The Black Mask delves into the interplay between theology, sociology, and existentialism. It examines how modern individuals navigate issues of identity, alienation, and faith in an increasingly secular and fragmented world. Cooper uses the metaphor of the "black mask" to symbolize the hidden struggles people face when grappling with questions of meaning and authenticity. By drawing from philosophical and theological perspectives, the book challenges readers to confront the masks they wear and consider how these influence their understanding of self and community.
