Well, we switched theories because quantum mechanics and oxygen had more explanatory power.
no - we “switched theories” for a dizzying array of reasons; but probably the most relevant of which is that QM seems more likely than newtonian mechanics
to be true.
that said, what do you think counts as “explanatory power”? QM leaves a great
many things unexplained that were explained by Newtonian mechanics - space and time, for example.

I want to emphasize that I do not think that simplicity is the only theoretical virtue.
maybe not, but it is determinative in your initial argument, which is basically “atheism and christianity are indistunguishable in terms of their possession of whatever theoretical virtues there are,
except for simplicity: atheism is simpler; therefore atheism is more likely to be true”.
but that is as may be: you have yet to explain why you believe that:
(A) a theory with
n-1 entities is simpler than a theory with
n entities; and
(B) why the (alleged) simplicity involved in having as few entities as possible is theoretically more important than some other kind of simplicity (e.g. mathematical simplicity; being simply understandable; having fewer constants, etc.).

Well, I’m not sure that solipsism has that much explanatory power.
how so? it explains
everything without positing more than
one actual entity: there are no ships or shoes, no sealing wax, neither cabbages nor kings; there are no atoms or fields or forces; there is just my mind and the thoughts it thinks. period.
where does my mind come from? the same place the atheist says the universe comes from.
what is left to be explained? certainly nothing like the bewildering array of things that, for instance, quantum mechanics and the standard model leave unexplained…
jbehan:
Besides, why should dismiss solipsism out of hand? Clearly, it is an unattractive and unintuitive theory, but that doesn’t mean it’s wrong.
ahh, and now we get down to it.
of course counterintuitiveness and inelegance do not
entail truth, but they
are considered to be indices of untruth by those (e.g. many mathematicians and physicists) who take them to be theoretical vices.
but of course, what really matters is
truth, not simplicity or elegance or usefulness or explanatory power or fit with other theory or any other ciriteria for model-selection. just
truth.
and the real question is whether simplicity, in your reasoning, is a sufficient indicator of the truth of your conclusion - namely that atheism is more likely to be true than theism.
and i would say that even if you had secured your notion of simplicity (and you most certainly haven’t), that simplicity is just not capable of doing the epistemological and logical work that you are asking it to do (which is basically pre-empt the need to look at actual
arguments for the (non-)existence of the christian god by saying something like “
whatever else is true about those arguments, they are arguing for a world that is more complicated than the alternative; which means that those arguments
must be wrong”.)

There are people I don’t love or find difficult to love. What justification can I have for acting nicely to them?
it’s the right thing to do. pretty simple…
