Many Facets of Love [PDF ebook] 
Philosophical Explorations

Poets, theologians, romantics, scientists, and revolutionaries alike have explored the many facets of love. Judging by the wide use of the word "love" and the high praise it typically receives, we might think that philosophers have thoroughly analyzed love. But this is not the case. This book takes a step toward rectifying the neglect of a philosophical analysis of love. It brings together fifteen philosophical perspectives that explore some of love’s most important facets. Most of the essays have theistic or religious concerns in mind.
