Or just listen to Gene Roddenberry accept the 1991 Humanist Arts Award from AHA.
That's humanism! OK? :)
I watched as many of the Star Trek episodes in this video as I could with my children when they were young, and we talked about the issues and themes that were raised (another one of my favorite episodes that is not in this compilation is TNG's The Chase). And I think my children turned out pretty good. They also liked the Wizard of Oz and the Lion King. :)
