a list of numbers -- it's just a bunch of transistors being turned on and off.skeech

See "Psychiatric disorders and traumatic brain injury" by Schwarzbold et al., Neuropsychiatr Dis Treat. 2008 August; 4(4): 797–816, especially table 1. Also, see Can Traumatic Brain Injury Cause Psychiatric Disorders?, by van Reekum et al., J Neuropsychiatry Clin Neurosci 12:316-327, August 2000. In general, the literature supports a causative relation between some psychological/psychiatric disorders and brain injury. The specific causes are of course hard to pin down, but an immaterial mind does not seem to be a serious alternative. The proposed causes for personality change are all material.David Kellogg

Most personality traits are probably laid down pretty early, and are difficult to change. They can be due to inherited or acquired metabolism, to birth order*, to social and cultural circumstances ... A catastrophic brain injury is not a guided intervention for personality change. Most people probably respond to the injuries using those life strategies they can still remember and practice. Lack of inhibition in some - not all - brain-injured people comes, I gather, from loss of the ability to monitor others' reactions closely. We are all less inhibited when we are alone. That is why we seek what we call "privacy" in certain circumstances. So the loss of ability to monitor others closely would lead to a tendency to behave as if one was alone when was in fact in company. I don't think I will spend much time looking for lots of information on the Internet. Quality is much more important here than quantity - as the Phineas Gage case abundantly demonstrates. *Men tend to be more dominant than women, but eldest sister may be much more dominant than baby brother, in a large family.O'Leary

Personality changes occur more often than we tend to think. It is common in parents that have lost a child, for example, for one or both of them to be so devastated that they experience some personality change. They just are never the same afterwards. Something has broken inside and it is clear that it does not start with the mere physical brain - mere matter and energy! That's why divorce rates for couples that've lost a child are up around 80%. I witnessed this myself. And I believe it's understandable without resorting to the materialist's mind=brain dogma. Just getting drunk or stoned induces temporary personality changes. So? The mind=brain doctrine is not supported by these things at all. It is just as readily explained under a non-materialist paradigm. Change in the brain will often induce some kind of change in conduct whether it be temporary or permanent damage. This would be normal simply because of the intimate connection between mind and brain, and that even though materialist dogma isn't true! BL Harville:
But if the mind, or personality, is seperate from the brain then personality change should never happen as a result of brain injury.
That simply isn't so, as I explained above. Drugs and booze can induce personality changes. Now, suppose mind is not equal to matter; still the bare fact of there being an intimate connection with the physical brain is certain to produce some change in personality and/or behavior in some cases. The brain may not respond to the mind! Thus a change in behavior is explicable under either paradigm! So the point is moot. If parts of ones memory recall, intellectual abilities, speech capacity, etc. are disabled the brain would no longer be responding to the mind and that even against ones will! Indeed, how does one measure will in materialism? Well you don't because it doesn't actually exist under that paradigm. We are thus all organic robots under the illusion of having will. And this we are told most assuredly by all the materialists in the clearest of terms! Now, suppose these materialist pundits are truly right, why should anyone care what anyone else thinks? Its all just electro-chemical reactions to inner and outer stimuli and personality doesn't really exist as an attribute of choice at all! If "you are nothing but a pack of neurons", as Crick enjoined, then who cares what a pack of neurons says or does?! It's all without purpose or will in the end. It's all an illusion. All debate, proselytising and quarreling over anything at all becomes utterly useless. So atheism and materilaist mind/brain dogma are ideas that don't matter. Under that doctrine the thoughts of the materialist and the thoughts of the theist would be equally nothing but movements of matter & energy - just moving differently from one brain to the next. Logical conlcusion of this? No decision is ever really made, there are only just organic circuits being engaged, branched and turned on or off. That spurious doctrine reduces all life to utter meaninglessness destined for perfect oblivion. And that means that materialism itself is utterly futile as an idea.Borne

This is on the assumption that personality is also separate from the body.
Moral behavior is an aspect of personality, and so many Christians want to believe that the personality has an extracorporeal basis. Otherwise, how would it make sense for God to reward or punish the soul at the time of death for behavior that is the responsibility of the body? When Jesus told the thief "Today you will be with me in Paradise", he clearly wasn't talking about the thief's body. This accounts for the persistence of dualism among most Christians, along with their fierce resistance to the implications of modern neuroscience. Interestingly, I have also encountered Christians who admit that the body is the seat of the personality, but who say that this doesn't matter because it is the body that is resurrected at the Final Judgment and then placed in heaven or hell. For them, the time between death and the Final Judgment is a dreamless oblivion. I don't know how these Christians reconcile this idea with the story of Jesus and the thief. Perhaps they consider the thief to have been an exception to the normal rule.skeech

To me, personality is the outward projection of a person, and it can obviously be affected by physical interference (drinking alcohol, for example). I don’t know who denies this possibility.
Add to that the theory of humours which was very influential in ancient, medieval and earlier modern times, and I think we can safely say that it's always been believed that physiological changes can affect personality.anonym

The story of Phineas Gage is an interesting one and it does appear there is more to it than first thought. But interesting though it may be, does it change what is currently known about the consequences of Traumatic Brian Injury (TBI)? I think Denyse's and PaulN's ideas about facial disfigurement are interesting, but are they supported by any clinical data? Remember too that many people who receive brain injuries are not disfigured (e.g., blunt blows to the head) and appear the same. I could not find any information on how disfigurement plays a part in behavior change for TBI patients. That it isn't to say it doesn't exist, but it is not easily found through Google search at least. Also, Denyse's comments about the people she knows, insightful that they may be, are really anecdotal and we have no way of verifying them. But there are reports that suggest that long-term well-being is not in fact the case with every TBI patient: "A close relative of each of 42 severely head injured patients was interviewed at 5 years after injury, following initial study at 3, 6, and 12 months. Persisting severe deficits, in some cases worse than at 1 year, were primarily psychological and behavioural, although minor physical deficits, for example in vision, were also common. Relatives were under great strain; significantly more so than at 1 year. The best predictor of strain in the relative was the magnitude of behavioural and personality change in the patient."

Not trying to be pushy or anything, but with every thing now taken into consideration with the Gage case, can you provide any examples of said numerous cases that are completely disconnected from amplified insecurities due to facial disfigurement or other relevant causes for sporadic changes in behavior?
Try reading the very first link in the google search I provided above. It lists cognitive changes in brain injured patients that are not related to pain or embarrassment due to disfigurement. It also discusses how injuries to different parts of the brain lead to different changes in personality. For example, damage to the orbitofrontal area can lead to the brain injured person doing "what they feel like doing at any point in time, without concern for social taboos or legal prohibitions. Personality changes may include a cheerful lack of concern about the illness, inappropriate joking, and other disinhibited behaviors." There is much more information on the internet on the subject if you look for it.B L Harville

joshua (10) - I dont't know if that's what it is saying. I think it's just saying the severity of the injury does not have an impact on the change, but that there are changes.uoflcard

In any case, the burden on the materialist is to show that mind is nothing but brain and therefore injury to brain injures the mind. For the dualist to challenge this it is enough to exhibit a counterexample, not that brain injury never affects personality.
You have that backwards, Dr. Dembski. If mind is independent of brain, one would not expect a brain injury to change personality (as opposed to simply reducing function, for example). From a materialist perspective, not all injuries would be expected to change personality. A single example of personality change resulting from physical change to the brain is not consistent with dualism, however. JayMJayM

But if the mind, or personality, is seperate from the brain then personality change should never happen as a result of brain injury.
This is on the assumption that personality is also separate from the body. To me, personality is the outward projection of a person, and it can obviously be affected by physical interference (drinking alcohol, for example). I don't know who denies this possibility. It is even widely commented on in the Bible.uoflcard

BL Harville: You provided a google search for refutation. Interestingly the sixth hit from Pub Med disagreed that head injuries changed personalities... Abstract A close relative of 55 severely head injured adults rated the personality of the patient at 3, 6 and 12 months after injury, using a Yes/No judgement, and analogue scales comprising bipolar adjectives. The relative assessed the "current" as well as the "premorbid" personality at each time. Personality change was associated with many negative scores on the analogue scale, and increasing negative scores were associated with high "subjective burden" on the relative. Severity of injury (post-traumatic amnesia) was of no significance in predicting the extent or pattern of personality change. Here is the link to the article that really questions the emotional/social impact of head injuries. (The sixth hit on Harville's google search)joshuabgood

So basically people blew Gage's behavior change out of proportion in an attempt to explain his perceived psychopathic social tendencies with materialist ideologies. This doesn't surprise me at all, especially after realizing how a self-conscious individual would be affected by a tragic accident that resulted in a disfigured face. His comfort level and behavior pattern around children and animals basically spells that out. I can't see how this case would differ from the cases on the multitudes of burn victims out there. I think this goes more to show how followers of such a desperate world view will cling to the smallest conceivable "evidences" to justify their beliefs and then use powerful imagery and colorful rhetoric to disseminate it upon the rest of the establishment. This applies to anything from constructing an entire skeleton from a simple "skull fragment" to explaining psychopathic behavior in brain trauma patients to forging pictures that falsely represent embryonic similarities in different stages of development. My rhetorical question is, how do they continuously get away with it for so long without any type of intellectual repercussions or adjustments, compared to whenever an accurate explanation from a different world view is presented, it's immediately criticized and off-handedly dismissed? Also, Harville @2
Phineas Gage is just the most well known case. There are numerous cases of personality change after brain injury. It has been witnessed by numerous doctors and family members.
Not trying to be pushy or anything, but with every thing now taken into consideration with the Gage case, can you provide any examples of said numerous cases that are completely disconnected from amplified insecurities due to facial disfigurement or other relevant causes for sporadic changes in behavior? (I.e. having bipolar disorder, being a self-conscious burn victim, various other pre-existing mental disorders etc...)PaulN

O'Leary, Certainly not every injury to the brain is going to lead to personality change. It would be very odd if that were the case. But if the mind, or personality, is seperate from the brain then personality change should never happen as a result of brain injury. By personality change we're talking about something more than being embarrassed about one's looks from disfigurement or disagreeableness due to pain. A glance at the google search I provided above will show that a great deal of research has been done in this area. You can't debunk the entire field of study by attacking only the Gage case.B L Harville

anonym (1) - that was ridiculous and entertaining. and of course there are the obligatory strawmen, like anyone who denies Darwinism denies evolution altogether. Yes, evolution is a proven fact. Heck, look at your dog for proof of evolution. Proof of darwinian mechanisms producing extremely complex microbiological structures, meta-information in the genome, redundant yet independently systems is what is lacking. For a while I was on the borderline of atheism. I was truly agnostic towards my original faith (Christianity). But the more I really though about neo-Darwinian theory, the less sense it made. I can now honestly say I don't have enough faith to be an atheist.uoflcard

B L Harville, it might be helpful to specify what we mean by personality change after brain injury. It seems apparent to me that Gage's main problem after the initial period of learning to cope with his injury was that he was a fright to behold. (At least to humans; horses wouldn't notice.) So - being by inclination a working man and not inclined to sponge - he took to stabling and driving horses until he succumbed to the late effects of his injuries. Apart from the early stages of getting used to the unimaginable, we don't have reliable early information that his personality really did change much. Which is why it is troubling to me that he should be the Textbook Example. Perhaps some people's personalities do change, but it does not appear to be inevitable, even with catastrophic injuries. If my own experience of brain injured acquaintances may be considered, many things change when a person who was formerly, say, a senior civil servant or a popular filmmaker becomes a disfigured invalid. Their early stage rages against caregivers are best interpreted as reluctance to accept a much humbler, more dependent style of life rather than as a personality change. Usually, when I meet them years later, they are largely as they were - learning to live with what they cannot change and make the best of it. The surprising thing - to me - has been that the personality did NOT change much.O'Leary

Have other people’s personalities fundamentally changed through brain injury? That may be, but please provide some case studies.

Thanks Denyse for posting this. I recently saw the conventional cant about Gage recycled by Patrick Grim for some Teaching Company lectures on philosophy of mind. B. L. Harville: Please elaborate. Phineas Gage is the most well known case of what? Fundamental change in personality and moral outlook? That's precisely the point in question. Have other people's personalities fundamentally changed through brain injury? That may be, but please provide some case studies. In any case, the burden on the materialist is to show that mind is nothing but brain and therefore injury to brain injures the mind. For the dualist to challenge this it is enough to exhibit a counterexample, not that brain injury never affects personality.William Dembski
