In it there are those particles which are producers of blood, bones, nerves, and all other parts; these particles (he thought) reason discovers for us.

For it is not necessary that we should reduce all things under the objects of sense; for bread and water are fitted to the senses, yet in them there are those particles latent which are discoverable only by reason.

Matter is according to him these similar parts, and the efficient cause is a Mind, which orders all things that have an existence.
