Nonpareil
The Terrible Trivium
Since everything we experience is necessarily "framed" by the act of experiencing, it is tempting, and it is also quite possible, to more or less adequately explain the universe using models in which the act of experiencing is the origin of everything experienced.The most parsimonious and self-consistent of such models is solipsism, but that fails to explain the apparent similarities between our own and others' experiences. So the most popular models of that type end up including a unifying entity, a universal mind or first experiencer. The partial subordination of our individual experiences to the unifying entity's explains their similarities to one another.
Those models, which I'll loosely equate with mysticism, are almost perfect inversions of the materialistic one, to the point where in many ways they're almost equivalent and lead to some of the same destinations, including certain ideas about the nature and boundaries of the self and the meaning of death. This is generally unappreciated, in large part because most materialists haven't gone far enough in following up the logical implications of the materialist model. That's something I have to write an essay about soon, though it's looking like a monumental task.
I don't agree about the explanatory or satisfactory (or even coherent) nature of idealist models, but I'd be interested to read the essay regardless. Let me know if it's ever finished.
