The Exploration of Space, by Arthur C. Clarke – 1954 [Bob Smallman]

on a technological front alone. 
Morals and ethics must not lag behind science,
otherwise (as our own recent history has shown)
the social system will breed poisons which will cause its certain destruction.

With superhuman knowledge there must go
equally great compassion and tolerance. 
When we meet our peers among the stars,
we need have nothing to fear save our own shortcomings.
