What is legal obligation? This question has been the subject of debate for centuries. This book is part of a collection of short essays about the nature of citizen obedience. The text examines the relationship between manmade laws and obedience. The argument is that there is no inherence in legal obligation. Mother Nature obligates no one. Manmade laws, on the other hand, are always compulsory. To that extent, citizen obedience is never a choice. The text does not offer an in-depth review of natural laws. However, it offers a succinct, but thorough, assessment of the literature.
