Epistemology
Soul or mind harmonizes body and has inherently moving elements, as do other body parts, such as blood. Souls transmigrate from body to body.
Thought is deduction using logic and number. Knowledge is about mathematics and numbers. Truth known by mind is the same for all people, because they have the same mind elements, but opinion is individual, because bodies mix different elements.
Perception is imperfect, because it is about the physical world, which is only a copy of the true world. Sensory knowledge comes when moving object elements enter body and meet moving body elements. Like, or opposite, moving elements join, or recognize, each other. Only like or opposite can perceive object.
Metaphysics
Universe has order through numbers, which express all relationships. Universe has ten opposites.
