My mind does work like that all the time, Iains. Not that I am claiming I never make mistakes, or there is anything particularly special about it: it is just my way of 'being in the world'. Just like a historian cannot walk through a town without subconsciously (or consciously) continually reflecting on why that building is there and not elsewhere, or when it came to be; or a geologist going through a landscape - they are habitually assessing the geology even if they are unaware of it. Or a good salesman seeing the openings and closes in any conversation they take part in. Or an artist. Or a poet.

Just my way of being happens to have formal logic rolling away in the background the whole time.
