Atheism
In his Atheism: A Philosophical Justification, Martin cites a general absence of an atheistic response to contemporary work in philosophy of religion, and accepts the responsibility of a rigorous defense of non belief as his "cross to bear:"
The aim of this book is not to make atheism a popular belief or even to overcome its invisibility. My object is not utopian. It is merely to provide good reasons for being an atheist. … My object is to show that atheism is a rational position and that belief in God is not. I am quite aware that atheistic beliefs are not always based on reason. My claim is that they should be.
Martin took part in a number of written and internet debates with Christian philosophers.
In 1991 Martin and Keith Parsons provided atheistic critiques to Douglas Jones' propositions on The Futility of Non Christian Thought in a written debate, Is Non-Christian Thought Justifiable?, originally published in Antithesis magazine.
Martin had agreed to participate in a debate with Christian reconstructionist philosopher Greg Bahnsen on October, 26, 1994, at Rhodes College in Memphis, TN. Martin, however, pulled out of the debate on October 14, less than two weeks before the event was to have taken place, due to his stated objection to having the debate recorded.
He conducted a debate with John M. Frame over the internet in a series of articles and responses around Martin's 1996 article, "The Transcendental Argument for the Nonexistence of God".
An internet debate with Christian philosopher Phil Fernandes in 1997 over the existence of god was published as a book in 2000 titled: Theism vs. Atheism: The Internet Debate.
