Enright examines the concepts of rationality and irrationality as he describes the reasoning processes that should underlie the core tasks that lawyers perform. These reasoning processes should ensure that each task is done as effectively and efficiently as human endeavor can make it.

Enright focuses on the core tasks with law from organizing an individual legal rule by dividing it into its elements and consequences to making, interpreting, and using law.

Enright explains the major structure that legal writing should use and highlights other topics such as writing with style, identifying the likely or intended readers, assessing their likely level of knowledge and understanding and then addressing the text to the level that is best for them; and understanding how best to approach and organize writing effectively.
