10,000 BC paragraph 48a
Then there was the system of the strata. On the intensive continuum, the strata fashion forms and form matters into substances. In combined emissions, they make the distinction between expressions and contents, units of expression and units of content, for example, signs and particles. In conjunctions, they separate flows, assigning them relative movements and diverse territorialities, relative deterritorializations and complementary reterritorializations. Thus the strata set up everywhere double articulations animated by movements: forms and substances of content and forms and substances of expression constituting segmentary multiplicities with relations that are determinable in every case. Such are the strata. Each stratum is a double articulation of content and expression, both of which are really distinct and in a state of reciprocal presupposition.
