"Between vitalism and mechani sm there is a middle 

 ground which may be called 'Organizationism' or 'Emergence', 

 which holds that life, differential sensitivity and reactiv- 

 ity, fitness and psychic phenomena, are results of increas- 

 ing organization, these properties 'emerging' as it were, 

 by a process of creative synthe s is .
