I am beginning to study Spiritualism, so this was a helpful historical read. It describes both the perspectives of the time period, in the context of developing understanding of psychological & related sciences, and also some practical exercises for developing aspects of our Higher Intelligence. Spiritualism truly blends the ability to experience psychic phenomena & a spiritual path that includes ethics, community & personal spiritual practice & development, far beyond what mere intellectual & physical science can offer or recognize, even today. This book does not delve into the religion of Spiritualism, but rather the aspects of psychic phenomena related to meduimship and such.
