Theory and Practice

I feel like I probably have at least one other blog post with the same title. Perhaps several. It's a pressing concern of mine: what's the relation between thinking about the world, and actually doing something in it?

I've been reading about diplomacy as of late, the history and reality of international cooperation. I'm thinking about possibly going into the foreign services at some point. But I've realized that in order to do that, I need to develop some very different mental habits from what I did in philosophy.

One key difference seems to come down to this: in practice, one needs to listen to all sides. In thinking about the world, though, sometimes there are sides that are just spouting bullshit. There always in fact exist multiple sides to a topic, but not all sides are equal. Just because conspiracy theorists exist does not mean that we should take their views seriously.

If everyone formed opinions purely rationally, then of course we should listen to everyone's opinion in formulating our own. But human beings do not always (or perhaps often) operate rationally (actually, I will revise that in a later post, but we'll work with that hypothesis for now). We (and I do mean "we") form opinions based on what makes us feel emotionally comfortable, on fear, on the basis that we have enough knowledge to form judgments for ourselves.

An opinion based on fear is not in itself a valid side in a rational discussion. One might have valid reasons for the position, but as soon as emotions get high, I have reason to suspect that the emotions were determinative in reaching the view. And I could be wrong; there always could be some truth to a person's position, just as it could be the case that we never landed on the moon, but there also comes a point where we admit that some people just spout nonsense.

I have no patience for climate change or evolution deniers. They fundamentally misunderstand basic terms and theories (like, for example, the word "theory"). Environmental scientists and biologists (you know, the people who actually know what they are talking about) are pretty settled on the basics. We can have a little (very little) debate over whether climate change is anthropogenic, and a lot of debate over what possibly could come of it (climate change doesn't mean that everything would change tremendously; it just means that it is a significant enough possibility to take seriously). But the fact that 1 out of 10,000 environmental scientists dissents, or that some physicist with no understanding of the specific subject matter (or, worse yet, your local doctor) doesn't form the same conclusions, is pretty much irrelevant. And the second an evolution-denier trots out the 2nd law of thermodynamics, the discussion is finished. I don't care how much education they have; they fail basic physics. (Not to mention the inanity of "missing link" objections, or the idea that the fossil record is even the primary evidence for evolution.) If a climate-change denier insists that climate-change is some new myth on top of global warming, or if they point to a cold day as evidence for their view or to a pleasant warm spells and 14th century English vineyards as evidence that global warming would in fact be good, they have removed themselves from having a valid opinion to contribute. They are misguided on so basic a level that they are not engaging the topic. They can be taught (a practical effort), but their opinion matters as little as a math student who claims that a theorem is wrong because it is “too abstract.” (To appease some members of my audience: claiming that a single warm day or season proves global warming, or being an atheist who claims that denying the Christian God is the same as denying Thor, is to be similarly clueless.)

So, as a philosopher or a scientist, the job is to judge. Not all opinions are rational or informed, and those that aren't can be culled. In trying to figure out the truth about politics, even, this can be the case (Scott Walker is a douchebag. The fact that there is "another side to the issue" doesn't mean that that side has a clue. And trickle-down economics just does not work.) But practically, standing around and telling people that they are clueless is in itself pretty clueless, if one's goal is to make things different. It's not enough to think true thoughts about the world. Things need to be done, and that requires compromise. Climate change is real; great, but you still have to work with the deniers who say that there is some vast left-wing conspiracy. You need to actually get things passed in legislature. You need to provide education that is approachable to them, not that pushes them away (this blog post, for example, is not a good example of such – but that wasn't my intent). Do you think racial profiling exists? Great, so do I – but for God's sake, don't present an oversimplified case which cuts out the actual details of why a shooting was considered to be self-defense. Doing so will only convince the deniers that you as a bleeding-heart liberal can only support your view by distorting evidence.

So that is the challenge: I have been trained to judge matters, to look into only the sides that have significant reasons. Doing this often puts me at odds with culture, which doles out such asinities as “everyone has an opinion,” as if the freshman knows as much as the seasoned economist. Democracy means that everyone has worth as a human being and that the government should be for the people. Understanding still has to be earned. But because I think that certain things are true about the world, I want to change the world for the better. Part of the problem as to why there are so many climate change deniers is that the scientists don't actually take the time to work better with media sources, to give the public an understanding of the issues involved. They abdicate the position of go-between because it's frustrating. There need to be more people bridging the gap between theory and practice, as difficult and as taxing to patience and to principles as that might appear to be.

Are Beliefs Practical?

Beliefs are slippery little buggers. On the one hand, they are tools for navigating life. We believe certain things so that we can get around in the world. We need some way of dealing with the complexities of reality. I believe that western medicine by and large works and that it works far and away better than the alternatives. Therefore, I go to doctors trained in Western medicine rather than homeopathy or Ayurveda.

The belief is a means to an end: namely, my getting better. If I didn't need to get better, why would I worry about different medical practices? We have finite lives. We can't spend all of our time trying to make sure that our believes are correct, so long as our lives are running well. If I pick a shoddy medical practice that works for me, even as a mere placebo, I still feel better. What's the harm?

Sometimes, the belief can even change the result. William James talks about a person who is about to jump across a chasm. If this person believes that they can make it, they will have a higher chance of doing so than the persons that doubts themselves and hesitates. So believing something simply because we want it to be true can sometimes make it true.

But beliefs aren't merely tools. Having a belief means that we take something to be actually true about the world already. I take it to be the case that most of my sicknesses are caused by microscopic bacteria, viruses, and so on. The world is not made up of either 4 or 5 elements. Theories based on balancing these elements are just plain false, despite occasionally producing useful results. I can't believe that balancing the fire and water in my body will heal me without also believing that this is actually how things are; the very idea that I could is just nonsense, though some people have astonishingly high skill at self-delusion which allows them to get around this logical nicety.

So how can we take something to be true about the world and not care about whether it is true? How can we believe something, but then be unwilling to put it to critical analysis and to search out whether it is true? But is this really a problem? Why not just take it all with a grain of salt? Use beliefs as tools only. Believing something becomes like watching a movie – we suspend disbelief rather than take the plot to be actually true. It's a story to guide our actions, but merely a story.

This helps with local events: both local in space (affecting me and those closest to me) and in time (short-term goals). Sure, if I follow the medical tip from some random second cousin and it makes me feel better, then it works for me. I don't have to believe anything more than that it has been personally useful. However, it is not clear that this approach deals effectively with broader issues, such as those affecting other groups or calling for short-term sacrifice for the sake of long-term gain.

Take climate change, for example. There does seem to be some truth to the matter as to what will happen in the future if we continue to live as we do. Either humans beings are actually causing climate change, or we are not. Either this will produce a wildly out-of-whack world, or it will not. Either changing emissions in certain ways will help us deal with the problem, or it will not. (There appears to be little actual evidence against the notion that (a) there has been climate change over the past century of alarming proportions, and (b) that it is in large part caused by human beings. However, there is still a lot of discussion over what that entails for the future.)

There is potentially a disaster coming up within a couple generations, and adjusting ourselves to meet it could result in short-term sacrifices. We cannot merely look at what is practical for ourselves here-and-now in our own country to decide what would be better overall in the longer-term. Even if we were to decide that large-scale changes would not need to be implemented, it would have nothing to do with the fact that such changes would be hard right now – it would have to do with our best scientific research telling us that climate change won't be mitigated by our efforts. People arguing from local practical concerns alone, such as loss of jobs and increase in price of goods, completely miss the point, regardless of what our best plan of action will be.

I do not pretend to have an answer to this problem; I merely point out that there is a problem which must be dealt with based on matters of truth beyond what is recognizably practical to us now. (I thought I would give religion a break for a blog post, so I went with science instead.) So beliefs about what are practical to me and those close to me for the short-term can be decided through purely practical means, with little regard to overall truth. But those beliefs are also only suited for these very particular circumstances. Change the context, and the validity of such practical beliefs also changes. So for more far-reaching goals, concern over truth and the theoretical value of beliefs becomes more important.

Politically, this is problematic. Democracy and a democratic voting system is based on people being able to know where their interests lie, and trusting that people overall are smart enough to figure this out on their own. And this might be well enough for locally practical beliefs, for those that guide people through their own day-to-day experience. But people also vote based on issues impacting their communities, their country, and even the world, and it is not at all clear that their experience is useful here; in fact, it might even cloud their judgment in such matters without proper education showing them the bigger picture (and taking a couple science classes hardly instills scientific literacy).
