Closer to Truth is a continuing television series on PBS[1][2][3][4] and public television originally created, produced and hosted by Robert Lawrence Kuhn. The first premiere series aired in 2000 for 2 seasons, followed by a second series aired in 2003 for a single season. Kuhn's presentation, Asking Ultimate Questions,[5] is the foundation of Closer To Truth.

The third series of the program, Closer to Truth: Cosmos. Consciousness. God, launched in 2008, with 20 full seasons to date. Kuhn is the creator, executive producer, writer and presenter of the series.[6] Peter Getzels is the co-creator and producer / director.[7][8]

The show is centered on on-camera conversations with leading scientists, philosophers, theologians, and scholars, covering a diverse range of topics or questions from the size and nature of the universe (or multiverse), to the existence and essence of God, to the mystery of consciousness and the notion of free will.[9][10][11]
