Esolen began teaching English at
Providence College in 1990, becoming a full professor in 1995. He is a critic of "diversity" training and guidelines as practiced at many American colleges and universities. In the summer of 2016, he remarked, "What counts for them as 'diversity' is governed entirely by a monotonous and predictable list of current political concerns. If you read a short story written in English by a
Latina author living up the road in
Worcester, that counts as 'diverse,' but if you read a romance written in Spanish by a Spanish author living in Spain four hundred years ago, that does not count as 'diverse.'" In September 2016,
Crisis Magazine published an article by Esolen titled "My College Succumbed to the Totalitarian Diversity Cult." The Rev.
Brian Shanley, O.P., President of Providence College at the time, publicly distanced himself from Esolen's statements by claiming "that he speaks only for himself. He certainly does not speak for me, my administration, and for many others at Providence College who understand and value diversity in a very different sense from him." ==Subsequent career==
