Ben Lazare Mijuskovic has spent 40 years researching theories of consciousness in relation to human loneliness, using an interdisciplinary and "history of ideas" approach. In this book, Mijuskovic combines Kant's theory of reflexive self-consciousness with Husserl's transcendent principle of intentionality to describe the distinctive philosophical, psychological, and sociological roots of loneliness and intimacy. He argues that loneliness is innate, unavoidable, and constituted by the structure of self-consciousness itself.
