We travel together, passengers on a little space ship,
dependent on its vulnerable reserves of air and soil,
committed for our safety to its security and peace,
preserved from annihilation only by the work, care,
and I will say the love we give our fragile craft.

We cannot maintain it half comfortable, half miserable,
have confident, half despairing, half slave to the ancient
enemies of mankind, half free in a liberation of resources
undreamed until this day. No craft, no crew can travel
safely with such vast contradictions. On their resolution
depends the security of us all.
