geography

If you look at the map of the US it’s for the most part a box with clearly defined boundaries on all four sides. Canada is also a box but with only three sides, the top boundary line essentially does not exist. This is not a liability. Once understood it allows for great clarity of thought. It ultimately avoids the inherent claustrophobia of a completely four sided model. The Mediterranean Sea functioned in the same way to form thinking in the early archaic culture of the Greek islands in the Aegean.

The US is also situated mid way between the Far East and Europe and has benefitted from proximity to the former to produce great artists like Ad Reinhardt and Agnes Martin.
