128 SYMBIOSIS 



whole groups of organisms, including man, we may conclude 

 that such a calamity is apt to lead in turn to serious mutual 

 " misunderstandings," to incompatibilities, and even to deadly 

 antagonisms between normal and abnormal classes or races of 

 men. It will be found that the acromegalic class increasingly 

 embraces a philosophy of life akin to one we have lately heard 

 a good deal of, namely, that of the " superman." These 

 " philosophers " will insist on the superiority of their acromegalic 

 instincts and appetites, despising the mentality of the moderate 

 classes as one needing " vertebration." 



I have hinted in Chapter IV. at the danger of a perversion of 

 true thought by bad instincts, ^sop in his fable of the Wolf 

 and the Lamb, seems to have clearly realised already that the 

 Philosophy of the in-feeder is different from, and incompa- 

 tible with, that of the cross-feeder. After all the cross might 

 not be a bad symbol for Biology.
