Yes, I understood that, but my question was about why you wrote:

With regard to support, we explained and gave examples but, briefly, just to illustrate again, here is a quote from where recursive justification hits bottom

So, apparently, what was illustrated was that Eliezer was not a good and faithful disciple of Popper when he wrote that. I'm a bit surprised you thought that needed illustration.

ETA: Or maybe you meant that your ability to dredge up that quote illustrates that you have been paying attention to whether and why LesWrongers believe support is possible. Yeah, that makes more sense, is more charitable, and is the interpretation I'll go with.

Ok, with that out of the way, I will respond to your long great-grandfather comment (above) directly.
