It's pretty obvious from any standpoint.

all([True, True] + []) is equivalent to `True and True and ?`. If you replace ? with False then all() will never return True in any case because given any list you can always create an equivalent list by appending [] which would taint the list to always return False on all(). Obviously nobody wants all() to return False on a valid list and the concept of tainting a list is pretty stupid so True is the only option. If you replace ? with True you can add as many empty lists as you like which is the desired behavior.

all([True, True] + [] + [] + []) == True and True and True and True and True

If it was obvious from any standpoint, we obviously wouldn't be having this blog post or this discussion thread.

Natural language - the natural way to think about things - does not always intuitively translate over to predicate logic. If you disagree with that, you should try teaching it to a class of high schoolers.

Lol, I used to believe that logic was an intrinsic faculty of human reason, and then I taught a bunch of freshmen.
