Seems to me that you don't understand that dictum, because it's function certainly does call into question "past" knowledge...because what leads to the realization is just how tenuous even our most trustworthy sources of information are. So everything we think to be true at present is questionable whether we can call it knowledge, with ordinary skeptical challenges like Munchaussen's trilemma only being compounded by more recent skeptical insights like the existence of Gettier problems. The more we learn and challenge what we know, the more we realize that there isn't a single unimpeachable source to draw any knowledge from. Of course, I am not talking about ordinary truths like things that are immediately present to our perceptions but any attempt to make sense of such things. This goes doubly for moral questions, but its a challenge even for less judgment-laden issues.I'm well aware of the dictum that says the more we know the more that we realise that we don't know. But what we have learned in the first place should still be available. It's not like you're Homer and have to forget a bunch of stuff to learn something new. So what good is all that book learnin' if it means that you don't generate some opinions on matters such as objective morality?
Book learning, if we're reading books that challenge our perspective rather than simply shoring up our personal convictions, drives home the dependence we have on sources that can never be vetted to the point where we are fully informed without some questionable elements being adopted unknowingly. Especially when we come to appreciate just how deep deception and bias runs in the human psyche.
