We refer to this in our work as "2 x 2 thinking". While some people come to this naturally, many do not. As with most capabilities in life, natural ability or inclination is a great advantage. However, I have seen the other thinker types, "either-or" rise to impressive heights of 2 x 2 after periods of struggle to control or resolve the unresolvable. My view is that the dialectical view is indeed learnable, but the path is neither direct nor simple, typically involving personal challenge and change.
