Spinoza's Chapter 1. - of prophecy (Page 1)

The multitude consider prophecy as in a different category than ordinary knowledge. But since all knowledge comes from (Deus sive Natura) ordinary knowledge is not a bit inferior to prophecy.

The ordinary human mind is the source of explanations about natural phenomena and of ideas about morality and, thus itself, can be "a primary caue of Divine revelation."

The prophets did not hear a real voice. All men may be able to communicate with (Deus sive Natura) through the mind rather than physical speech.
