40 AMONG THE CREEKS. 



of thej^tiiesi, or of Natural Selection. And the 

 absolute proof that Empedocles' crude hypothesis 

 embodied this world famous thought, is found in 

 passages in Aristotle's Physics, in which he refers

 mind of Aristotle, was stated precisely in its modern 

 form, as we shall see later in our study of Aristotle. 

 Lange attributes to Democritus a similar inter-

 " attainment of adaptations through the infinitely 

 repeated play of production and annihilation, in 

 which finally that alone survives which bears the 

 guarantee of persistence through its relatively

 conservative and sounder view of the real meaning 

 of this old philosopher of Agrigentum. He says 

 this could not have been advanced by Empedocles 

 as an explanation of Design in Nature, because 

 this idea had not yet been formulated in the 

 Greek mind.
