| In this paper, I shall be discussing two topics: firstly, whether Theophrastus followed Aristotle in holding that the heavens were made of a substance—the ether—distinct from the four sublunary elements, or whether, as some have argued, he held that the heavens were made of fire; and secondly, the exact interpretation of certain technical terms of astronomy attributed to Theophrastus. I am throughout indebted to the work of my colleagues in Project Theophrastus, and especially to Professor William Fortenbaugh and Mrs. Pamela Huby. It was an interest in the Peripatetic tradition generally that led me to work on Theophrastus, and that interest has been both formed and stimulated by the works of Professor Paul Moraux; the theme of the present paper is one that he has himself discussed.

| At the beginning of his Corollary on Place (In Phys. 601, 14-24), Simplicius classifies theories about place, as follows. First, there is a distinction between those who make place a corporeal thing and those who suppose it is incorporeal. Only Proclus falls into the first class. O f the latter, some think it is without extension, the rest think it is extended. The first group consists of Plato, who said place is the material substrate of bodies, and Damascius, who said it is that which completes the nature of bodies. The second group is further subdivided, into those who held place to be extended in two dimen sions, “as Aristotle and the whole Peripatos did”, and those who gave it three dimensions. The latter can be subdivided again: on the one hand, there is the school of Democritus and Epicurus, who held that place is everywhere undifferentiated, and sometimes persists without any body in it, and on the other hand, “the famous Plato- nists and Strato of Lampsacus”, who said that place is an extended interval (diastema) that always contains body and is adapted to its particular occupant...

| Aristotle’s conception of identity is too large a subject to be analyzed in a single article. I will try to discuss here just one of the many problems raised by his views on sameness. It is not, perhaps, the most stimulating question one could wish to see treated, but it is a question about logic, where I feel a little more at ease than among the complicated and obscure riddles of metaphysics. My subject will be Aristotle’s references to what is nowadays called ‘Leibniz’s Law’ (LL): if two objects x and y are the same, they both share all the same properties. A formal version of it could be: (1) x=y ⟹ ∀F(F(x) ⟺ F(y))x=y⟹∀F(F(x)⟺F(y)) It is perhaps worth remembering that (LL) must be distinguished from what is normally called the ‘principle of substitutivity’ (SP), according to which substitution of expressions that are said to be the same is truth-preserving. As has been shown, (LL) does not entail (SP), since there are counterexamples to (SP) that do not falsify (LL). Not only (SP), but also (LL) has been doubted by some modern logicians. The question is far from being settled, and it is perhaps of interest to examine how ancient logicians tried to manage this problem. First, I will consider Aristotle’s statements about (LL) and the analyses he gives of some supposed counterexamples to this principle. Secondly, the interpretations of his view among his Greek commentators will be taken into account, and their distance from the position of the master evaluated. As Professor Moraux has taught us, the study of the Aristotelian tradition often gives us the opportunity of understanding Aristotle’s own meaning better. [introduction p. 57-58] |

It is not, perhaps, the most stimulating question one could wish to see treated, but it is a question about logic, where I feel a little more at ease than among the complicated and obscure riddles of metaphysics.

A formal version of it could be:
(1) x=y ⟹ ∀F(F(x) ⟺ F(y))x=y⟹∀F(F(x)⟺F(y))
It is perhaps worth remembering that (LL) must be distinguished from what is normally called the ‘principle of substitutivity’ (SP), according to which substitution of expressions that are said to be the same is truth-preserving. As has been shown, (LL) does not entail (SP), since there are counterexamples to (SP) that do not falsify (LL). Not only (SP), but also (LL) has been doubted by some modern logicians. The question is far from being settled, and it is perhaps of interest to examine how ancient logicians tried to manage this problem.
First, I will consider Aristotle’s statements about (LL) and the analyses he gives of some supposed counterexamples to this principle. Secondly, the interpretations of his view among his Greek commentators will be taken into account, and their distance from the position of the master evaluated. As Professor Moraux has taught us, the study of the Aristotelian tradition often gives us the opportunity of understanding Aristotle’s own meaning better. [introduction p. 57-58] |

I will try to discuss here just one of the many problems raised by his views on sameness.

At the beginning of his Corollary on Place (In Phys. 601, 14-24), Simplicius classifies theories about place, as follows. First, there is a distinction between those who make place a corporeal thing and those who suppose it is incorporeal. Only Proclus falls into the first class. O f the latter, some think it is without extension, the rest think it is extended. The first group consists of Plato, who said place is the material substrate of bodies, and Damascius, who said it is that which completes the nature of bodies. The second group is further subdivided, into those who held place to be extended in two dimen sions, “as Aristotle and the whole Peripatos did”, and those who gave it three dimensions. The latter can be subdivided again: on the one hand, there is the school of Democritus and Epicurus, who held that place is everywhere undifferentiated, and sometimes persists without any body in it, and on the other hand, “the famous Plato- nists and Strato of Lampsacus”, who said that place is an extended interval (diastema) that always contains body and is adapted to its particular occupant...

In this paper, I shall be discussing two topics: firstly, whether Theophrastus followed Aristotle in holding that the heavens were made of a substance—the ether—distinct from the four sublunary elements, or whether, as some have argued, he held that the heavens were made of fire; and secondly, the exact interpretation of certain technical terms of astronomy attributed to Theophrastus. I am throughout indebted to the work of my colleagues in Project Theophrastus, and especially to Professor William Fortenbaugh and Mrs. Pamela Huby. It was an interest in the Peripatetic tradition generally that led me to work on Theophrastus, and that interest has been both formed and stimulated by the works of Professor Paul Moraux; the theme of the present paper is one that he has himself discussed.
