Thought and Behavior
"Complexity is that sensation experienced
in the human mind when, in observing or considering a system, frustration
arises from lack of comprehension of what is being explored. While this
definition may be thought surprising, one of its notable attributes is that
it allows for the possibility that complexity may be reduced or even eliminated,
at least for some human beings, by a process called "learning".
