On an individual basis, or I suppose in a small process therapy group, the underlying values & beliefs could be brought, at least in part, to the surface & discussed.

We take so much of our foundational beliefs, without even noticing it, from our upbringing, social interactions & education. These foundational aspects are important to the stability of society but they are seldom examined in an objective way for their actual plausibility. These beliefs often persist when their function & usefulness has long passed.

On a larger scale, such beliefs gradually evolve often with great suffering & turmoil. Consider the transition of western cultures from Christianity & feudalism, to Capitalism, scientific inquiry, & triumphant technology, and now to recognition of life extinction on a mass scale & what to do about an 8,000,000,000 population. (Shades of Hegel's dialectic in all of this.)

Or for that matter, the Islamic belief system fighting for relevancy in the modern world of science, capitalism, democracy, religious freedom, value fluidity, & gender issues.
