Memoirist Akash Kapur was raised in an intentional community in India, then moved to the U.S. at age 16. He's seen the idealism of people trying to remake human society and renounce materialism. He's also seen how idealism and spirituality can turn into zealotry--and how individuals can become victims of their own search for perfection. Kapur writes about the reality of utopian communities in 'Better to Have Gone: Love, Death, and the Quest for Utopia in Auroville.'Kevin Whitehead reviews a new Bill Evans anthology.
