I am not sure. Do you mean what can we conclude that is just as certain?
No, I think I meant the above.
So for example, rather than start to lean towards anything resembling the idealism end of the spectrum, just because we mistake the certainty of experience for truth about the world and end up according subjectivity more importance than it may deserve, we should perhaps more humbly take the line that the reality of the universe probably trumps our puny and oh-so-recently evolved subjectivity, even if we must, it seems, perceive it via that subjectivity. Depose certainty from its vanity throne, in other words. Lean more towards realism than idealism, even if it means accepting our own relative insignificance, and quite possibly powerlessness, though we don't necessarily need to get into free will, but it seems to me to lurk nearby when we give primacy of importance to our mental experiences and capacities.
I am not certain of any of this, by the way.
It's just my tuppenceworth. I don't have a set or certain phiosophical stance, I don't think, though I do have leanings.
