@JLNobody,
Postmodernists such as Derrida pointed out that a key issue regarding the word "everything" is not
thinghood in the sense of "objective status" but
assertions of "what is the case". Such assertions
only have communicative/semantic import relative to their negation "what is not the case".
In Derrida's terminology such assertions
privilege one side of an existential logical complement, and such privileging is contextually dynamic and potentially transient.
This argument regarding
contextual assertions rather than
ontological status is part of the philosophical movement focusing on language (
die Kehre) and abandoning attempts at traditional analysis such as logical positivism. It has its roots in post Kantian phenomenology and points to language as
constructive of "reality" rather than descriptive of it. In
Gestalt terms, it stresses the inextricability of "background" and "focus".
