Ancient Civilizations with Different Cultural Bases

When we think about the existence, ten or twenty thousand years ago, of an ancient civilization and ask what signs might be left behind, we imagine our own civilization. But there is no reason that an ancient civilization could not have been built around a very different cultural basis. In other words, in the pathway from hunter-gatherer tribes to city-dwelling, tool-using, more civilized ancestors, there may have been a fork in the road. We went one way to get to where we are now, and they went another way. The possibilities need to be explored, or else we will just be out looking for signs of our own type of civilization ten thousand years before but extinct, and miss the signs of a different type of civilization, with knowledge and capabilities similar to our own, but with a different set of foundational rules.

One thing that must be the same is the science. Once a civilization has realized the periodic chart of elements, there are no more elements to be found. The exact same periodic chart will appear, given time, in all civilizations. The same holds for the laws of nature. Newton's laws would not have been named the same in ancient civilizations, but the mathematics which describes them would be the same. Telescopes are the tool of choice for observing the planets and galaxy, and optics is optics in any civilization. Combustion makes heat, which can be turned into motive power, in any civilization. So, the science and the engineering it enables would be the same. A society might be rated as to how far along the line of scientific progress they have travelled. There is some variation possible here, as biology might go a bit slower and astronomy a bit faster in one society compared to another, but there is only so much science, and a civilization which lasts long enough gets it all figured out. We are a couple of centuries from 'asymptotic technology', the point were there are only some small details left unknown, but an ancient civilization might have had cities and science study for more centuries that we have had, and have reached the culmination.

If science and engineering are the same, what can be different? Perhaps nothing is different in civilizations which reach and pass 'asymptotic technology', and the main difference is where a civilization is on that route. This concept is called 'technological determinism' and says that technology is the driver for cultural changes, and when a society picks up some new chunk of scientific knowledge, it will inevitably be changed by it. That means that societies would converge to some final state, not too distinct.

So, we might rephrase the question and ask, where will technology take us, and assume the ancient civilization was there already. We don't know where technology will take us, but it is possible to make some guesses in this regard, as much of technology has been worked out already, and more is being done every year, showing us a direction.

Figuring out where our own society is headed is a fascinating activity, and has been done by many fiction writers, who usually don't have 'technological determinism' and 'asymptotic technology' in their vocabularies. This means they would be very lucky if they are correct, as the fundamental rules by which society develops, at least after the dawn of the scientific method, provide a great deal of information that makes a great deal of difference.

Perhaps we might just ask a more pertinent and relevant question: what would an ancient civilization be like if it left almost no records behind. The obvious answer is 'small.' If an ancient civilization existed, say fifteen thousand years ago, but had only, for example, a half million total population, it would be much more likely that there would be no evidence left behind that indicated they were here on Earth before we were. That might mean three small cities, which could easily have been wiped away by environmental factors.

Does advanced civilization mean giant population? In most science fiction, populations are large. Population has been growing exponentially for hundreds of years, so why would it not continue? The reason might be that an ancient civilization asked itself what population it wanted to have, and the population of that civilization was wise enough to adhere to the answer, and limit or reduce its population to whatever choice was made.

What possible basis could they have had for making some numerical choice as to their own population? Why not ten billion or ten thousand? What kind of reasoning could they have used to fix this target? In our society, population is determined by billions of choices, as each couple decides how many children to have. In an ancient civilization, the same might have been true, but the mode of decision-making could have been different. One factor that could have been in play was the resources on planet Earth. Ten billion people use them up a million times faster than ten thousand. In our society, few people talk about the concept of resource exhaustion or anything else in this subject area, and those who do mention it note that resources are finite and there must be some stopping point in growth, perhaps followed by decline.

One difference between our society and the ancient one could be that they had this discussion much earlier in the population growth curve, and never got up to the hundred million point. This would explain why there were so many easily accessible resources left here for us to find and exploit. If their population had maxed out at a quarter million, there could not have used up much resources by their demise, and therefore we do not see some ancient quarries or remnants of mine openings or spills of petroleum or anything else that would be a signature of a huge population, with a high standard of living but little care for resource conservation.

The next step is to ask, what would a small population do, if it anticipated some catastrophe in the near future, and wanted to leave something behind? Another question is, suppose they didn't care about leaving behind some monument, what might have lasted ten or twenty thousand years which they created and used, not for the purpose of communicating with some new civilization in the future, but just useful for their living or important for their art or whatever else they valued? Since the non-exhaustion of resources is an important clue as to the nature of their society, we can ask about what other features there would be that might have the same origin as this decision.

Of course, another question is, were they from Earth, but that one needs to be put off until later, although an alien colony might have the characteristics we have found to be likely, low population and minimal resource usage. That would mean a modification of the original premise of this blog, which was why we haven't seen any aliens to a whole host of other ones, such as why would an alien civilization form a colony on a planet that was prone to catastrophes?
