"Who are we? Where do we come from? Why are we this way and not
some other? What does it mean to be human? Are we capable, if need
be, of fundamental change, or do the dead hands of forgotten ancestors
impel us in some direction, indiscriminately for good or ill, and beyond
our control? Can we alter our character? Can we improve our societies?
Can we leave our children a world better than the one that was left to us?
Can we free them from the demons that torment us and haunt our civilization?
In the long run, are we wise enough to know what changes to make?
Can we be trusted with our own future?"
- Carl Sagan, Shadows of Forgotten Ancestors (p.4)
