In Martin-Löf type theory (MLTT), we evaluate shallow embedding as the following conjecture: “if we add the rewrite rule ∀x. f x (not x) = true, the expression f true false will not be rewritten to true, since it does not rigidly match the not x on the left hand side”. The conjecture is not tautologous, hence refuting shallow embedding in MLTT and forming a non tautologous fragment of the universal logic VŁ4.
