Thomas Hardy and then Simon Armitage wrote their ‘Convergences of the Twain’ to address loss. Hardy wrote about the sinking of the Titanic, Armitage about the 9/11. Both are reported not too empathetic — I do not intend to analyze them. The deuce here is about the notion of convergence.
Within the sociologic perspective, we may refer to a symbolic convergence theory – Rene Girard would call it the scapegoat syndrome. Psychology would have convergence belong with the so-called ‘crowd psychology’. Some linguistic trends will have convergence for influences among languages, see a project by the University of Manchester.
Psycholinguistics will have convergence for a natural process in which language syntax, semantics, and sound come together. The perspective is individual, that is.
