The path we have chosen for the present is full of hazards, as all paths are; but it is one of the most consistent with our character and our courage… - John F. Kennedy

This is a great country and requires a good deal of all of us, so I can imagine nothing more important than for all of you to continue to work in public affairs and be interested in them, not only to bring up a family, but also give part of your time to your community, your state, and your country.

My fellow citizens: let no one doubt that this is a difficult and dangerous effort on which we have set out. No one can see precisely what course it will take or what costs or casualties will be incurred. Many months of sacrifice and self-discipline lie ahead--months in which our patience and our will will be tested--months in which many threats and denunciations will keep us aware of our dangers. But the greatest danger of all would be to do nothing.

We may be proud as a nation of our record in scientific achievement--but at the same time we must be impressed by the interdependence of all knowledge. I am certain that every scholar and scientist here today would agree that his own work has benefited immeasurably from the work of the men and women in other countries. The prospect of a partnership with Soviet scientists in the exploration of space opens up exciting prospects of collaboration in other areas of learning. And cooperation in the pursuit of knowledge can hopefully lead to cooperation in the pursuit of peace.
