2. Evidently nature possesses neither hands, nor feet, nor any natural or artificial instrument. For production its only need is a matter on which to work, and which it forms. The works of nature exclude all ideas of mechanical operation; not by any impelling force, nor by using levers nor machines does it produce varied colors, nor draw the outlines of objects. Even the workmen who form wax figures, to whose work the operations of nature are often compared, cannot endue objects with colors without borrowing them from elsewhere. Besides, we must observe that these workmen contain a power which remains immutable, and by the sole means of which they produce their works with their hands. Likewise, nature contains a power which remains immovable as a whole; it has no need of some parts that would remain immovable, and others that move. It is matter alone that undergoes movement, for the forming power is in no way moved. Were the forming power moved, it would no longer be the first motor[179]; the first motor would no longer be nature, but whatever might, in its totality, be immovable. NATURE IS IMMOVABLE AS A FORM, BUT NOT AS COMPOUND OF MATTER AND FORM. It may be objected that the ("seminal) reason" may remain immutable, but that nature is distinct from reason, and is mutable. Considering the totality of nature, we include reason. Considering only one of its parts as immutable, this part still will be reason. Nature must be a form, and not a composite of matter and form. What need would it have of a matter that might be either cold or hot, since matter, when subjected to form, either possesses these qualities, or receives them, or rather undergoes the action of reason before having any qualities. Indeed, it is not by fire that matter becomes fire, but by reason. Consequently, in animals and plants, it is the "reasons" that produce[180]; and nature is a reason that produces other reasons, imparting some of herself to the substance subjected to her influence, while remaining within herself. The reason that consists in a visible shape occupies the last rank; it is dead, and produces nothing. The living "reason" (which administers the body of the living being), being sister to the "reason" that produced the visible form (in begetting the body of the living being), and possessing the same power as this reason, alone produces within the begotten being.[181] BOTH NATURE AND REASON ARE CONTEMPLATION; WHILE UNIVERSAL REASON IS BOTH SOUL AND NATURE.
