I am starved for spirit. Although they occasionally fill me with awe, neither religion nor science inspires me with deep purpose and meaning. I worry that this is a widespread malaise, an existential depression infecting too many people in a world where consumerism spills in too easily to fill the void. Personally, I'm not inspired by money or power so the material world is a kind of hell to me. And, like most people, I'm afraid my lack of deep spiritual purpose inhibits me in making necessary sacrifices on behalf of the environment. Or on behalf of starving children. Or on behalf of human rights. Or on behalf of getting a job.
