This experience, which united study to work, hard but also formative (in the meantime he had changed jobs, moving to Orologerie Binda to have more free time to devote to study), increasingly sharpened his sensitivity towards social problems, which will constitute later, even when he became high school professor at Manzoni in Milan and then in charge of Aesthetics at the University of Pavia, the main subject of his cultural path, both philosophical and human.
Having obtained his primary school teacher diploma in 1933, he was transferred to Motta Visconti, in the same institute where the poet Ada Negri had taught a few years earlier.
In the early post-war years, after having actively participated in the partisan struggle, Dino Formaggio joined the University of Milan as an assistant to the chair of Aesthetics.
He also collaborated with the journal Philosophical Studies and published some essays, such as Phenomenology of Art Technique, resuming and expanding his degree thesis.
Formaggio moved to Veneto in 1963, after having won the competition for the chair as Full Professor of Aesthetics at the University of Padua, between 1966 and 1978, a very difficult period for the whole Italian academic world and in particular for that of Padua due to the strong tensions caused by the student revolt first, and then by the nascent armed terrorism, first assuming the position of dean of the Faculty of Education and then that of pro-rector.
