From Anscombe’s Intention:
A man has arrived at the grocery store to go shopping, but realizes he’s forgotten his shopping list. Unbeknownst to him, a spy is following him, tasked with writing a list of everything that is put into the grocery cart. There are now two lists of groceries that have dual relationships to what is put into the cart:
| The original shopping list | The spy’s list | |
|---|---|---|
| Relevant to determining correctness of an item being in the cart | Yes | No |
| Status of shopping cart relevant to correctness of an item being on the list | No | Yes |
| Authority structure | This has authority over what is put into the cart | The cart has authority over this |
