When I think of Paul Kurtz, I think of three adjectives: Visionary, Indefatigable, and Productive.
Paul Kurtz was a visionary in many ways. Personally, I appreciated his recognition that the future of secular humanism had to include a more diverse demographic. The future of secular humanism cannot continue to ignore the more than 50 million people that we call Latinos/Hispanics in the United States, and he knew that.
Paul Kurtz was in the business of saving minds, not souls, and he was very good at it. He produced many followers who will continue his work. Paul Kurtz left us with organizations and other vehicles through which secular humanism continues to assert its place in the public square. Even his critics must acknowledge that.
