The present study is interdisciplinary in applying philosophy through its collaboration with psychology and literature. This article examines hope according to the two great thinkers; Rumi, a Muslim mystic and writer, and Gabriel Marcel, a Christian existentialist philosopher. The purpose of this study is to provide a basis for the work of philosophical counselors and psychotherapists. For this reason, the views of Richard Snyder, the theorist and founder of hope therapy in contemporary psychology, are also introduced in the present study to bring Rumi and Marcel's views on hope closer to the topics of hope therapy, and the similarities are derived from being used by philosophical advisors. According to the findings of this research, the hope that Rumi speaks of is a clear and guiding hope that, if used properly, can become a positive moral trait in human beings; The hope that arises from man's need for God and will always be the way to man's spiritual progress. Marcel also considers hoping a tool for faith and closeness to the higher being, which causes a person to be spiritually ready to serve other human beings. This spiritual preparation frees man from the snare of the shattered world of which Marcel speaks. By comparing Snyder's theory of hope and Rumi's view of hope, we find similarities between the views of these two philosophers in the components of hope. The examination of Snyder's theory of hope and Marcel's view of hope also reveals the intellectual similarity of the two thinkers on the vital role of hope in life.
