Mortimer Adler has always been ahead of his time. In 1982, before the current revival of interest in angels, Dr. Adler published The Angels and Us , an engaging look at the various images and hierarchies of angels (including guardian angels). Dr. Adler, the bestselling author of Ten Philosophical Mistakes , Aristotle for Everybody , and The Great Ideas , speculates on the existence of angels; why Jews, Christians, and Muslims believe in angels, and the ways angels have been viewed as objects of religious belief and philosophical thought. This is a wonderfully enlightening work on the affinities between angels and human beings.
