PERIOD III. 



thirty-six volumes crowded with plates. Having- won 

 for himself a place side by side with Montesquieu and 

 Gibbon, he employed it to direct attention to the larger 

 questions of biology and geology. He was a pro- 

 nounced freethinker, who promulgated bold views with 

 a dexterity which saved him from condemnation by the 

 theological tribunals. When his opinions were declared 

 to be contrary to the teaching of the Church, he printed 

 a conciliatory explanation, but never cancelled the 

 passages objected to, which continued to appear in a

 brought him under the sarcastic remark of Fontenelle, 

 that ignorance is less apparent when it fails to explain 

 'what is, than when it undertakes to explain what is not. 



Buffon's fame is not seriously impaired by the fact 

 that his great work is no long-er read except by those 

 who study the course of scientific thought. Few 

 productions of the human intellect retain their value 

 after a hundred years, and scientific treatises become 

 obsolete sooner than others. It is consoling- to 

 recollect that, if their energy is quickly dissipated, it is 

 at least converted into light. 



In a history of biology Buffon is naturally a more 

 important figure than Montesquieu. Buffon had im- 

 bibed evolutionary views from the Protogcea of Leibnitz, 

 which in turn made use of certain hypotheses of
