I just finished writing a post and now I’m writing another one, what madness is this? I’m writing this as kind of a very-very-extended footnote to that post, since I couldn’t figure out how to write actual footnotes in the WordPress editor.
Specifically, I want to explain briefly the way I used the word spandrel in that post, since it is not a common usage, and may in fact be a usage I simply made up. I like it.
Originally, a spandrel was an architectural term for the space between an arch and its enclosing frame. In more recent times it has been borrowed by biologists to mean a biological characteristic which evolved as the byproduct of some other adaptive characteristic, and so may not necessarily be adaptive itself.
In my previous post I borrowed it yet again, by referring to the idea of intrinsic value as “a spandrel of human cognitive architecture”. The spirit of the definition should hopefully now be obvious and follows the biological one fairly closely except in that I am referring to thoughts and cognitive architectures instead of genetics and evolution. You may even take my usage to be memetic spandrels (as opposed to the genetic spandrels of the biological definition) though that honestly feels a bit stretched.
The most confusing part of this whole thing is that there are fairly obvious ways in which intrinsic values can be adaptive in an evolutionary psychology sense. Let’s try this again.
Go read How An Algorithm Feels From Inside. That central node in the second neural network diagram, the “dangling unit”, is a spandrel of human cognitive architecture. Just as it feels like there’s a leftover question even when you know a falling tree made acoustic vibrations but not auditory experience, it feels like there’s a leftover thing-in-need-of-value even when all your instrumental values have been accounted for.
