To be a subject is then a property common to matter, to form, and to the combination. But this function of subject is fulfilled differently by matter in respect to form, and by form in respect to the modifications, and by the combination; or rather, matter is not a subject in respect to form; form is the complement which completes it when it still is only matter, and when it exists only potentially.[358] To speak strictly, form is not in matter; for when one thing forms only a unity with something else, one cannot say that one is in the other (as some accident in its subject). Only when both are taken together do matter and form form a subject for other things;[359] thus Man in general, and a particular man constitute the subject of passive modifications; they are anterior to the actions and consequences which relate to them. "Being" therefore is the principle from which all other things derive, and by which they exist; that to which all passive modifications relate, and from which all actions proceed.[360] RELATION BETWEEN PHYSICAL AND INTELLIGIBLE TERMS ARE MERELY VERBAL. 5. Such are the characteristics of sense-being. If in any way they also suit intelligible "being," it is only by analogy,[343] or by figure of speech (homonymy).[361] So, for instance, the "first" is so called in respect of the remainder; for it is not absolutely first, but only in respect to the things which hold an inferior rank; far more, the things which follow the first are also called first in respect to those which follow. Likewise, in speaking of intelligible things, the word "subject" is used in a different sense. It may also be doubted that they suffer ("experience"), and it is evident that if they do suffer, it is in an entirely different manner.[362] PHYSICAL BEING IS THAT WHICH IS NOT IN A SUBJECT.
