ABSTRACT
The author of this chapter has produced three arguments against the validity of 'existence'. They are: its lack of coherence with a 'world' and necessary connection; the contradictions or paradoxes engendered by existence in a pluralistic world; and the deduction that physical things are 'how' rather than 'that' they are. But as far as the positive definition of existence itself goes, there is a fourth and the most telling argument against it in the form of exposing the membership fallacy in its various philosophical guises. The relativity of existence, that it operates only at 'levels' and in contexts, should have been plain from our metaphysics. This intellectual error - belonging - raised a host of conceptual problems, even absurdities. Sometimes people say that there is no level on which we can absolutely say that something does not exist. Anything has a context in which it does exist.
