OBJECT AND LIVING ORGANISM 125 



Finally, we have been able to demonstrate that the 

 impulse-sequence also controls the activity of protoplasm, 

 and thus shows itself to be an independent natural force, 

 producing organs with differentiated framework, and then 

 causing them to disappear again. Once the framework is 

 there, the activity can proceed automatically within its 

 limits. 



But since the framework is constructed by the impulse- 

 sequence in conformity with plan, its action in the outer 

 world is both in accordance with plan and also automatic. 



The question concerning the conformity with plan is the 

 business of biology ; the question concerning the mechanical 

 running belongs to physiology.
