Idle Mendacity has tagged everybody with the meme of “Quote the Gospel verses of your birthday.” I decided to do the Jewish version and quote a verse from my haftarah:
11 Like a partridge hatching what she did not lay,
So is one who amasses wealth by unjust means;
In the middle of his life it will leave him,
And in the end he will be proved a fool.
If we apply the above to a science-fiction context, we see that truly evil extraterrestrials are unlikely to achieve or to keep space travel, so we don't have to worry that
much about alien conquest.
