Query: Myriad-Minded Mythologist!

This is Joseph Campbell at his most wide-ranging--from intense academic essays like his foreword to the Grimm Bothers' Tales to philosophical explorations of the place of myth in today's world like "Secularization of the Sacred" and "Symbol without Meaning." My favorite essay in the collection is "Bios and Mythos", where Campbell goes into the question of the biological basis for spiritual thought. Really mindblowing stuff!
