Piana Giovanni (April 5, 1940 – February 24, 2019) was an Italian philosopher.
He taught theoretical philosophy at the University of Milan from 1970 to 1999.
He was a disciple of Enzo Paci and wrote his dissertation on Husserl's unpublished works.
His philosophical position is characterised by the concept of phenomenology ("phenomenological structuralism") influenced by Husserl, Wittgenstein, and Bachelard.
Some indications about phenomenological structuralism are contained in the online articles: "Phenomenology as philosophical method" and "Die Idee eines phänomenologischen Strukturalismus".
His thought was oriented towards the philosophy of knowledge, the philosophy of music, and the fields of perception and imagination.
