Reflection: The Difference Between 'Illogical' and 'Not Logical'

Can everything be classified as either logical or illogical? I don't think so. I think a lot of people call behavior 'illogical' when it is merely 'not logical' -- and that there is actually a huge difference between those two things. So much of our experience, whether we're normal or not so normal, is not about logic at all -- it's about drives and impulses and changes in arousal level (perceived as either interest or fear).

Is motivation logical? Well, it's mitigated by logic -- hopefully-- but that's not the same as being driven by it. There's quite a bit of evidence of brain reward systems running on chemicals (ie dopamine) in kind of a 'ka-ching ka-ching' fashion. There's scientific evidence of reward system irregularities being implicated in various disorders. Is a person less logical because they fail to experience reward or motivation in the more typical ways?

Ah, and then there's the issue of drives. Just about everyone has heard the term 'drive' applied to things like sex, but there's also a drive toward monogamous/ faithfulness, supported by its own system of neuroeptides. (Some of thItalice early research on that came from studying prairie voles, and why it was that they formed pair bonds and nurtured their young for a long time when other related species didn't.)

Of course I've also written recently about the issue of sensory processing -- having the 'volume of the world' turned up unusually high or turned down unusually low. Ultimately... I think it's illogical to expect others' non-logical parts to operate the same as our own!

Reflection: A Response to Dr. Laura

My sister-in-law sent me a book by Laura Schlessinger, and I read the whole durn thing. Now I’ll concede Dr. Laura a few points: Yes, there are things one shouldn’t put up with from another human being; yes, there are wrong reasons to ’put up with’ things. And yes, one’s primary attachment should be to one’s babies. That said, I’ll spend the rest of this post arguing with Dr. Laura. She argues against “stupid attachment” -- attachment to flawed human beings who aren’t your little kids -- and then describes scenarios that don’t involve attachment at all. I remember an acquaintance, some years back, saying you were not attached to something if you were willing trade it for something else of greater or equal value. Boy, do I stand with him on that one! The I want somebody, I need somebody mentality is an example of dependency; it has nothing, but nothing, to do with attachment.

Now I wonder what Dr.Laura would say about the prairie voles. Prairie voles have been in the news much more often than the average rodent. It’s partly because of them that scientists know that monogamy is a drive, supported by its own neurochemical systems. There's a volume of research that goes back years: scientists wondered why this one species of vole was monogamous and nurtured its young for a long time, when other closely related species weren’t (and didn’t). What was different about this vole’s neurochemical systems -- and were some of those same systems at work in human beings ?

The short answer is yes. Those same systems are in place in people, though they don’t function identically. One of my all-time favorite movies is A Beautiful Mind. The woman in that story… well, there are different types of strength, but hers is the type of strength I can admire. Of course a Dr. Laura could argue that life isn’t the silver screen... and that an over attached person has only themselves to blame when their attachments cause pain. That’s a valid argument. But it’s not valid to equate over-attachment with dependency, or to suggest it’s an affliction of women who lack their own strength, their own self-worth, or their own voice. I think that often -- I’m not going to suggest always -- it's the people who don’t have strong attachment/monogamy drives themselves who most self-assuredly and vocally mistake attachment for weakness.
