“And we, we who embody the local eyes and ears and thoughts and feelings of the cosmos, we have begun at least to wonder about our origins — star stuff contemplating the stars, organized collections of ten billion billion billion atoms, contemplating the evolution of nature, tracing that long path by which it arrived at consciousness here on the planet earth, and perhaps throughout the cosmos.”
