Preface 



This small volume is in form controversial, 

 but in substance it has a more ambitious 

 aim : it is intended to formulate, or 

 perhaps rather to reformulate, a certain 

 doctrine concerning the nature of man 

 and the interaction between mind and 

 matter. Incidentally it attempts to confute 

 two errors which are rather prevalent : 



i. The notion that because material 

 energy is constant in quantity, 

 therefore its transformations and 

 transferences which admittedly 

 constitute terrestrial activity are 

 not susceptible of guidance or 

 directive control.
