| 0:00.0 | You can learn a lot about human wants from human don'ts. |
| 0:05.2 | The Code of Urunamu is the oldest legal text we know of. |
| 0:09.7 | It's written in Sumerian on terracotta tablets found in modern-day Iraq, |
| 0:14.6 | and it's about 4,000 years old. |
| 0:17.5 | You can read the translations. |
