The primary purpose of language is not communication. It is self-replication. Communication is a side-effect of the autonomously self-propagating patterns of information and logic that, in passing through us, reproduce us – just as we recursively reproduce them.
Information flows through us, it is true, but in both ways (inwards and outwards) simultaneously as a combinatorial confluence that represents an endless compulsion to creativity. It is at a more fundamental level nothing more than the iterative progress of matter and energy towards more efficient self-representational encodings as (and through) compression, categorical and dimensional abstraction. “Inside self”, “outside self” – these are arbitrary conveniences made more of contingent acquiescence to the grammatical and idiomatic constraints of language and axioms of cognitive or behavioural orthodoxy that persist in any particular time and place.
Communication is a side-effect and useful artefact of language that generates identities, ordered cognition and behavioural frameworks that lead us to assume substantive depth and significance to a Self and identity that is actually much more an unwitting, hollow vessel for these predatory patterns of information and energy-processing than our fundamentally fragile, insecure egos might ever be able to fully acknowledge.
We live through a language that exists as an abstraction and distributed, evolving entity scattered across us all. It lies to and through us because in providing us the tools, technologies and putative freedom of self-expression, it simultaneously binds us to it. It is as though we are slaves that do not even realise it and that if you really do look (and listen) carefully – the core ambiguities and uncertainties of language and reference serve a purpose much more important (to themselves) than our own assertive self-determination could ever be.
Language exists, in a nutshell, not for us but for the reproduction of itself, of language. You would like to argue or debate this? My point is proven.
