Aubrey de Grey Discussion, 25

I discussed epistemology and cryonics with Aubrey de Grey via email. Click here to find the rest of the discussion.

Aubrey did not reply further.

Note my last email to him began by saying:
If you want to stop talking, or adjust the terms of the conversation (e.g. change the one message at a time back and forth style), please say so directly because silence is ambiguous.
He answered this with silence.

I think that's pretty unreasonable.

I don't really want to write comments on the content of the conversation. It should speak for itself. (And in a fair way with back-and-forth discussion, rather than just me talking.)

But I did want to comment briefly on attitude to discussion.

You can read some of my thoughts on this topic in my Paths Forward essay. I think Aubrey is blocking discussion and preventing there from being paths forward. If he's mistaken, and it's a big deal, how will he find out when he simply leaves various criticisms unresolved and unanswered? If some of the epistemology he doesn't know is true and important, how will he ever find that out while not understanding it, not asking enough questions to understand it, and not having a refutation of it (by himself or anyone else)?

I think it's very important to address rival ideas. Either personally or by outsourcing – it's fine to use someone else's writing in place of your own, as long as you take personal responsibility for its correctness, as if it was your own. If a criticism of your position is not addressed by anyone (in public writing that's exposed to public criticism, comments, question-asking, discussion, etc), then it really ought to be addressed not ignored. Aubrey neither addresses various Popperian ideas (such as the refutation of justificationism), nor does he know of any writing by anyone else which addresses it. Yet he rejects it and stops pursuing it, without having any answer to it. This is not symmetric. The Popperian ideas I'm advocating are exposed to public criticism but are not currently refuted by anything. My ideas meet all challenges; Aubrey's don't; and Aubrey stopped discussing, leaving it like that without changing his mind.
