This is an enlightening and a very respectful debate which covers many of the philosophical explanations for consciousness. In it, the debater that starts to speak first is Hamza Andreas Tzortzis, a Muslim convert, who gives a scrupulous run down of the naturalistic explanations for consciousness and, ultimately, why they all fail. Then he presents an alternative argument, which is a theistic explanation. The other debater, Professor Peter Simons (who is an atheist and a philosopher), said that he agrees with everything his opponent said regarding the subject except for his conclusion, i.e. the idea that a greater sentient being is necessary in order for consciousness to exist. But whether you yourself believe in God or not, the various explanations presented are worth pondering on as they shed light on the mystery of consciousness from several fields of study, e.g. from a biological, theological, and a philosophical perspective, and how some of the explanations even complement each other.
