consider two sets: set a and set b. both set a and b contain all horses, ane nothing else. they are always equivalent.
Sure, but does the set of all sets that don’t include themselves include itself?
Easy. If and only if the integer sequence A053169 contains the number 53169
Yesn’t.
set a contains all horses. set b contains all ponysonas
Gotcha. So all horses are purple?
But how can set b contain all of the horses if they’re already in set a???
