We are explorers. We are at present, as far as we know, the only explorers of the universe. For a long time we thought that ours was the only planet that could support life. Then we found others that could – a few. For still longer we thought we were unique – the only intelligent form of life – a single, freakish pinpoint of reason in a vast, adventitious cosmos – utterly lonely in the horrid wastes of space.… Again we discovered we were mistaken…But intelligent life is rare… very rare indeed… the rarest thing in creation…But the most precious…For intelligent life is the only thing that gives meaning to the universe. It is a holy thing, to be fostered and treasured.Without it nothing begins, nothing ends, there can be nothing through all eternity but the mindless babblings of chaos…Therefore, the nurture of all intelligent forms is a sacred duty. Even the merest spark of reason must be fanned in the hope of a flame. Frustrated intelligence must have its bonds broken. Narrow-channelled intelligence must be given the power to widen out. High intelligence must be learned from. That is why I have stayed here.
