creates an ever-growing economy.

by developing space resources.
IV. The Education Argument - use space to make
learning interesting.
V. The Political Argument - remove competition
for finite resources.
VI. The Historical Argument - economic and
technological advances result from expansion.
VII. The Frontier Argument - frontiers provide hope,
room to grow, substitute for war.
VIII. The Cosmic Argument - "Because we are here."
IX. The New Mythology - maintain a sense of wonder.
X. The Fear - Entropy sucks.
XI. The Hope - It is our nature to move outward.
