I don’t pretend to have a definite answer either. But regarding the criteria for determining rocks and concepts to exist independently, I think there’s still a difference.Beth said:The way we establish whether something exists independently of ourselves is through the consistency of observations by different human beings. That is, if an object was observed to have the same properties regardless of who observed it, then it can be assumed that that object has an existance independent of those humans who examined it. When the descriptions differ significantly from one person to another, such as for gods and ghosts, we don't feel as confident because the disparate observations alter what conclusions can drawn from them.
In general, the more people that independently observe something and the more those observations agree regarding the properties of that thing, the greater the confidence we have that the object exists separately from ourselves. Using that same criteria, it's reasonable to conclude numbers, such as pi, have an existance independent of the humans who examine them.
Learning, recognizing and observing are actions (verbs), in a similar fashion as conceptualizing. I don’t think the criteria are exactly the same here. We seem to have “extra-conceptual” evidence of rocks, which is to say: we can still be hit by something that we usually conceptualize as a rock (here the conceptualization is a further, different, action). We don’t have such “extra-conceptual” evidence for numbers. In order to observe them, we must first perform the action; every single time … we must always think and conceptualize. Moreover, we must learn to think in a particular way in order to perform the action.
We don’t have to create rocks in order to be hit by them. But it seems that we must conceptualize (i.e., create) in order to have, well… concepts. Thus it seems to me there’s at least an asymmetry between the criteria we user for determining that rocks exist vis-á-vis concepts existing (independently from our thinking).
