Whether the separated soul knows all natural things?

Objections

Objection 1 : It would seem that the separated soul knows all natural things. For the types of all natural things exist in separate substances. Therefore, as separated souls know separate substances, they also know all natural things.
Objection 2 : Further, whoever understands the greater intelligible, will be able much more to understand the lesser intelligible. But the separated soul understands immaterial substances, which are in the highest degree of intelligibility. Therefore much more can it understand all natural things which are in a lower degree of intelligibility.
