Matthew Frederick in 101 Things I Learned in Architecture School (The MIT Press, 2007) after saying how to draw a line, also says that there are three levels of knowing:
-simplicity, is the world view of the child or uninformed adult, fully engaged in his own experience and happily unaware of what lies beneath the surface of immediate reality.
-complexity, characterizes the ordinary adult world view. It is characterized by an awareness of complex system in nature and society but an inability to discern clarifyng patterns and connection.
-informed simplicity, is an enlightened view of reality. It is founded upon an ability to dicern or create clarifying patterns within complex mixtures.
