Physics

...as inherent; and this is its nature, such that it will exist before it comes to be. For I define matter as the primary subject for each thing, from which something comes to be as an inherent part, and not coincidentally. If it is destroyed, it will arrive at this as its final state, such that it will have been destroyed before it is destroyed. Regarding the principle according to the form, whether it is one or many, and who or what they are, it is the task of first philosophy Aristotle refers here to what would later be termed "metaphysics." to determine it; therefore, let it be set aside for that time. We shall speak of natural and perishable forms in later demonstrations. Thus, let it be determined by us that there are principles, what they are, and how many they are in number; but let us begin again and define another principle.

Of things that exist, some exist by nature, others by other causes. By nature, we say, exist animals and their parts, plants, and simple bodies, such as earth, fire, water, and air original: "ταῦτα γὰρ εἶναι καὶ τὰ τοιαῦτα φύσει φαμέν" (for we say that these and suchlike exist by nature). All the aforementioned appear to differ from those things not constituted by nature. For each of these has within itself a principle of motion and rest, some in respect to place, others in respect to growth and decay, and others in respect to alteration. But a bed, a cloak, and any other such kind—insofar as each has attained such a classification, and insofar as it is a product of craft techne art/craft/skill—has no innate impulse of change. Yet, insofar as it happens that they are made of stone, earth, or a mixture of these, they do have it, and to that extent, as if nature were...

Critical apparatus in Latin and Greek:
30 "itself" in one codex of Bekker and Simplicius (lemmata) and Bonitz. "itself" codex E and others. — 192ᵇ 1 "perishable" / "of perishable things" others. — 9 "and we say it is" / "indeed" others. — 11 "water and air" / "air and water" others. These "and suchlike... we say" are to be excised, since we follow codex E in the preceding. — 13 "of these — has" / "for all things that exist by nature appear to have in themselves a principle" others. — 18 "impulse" / "principle" Simplicius (variant reading).
