If we would know why the same body seems greater, without adding to it, one time than another, they say, when it seems less, it is “condensed”; when greater, “rarified.” What is that “condensed,” and “rarified?” Condensed is when there is in the very same matter, less quantity than before, and rarified, when more. As if there could be matter that had not some determined quantity; when quantity is nothing else but the determination of matter; that is to say, of body, by which we say, one body is greater or lesser than another, by thus or thus much. Or as if a body were made without any quantity at all, and that afterwards more or less were put into it, according as it is intended the body should be more or less dense.

For the cause of the soul of man, they say, creatur infundendo , and creando infunditur : that is, “it is created by pouring it in,” and “poured in by creation.”
