Drawing on the fields of psychology, literature, and philosophy, argues that loneliness has been the universal concern of mankind since the Greek myths and dramas, the dialogues of Plato, and the treatises of Aristotle. Author Ben Lazare Mijuskovic, whose insights are culled from both his theoretical studies and his practical experiences, contends that loneliness has constituted a universal theme of Western thought from the Hellenic age into the contemporary period. , he shows how man has always felt alone and that the meaning of man is loneliness. Presenting both a discussion and a philosophical inquiry into the nature of loneliness, Mijuskovic cites examples from more than one hundred writers on loneliness, including Erich Fromm, Frieda Fromm-Reichmann, Clark Moustakas, Rollo May, and James Howard in psychology; Thomas Hardy, Joseph Conrad, James Joyce, Thomas Wolfe and William Golding in literature; and Descartes, Kant, Kierkegaard, Nietzsche, and Sartre in philosophy. Insightful and comprehensive, demonstrates that loneliness is the basic nature of humans and is an unavoidable condition that all must face.
