Divine and angelic cognition in St. Thomas Aquinas

In the first part of the Summa theologiae St. Thomas Aquinas analyzes the cognition in God, angels and human beings; he does that by comparing and juxtaposing them. On the one side, the questions concerning divine cognition, such as the identity of the divine cognition and the divine substance, its nondiscursivity, its scope or future contingents are considered in the articles dedicated to the angels. On the other side, the proper characteristics of the human cognition in the part of the Summa on human soul, such as the active intellect, lack of inborn intelligible species, the inductive procedure in the abstracting from sense cognition, the cognition of the particulars, those problems are analyzed in the part on angelic cognition too. So, there is a structural symmetry of corresponding questions in the Summa on divine, angelic and human cognition.
