They used to say, if man could fly, he'd have wings. But he did fly;
he discovered he had to. Do you wish that the first Apollo mission
hadn't reached the moon, or that we hadn't gone on to Mars and
then to the nearest star? That's like saying you wish that you still
operated with scalpels and sewed your patients up with catgut, like your
great, great, great-grandfather used to do ... Dr. McCoy is right in
pointing out the enormous danger potential in any contact with life
and intelligence as fantastically advanced as this. But I must point
out that the possibilities -- the potential for knowledge and
advancement is equally great. Risk -- risk is our business.
