"Above all, Albert Einstein was a true believer in the scientist's duty to communicate with the public...those attending heard not much more than the words that began his speech: "If science, like art, is to perform its mission truly and fully, its achievements must enter not only superficially but with their inner meaning into the consciousness of the people." This always has been and always will be, the dream of Cosmos. When I stumbled upon Einstein's rarely quoted words of that night during some random late-night wandering on YouTube, I found the credo for 40 years of my life's work. Einstein was urging us to tear down the walls around science that have excluded and intimidated so many of us-to translate scientific insights from the technical jargon of its priesthood into the spoken language shared by us all, so that we may take these insights to heart and be changed by a personal encounter with the wonders they reveal...We didn't know that particular Einstein quote when Carl and I began writing the original Cosmos in 1980 with astronomer Steven Soter. We just felt a kind of evangelical urgency to share the awesome power of science, to convey the spiritual uplift of the universe it reveals, and to amplify the alarms that Carl, Steve, and other scientists were sounding about our impact on the planet. Cosmos gave voice to those forebodings, but it was also suffused with hope, with a sense of human self-esteem derived, in part, from our successes in finding our way in the universe, and from the courage of those scientists who dared to uncover and express forbidden truths."
