First intersubjective, then internalised
Taking this further, rationality is a concept from the study of logic, which is itself an offshoot of epistemology. So we can analyse rationality using a lot of tools. Rationality refers to the idea that there are reasons for things consistent with the axioms underlying a particular system of logic.It's perhaps a bit different, but the word rational also dissolves when you look at the reality of people's lives, when you try and think about things from their perspective and their experiences. We all think things and do things on the basis of who we are, our experiences and the influences brought to bear on us. When it comes to things like voting, it is rarely irrational, there is always a reason or, perhaps, a rationale. Calling people stupid or irrational means you don't have to engage with them, who they are and what is going on in their life. Don't even have to think about the wider political economy. To be honest, I think that using 'stupid' as a reason to not engage with people or think about their lives has been going on on this thread. I don't say that (purely ) to provoke a further round of Urban's 'stupid war', I think it's an important point to make in itself.
In fact it seems feckin' obvious. When you get something like Brexit or the Dems failure to win even against someone like Trump, something is worthy of further thought. Something about the liberal order and the effects of neoliberalism and austerity. Stupid doesn't take you there.
When people refer to “rational”, though, they generally don’t specify their axioms. And normally, they implicitly mean economic logic, which are based on the set-theoretic axioms of choice. However, that is just one way of ordering data — one in which you can commensurate all goods as a common dominator in order to compare baskets of goods against each other.
There are three other ways of ordering data, which are mutually incomparable — nominal, ordinal and interval. These produce three other types of rationality. Nominal is where you can’t quantify and therefore no counting (or exchange) is possible. We generally think this way about bodily autonomy. Ordinal is where you can rank but not track items. This produces hierarchy. And interval allows us to track items like-for-like but not against each other. This produces the rationality of gift giving and favours for favours
If you try to use one rationality where another has cultural acceptance, you get confusion, anger and punishment. So trying to buy a body part with money is normally seen as morally wrong. Similarly, you don’t pay your friend for making you a meal. You can’t declare a hierarchy amongst your friends.
One of the tricks capitalism pulls is to privilege economic rationality over all other forms. But don’t fall for it. Other systems of logic are also valid! And depending on the context, maybe much more valid.
