The conviction upon which much of my thinking has been based over the past decade, has included that human consciousness has developed, or evolved (to a plan), or transformed - and I mean actively developed, from inner (and ultimately divine) causes - through the modern era.
This is a metaphysical assumption; and so is the usual and opposite mainstream idea that human consciousness now in the West is the same consciousness as human beings everywhere else in the world, and at all points through history.
(Another fairly mainstream metaphysical assumption - of totalitarian modernity - is that there is no such thing as human consciousness, that it is some kind of misunderstanding, or maybe a temporary accident; or that the human can and should be "transcended" by something "better" - by adding or replacing-with computers, genetic manipulations, AI &c.)
Both the development of human consciousness and the universality of human consciousness are assumptions: metaphysical in nature.
Neither assumption is provable by any kind of evidence (because evidence depends on assumptions: the empirical depends on the metaphysical) - we can just point-out observations that are easily compatible, or not, with these assumptions.
But if one believes that consciousness has changed, one important consequence is that modern Western Man cannot go back, he/we cannot revert to an earlier stage or phase of civilization; since earlier stages were manifestations of a different consciousness.
For example to fit Modern Man (with his different consciousness) into a medieval European type of society, would be like hammering a square peg into a round hole.
Modern Man would need to be "made to fit" medieval structures and systems - they would not ever come naturally to him. In other words the need for hammering, represents some extremely different kind of social control and enforcement - which would mean that the resulting society was Not the same as in medieval Europe.
This would be because - at a fundamental level - Modern Man experiences the world differently, "processes" his perceptions differently, has a different and greater self-consciousness... And therefore responds differently to incentives and sanctions.
So, it is important to consider the validity of the - often unconscious and unexamined - assumption that "Men are functionally and essentially the same always and forever"; because if that is Not true but you believe it; then you will find yourself assuming possibilities that are actually impossible; and perhaps in trying to attain the impossible, you will be doing significant harm.
Furthermore; if God has indeed made things such that Men are different in different places and times, then it is reasonable to infer that God has a different destiny for different times and places.
...What is valid for one time and place may then be evil for another.
This is not proposing any kind of "relativism" - quite the opposite!
What I am advocating is to believe that there really is a divine destiny for places and times, for nations and eras; as well as for individual persons - and that it is our job to discover and live-by the divine destiny that applies to us, personally.
(And, insofar as it is relevant; to be aware that our divine destiny may not be identical with everybody else's!)
