"I am proud to be a human being. I believe that we have come this far by the skin of our teeth. That we always make it just by the skin of our teeth, but that we will always make it. Survive. Endure. I believe that this hairless embryo with the aching, oversized brain case and the opposable thumb, this animal barely up from the apes will endure. Will endure longer than his home planet -- will spread out to the stars and beyond, carrying with him his honesty and his insatiable curiosity, his unlimited courage and his noble essential decency.
This I believe with all my heart."
Robert A. Heinlein when he appeared on This I believe.
