In my spare day off yesterday I watched a much anticipated debate between Ken Ham and Bill Nye over the feasibility of the so called “Creation” explanation for the origins of our universe. I have no desire to try and argue my side of the argument one way or another, and as poor a debater as I think Ken Ham is, he did bring up a point that I found at least mildly entertaining to ponder. The main backbone of his argument, and the idea that he claims keeps the creationist view point a valid one, is that there are two different kinds of science that we practice: observational science and historical science. Observational science consists of conducting current experiments and developing technologies that rely on the laws of science as we know them today. Historical Science on the other hand makes the assumption that the laws of the science have always been what they have today, and as a result we can run experiments and analyze data to interpret what the history of origins is. Mr. Ham claims that due to our lack of personal experience from those times we can’t actually prove anything. That logic isn’t really philosophically sound, and there are many reasons why it’s reasonable to assume there are underlying laws to our natural world, but if anything this did get me thinking about to what extent our understanding of science is belief based.
Now I’d like to just point out that I in fact have a deep love for the sciences, and it’s pursuit, and hope one day to pursue a deep career in them, but honestly I’d be kidding myself if I believed the scientific method was a perfect approach to answering all our questions and solving all our problems. I mean, I suppose were it done perfectly maybe it would be, but the point I’d like to make here is that there’s a lot more subjectivity and wiggle room in science than I believe the scientific society wants to admit. I don’t mean per se that scientific facts can be interpreted differently by different people (Although when you get into things like quantum physics an astute philosopher might be able to make a case), I mean that there is a certain amount of subjectivity inherent to our interpretations and assumptions of the raw scientific data. Everyone knows of all the various assumptions about the nature of our universe: The Earth is flat, the universe rotates around us, our thoughts come from our heart and heads are full of pus, etc.. The list goes on and on. Now many of those ideas were simply the result of a naive belief that we had enough information to make a judgement when we in fact did not. In our modern context we like to look back at those prior judgements an scoff, and I think it would be genuinely fair to say that we’ve much honed the practice and gotten better at accurately interpreting scientific data. That being said, I think that maybe we kid ourselves about the extent to which we can really say emphatically what we know for sure and don’t.
I don’t write this piece with the intention of trying to revolutionize the way we think about science, it would be trite to assume I could argue such a thing, but even if you think about the very way in which science classes are held. In a traditional science course we progress through a number of different chapters learning various different ideas and mechanisms. All of it is presented to us as pure fact. I absolutely don’t doubt that most everything we learn in introductory courses is probably the way it really works. By this long I think it’s safe to think that much of the basis for science would have been disproven if we interpreted it incorrectly. But the idea that maybe we don’t have the full picture yet, I would argue is the case across the board. Consider the case of evolution. Most any High School Freshman who’s taken a biology course could tell you that it’s the way life changes on our planet, and what the basic ideas behind Natural Selection are. Darwin and the whole nine yards. Now to most people (creationist excluded I suppose) this would suffice as an adequate explanation. But what if I told you that in all honesty evolutionary biologists still don’t have a complete picture of what natural selection is? To prove my point I’ll cite the example of Edward Wilson and his Multilevel Selection Theory. To summarize there had been a long held belief that selection of animals who practice social tendencies happened at the gene level. I.e. there were genes coding for certain social behaviors, and the best genes would win out. This was known as Kin Selection. Multilevel Selection theory argues that instead of at the gene level the selection happens at a combination of groups competing and the individuals within the group. It’s a subtle idea, I know, and I’m sure it seems like I just wanted to show you how awesomely knowledgeable I am, but there’s a better point here, hidden in the history behind this discover. In 2010 Wilson (One of the most famous biologists ever) presented a paper to Nature Magazine that he claimed presented a compelling argument for Multilevel based off of mathematical models he and other Harvard researchers had composed. In other words Wilson and associates claimed they could refute an old theory based on pure math. In science that’s a pretty gutsy claim, math is pretty highly regarded as far as proving stuff goes. But after it’s publication there was a tremendous uproar in the evolutionary biology field. Many hundreds of biologists from across the country responded by co-authoring a new article articulating all the various ways in which Wilson and his team made mistakes. Really it’s quite an impressive thing to see. Yet there are still many who support Wilson and his evidence. In other words based on how different people interpret the same scientific data and glean opposite results from it. In reality this is how all science works, and our “facts” are those things we’ve mostly agreed upon more than disagreed upon. In my eyes the biggest difference here between what we call science and what we call history is that most scientific pursuit exists as a possibility apart from time, whereas history by nature is stringent upon how well we can record certain instances in time. The interpretation of data is mostly the same, and the subjective aspect is still there even in science.
