It could further be said that love becomes necessary as a special communication code only when others' emotions and images of the world are so strongly individualized – and that means, have become so contingent – that one can no longer be sure of them, and therefore, according to cultural standards, one has to love for its own sake. And even art, as a communication medium, depends on increased contingency, i.e. the contingency of works manifestly produced, but no longer sustained by the context of specific, lifeworld purposes.

XREF: Connects to Luhmann's systems theory on social differentiation and contingency as drivers of symbolic media.
