_De plant._ i.; 815 a 16. Anaxagoras said that plants are animals and feel pleasure and pain, inferring this because they shed their leaves and let them grow again. _De plant._ i.; 816 b 26. Anaxagoras said that plants have these (motion and sensation) and breathing. _De plant._ i.; 817 a 26. Anaxagoras said that their moisture is from the earth, and on this account he said to Lechineos that the earth is mother of plants, and the sun father. _De X. Z. G._ ii.; 976 b 20. Anaxagoras busying himself on this point, was satisfied with saying that the void does not exist, nevertheless he says beings move, though there is no void. _Meta._ i. 3; 984 a 11. Anaxagoras of Klazomenae, who preceded him (Empedokles) in point of age and followed him in his works, says that the first principles are infinite in number; for nearly all things being made up of like parts (homoeomeries), as for instance fire and water, he says arise and perish only by composition and separation, and there is no other arising and perishing, but they abide eternal. _Meta._ i. 3; 984 b 8. Besides these and similar causes, inasmuch as they are not such as to generate the nature of things, they (again compelled, as we said, by the truth itself) sought the first principle which lay nearest. For perhaps neither fire nor earth nor any other such thing should fittingly be or be thought a cause why some things exist and others arise; nor is it well to assign any such matter to its voluntary motion or to chance. Moreover one who said that as mind exists in animals, so it exists in nature as the cause of the universe and of all order, appeared as a sober man in contrast with those before who spoke rashly. _Meta._ i. 4; 985 a 18. Anaxagoras uses mind as a device by which to construct the universe, and when he is at a loss for the cause why anything necessarily is, then he drags this in, but in other cases he assigns any other cause rather than mind for what comes into being.
