Which works by Gabriel Marcel explored being hope and creative fidelity?

Gabriel Marcel explored the themes of hope and creative fidelity across several of his major philosophical works.

• Du refus à l’invocation (1940; Creative Fidelity): This work specifically addresses the concept of creative fidelity, which Marcel described as a way of being with another person that requires an individual to remain open to them.12
• Homo viator: prolégomènes à une métaphysique de l’espérance (1944; Homo Viator: Introduction to a Metaphysic of Hope): This text serves as a primary exploration of his metaphysics of hope.1
• Mystère de l’être (1951; The Mystery of Being): As his most systematic presentation of ideas, this two-volume work further elaborates on his central themes, including the "concrete approaches" of faith, fidelity, hope, and love, which he categorized as mysteries rather than problems.13

These concepts are deeply rooted in his phenomenological approach, where he argued that such experiences involve commitments that elude conceptual description and are best understood as being pledged to a transcendent reality.23
