 Marcel remains one of the most influential thinkers of the twentieth century, and his major themes continue to be relevant for the plight of humanity in the twentieth first century. Many find Marcel’s thought attractive because he emphasizes a number of significant ideas that have been influential in twentieth century thinking in both philosophy and theology: the attempt to preserve the dignity and integrity of the human person by emphasizing the inadequacy of the materialistic life and the unavoidable human need for transcendence; the inability of philosophy to capture the profundity and depth of key human experiences, and so the need to find a deeper kind of reflection; the emphasis on the human experience of intersubjectivity, which Marcel believes is at the root of human fulfillment; and a seeking after the transcendent dimension of human experience, a dimension that he believes cannot be denied without loss, and that often gives meaning to many of our most profound experiences. Marcel is also regarded as important by a range of thinkers in different disciplines because he presents an alternative vision to challenge the moral relativism and spiritual nihilism of his French rival, Jean Paul Sartre, and other representative existentialist philosophers (Marcel, 1995, pp. 47-90). For this important reason, his work continues to speak to many of our concerns today in ethics, politics, and religion.
