 day, by Eudolf Wagner himself, in an address which 

 he delivered at the meeting of the German Association 

 of Sciences, which took place at Gottingen in the year 

 1854. The challenge which was thus thrown out was 

 taken up by Karl Vogt, 1 who, in various pamphlets 

 and by characteristic phrases, stigmatised the position 

 as dualistic and untenable, spoke of the genuine 

 Gottingen Seelensubstanz, and opened the long campaign 

 which goes under the name of the materialistic con-

 took part. It resulted in an enormous popular litera-

 school played a great part, being, if not really more 

 intelligible, still seemingly more easily assimilated by 

 the popular mind. In many instances they allied them-

 material prosperity of the German nation, which they 

 supplied with a shallow but convenient creed.
