HALLER AND LEIBNITZ. 39 



(j}fulla est epigenesis). No part of the animal body was made 

 previous to another, and all were created simultaneously 

 {Nulla in corpore animali loars ante aliam facta est, 

 et omnes shnid creatce existunt)." In reality, therefore, 

 he denied any actual evolution in the natural sense, and 

 in this went so far as to maintain even the existence of a 

 beard in the new-born boy, and the existence of the horns 

 in the hornless fawn ; all the parts were already present 

 in a complete state, but hidden for a while from the human

 advocated all this rampant nonsense, and the inferences 

 drawn from it, most successfully, even after Wolff had dis- 

 covered the true Epigenesis, and proved it by investigation. 

 Leibnitz was the most important of the philosophers 

 who adopted the Theory of Evolution (Pre-formation), and 

 by his great authority, as well as by his talented exposition, 

 gained numerous followers for it. Based upon his Theory 

 of IiEonads, according to which soul and body are in an 

 eternally inseparable union, and in their bi-unity constitute

 Theodicce, for instance, he says : " I think that souls, which 

 will some day be human souls, as in the case of those of
