As noted in the section on linked lists, the implementations in the last two sections depends on us recognizing the associativity of addition. This recognition is an example of what I call insight into the nature of a problem. When we understand a problem well we can use our creativity to implement direct and elegant solutions. Creativity has its limits, though: some problems inherently resist understanding while still requiring solutions. In such cases it is desirable to have patterns and heuristics that allow us to muddle through despite our lack of insight.
