 In the later (post 1260) Communia naturalium, Bacon gives six meanings for the concept of matter. (1) Matter is the subject of action as when we say that wood is the matter for the action of the carpenter. (2) In the proper sense of the term, matter is that which, with form, constitutes the composite, as in the case of every created substance. (3) Matter is the subject of generation and corruption and has the property of being an incomplete and imperfect thing in potency to being a complete thing. (4) Matter is the subject of alteration since it receives contrary accidents. (5) Matter can be considered as an individual in relation to the universal, the latter being founded in its individual as in a material principle. (6) Matter is the name for that which is gross, as when we say that earth has more matter than fire (Sharp 1930, 127–151).
