I don't understand this BAA.
I don't have to imagine myself in relation to an ant - I can stand beside it and it's
reality. Likewise for a skyscraper.
As for imagining the ant and the skyscraper - well, the ant is a lot smaller than me, and the skyscraper is a lot bigger, so I'll imagine myself in relation to, say, Ireland. I can do that because I know the geography, distances, times involved in travelling compared to my size.
Maybe I'm missing the point completely.

I think what he's getting at is the middle-world thing - though perhaps ant and skyscraper don't go far enough to make it clear. In scales beyond those in which we have evolved, the universe gets very strange. Take quantum mechanics or relativity. Day to day rationality just cant apply there. We can use high tech instrements to get data, and abstract mathematics to understand it, but we cant then apply this information to decisions about what we want to buy from the shops, despite the fact that it
does make a difference.
What is day to day rationality?
I mean the rationality people use on a day to day basis, as opposed to - well thought out rational judgements made with all the available evidence - or even a superrationality as you put it.
Also, you forgot to explain what our failure to 'imagine' what an atom looks like has to do with human rationality.
It's not about imagining it - it's the fact that we can't comprehend how every quantum event will will change our lives, so we can't take them into account when trying to make a decision, therefore, as BAA said, it is impossible to be completely rational.
For one, empirical data that shows that humans don't make rational judgements, are bad at statistical understanding and generally aren't built to do well in various games (like the reiterated prisoner's dilemma).
Ok good.

Now back on topic, for the limited rationality we are capable of, do you think that it, and kindness, loyalty, honesty etc. are intrinsic aspects of specific individuals, or is it more useful to think of them as temporary acts that we are all capable of?
