To briefly state what I'm in, I believe that all theoretical accounts of reality (including materialism, physicalism and even religions) are attempts to make sense, to summarize shared experimental events.
In this sense, theories draw predictive laws that are solely made of buoys that point to other buoys in a dense fog. Buoys are composed by facts and their attached meanings. In other words, we do not make maps about reality (as people normally believe), all we do (and can hope to do) is describing the previously mentioned shared experimental events in a fairly orderly way.
What this means, in the context of present discussion, is that we all live in a closed phenomenal world, it is from this PW that we project stuff like "matter" and "minds" (to name the two central concepts involved constantly in this thread).
Now, do not confuse this with idealism, there is something "outside" the PW, we can deduce the existence of other PW's because language is a learned process, and we can deduce that the cause of our PW's are certain regularities, that we can call "reality beyond us".
What I don't believe is that we can create theoretical models that allows us to "see" that reality without us... a perspective from nowhere if you want. All our theories are necessarily anthropocentric and have the purpose of dealing with our PW in an orderly way, nothing more... No matter how hard we try to believe otherwise, our models deal with us, not with any projected "real reality".
