A student of his as a young man at the Università Cattolica del Sacro Cuore was Cardinal Angelo Scola, who later served as Archbishop of Milan.

In April 2019, Severino was interviewed by the then Italian premier Giuseppe Conte who defined him a focal point of the theoretical philosophy at an international level.

Even much earlier, some Heideggerian working notes testify how Martin Heidegger followed the very young Severino (from a study by Francesco Alfieri and Friedrich von Herrmann).

Aldo Stella, author of numerous works on theoretical philosophy, has addressed relevant criticisms of his thought, which find expression, in particular, in two volumes devoted to The Original Structure ("La struttura originaria").
