Aubrey de Grey Discussion, 23

I discussed epistemology and cryonics with Aubrey de Grey via email. Click here to find the rest of the discussion. Yellow quotes are from Aubrey de Grey, with permission. Bluegreen is me, red is other.
Elliot, you seem to be missing a very fundamental point here, namely: you seem to be working from the assumption that it’s my job to refute your position to your satisfaction. That is no more my job than it is yours to refute mine to my satisfaction.
If you care about reason, that requires dealing with criticism, to resolution. Reason requires criticisms must not be ignored, they have to be addressed (not by you personally. there must be answers you endorse, whoever writes them). This is crucial to reason so that you don't continue with bad ideas indefinitely even though better ones are known. It allows error correction instead of entrenching errors.

It is your right and privilege to live a different lifestyle than this. But then you wouldn't be a rational intellectual.
If you think that Alcor’s or CI's refutations of concerns about cryonics (the ones you’ve definitely already found, because they are in their FAQs) are less compelling than mine about SENS, you’re entitled to your opinion, but my sincere opinion is that they are every bit as compelling. I put it to you that the evaluation of how compelling an argument is is an EXTREMELY subjective thing, both to you and to me, arising essentially from how immediately a refuttion of it comes to mind. So, it is hopeless to try to agree whether this or that argument is more compelling than the other argument: each of us must make his own judgement on that, and then act on that judgement in the indicated way - by seeking more information, or by accepting a particular conclusion a likely enough to be right that further investigation is not a priority.
I don't know why you're speaking to me at all when you hold the irrationalist position that reaching agreement in truth-seeking discussion is hopeless. (I also don't know why you are sufficiently satisfied with irrationalism that you are unwilling to read the books refuting it and offering a better way.)
Again I repeat my bottom line: you have not given me the slightest reason to believe that people’s failure to adhere to CR (or to Elliotism) is appreciably slowing the progress of science and technology.
I gave you examples and explanations, which you largely didn't reply to. Then you state I gave you no reason. That's unreasonable on your part.
Maybe I can explain what kind of reason I would accept as valid evidence for that. Arguably, when quantum theory and relativity supplanted classical physics, they did so by taking seriously the incompatibility between wave-theoretic and particle-theoretic descriptions of light, and such like, which had been basically swept under the carpet for ages. My impression is that that isn’t actually an item of evidence for your position, because (a) it was a long time ago, when many fewer people were any good at science; (b) it hadn’t really been all that swept under the carpet - it was just that no one had come up with a resolution; and (c) even to the extent that it had been, the key point is that there was clear data that needed to BE so swept, whereas in the case of Copenhagen versus Everett (which I’m not sure is the same as Schrödinger versus Heisenberg, but I don’t think that matters for present purposes) there is no such data, since both theories make the same predictions. If I’m wrong, and the lack of a widespread adoption of a CR-like method of reasoning back then seems likely to have substantially delayed the arrival of modern physics, persuade me.
I have tried to persuade you (in a way in which I could find out I'm mistaken, too), but you are taking steps to prevent persuasion. I cannot persuade you unilaterally. What you have done includes:

- Not replying to many points and questions.

- Not giving appropriate feedback on initial statements so we can iterate to the point of you understanding what I'm saying. Miscommunication and misunderstanding are to be expected and there has to be iteration of an error-correcting process for effective communication of ideas. (Communication being necessary to me persuading you.)

- Not being willing to read things, study issues, put enough effort into learning the topics.

A specific detail: I can't reasonably be expected to persuade you about the history of science first, as you propose. What needs to happen first is you understand what is a CR-like method of reasoning, so you can accurately evaluate which scientists did that and which didn't. But you don't want to read the texts explaining what is a CR-like method of reasoning, or ask the questions to understand it. You aren't finding out from existing material or from a heavy back-and-forth process adequate to cover a large topic.
Or take another example from the past. If you’re right that science is so slowed by this, how can it be so hard to identify an example (one that isn’t far more parsimoniously explained by sociological considerations such as I outlined in my last email)?
Lots of the sociological considerations are explained by the philosophical issues I'm talking about. Because you don't know what CR is, you can't tell what is a consequence of CR or non-CR.

We have, for example, an educational theory. Where does short-term thinking, bias, egos, etc come from? Significantly, from bad educational practices. Education is fairly directly an epistemology issue and CR offers some better ideas about what educational techniques work or not.

Regarding statistics, yes scientists believe they should be done right, and sometimes there are time and money issues. But lots of people don't know what doing them right means. There are philosophical misconceptions about how to use statistics correctly which would be problems even with more time and money. (An example is the inductivist misconception that correlations hint at causation, which isn't a funding issue.)

The underlying problem is you don't understand where I'm coming from and what the world would look like if I'm right. That can't be settled by looking at examples. I gave you initial statements of Elliotism. The rational way to proceed is to iterate on that (you give feedback, ask questions, I reply, etc, understanding is iteratively created) in order to understand what I'm saying.
And remember, what I really mean here is not “science” in the DD sense, i.e. the improved “understanding” (whatever that is) of nature, but technology, i.e. the practical application of science. Computers today rely absolutely on the fact that we no longer adhere to classical physics, but they rely not at all on the fact that most people work with Copenhagen rather than Everett. The passage you quote from BoI totally doesn’t help, because it stops at “understanding”, “knowledge”, “explanations” etc, which in my book are simply smoke and mirrors until and unless they translate into practical consequences for technology. Not even implemented technology - technological proposals, like SENS, would be fine.
You have an anti-philsophical outlook and don't understand the perspective of DD, me, Popper, etc. If you want to understand and address such matters, there are ways you can, which we could focus on. I've tried to indicate how that can happen, e.g. with iterative discussion of how CR works. If you'd rather simply leave critics unanswered, just tell me you don't want to talk.
I read FoR, but I don’t think I ever read BoI. Perhaps part of why is that I found FoR to be fatally flawed on about page 4, as I think I mentioned earlier. DD is a great thinker, whom I hugely admire, but that doesn’t mean I think all his thinking is correct or relevant to my own priorities. And you haven’t given me any new motivation to read BoI.
I don't think you mentioned that. And I just searched the discussion and I'm not finding it.

If you would say your criticism of FoR, that'd be great. When people share criticisms in public, then progress can be made. I know DD wrote the book partly in hopes of receiving such criticism so human knowledge could advance. But you and many others with similar methods withhold criticism and dodge lots of discussion and then human knowledge creation is slowed.

Sharing your FoR criticism could help advance our discussion, too. It's topical and I've been trying to get direct criticisms from you. If you tell me what is unacceptable to you, then I could address it or concede. And if I address ALL issues you have with my view, that's how persuasion would happen. Since you already accepted your view has flaws, if you had NO objections you'd accept mine.

If you're right about FoR being flawed, you have an important insight that others could learn from. If you're mistaken, by sharing your criticism you would expose it to criticism and you could learn about your error from others. If you'd prefer to retreat from rational discussion instead, that is your choice.
