This Article introduces and briefly explores some of the topics related to the value and ethics of water that were considered at the symposium, Precious, Worthless, or Immeasurable: The Value and Ethic of Water, which took place November 2-4, 2006, at the Texas Tech University School of Law. The purpose of the Symposium was to consider how this precious liquid is valued, assessed, and perceived with regard to law and regulations, economics and commerce, people and communities, culture and religion, and others aspects of society that are impacted by water. While far from a comprehensive analysis of the subject matter, this Article considers some of these topics as an introduction to these proceedings of the symposium.
