Each of us conducts our lives according to a set of assumptions about how things work: how our society functions, its relationship with the natural world, what's valuable, and what's possible. This is our worldview, which often remains unquestioned and unstated but is deeply felt and underlies many of the choices we make in our lives. We form our worldview implicitly as we grow up, from our family, friends, and culture, and, once it's set, we're barely aware of it unless we're presented with a different worldview for comparison.
