This paper analyses the criticisms put forward by the Scotists of the 17th century to Thomas Aquinas' commentators on the subject of the intellect's first object. What the intellect knows first, and what is the extension of human cognition, are the questions that Aquinas addressed in different places of the Summa theologiae, and that Scotus famously criticised.
From the 15th century on, the Scotists of the 17th century observed the tendency, among Aquinas' commentators, to adjust themselves to Scotus' opinion concerning this matter. The paper includes a collection of the texts they mention and focuses on this "shift" in the history of Aquinas' readings.
