Spinoza's "Ethics" has long been considered the most complete attempt at explaining and defending pantheism. Historically, however, pantheism has had numerous forms. Michael P. Levine manages to disentangle the concept from Spinoza to present a broad philosophical and historical survey of pantheism.
The book deals with definitions of pantheism and examines critical distinctions between them. It analyzes both historical and contemporary concepts of pantheism. Levine compares pantheism to theism, discussing how some philosophical problems usually associated with theism can be recast in pantheism and how, if at all, they might be resolved. He also looks at the relationship between belief and practice in pantheism.
