agitated the opponent down to the most secret folds 

 of his philosophy, the usual consequences did not 

 fail to put in an appearance. Haeckel was branded

 in the History of Creation there is the danger 

 involved in the popular presentation of the results 

 of scientific research. Any man who has written 

 popular works, or delivered lectures to the general 

 public, knows what this means. There is little 

 common measure between them. The truths of 

 science are in a state of constant flux ; it is of their 

 essence to be so. To fish out a piece from this 

 stream, fix it, and magnify it for the public with a 

 broad beam of light, really amounts in principle to 

 an alteration of it ; it is putting a certain pressure 

 on things, and giving them an arbitrary shape. 

 The work of popularising truths is so holy a thing 

 in its aim that this risk has to be run. We must 

 take things as they are. We have two alternatives: 

 either not to popularise at all, or to take the 

 apparatus with all its defects. We can diminish
