96 MARXISM AND DARWINISM. 



plicable in the other domain? In practice it is very 

 convenient to have one principle for the human world 

 and another one for the animal world. In having this, 

 however, we forget that man is also an animal. Man 

 has developed from an animal, and the laws that ap- 

 ply to the animal world cannot suddenly lose their 

 applicability to man. It is true that man is a very 

 peculiar animal, but if that is the case it is necessary 

 to find from these very peculiarities why those prin- 

 ciples applicable to all animals do not apply to men, 

 and why they assume a different form. 



Here we come to another grave problem. The 

 bourgeois Darwinists do not encounter such a prob- 

 lem; they simply declare that man is an animal, and 

 without further ado they set about to apply the Dar- 

 winian principles to men. We have seen to what 

 erroneous conclusions they come. To us this ques- 

 tion is not so simple ; we must first be clear about the 

 differences between men and animals, and then we can 

 see why, in the human world, the Darwinian principles 

 change into different ones, namely, into Marxism. 



VII. THE SOCIABILITY OF MAN. 



The first peculiarity that we observe in man is 

 that he is a social being. In this he does not differ 

 from all animals, for even among the latter there are 

 many species that live socially among themselves. But 

 man differs from all those that we have observed until 

 now in dealing with the Darwinian theory ; he differs 

 from those animals that do not live socially, but that 

 struggle with each other for subsistence. It is not 

 with the rapacious animals which live separately that
