Paganism is among the fastest-growing religions in the world. It is most commonly expressed in the celebration of seasonal festivals, such as the solstices, through the use of 'magic' and in attempts to make changes in the world or in individual consciousness. Among the number of different paths to paganism are Druidry, Wicca, Heathenry and Goddess Spirituality, all of which celebrate nature. Paganism engages with some of the chief concerns of this age: ecology and feminism, for example. It draws on ancient sources but allows individuals to explore their current relevance. At its heart, Paganism encourages people to live respectfully alongside all life and not to raise humanity above any other species. Graham Harvey explores Paganism's appeal and gives a clear insight into its key beliefs.
