How do we know?

[MSahla]

Might a dumb question for some people, but how do we know if a character can do this:

a being on a level in which their power influences the space of all logically possible worlds (equivalent to "logical space" governed by the three laws of thought), being characters who either have the ability to actualize arbitrarily large worlds, or embody the framework of such worlds itself. (High 1-A+)

Without mentioning any "logical possible worlds" or some stuff like that? Or is it specifically should mention those kind of words?
