In my view, science is out-of-bounds to theorize about meaning. That is the domain of theology and philosophy and is appropriate according to the rules of engagement of the forum, e.g. at home, in church, on Free Republic, in an eighth grade public classroom.
As I said before, my beef with science is that it should pitch methodological naturalism and instead only declare the axioms or postulates that are appropriate for a particular investigation.
I a sense, I beleive they have. Methodological naturalism declares a set of axioms that are appropriate for all investingations. The proposition at hand seems to be that biology should be exempt so that philosophical arguments can be entered against ToE.
