Think As Wise Men Do,

Thinking Is Different From Perceiving And Is Held To Be In Part Imagination, In Part Judgment

Every Formed Disposition Of The Soul Realizes Its Full Nature In Relation To And Dealing With That Class Of Objects By Which It Is Its Nature To Be Corrupted Or Improved.

In [the Soul] One Part Naturally Rules, And The Other Is Subject, And The Virtue Of The Ruler We Maintain To Be Different From That Of The Subject; The One Being The Virtue Of The Rational, And The Other Of The Irrational Part. Now, It Is Obvious That The Same Principle Applies Generally, And Therefore Almost All Things Rule And Are Ruled According To Nature.

The Ensouled Is Distinguished From The Unsouled By Its Being Alive. Now Since Being Alive Is Spoken Of In Many Ways, Even If Only One Of These Is Present, We Say That The Thing Is Alive, If, For Instance, There Is Intellect Or Perception Or Spatial Movement And Rest Or Indeed Movement Connected With Nourishment And Growth And Decay. It Is For This Reason That All The Plants Are Also Held To Be Alive . . .

Since We Think We Understand When We Know The Explanation, And There Are Four Types Of Explanation (one, What It Is To Be A Thing; One, That If Certain Things Hold It Is Necessary That This Does; Another, What Initiated The Change; And Fourth, The Aim), All These Are Proved Through The Middle Term.
