Sin is geographical.”
Bertrand Russell, philosopher, mathematician, author, and Nobel laureate (1872–1970)
I really like this one: what is permissible in our country, one period of civilization, and even in one’s family may be seen as wrong or even evil and subject to punishment in another time, in another place. Owning slaves was once respectable, honor killings are still condoned in some countries, using swearwords may be acceptable in some families.
