I certainly agree an objective perspective is an oxymoron, as knowledge is a function of framing. Context.

Though our tendency to view ourselves as noble and above the common life forms does tend to get extremely egocentric, narcissistic, self centered and self indulgent, when it loses the larger context. To the extent we are an expression of the universe, our goal should be more clarity of vision, than self indulgence.

As for wilderness, the jungle within does seem to take over all too frequently, so if we were more cognizant of the dynamics driving life and don't just ignore the basics, under the assumption we are above it, or at least beat the crap out of anything that might question our self assigned prerogatives, we might better understand that context that creates us.

As for life and meaning, my take is life is like a sentence. The end is just punctuation. What matters is how well you tie the rest of the story together. That we understand, feed and improve the networks connecting our nodes.

As for culture, how much of it is the social control necessary for large numbers of people to function together? Yet that can be both good and bad, if the group is itself more delusional, than connected to the even larger context.

The advantage of honesty, integrity, truthfulness in politics, is it keeps the group connected to the larger reality, so those enormous reality checks don't come along when the situation gets too far down the rabbit hole.

I don't think its really the delusions that are necessary, so much as it is being part of the larger whole and that does involve biases. Subjectivity.
