Law, is defined to be any thing that is altogether uncertain, or what may or may not be.

Possibility, also denotes a non-repugnance to existing, in any thing that does not any way exist.

Possible, is sometimes opposed to real existence, and is understood of a thing, which, though it actually does not exist, yet may exist; as a new star.
