Although her argument about intelligence might remain opaque, it should be remembered that intelligence is
by definition outside of humans’ capacity for comprehension, and that Philosophy will eventually explain it better. Still, readers can understand the principle that each particular form of knowledge “includes [all] the inferior [ones]” by taking a straightforward example. People can
know certain things about apples, as a universal category (they are kind of round, they are red or green, they have stems and thin skin, etc.). Using this
rational knowledge, it is possible to
imagine an apple, and by using this imaginary mental picture of an apple, it is possible to learn what an apple would look and feel like. So
rational knowledge of an apple gives people the capacity to know about apples through the imagination and senses, too. Following this principle, God’s intelligence will include all three of the lower forms of knowledge, which Philosophy will eventually show is the reason that He can know what humans do before they do it.
