CHAPTER XIX 



MATTER AND " MIKD-STUFF " 



Conclusions — E6sum6 of what has been said — Biogen is matter 

 in process of becoming or being transformed from free elec-

 nature of physical metabolism — Matter a mode of motion — 

 Motion a • complex perception or mode of thought — Two 

 modes of thought, our own minds and matter are concomi-

 Their respective positions — Mind-stuff, how reconciled with

 of the process of evolution in the totality of 

 things : organic and inorganic, physical and mental.
