And I can agree with some of that but the point is that he's still a scientist even if all of the above is true.

Funny how it's also provided us with dozens of candidate morphogens compatible with the Turing model, as in the proteins coded for by those gene families I cited earlier, along with data from the manipulation of the signalling pathways those genes operate within, and the experimental demonstration of reliable and repeatable changes in the development process arising from those signalling pathways.
It's not really "funny" at all, as that's to be expected. Something being "flawed' (if true) doesn't mean nothing valid can ever come of it. Sheldrake is arguing that it is flawed in a very specific way which relates to very specific questions. Why exactly did you think it would affect work relating to the Turing model or anything like that?
Calilasseia wrote:In the meantime, what does Sheldrake have in support of his "morphic fields" assertion? Sweet bugger all. So the idea that science can't answer some of the questions he's asking, is complete hooey in the case of morphogenesis, because the relevant questions were asked about this process
before Sheldrake was born, and a working model devised that has since been supported by large numbers of empirical tests.
But of course he has nothing because, if he was right, there couldn't possibly exist any scientific evidence for his claims because science is currently incapable of accounting for what he's describing.
You must see the circular flaw you keep running into here, right? Sheldrake is saying X is true but science can't see that it's true because it is flawed. You are saying that if X is true then where is his scientific evidence. Sheldrake is saying that X is true but science can't see that it's true because it is flawed. You are saying...
There are ways to argue that Sheldrake is wrong (obviously) but telling him to gather scientific evidence, of which he agrees cannot support his claims, is insane.

I don't understand the relevance.
Calilasseia wrote:Plus, if he erects an untestable assertion, it's not the fault of the scientific method that it's untestable.
Maybe so but we'd need to demonstrate that. We can't show that he's wrong simply by asking him to gather evidence from a methodology that he has deemed to currently be unsuitable. If the fault lies with his position, and not the current state of science, then we should show that.
Calilasseia wrote:Supernaturalists have been deploying this tactic deliberately for centuries, to try and protect their asserted magic men from scrutiny.
Perhaps but that's not relevant here as Sheldrake is doing the opposite, he's trying to set it up so that science can actually test the claims he's making.
Calilasseia wrote:If Sheldrake wants to be taken seriously, as I said before, he should get off his arse, and do what Stanley Prusiner did when he erected a controversial hypothesis. Prusiner didn't sit around whingeing because other scientists wanted evidence, he got off his arse and
found the evidence, which is why he's now admiring a nice shiny gold medal from those Swedish persons on his mantelpiece.
That's lovely but it's not relevant here given that Prusiner thought that his questions could be adequately answered with the current scientific methodology, whereas Sheldrake doesn't.
And to be clear here, whilst Sheldrake is arguing for a fairly radical reform, the idea that science should be questioned and has been forced to change in the past isn't at all controversial. There have been multiple occasions in the history of science where the methodology, or general atmosphere, of science has proved to be inadequate for answering particular questions and it has been changed. Nobody at the time argued that "if science was flawed then you need to present your scientific evidence of it being flawed" because that's a silly argument and simply shows that the person has failed to grasp the claim being made.
Sheldrake has presented some extreme views on what he thinks need to be changed and why he thinks it, and it would be interesting to see some arguments against them (because even stupid ideas can have great worthwhile rebuttals).
