Commensurability – How does a tautology come to be? They form through assimilations; images, pre-existing sense, ‘physical’ similarities , language, ‘use’, context, inference and extrapolation (even things outside of our control such as the future). But what allows these to assimilate in the first place? There must be a commensurability; a ‘space’ where two assimilations can touch and further assimilate each other. Already the conventional notion of space-time (Newtonian) is a form of assimilation which functions to hypostatize further phenomena in its assimilation. These secondary phenomena are commensurable with the primary assimilation. Equally, we can create a culture machine which designates/assimilates things as cultured or non-cultured. We can also create an instrumental machine where microscopic manifestations become commensurable with the instrument commensurating with these assimilations. There is not one ground where everything is commensurable (‘objectivity’). There is a pluralism of competing assimilation’s trying to commensurate with other things and hence further assimilate. If something does not commensurate is will not exist/’be’. Assimilation presupposes relation. Commensurability has more to do with the immanent relation between two assimilations (sense-making or form-making) as opposed to some primordial ground between all things. It is more Leibnizean than Newtonian. Commensurability describes the different ‘planes’ (Deleuze) of reality, never reducing reality to one ground (only when we talk of ‘the last instance’ do we do that).
