Works sometimes ascribed to Aquinas may well be texts of which he was not the author in any sense. What follows is a list of Aquinas's writings with respect to which there is not too much scholarly controversy concerning authenticity. They are cited by Latin titles commonly used for them, together with English translations of these. But note that we cannot always be sure of the titles which Aquinas gave to his writings (notably, in the case of the Summa theologiae and the Summa contra Gentiles). Within each category below, works are cited in roughly chronological order of composition, though in some cases this order is uncertain. For detailed discussions concerning the dating of Aquinas's writings, see Jean-Pierre Torrell, Saint Thomas Aquinas: The Person and His Work (Washington, D. C.: Catholic University of America Press, 1996).
