GENERATION ILLUSTRATED BY LIGHTING FIRE BY REFRACTION.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
If matter participated in the existence of genuine beings and received them within itself, as might easily be thought, that which would enter into it would penetrate deeply into matter; but evidently matter is not penetrated thereby, remaining unreceptive of any of it. On the contrary, matter arrests their "procession," as echo arrests and reflects sound-waves, matter being only the "residence" (or, "jar" or vase) of the things that enter within it, and there mingle with each other. Everything takes place there as in the case of persons who, wishing to light fire from the rays of the sun, should place in front of these rays polished jars filled with water, so that the flame, arrested by the obstacles met within, should not be able to penetrate, and should concentrate on their outside. That is how matter becomes the cause of generation; that is how things occur within it.
