THE RATIONAL SOUL

THE RATIONAL SOUL

The rational soul, which is defined as a primary perfection for an organic natural body inasmuch as this body can act by rational choice and grasp the universals, is divided into the practical and the theoretical intellects. The practical intellect seeks knowledge in order to act in accordance with the good in its individual body, its family and its state. It must, therefore, know the principles for properly managing the body, the family and the state, that is, ethics, home management and politics. The practical intellect is the rational soul turning its face down¬ward. The function of the theoretical intellect is to know just for the sake of having the universals (the realities or natures of things). Some of these natures, such as God and the intellect, cannot attach to movement; knowledge of them is metaphysics. Other natures, such as unity, can attach to movement but do not; knowledge of them is mathematics. Still other natures, such as humanity and squareness, can attach to movement either in reality and thought, such as humanity, or in reality but not in thought, such as squareness. Knowledge of these is physics.
The theoretical intellect is the rational soul with its face upward. The practical intellect looks up to the theoretical one and moves its body accordingly. In this, the practical intellect is similar to :the celestial soul that looks up to the intellect of its sphere and moves its sphere accordingly. Thus, like .the celestial soul, the practical intellect is the link between intellect as such and matter.
On the whole, Muslim philosophers followed al-Kindi’s division of the theoretical intellect into the material intellect (al-‘aql al-hayulant), the habitual intellect (al-‘agl bil-malaka), the actual intellect (al-‘aql bi’!-fi’b and the acquired intellect’ (al-‘aql al-mustafad). The material intellect is a blank slate with the potentiality for grasping the intelligible forms or universals. Ibn Sina points out that it is referred to as material, not because it is actually material but because it resembles matter in accepting the form. The habitual intellect grasps the universals, as one acquires the skill to write; in other words, this intellect has the ability to use the universals but does not always do so. The actual intellect grasps the universals in actuality and is always ready to use them. While Muslim philosophers differed slightly with regard to their accounts of the acquired intellect, their general view is that it is the highest human state, the point of contact with the divine, the agent intellect (the intelligence of the moon, the lowest celestial intellect), which makes it possible for the theoretical intellect to acquire the universals in the purest form
