 or to those of thought. It absolutely isolated life, 

 separating it above from the soul, and below from in- 

 animate matter. This sequestration is nowadays 

 much less rigorous. On the psychical side the barrier 

 remains, but it is lowered on the material side. The 

 neo-vitalists of to-day recognize that the laws of 

 physics and chemistry are observed within, as well as 

 without, the living body; the same natural forces' 

 intervene in both, only they are "otherwise directed." 



The vital principle of early times was a kind of
