PREFACE. xlx 



US, is a chasm that only religion can 

 bridge. From a philosophical point of 

 view, therefore, we must be satisfied if 

 our workable hypotheses in philosophy 

 and in natural science do not contradict 

 each other; and Gustaf Bjorklund has 

 shown us a road to reconciliation be- 

 tween idealism and natural science, that 

 for a long time seemed entirely lost in 

 the jungle of the materialism of the last 

 century. j_ j,. FRIES.
