Some twelve years ago, when I first became (as a fellow druid put it) gods-bothered, there were very few people to ask who the gods were, let alone question what it meant that they actually existed. Fortunately, I came across John Michael Greer's A World Full of Gods and finally understood where to begin. Especially in this delightful update, Greer expands and moves beyond a compelling defence of polytheism, to an explanation of the rich and dazzling moral, cultural, and even political consequences of a world full of many truths, many desires, many forces, and many, many gods.
