UNITY IS DIFFICULT TO ASCERTAIN BECAUSE THE SOUL IS FEARFUL OF SUCH ABSTRUSE RESEARCHES.
3. What then is unity? What is its nature? It is not surprising that it is so difficult to say so, when it is difficult to explain of what even essence or form consist. But, nevertheless, forms are the basis of our knowledge. Everything that the soul advances towards what is formless, not being able to understand it because it is indeterminate, and so to speak has not received the impression of a distinctive type, the soul withdraws therefrom, fearing she will meet nonentity. That is why, in the presence of such things she grows troubled, and descends with pleasure. Then, withdrawing therefrom, she, so to speak, lets herself fall till she meets some sense-object, on which she pauses, and recovers; just as the eye which, fatigued by the contemplation of small objects, gladly turns back to large ones. When the soul wishes to see by herself, then seeing only because she is the object that she sees, and, further, being one because she forms but one with this object, she imagines that what she sought has escaped, because she herself is not distinct from the object that she thinks.
