Michael L. Martin died unexpectedly in Boston on Wednesday evening, aged 83. He made a very large contribution to atheistic scholarship. His books included the following. Atheism: A Philosophical Justification (1991); The Case against Christianity (1993); The Big Domino in the Sky (1996); Atheism, Morality, and Meaning (2002); The Impossibility of God (2003); The Improbability of God (2006); and The Cambridge Companion to Atheism (2006).
