319: The Brain, a Motivation and Disgust

I think, that today is a good moment to repeat my basic assumptions in this project "The Mystery of the Brain". Not the mind but the brain. I formulated the title so deliberately.

The basic assumptions are, that there exists only one thing: matter. The brain, which generates the mind, does not generate an immaterial something, called "the mind".

The mind is somehow a feature of the brain like liquidity is a feature of water. Thus the brain is the cause of our "Supersense", which we discussed in the beginning.

We have seen a number of neurobiological discoveries and insights regarding the functioning of the brain. The present subject, the basic emotions of the homo sapiens, focus on the fact, that he a biological being.

This means that he is the result of evolution and as a species possesses general features, that you will find with any individual of the species.

Most important to understand is, that the presence on this planet of the homo sapiens as we know it today, is in relation to 5 million years of evolution, still a pretty short period and do you think that we are the end of evolution?

A second issue to keep in mind is, that the homo sapiens is inclined to believe, that its essence is defined by describing itself as a rational being.

Our focus on the basic emotions, which helped the species through the evolutionary process, is one way to show, that this Self is a bit unbalanced. The ratio is just a part of our Self and we really can question the fact that it is our dominant feature.

These are all not absolute facts, but my basic assumptions, my picture of the homo sapiens and its existence. I have proposed to assume the "truth" of these assumptions only for a pragmatic reason.

It offers the opportunity to paint a specific picture, which we definitely will scrutinize with a magnifying glass in the near future, when we'll ask the real philosophical questions about what we see in the painting.

But before we do that there are still some interesting subjects to discuss regarding our brain activity. In this case the emotion of disgust.

In the previous lecture I said "as far as we know, you only find this emotion in the repertoire of the homo sapiens", but I have discovered other sources.

The name connected with the emotion of disgust is Paul Rozin (born 1936). He is a psychology professor at the University of Pennsylvania. His current work focuses on the psychological, cultural, and biological determinants of human food choice.

In an article in PENN Arts & Science, fall1997, we read this:
"Disgust evolves culturally," explains Rozin, "and develops from a system to protect the body from harm to a system to protect the soul from harm."

At its root, disgust is a revulsion response -- "a basic biological motivational system" -- that Darwin associated with the sense of taste. Its function is to reject or discharge offensive-tasting food from the mouth (and/or the stomach),

and its fundamental indicator, the "gape" or tongue extension, has been observed in a number of animals, including birds and mammals. In humans, the characteristic facial expressions of disgust that coincide with gaping include nose wrinkling and raising the upper lip,

behaviors usually accompanied by a feeling of nausea and a general sense of revulsion. Together these behaviors and sensations facilitate the rejection of food that has been put into the mouth.

This may sound a bit confusing, as is said that eventually disgust evolved into "a system to protect the soul from harm." Animals certainly haven't a soul as is meant here.

But here we must make a clear distinction between a primary form of disgust, which solely has to do with spoiled food and -but this is questionable - with faces and other "products" of the human body,

because it is quite well possible that we can interpret these as examples of the secondary form of disgust: disgust shaped and influenced by culture. Next lecture I'll dig into the disgusting details, which will elucidate this distinction.

You don't need to come then…. ^_^

The Discussion

[13:20] herman Bergson: Thank you ...
[13:20] Doodus Moose: ... when disgust will be discussed :-)
[13:20] Bejiita Imako: hehe
[13:20] BALDUR Joubert: grin you had a cat herman.. its facial expression is quite significvant when she is disgusted... don't need a p
[13:20] herman Bergson: Well it is an amazing emotion....
[13:20] BALDUR Joubert: psychologist to find out
[13:21] BALDUR Joubert: so.. its much older than homo sapiens in evolution
[13:21] herman Bergson: Next lecture will be disgusting fun ^_^
[13:21] Bejiita Imako: well i guess all things that look taste and smell bad produce this feeling
[13:21] Bejiita Imako: also a very interesting thing
[13:21] herman Bergson: Yes Baldur…
[13:21] BALDUR Joubert: yes..but why ?
[13:22] herman Bergson: Tell me...
[13:22] BALDUR Joubert: may i ask you a question herman...
[13:22] Bejiita Imako: almost everything that decompose contain sulphur components and those in general smell very bad
[13:22] :: Beertje :: (beertje.beaumont): is it to protect our body agains spoiled food?
[13:22] Gemma Allen (gemma.cleanslate): i think he meant feces not faces
[13:22] Bejiita Imako: and what make us think that different things smell in just that way
[13:22] herman Bergson: yes Beertje..that is the basic issue
[13:22] Aristotle von Doobie (aristotlevon.doobie): making a show of disgust other that the repulsion of tainted food seems to be tantimonious to me
[13:23] Gemma Allen (gemma.cleanslate): but is it a feeling or an expression ari
[13:23] BALDUR Joubert: when you say evolution and homo sapiens
[13:23] BALDUR Joubert: for me homo s. is the result of an evolution
[13:23] Bejiita Imako: guess that sulphur components smell bad have evolved into our senses cause stuff that decompose contain them and this is not good to eat
[13:23] Bejiita Imako: a warning indicator
[13:23] BALDUR Joubert: result
[13:23] Bejiita Imako: sort of
[13:23] Gemma Allen (gemma.cleanslate): i get a feeling of disgust at certain statements
[13:23] Gemma Allen (gemma.cleanslate): like certain channels on the tv when i am watching the news
[13:23] Bejiita Imako: take h2 s for ex
[13:23] Aristotle von Doobie (aristotlevon.doobie): I suspect it is different from theprimal urge and more an expression of disapproval
[13:23] BALDUR Joubert: which happened through australopectis ..steinheim etc
[13:23] Bejiita Imako: this is the stuff that rotten eggs produce
[13:23] herman Bergson: Yes Gemma....that is an important observation!
[13:23] Bejiita Imako: H2S
[13:24] BALDUR Joubert: how themselves were products of evolution
[13:24] herman Bergson: Yes Baldur......what is your point?
[13:24] herman Bergson: Hi Zinzi
[13:24] BALDUR Joubert: so if homo sapiens is the result..changes are not evolutionary ..but development-- just like muscles develop so does the brain
[13:24] Zinzi Serevi: hello..:)
[13:25] Bejiita Imako: I guess if good things instead produced these components we might have been wired to feel a good smell from ex H"S and such things
[13:25] BALDUR Joubert: smile i have finished:)
[13:25] Bejiita Imako: a theory
[13:25] herman Bergson: That is the point Bejiita...I don't think so...
[13:25] herman Bergson: unless disgust is 100% culturally determined
[13:26] Aristotle von Doobie (aristotlevon.doobie): I think disgust at it's core is innate evolution, the rest has to be nurtured development
[13:26] BALDUR Joubert: if it were 100% cultural animals won't show disgust
[13:26] herman Bergson: It seems to be a biological feature of the animal or a homo sapiens
[13:26] Bejiita Imako: cause its otherwise weird cause why does EVERYTHING that is bad produce this smelly stuff otherwise or have nature made it that way by itself so we shouldnt eat it
[13:26] Bejiita Imako: the production of this stuff
[13:27] Doodus Moose: or perhaps we've evolved to recognize something as "smelly" - when it might not be so bad to something else
[13:27] Doodus Moose: (dogs, and what they do, for example)
[13:27] Aristotle von Doobie (aristotlevon.doobie): how do we explain limburger cheese?
[13:27] herman Bergson: well..keep in mind there are two things...
[13:27] BALDUR Joubert: has to do with survival i think.. learn not to eat what can harm you:)
[13:27] Gemma Allen (gemma.cleanslate): ♥ LOL ♥
[13:27] Bejiita Imako: ex rotten eggs shit compost ect
[13:27] Gemma Allen (gemma.cleanslate): i love it
[13:28] Bejiita Imako: is bad for u and therefor smell bad
[13:28] BALDUR Joubert: 1000 year eggs are delicatessen in china
