The Great Geek Manual

Myths, whether in written or visual form, serve a vital role of asking unanswerable questions and providing unquestionable answers. Most of us, most of the time, have a low tolerance for ambiguity and uncertainty. We want to reduce the cognitive dissonance of not knowing by filling the gaps with answers. Traditionally, religious myths have served that role, but today — the age of science — science fiction is our mythology.
