Aristotle 19 



Atarneus. Investigation has shown that in the History of 

 Animals there are frequent references to places on the northern 

 and eastern littoral of the Aegean, and especially to localities 

 in the Island of Lesbos ; on the other hand places in Greece 

 proper are but seldom mentioned. 1 Thus his biological 

 investigations, in outline at least, are probably the earliest of 

 his extant works and preceded the philosophical writings which 

 almost certainly date from his second sojourn in Athens. 



In 342 B. c., at the request of Philip of Macedon, Aristotle 

 became tutor to Philip's son, Alexander. He remained in 

 Macedonia for seven years and about 336, when Alexander 

 departed for the invasion of Asia, returned to Athens where 

 he taught at the Lyceum and established his famous school 

 afterwards called the Peripatetic. Most of his works were 

 produced during this the closing period of his life between 335 

 and 323 B. c. After Alexander's death in 323 and the break up 

 of his empire, Aristotle, who was regarded as friendly to the 

 Macedonian power, was placed in a difficult position. Regarded 

 with enmity by the anti-Macedonian party, he withdrew from 

 Athens and died soon after in 322 B. c. at Chalcis in Euboea at 

 about sixty-two years of age. 



The scientific works to which Aristotle's name is attached 

 may be divided into three groups, physical, biological, and 

 psychological. In size they vary from such a large treatise as 

 the History of Animals to the tiny tracts which go to make up 

 the Parva naturalia. So far as the scientific writings can be 

 distinguished as separate works they may be set forth as follows : 



Physics. 



Kpoacris. Physics. 



yere'o-eco? KOI (f)0opas On coming into being and 

 passing away.
