Which meaning of the word 'scientism' do you have in mind?

Observations, in and of themselves, never resolve *any* issues. Explanations that rely on observations can. Many scientists either don't know this, or ignore it. So if you see a scientist talking about a study proving something, and you don't see any explanations of how the observations demonstrate the purported conclusion, it's scientism.

I think that part of the problem is that different groups are using the same word ("Pain") and attaching different meanings to it.

The scientists are, indeed, observing something: "profound behavioural and physiological changes" and labeling it "Pain". Perhaps this is a standard usage in the field; but when most laymen hear "Pain" they think about the kind of anguish that people can feel. This is something entirely different and cannot be established by observation (certainly not today).

It's my understanding that our best theories about how brains work tell us that fish nervous systems are not capable of experiencing this human-like pain and these experiments do nothing to change that.

Gil,

Can you find one source suggesting these "scientists" don't think fish feel pain in the human sense?

Pain is a feeling isn't it? How can that be measured? Aren't feelings subjective? Don't we interpret physical sensations with our brains? Thus, how can an animal have the same experience we have? They don't have our brains so they can't experience it the way we do.

You mean quale (plural: qualia) not feeling (emotion).

But it's not that fish can't experience it the same way because they "don't have our brains" -- two humans with different brains (we all have different brains) can, according to our best theories, experience the same quale the same way. It's that you have to be concious in the first place to have them. Fish are thus no more candidates than rocks.

Well, these scientists didn't speak about their results describing how the fish felt (which is good from a scientism point of view). Those conclusions were drawn by the animal rights activists and, perhaps, the article author. The scientists only claimed to have observed responses to damaging stimuli.

There was a quote from another scientist that did explicitly distinguish these findings from feeling pain.

Dr Bruno Broughton, a fish biologist and NAA adviser, said: "I doubt that it will come as much of a shock to anglers to learn that fish have an elaborate system of sensory cells around their mouths...

"However, it is an entirely different matter to draw conclusions about the ability of fish to feel pain, a psychological experience for which they literally do not have the brains," he said.

He quoted from a study by Professor James Rose of the University of Wyoming, US, in which it was found fish did not possess the necessary and specific regions of the brain, the neocortex.

I find it somewhat ironic that Elliot and this post's author seem to have drawn conclusions about what theories these scientists hold about fish feeling pain based purely on the observation that they have published a paper describing physiological and behavioural responses to damaging stimuli, the fact that they use the word "pain" (which probably has an observable technical meaning in their field),
and the interpretations of laymen.

I know that they didn't claim these conclusions to be scientific, but they still suffer from the same supportability problems that are ascribed to others.

But, I agree that it is correct to criticize those who did explicitly draw grand conclusions about fish feeling pain in the human sense.

Gil,

Have you read any of the article besides the part you quoted, which is from a NAA (fisher ppl) adviser..? OK, i know you have, but stop studiously ignoring it.

What am I ignoring? Where does the scientist (Dr Sneddon) say something that implied the fish feel pain as humans do?

Was it this?:

Dr Sneddon said the team's work "fulfils the criteria for animal pain".

Maybe I'm wrong, but I interpreted "animal pain" to be a technical term for observable responses to damaging stimuli, not a psychological, emotional, interpretation.

All of the conclusions about how the pain is felt seemed to come from the animal rights people, the author, and apparently many of the readers of the article.

David,

I think it would be useful to speak of robots experiencing pain. It would help people grasp a model for controlling it's behavior, learning, etc. It would be good to build in sensors that detect destructive stimuli, and avoid the source in the future. Pain is what I'd call it.

I'm not sure what facts are useful to zoologists, but this scientist said:

"We believe our study is the first work with fish of the teleost family [those with bony skeletons], and the results may represent an evolutionary divergence between the teleost and elasmobranch lineages."

Which sounds to me like it proves useful (some animals have developed certain receptors and others haven't).

As for the impression that the reporter was left with as evidence; it's my experience that reporters often make mistakes like this, and worse. I'd be very surprised if this has never happened to you.

David,

:) I'm sure it wasn't your fault!

So why don't we blame the journalist, and the animal rights wackos, and give the scientists the benefit of the doubt?

I like scientists.

Ok, I don't know how many scientists are associated with that group and agree with its chief executive, but those who do are guilty.

In order to conclude that others feel conscious pain you must establish that they are conscious.
Which is impossible.

The only thing we can do is observe their actions and draw conclusions based on how their actions parallel our own in similar situations, and make the assumption that they have a similar experience.

This applies not only to fish.

This applies to humans.

How do I know that you feel pain?
Perhaps because you say so? What if you don't speak English? What if you are to young to speak? What if you have brain damage?
Because you flinch, or yell, or cry? Those could be just instinctive stimulus responses. In fact, when you say "that hurts" that could just be a complex conditioned response. Perhaps no one feels pain in the way I do except me. Or, from your point of view, except you. Maybe know one else is conscious. You can never prove that anyone else is conscious, only that they behave as though they were.
So your neighbor and sister are just as much candidates to feel pain as a rock is.
If a fish has a brain, and reacts to avoid certain stimuli, it is not an unreasonable assumption to conclude that they are likely to experience something similar to what we experience in the same situation.

In any case like this, just insert "severely mentally retarded human" in place of what ever animal with a primitive brain you are talking about, and see how your argument sounds.

The only reason this is even a matter to debate is because people don't want to feel guilty for eating other things which have the capacity to feel.
Humans are animals. Animals think and feel and experience. Either get over it, or become vegetarian. Stop lying to yourselves so you can feel more justified. You aren't better than everything else, you are just different.

There is a very important difference between killing for food and killing for fun. Killing for fun is sadistic and constitutes as "evil" in my book. Killing for food is a necessary part of the food chain.

It is our responsibility as Humans to keep the suffering of our food to the bare minimum, without compromising the natural order.

Kill it clean, kill it fast, and thank it for its life.
