The Intersubjective

The intersubjective is a fascinating concept which I first found here. I will describe how I think of the concept, but I encourage all readers to visit that page.

The objective and the subjective are ordinary notions of how to categorize the epistemology of claims. Claims like “vanilla ice cream is better than chocolate ice cream” or perhaps occasionally “the photograph depicts a white and gold dress” are understood to be claims about the relation between the psychology of an individual and things in the world. Subjective claims such as these can be false, like if I actually did like chocolate ice cream more than vanilla, but the truth or falsehood can only be ascertained by those with direct access to that individual’s psychology, i.e. only the claimant. Consequently, most people are content spending very little time figuring out the truth of subjective claims. Claims like “chocolate ice cream contains more antioxidants” or “there is a peak in the reflective spectrum of the dress at 483 nm,” on the other hand, are not claims about the relation between the psychology of an individual and things in the world, but rather about things in the world themselves, and so can be measured and reported directly.

The intersubjective adds a third category. It asserts an epistemological category characterized by relations among many separate psychologies and/or among many separate psychologies and things in the world. You can jump straight to the examples, or continue with a strong caveat to all of this that stems from the difference between epistemology and ontology.

Statistical Invariances and Hierarchical and Dimensional Variation

Look around you.

How many repeating things can you find? In my room, I can count several dozen individual blinds over the window, two windows, several dozen buttons on a remote control, several dozen keys on my keyboard, thousands of carpet threads, six guitar strings, several dozen books, four pillows, and a partridge in a pear tree [kidding]. Interestingly, if I had the right equipment, I could tell that all of these things are made from 10^bignumber electrons, quarks, and pions, though if I go back to using my eyes, I’m only interacting with these subatomic particles through photons. These subatomic particles make atoms and ions in exceedingly regular ways. These in turn make molecules in slightly more complicated ways. These molecules in turn make bulk materials in even more complicated ways (or sometimes the pattern jumps straight from atoms to bulk materials, as with most metals). And then these materials go to make all kinds of different things. We can also take a detour through biology, where the molecules, in breathtakingly complicated ways, make cells, which then make tissues, which make organs, which make bodies. So we have a world replete with all kinds of different things, the vast majority of which are not unique, isolated things but rather similar to other things.

Implicit v. Explicit Information

There is a paradox in physics that occupies itself with the arcane possibility that black holes destroy information. Basically, Hawking radiation from the surface of a black hole seems to be uncorrelated with the captured material inside which is evaporating away via that Hawking radiation, and so the state pre-evaporation is not recoverable even in principle. I don’t seek to elucidate the paradox in the slightest, except that the holographic principle seems to resolve it, but rather I’d like to copy and paste their definition of “information” for my term “implicit information.” Implicit information is information regarding the configuration of a [physical] system. I’m not satisfied with that definition, but I think it perhaps more useful to contrast it with “explicit information”: explicit information is information that is ready-to-use by an intelligent agent.
