Wisdom from the Late Bronze Age, by Y. Cohen [author]

This volume presents the original texts and annotated translations of a collection of Mesopotamian wisdom compositions and related texts of the Late Bronze Age (ca. 1500–1200 B.C.E.) found at the ancient Near Eastern sites of Hattuša, Emar, and Ugarit. These wisdom compositions constitute the missing link between the great Sumerian wisdom corpus and early Akkadian wisdom literature of the Old Babylonian period, on the one hand, and the wisdom compositions of the first millennium B.C.E., on the other. Included here are works such as the Ballad of Early Rulers, Hear the Advice, and The Date-Palm and the Tamarisk, as well as proverb collections from Ugarit and Hattuša. A detailed introduction provides an assessment of the place of wisdom literature in the ancient curriculum and library collections

September 11, two years later

Like other historical milestones, the second anniversary of the September 11, 2001 terrorist attack in the United States provides a good opportunity for critical evaluation. It invites an interim assessment of the successes and failures of the offensive launched by the US-led international coalition against terrorism and terrorist organizations, first and foremost al-Qaeda and its affiliates. Examining the unique..

Relating Knowledge and Coordinated Action: The Knowledge of Preconditions Principle

The Knowledge of Preconditions principle (KoP) is proposed as a widely applicable connection between knowledge and action in multi-agent systems. Roughly speaking, it asserts that if some condition is a necessary condition for performing a given action A, then knowing that this condition holds is also a necessary condition for performing A. Since the specifications of tasks often involve necessary conditions for actions, the KoP principle shows that such specifications induce knowledge preconditions for the actions. Distributed protocols or multi-agent plans that satisfy the specifications must ensure that this knowledge be attained, and that it is detected by the agents as a condition for action. The knowledge of preconditions principle is formalised in the runs and systems framework, and is proven to hold in a wide class of settings. Well-known connections between knowledge and coordinated action are extended and shown to derive directly from the KoP principle: a "common knowledge of preconditions" principle is established showing that common knowledge is a necessary condition for performing simultaneous actions, and a "nested knowledge of preconditions" principle is proven, showing that coordinating actions to be performed in linear temporal order requires a corresponding form of nested knowledge.Comment: In Proceedings TARK 2015, arXiv:1606.0729
