Every generation laughs at the old fashions, but follows religiously the new.
— Henry David Thoreau (http://www.literaturepage.com/read/walden-19.html)
No food, one problem. Lots of food, many problems.
Everyone without exception believes his own native customs, and the religion he was brought up in, to be the best.
Herodotus (440 BC) via http://www.overcomingbias.com/2019/01/most-progress-not-in-morals.html
