This in-depth study of Thomas Aquinas' Quaestio de Attributis binds together the findings of previous research on the unique history of this text by reconstructing the historical circumstances surrounding its composition, shows that the Quaestio contains Aquinas' final answer to the dispute on the divine attributes, and thoroughly examines his interpretation of Maimonides' position on the issue of the knowledge of God by analysing this and other texts related to it chronologically and doctrinally.
