What this model assumes is a linear progression, but the mechanism actually described is cyclical. Cycles of expansion and consolidation.

We think of time as the present moving past to future, though the reality is that change turns future to past. Tomorrow becomes yesterday, because the earth turns.

There is no literal dimension of time, because the past is consumed by the present. Cause becomes effect. Time is frequency, events are amplitude.

We are mobile organisms, so our experience is a sequence of perceptions, which we constantly sort and order, in order to navigate, yet the reality is more thermodynamic cycles. Yesterday doesn't cause today, the sun shining on this spinning planet creates this cycle of days and nights. It is just that we try applying some larger, linear narrative to our experiences, to organize them towards collective goals, giving society some degree of cohesion.

Yet we are always going to be expanding out from present circumstances, which naturally creates a diversity of directions. Rather than accepting this as a necessary part of the dynamic, our social and political intentions keep trying to sustain a more monocultural narrative, continuing to do so, until the resulting pressures create irreconcilable tensions.

So the current major flaw in human evolution is escaping this useful tool of narrative, that has come to define us.

We do tend to turn the most useful tools, from money, to technology, into Gods. It is part of that cycle of expansion and consolidation, as the medium becomes the messge, then has to break down, in order for the process to continue.

The spiritual absolute is not an ideal of wisdom and judgement, from which we fell, but the essence of sentience, from which we rise. That we are aware, than the details of which we are aware.
