ii. 4; 196 a 20. Empedokles says that the air is not always separated upwards, but as it happens. viii. 1; 250 b 27. Empedokles says that things are in motion part of the time and again they are at rest; they are in motion when Love tends to make one out of many, or Strife tends to make many out of one, and in the intervening time they are at rest (Vv. 69-73). viii. 1; 252 a 6. So it is necessary to consider this (motion) a first principle, which it seems Empedokles means in saying that of necessity Love and Strife control things and move them part of the time, and that they are at rest during the intervening time. _De Caelo_ 279 b 14. Some say that alternately at one time there is coming into being, at another time there is perishing, and that this always continues to be the case; so say Empedokles of Agrigentum and Herakleitos of Ephesus. ii. 1; 284 a 24. Neither can we assume that it is after this manner nor that, getting a slower motion than its own downward momentum on account of rotation, it still is preserved so long a time, as Empedokles says. ii. 13; 295 a 15. But they seek the cause why it remains, and some say after this manner, that its breadth or size is the cause; but others, as Empedokles, that the movement of the heavens revolving in a circle and moving more slowly, hinders the motion of the earth, like water in vessels.... iii. 2; 301 a 14. It is not right to make genesis take place out of what is separated and in motion. Wherefore Empedokles passes over genesis in the case of Love; for he could not put the heaven together preparing it out of parts that had been separated, and making the combination by means of Love; for the order of the elements has been established out of parts that had been separated, so that necessarily it arose out of what is one and compounded. iii. 2; 302 a 28. Empedokles says that fire and earth and associated elements are the elements of bodies, and that all things are composed of these. iii. 6; 305 a 1. But if separation shall in some way be stopped, either the body in which it is stopped will be indivisible, or being separable it is one that will never be divided, as Empedokles seems to mean. iv. 2; 309 a 19. Some who deny that a void exists, do not define carefully light and heavy, as Anaxagoras and Empedokles. _Gen. corr._ i. 1; 314 b 7. Wherefore Empedokles speaks after this manner, saying that nothing comes into being, but there is only mixture and separation of the mixed. i. 1; 315 a 3. Empedokles seemed both to contradict things as they appear, and to contradict himself. For at one time he says that no one of the elements arises from another, but that all other things arise from these; and at another time he brings all of nature together into one, except Strife, and says that each thing arises from the one.
