This book presents, for the first time, a critical edition and English translation of the natural philosophy section of the first major thirteenth-century Hebrew encyclopedia of science and philosophy and assesses Judah ha-Cohen's place in the history of Jewish philosophy.

One of the last Army expeditions in the region, this was an exploration of parts of New Mexico, Utah, and Colorado during the summer of 1859, northward out of Santa Fe along the Old Spanish Trail, to discover if there were a practical railroad or wagon route through the San Juan River country to the southern settlements of Utah Territory (in case of further armed conflicts like the "Utah War"), and on to the west coast. The report found the mountainous terrain impractical for a railroad, and the weather too severe for permanent settlement. The Civil War delayed publication.
