of matter.

matter is that first being which is substrate for generation, corruption, and all other alterations.

the disciples of thales and pythagoras, with the stoics, are of opinion that matter is changeable, mutable, convertible, and sliding through all things.

the followers of democritus aver that the vacuum, the atom, and the incorporeal substance are the first beings, and not obnoxious to passions.

aristotle and plato affirm that matter is of that species which is corporeal, void of any form, species, figure, and quality, but apt to receive all forms, that she may be the nurse, the mother, and origin of all other beings. but they that do say that water, earth, air, and fire are matter do likewise say that matter cannot be without form, but conclude it is a body; but they that say that individual particles and atoms are matter do say that matter is without form.
