First therefore let us seek the dignity of knowledge in the archetype or first platform, which is in the attributes and acts of God, as far as they are revealed to man and may be observed with sobriety; wherein we may not seek it by the name of Learning; for all Learning is Knowledge acquired, and all Knowledge in God is original: and therefore we must look for it by another name, that of Wisdom or Sapience, as the Scriptures call it.
