One hundred years ago, if someone said, 'damn,' people would take notice. Now, you can say almost anything. Secrets are the same way. Once upon a time when a secret was revealed, people paid an enormous amount of attention to it.

We of course have our problems, to say the least, in comportment towards ourselves and our environment, but admittance to the cosmos and the spatial infinity and temporal immortality it provides may well be just the remedy for these age-old problems.

If two or three hundred years from now an earthbound civilization is dying ... and they look back at the opportunity that we have here at the close of the twentieth century to move out into space and they see that we didn't do anything with it ...

Let us join with the peoples and cultures of this planet, the diversities of its perspectives and religions and science, so we can leave it-not behind, but as a springboard to something better.

I firmly believe that we who are alive and can think today-in the closing years of the 20th century-have a commitment to our species to make sure that the flicker of movement we have thus managed in space stays sufficiently kindled so that the people of the 21st century can build upon and extend the human abode from Earth to the cosmos beyond.
