Special Centenary Edition celebrating the birth of CS Lewis.
The four loves distinguished in this book are affection, friendship, eros and charity. It observes how each merges into another, without losing sight of the necessary and real difference between them.
CS Lewis also warns of the deceptions and distortions which can render the first three - the natural loves - dangerous without the sweetening grace of charity, the divine love which must be the sum and goal of all.
