There's no need for debate. `true` and `false` are the identity values 
for the AND and OR operations.

Well, you won't find any object in the empty collection for which it is 
not true.
May I refer you to https://en.wikipedia.org/wiki/Vacuous_truth?

Not knowing about something doesn't imply it would not exist :-) The 
identity element of multiplication is 1.
Have a look at https://en.wikipedia.org/wiki/Empty_product for further
