“The drive toward complex technical achievement offers a clue to why the US is good at space gadgetry and bad at slum problems.”

1963, UN speech
Context: Finally, in a field where the United States and the Soviet Union have a special capacity — in the field of space — there is room for new cooperation, for further joint efforts in the regulation and exploration of space. I include among these possibilities a joint expedition to the moon. Space offers no problems of sovereignty; by resolution of this Assembly, the members of the United Nations have foresworn any claim to territorial rights in outer space or on celestial bodies, and declared that international law and the United Nations Charter will apply. Why, therefore, should man's first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction, and expenditure? Surely we should explore whether the scientists and astronauts of our two countries — indeed of all the world — cannot work together in the conquest of space, sending someday in this decade to the moon not the representatives of a single nation, but the representatives of all of our countries.

In some published transcripts or quotations of this speech a variant of this statement appears immediately before the quote by Churchill below, but was not said during Reagan's televised address on (27 October 1964). Though he did make variations of the speech elsewhere it is unclear exactly when and where he may have said used these precise words:
: They say the world has become too complex for simple answers. They are wrong. There are no easy answers, but there are simple answers. We must have the courage to do what we know is morally right.
Later variant: For many years now, you and I have been shushed like children and told there are no simple answers to the complex problems which are beyond our comprehension. Well, the truth is, there are simple answers, they just are not easy ones.
