The ever-popular and highly readable C.S. Lewis has "done it again." This time with a book beginning with the premise "God is Love" and analyzing the four loves man knows well, but often understands little, Affection, Friendship, Eros and Charity, exploring along the way the threads of Need-Love and Gift-Love that run through all. It is written with a deep perception of human beings and a background of excellent scholarship. Lewis proposes that all loves are a search for, perhaps a conflict with, and sometimes a denial of, love of God. "Man approaches God most nearly when he is in one sense least like God. For what can be more unlike than fullness and need, sovereignty and humility, righteousness and penitence, limitless power and a cry for help?" To relate the human activities called loves to the Love which is God, Lewis cites three graces as parts of Charity: Divine Gift-Love, a supernatural Need-love of Himself and a supernatural Need-love of one another, to which God gives a third, "He can awake in man, towards Himself a supernatural Appreciative love. This of all gifts is the most to be desired. Here, not in our natural loves, nor even in ethics, lies the true center of all human and angelic life. With this all things are possible." From a reading of this book laymen and clergy alike will reap great rewards: a deeper knowledge of an insight into human loves, and, indeed, humans, offered with beauty and humor and a soaring description of man's search for God through Love.
