内容简介：
This is the first in a two-volume set, for theoretical physicists and philosophers of modern physics. It treats a puzzling and provocative aspect of recent quantum physics: the apparent interaction of certain physical events that cannot share any causal connection. These are said to be "entangled" in some way, but an explanation remains elusive. Abner Shimony, to whom the book is dedicated, and others, suggest the need to revive the category of what may be seen as a metaphysical potentiality. Abner has described these events without actions as "passion-at-a-distance": not active, but passive. The discussions gathered here are written by a team of scientists and philosophers seeking to shed new light on the most profound puzzles of our time.
