Well, now, reading further along, I see I have a different notion of "ideology" than the one being tacitly used here. The idea here seems to be something like world-view, or at least such a view on aspects of a topic, such as the environment or politics or religion. Such a thing is unavoidable and, in fact, useful to help our approach to things be reasonably efficient.
To me, an "ideology" is a closed system--not just a set of beliefs but also a set of rules on how to think (or avoid thinking) about these beliefs (such as "consult scripture"). As such I don't recommend it and think ideologies only serve to limit one's ability to think.
Of course the scientific method might fit into such a definition--as it would if anyone ever finds a way to successfully describe what the scientific method really is.
