That response surprised me o:
I don't think that's true at all. If someone taught you how our solar system and our sun was formed following the big bang, would that not be considered knowledge? I doubt that understanding and knowledge is mutually exclusive because you would now know about the formation of stars and hydrogen fusing from being pulled together by gravity - allowing life to be possible here. Doesn't any knowledge gained require you to gain greater understanding?
Knowing about doesn't strike me as knowledge. Perhaps it is semantical, but given that I've experienced what I see as knowledge, I don't think it's just words. My experience with knowledge was there was zero doubt, and it permeated my being.
What you are talking to, is 'best educated guess' where doubt is almost seen as a great thing. You happened to choose something that truly no one knows and yet, unless I can provide evidence otherwise, then it passes for 'knowledge about.' Yet, even with very obvious, observable scientific 'fact,' (as in experiment could be done to day, with me present) I still see it as educated guess, and still see doubt as being something that is considered great to hold, though a bit ridiculous if it's more than a smidgeon.
To elaborate, in a way I'm comfortable doing, you are speaking to scientific theory which clearly passes as 'fact' and is based on sense of knowing. To me, that is misusing the word, but I would say I'm likely to misuse the word in that way (if discussing science with anyone). Yet, I'm also one who does consistently point out that science (of the physical kind) is ultimately based on faith. Based on faith in (physical) self, to put it simply. Faith in this case being the primary dictionary definition of 'trust, or confidence in,' and applying that to both intellectual understanding / ability to rationalize, plus faith in sensory perception.
All that works, and so I see no issue (honestly) with referencing it as faith. But to the point I'm bringing up, it is debatable if there is any such requirement to hold that version of knowledge to gain greater understanding. Because of the fundamental faith aspect that is indoctrinated into us (regarding our physical selves in an allegedly physical world), then it is challenging to argue otherwise. Not impossible, but challenging.
And part of the debate would be, for me, discovering the why, even if fellow humans/scientist types don't see the purpose. If going to tell me how human twins can be conjoined and what the process entails to form that, cool. But, I'm still wondering why and as I started this whole tangent off with, I don't see that occurring, which tells me that it's likely no one really actually knows, er, understands. I'm thinking many don't care, or don't see reason why it matters. Or perhaps I mean, how it matters.
