For there is no relation or comparison whatever between corporeal and incorporeal beings, neither in the moment of action nor in that of inaction. It is only by homonymity that the term "action" is used in reference to the forms residing in bodies, and also in reference to absolutely spiritual beings. The circumstance that a purely spiritual being does not effect at one time that which it effects at another, does not necessitate a transition from potentiality to actuality: such a transition is necessary in the case of forces connected with bodies. It might, perhaps, be objected that our argument is, to some extent, a fallacy; since it is not due to anything contained in the Active Intellect itself, but to the absence of substances sufficiently prepared for its action, that at times it does not act: it does act always when substances sufficiently prepared are present, and, when the action does not continue, it is owing to the absence of substance sufficiently prepared, and not to any change in the Intellect. I answer that it is not our intention to state the reason why God created at one time and not at another: and, in referring to the Active Intellect as a parallel, we do not mean to assert that God acts at one time and not at another, in the same manner as the Active Intellect, an absolutely spiritual being, acts intermittently. We do not make this assertion, and, if we did, the conclusion would be fallacious. What we infer, and what we are justified in inferring, is this: the Active Intellect is neither a corporeal object nor a force residing in a body: it acts intermittently, and yet whatever the cause may be why it does not always act, we do not say that the Active Intellect has passed from a state of potentiality to that of actuality: or that it implies the possibility [of change], or that an agent must exist that causes the transition from potentiality to actuality. We have thus refuted the strong objection raised by those who believe in the Eternity of the Universe: since we believe that God is neither a corporeal body nor a force residing in a body, we need not assume that the Creation, after a period of inaction, is due to a change in the Creator Himself.
The second method employed in proving the Eternity of the Universe is based on the theory that all wants, changes, and obstacles are absent from the Essence of God. Our refutation of this proof, which is both difficult and profound, is this. Every being that is endowed with free will and performs certain acts in reference to another being, necessarily interrupts those acts at one time or another, in consequence of some obstacles or changes. E.g., a person desires to have a house, but he does not build one, because he meets with some obstacles: he has not the material, or he has the material, but it is not prepared for the purpose on account of the absence of proper instruments; or he has material and instruments, and yet does not build a house, because he does not desire to build it: since he feels no want for a refuge. When changed circumstances, as heat or cold, impel him to seek a refuge, then he desires to build a house. Thus changed circumstances change his will, and the will, when it meets with obstacles, is not carried into effect. This, however, is only the case when the causes of the actions are external: but when the action has no other purpose whatever than to fulfil the will, then the will does not depend on the existence of favourable circumstances. The being endowed with this will need not act continually even in the absence of all obstacles, because there does not exist anything for the
