ANAXIMANDER.

ever, the dim notion here of survival or persistence 

 throughout decidedly trying circumstances, which 

 was greatly developed later by Empedocles. In 

 the fragments of Anaximander's teachings we find 

 he does not speculate upon the origin of other land

Grotesque as these ideas of Anaximander are, 

 they indicate a marked advance over the autochtho-

 man grew, like a plant, directly out of the earth ; 

 for we find here an attempt to explain human 

 origin upon the basis of natural analogies. Unfor- 

 tunately, so little knowledge of Anaximander's work 

 is left us, that we can only obtain these vague 

 glimpses of his opinions. ANAXIMENES, his pupil 

 (588-524), found in air the cause of all things. Air, 

 taking the form of the soul, imparts life, motion,

 and water, from which, under the influence of the 

 sun's heat, plants, animals, and human beings were 

 directly produced in the abiogenetic fashion.

 of the Ionian school, also derived both plants and
