Whether Adam in the state of innocence saw the angels through their essence?

Objections

Objection 1 : It would seem that Adam, in the state of innocence, saw the angels through their essence. For Gregory says (Dialog. iv, 1): "In paradise man was accustomed to enjoy the words of God; and by purity of heart and loftiness of vision to have the company of the good angels."
Objection 2 : Further, the soul in the present state is impeded from the knowledge of separate substances by union with a corruptible body which "is a load upon the soul," as is written Wis. 9:15. Wherefore the separate soul can see separate substances, as above explained (Question [89], Article [2]). But the body of the first man was not a load upon his soul; for the latter was not corruptible. Therefore he was able to see separate substances.
Objection 3 : Further, one separate substance knows another separate substance, by knowing itself (De Causis xiii). But the soul of the first man knew itself. Therefore it knew separate substances.
