Comment and Discussion. xiii 



Again, life on earth is not desirable for those on whom 

 old age has set its insignia of infirmity and deformity with 

 all the attendant daily pains and aches. A natural re- 

 vulsion from life ensues from the senescent condition of 

 the organism. Life grows less and less desirable, until 

 often the aged one longs for release from it. 



This mental attitude touching life is purely the result 

 of the decline of the associate cell life of which the human 

 body is composed. It is to the regeneration of the com- 

 ponent cell life of the organism that our present researches 

 are directed. The object of them is to renovate the tis- 

 sues, renew the cells, and maintain the human body in the 

 adolescent condition : the muscles and digestive organs in 

 a state of noimal health and efBciency, the brain in a con- 

 dition of mental power, hopefulness, and ambition. 



It is not likely that such a person would desire to die, 

 at least, not on an improved and beautified earth where 

 the growth of knowledge and the rapid advances of scien- 

 tific discovery gave opportunity for continuous mental 

 growth. 



But, reverting to our passionate critic, it may be said 

 that Natural Salvation would by no means sentence a man 

 to life. It merely enlarges his freedom to live or not. 

 He does not have to live. In the phrase of firm old 

 Marcus Aurelius, " the open door " is always there, 

 under his hand, with liberty to issue forth to the un- 

 known gods.
