Why do things make sense?

Things pretty much make sense. If they don’t we feel that there is a reason that they don’t. We laughingly make up goblins and poltergeist to explain how the keys came to be in the location in which they are finally found, but we, mostly, have an underlying belief that there are good, physical reasons why they ended up there.

Things appear to get a little murkier at the level of the quantum, the incredibly small, but even there, I believe that scientists are looking for an explanation of the behaviour of things, no matter how bizarre. One of the concepts that appears to have to be abandoned is that of every day causality, although scientists appear to be replacing that concept with a more probabilistic version of  the concept of causality. But I’m not going to go there, as quantum physics has to be spelled out in mathematics or explained inaccurately using analogies. I note that there is still discussion about what quantum physics means.

We strive for meaning when we consider why things happen. When a stone is dropped it accelerates towards the earth. This is observation. We also observe the way in which it accelerates and Sir Isaac Newton, who would have known from his mathematics the equation which governed this acceleration, had the genius to realise that the mutual attraction of the earth and the stone followed an inverse square law and, even more importantly, that this applied to any two objects which have mass in the entire universe.

So, that’s done. We know why stones fall and why the earth unmeasurably and unnoticeably jumps to meet it. It is all explained, or is it? Why should any two massy objects experience this attraction? Let’s call it ‘gravity’, shall we? How can we explain gravity?

Well, we could say that it is a consequence of the object having mass, or in other words, it is an intrinsic property of massy objects, which if you think about it, explains nothing, or we can talk about curvature of space, which is interesting, but again explains nothing.

Can you see where I am going with this? Every concept that we consider is either ‘just the way things are’ or requires explanation. Every explanation that we can think up either has to be taken as axiomatic or has to be explained further. Nevertheless most people act as if they believe that there is a logical explanation for things and  that things ultimately make sense.

It is possible that there is no logical explanation of things, and that the apparent relationships between things is an illusion. I once read a science fiction story where someone invented a time machine. Everywhere the machine stopped there was chaos, because there were no laws of nature and our little sliver of time was a mere statistical fluke. When they tried to return to the present they could not find it. This little story demonstrates that although we appear to live in a universe that is logical and there appears to be a structure to it, this may just be an illusion.

If we do live in a logical universe we not be able to access and understand the basis and structure of it. We may see things “through a glass darkly”. We may be like the inhabitants of Plato’s Cave. Everything we experience we experience through our senses, so our experience of the world is already second-hand and for many purposes we use tools and instruments to view the world around us. Also, our sense impressions are filtered, modified and processed by our brains in the process of experiencing something. We can take prescribed or non-prescribed drugs which alter our view of the world. So how can we know anything about the universe.

Alternatively there may be order to the universe. There may be ‘laws of nature’ and we may be slowly discovering them. I like the analogy of the blanket – a blanket is held between us and the universe but we are able to poke holes in it. Each hole reveals a metaphoric pixel of information about what lies behind the blanket. Over the years, decades, centuries and millennia we have poked an astronomical number of holes in the blanket, so we have a good idea of the shape of what lies behind it.

So why do things make sense? Is it because there is a structure to the universe that we are either discovering or fooling ourselves into believing that we are discovering, or is there no structure whatsoever and any beliefs that there are illusions. Maybe there’s another possibility. Maybe the universe does have the structure but it is an ‘ad hoc’ structure with no inherent logic to it all!

  1. I rarely leave comments, but after reading a ton of comments here Why
    do things make sense? | Me on the net. I do have
    a couple of questions for you if it’s allright.
    Could it be just me or does it give the impression like a few
    of the comments come across as if they are coming from brain dead individuals?

    😛 And, if you are writing at other sites, I would like to follow you.
    Would you make a list of every one of your shared pages like your Facebook page, twitter feed,
    or linkedin profile?
