"Chez tous les etres vivants le milieu inter ieur qui 

 est un produit de I'organisme, conserve les rapporte neces- 

 saires d'echange avec le milieu exterieur; mais a mesure que 

 I'organisme devient plus parfait, le milieu organique se 

 specific et s'isole en quelque sorte de plus en plus du 



milieu amb iant . 



Claude Bernard 1885 



"A graduate from one of our larger universities, when 

 asked why he changed from Biology to Philosophy said: 'Well. 

 I found that there was so much. to be learned in Biology that 

 I had no time to think, so I took up Philosophy, where there 

 is nothing to be learned and J had all my time to think.'"
