I have been teaching my literature classes that there is an intersection between the culture/art/literature we consume and what we believe. We should approach culture with wonder and imagination, yes, but also critically, with our minds. Here is a page with resources to continue this discussion. Some are links to other sites, some to specific lectures, presentations, or interviews. Most deal additionally with philosophy and other realms of thought.
