The closest thing to religion for me would probably be the worldview and ethos exemplified in Star Trek: Next Generation. I suppose I am a secular humanist.

STNG was a very idealistic show. Instead of deux ex machina endings, science provided the solutions. Without appealing to gods, humankind nevertheless acted with a strong moral sense of justice and fairness. And rather then impose their own moral system on other peoples, humankind strove to uphold the Prime Directive. They didn't always succeed; but they always tried. The fortitude of their beliefs impressed me greatly:

The principles they upheld transcended their lives.
