|Is, philosophy: the word “is” has different functions like expressing an identity e.g. A is B, attributing a property e.g. the sky is blue or being contained in a set e.g. "Heaven" is a concept. These functions must not be confused.|

"Is"/RyleVsAristoteles: "systematically misleading locutions", "is" should suggest the appearance of a thing/property relationship.
Error: the universal "human" is itself not a thing that breathes. Rather, it is to be interpreted as a class subordination - "if existence is a term of 2nd order, God cannot be a subject term" - rather predicate term like 'infinite beings' - RyleVsRussell: E.g. Pegasus: Problem not in the subject term, but in the predicate term.
