Does History Make More Sense Backwards Than Forwards? An interesting point of view but the way I see it, the world's technology is known to only a small segment of humanity, there maybe, at the most, only a few million (scientists, technologists, machinists, roboticists) of us who can, if forced to, rebuild the technological infrastructure from scratch and I haven't even mentioned those involved in the supply chain of raw materials; the rest, the majority, know next to nothing about technology. The chances are, if a global catastrophe does occur, those who survive will be technologically illiterate and hence the stone age scenario is a real possibility.
Anyway, what I really want to find out is a point in our history (culturally, socially, economically, technologically, scientifically, etc.), assuming that it exists, that can be taken to be a line of symmetry such that every point on one side of this line has an equivalent and indistinguishable point on the other side. Sudden events like asteroid impacts and nuclear holocausts are too quick for a real one-to-one symmetry by which I mean, the stone age was thousands of years ago in the past but the one that follows a quick-acting cataclysmic event will be just a few decades in the future; in short, asteroid impacts and nuclear holocausts bring about their effects suddenly instead of gradually like how it happened in the past.
Another point I want to mention is that our notion of progress maybe flawed. On what grounds do we come to the conclusion that stone age people were primitive and we're more advanced? Machines, medicine, lifespan, etc.? With such criteria, sure, the present is more advance than the past but if one looks at it in terms of harmony, equilibrium with one's environment, we get an F.
