Gabriel Marcel's leading questions were "Who am I? Is life empty or full?" In other words, what is a person's authentic potential and what meaningful fulfillment one can hope for? Drama was always the first form of inquiry for Marcel. His dramatic imagination envisioned concrete individuals in particular situations of conflict. As a drama unfolds, the differing fundamental attitudes of various protagonists become evident. Marcel had a distinguished career. An Existential Dramatist and Philosopher, he wrote some thirty plays and a similar number of philosophic works that essentially were his search to find meaning and value in his own life. Referring to his thought and life's work Marcel wrote, in "The Secret is in the Isles," that he saw his dramas as islands. One lands on an island with both feet. Audiences, or readers, of existential drama are moved to enter wholeheartedly into the situation. He then sees his philosophic writings as the continents. They can be mapped out, juxtaposed, and then compared and contrasted to the thought of other philosophers whose boundaries are contiguous to them. In "The Invisible Threshold," the preface to his first volume of published plays, Marcel points out that his dramas deal with the spiritual level of human experience for without this transcendent dimension our lives would be diminished significantly. In this volume we present two of his plays, A Mystery of Love and The Posthumous Joke.
