I’m writing this on my mini laptop computer again, because even though I find the extra weight of carrying it mildly annoying at the end of the day, at least sometimes the irritation of trying to write using my stupid smartphone is worse.

Although, since those two versions of me exist at different times, it’s hard to weigh their degrees of perceived irritation against each other.  In the morning, if I’m using my thumbs to try to type on a diminutive screen in a fashion that could be easily predicted to lead to some manner of repetitive stress injury, its all too natural for the “me” of that moment to hate the “me” of the previous evening who elected not to bring the laptop computer back with him.

But the “me” of the evening, when faced with the minor extra effort of the mini laptop, can feel very much overwhelmed and exhausted and think that the “me” of the following morning won’t find the process of writing using the smartphone particularly difficult.

The human consciousness clearly doesn’t have one, singular, constant terminal drive or goal as an imagined artificial general intelligence might.  I suppose one might think that the drive “to stay alive” would count as an ironically designated terminal goal, but that’s clearly not an accurate interpretation of the situation.

Not only are some people quite self-destructive and even actively suicidal—which you might credibly dismiss as dysfunction, not the lack of a dedicated system, though I think that would be imprecise—but there’s no good way to think that such a specific drive could evolve.  Evolution is blind to “death” as a concept or force, except as a failure, an accident, a lack, whatever you want to call it.

Before humans, as far as we can tell, no creature on Earth had a concept of “death” as the cessation of the biological processes of an individual organism.  Instead, there are proxies, such as the drive to avoid pain, and the related strong sensation of fear relating to danger and so on.

Similarly, there is no drive “to reproduce” in human (or other animal) minds.  Teens going through puberty don’t start feeling the literal desire to replicate their DNA in other bodies.  Instead, proxies for reproduction evolved, urges and drives that tended to lead to increased chances of reproduction, such as dominance hierarchy drives and displays in social primates such as humans, sexual attraction, and—of course—the pleasure of sex itself, with the reward-based drive to have it as often as feasible (with other inputs adjusting the strength of that drive and causing it to manifest differently in the two biological sexes and at different times and places).

The human brain—like probably all the other adequately complex brains on Earth—is a mélange of modules, with varying drives and processes that have evolved in parallel and sometimes independently, and also developed ways of interacting with each other.  Of course, at the root are the automatic drives that are all but undeniable—the respiratory drive, the thermoregulation drive, and so on.

There are even drives that are neurological in a broad sense, but that are so fundamental that they cannot be interdicted by the rest of the nervous system, only adjusted—I’m thinking here mainly of the heartbeat, the driver of which is in the sino-atrial* node and the Purkinje system of the heart, which is sort of a cross between muscle and nerve tissue.

The upshot is, if you ever feel that you’re “of two minds” on some particular subject, you’re probably not just speaking metaphorically, whether you know it or not.  Your final actions are produced by what I see as the final vector sum (and it can be quite small in the end or it can be huge in magnitude and surprising in direction) of all the drives or “pressures” in the brain that have any effect on decisions about behavior.  Then the action caused by the final behavior feeds back on the system**, changing the lengths and directions of some (perhaps sometimes all) of the contributing vectors, causing changes in the inputs and thus changes in the final vector sum of behavior.  Lather, rinse, repeat as needed, ad nauseam if not actually ad infinitum.

Please don’t imagine this as the sum of physical vectors in real spacetime.  The number of possible dimensions of such mental/neurological vectors is huge.  For all I know, there might even be spinors and tensors and matrices involved, but I don’t think those are necessary for my vague model.  “Simple” higher dimensional vectors probably do the trick.

What a curious set of things about which to write that was!  I had originally intended to start this post with some version of The Simpsons’ “Hi, everybody!”  “Hi, Dr. Nick!” exchanges, perhaps then noting that I could change “Dr. Nick” to “Dr. Robert” and thus reference both The Simpsons and the Beatles at the same time.

But then I might have noted that, although the Beatles song is so titled, “Dr. Robert” is not the way anyone has ever referred to me in actual practice.  It would be, honestly, a little weird for someone to refer to their physician as, for instance, “Dr. Joe” or “Dr. Judy” or whatever, certainly in our culture.

Mind you, there was that tendency for a while (it may still be prevalent) to have kids speak to adults such as teachers and daycare workers and people of that sort using their “title” and then their “given name”, such as “Miss Barbara” or “Mister Jimmy”.  I have always thought that was weird.  I mean, just imagine someone trying to address a certain prominent fictional character as “Dr. Hannibal”.

Alas, that all ended up being a discussion not worth having, except as an afterthought.  Though it’s debatable whether any discussion at all is actually worth having—including the discussion about whether any discussion is worth having.

You all can discuss that if you want; feel free to use the comments below, and to share this post to your social media platforms or what have you.  When you do discuss it, remember to define your terms ahead of time, and stick to them rigorously—i.e., the meaning of “discussion”, and of “worth”, and so on—so that you decrease your chances of getting involved in semantic games and misunderstandings and sophistry.

Whatever you choose to do, please try to have a good day.

*The “sino* in that term relates to its location in what’s called the sinus of the heart, and the “i” in it is a long “i”; it has nothing to do with China, though an identical prefix is sometimes used to mean “related to China”, but in this case with a sort of short “i” sound…or, really, a long “e” sound.

**And there are surely numerous other feedback loops all along the way affecting many, or perhaps all, of the vectors.
