Science fiction is the literature of change.
"The novel is a mirror that reflects the complexities of human existence."
The main thing is to be moved, to love, to hope, to tremble, to live.
The greatest obstacle to being heroic is the doubt whether one may not be going to prove one's self a fool; the truest heroism is to resist the doubt, and the profoundest wisdom to know when it ought to be resisted, and when it be obeyed.
