I'm sorry, I didn't understand your post. That second sentence doesn't seem to hang together. Could you expand please? And were you tending to agree with me or Dunn?
Science at its basic level is based on knowns and/or a model/formula to explain observations of unknowns based on knowns. With string theory (for everything) and gaia theory (for earth) and other models/formula, true scientist may have reached the limits of knowns. This seems to lead to a "politicalization" of models/formula to explain unknowns. Thus, the issue of global warming is as political as Iraq WMDs and the 70s issue of "does smoking cause cancer?".
