Addis specialises in the philosophy of Wittgenstein and related areas as well as having research interests in the philosophies of language, mind, and religion. His book Wittgenstein: Making Sense of Other Minds (1999) was described by Rom Harre as "a careful and subtle study" whose "scholarly merits are great". Wittgenstein and Philosophy of Religion (2001, co-edited with Robert Arrington) is "an interesting and valuable collection of essays", while Wittgenstein: A Guide for the Perplexed (2006) is "a clear, balanced and very recommendable book which gives a good idea of the complexity of Wittgenstein's philosophy".
