MAN. THE INSTINCT OF LIFE AND DEATH. 359 



improved, will be the work of time and science. 

 Realized at last it will serve as a solid basis for 

 individual, family, and social morality. Healthy 

 youth fit for action; prolonged, adult age, the 

 symbol of strength ; normal old age, wise in council, 

 these would have their natural places in harmonious

 premature, deformed, incapable and egoistic old age 

 which results from a pathological condition. At the 

 end of this full life, the old man being full of days, 

 will crave for the eternal sleep and will resign 

 himself to it with joy. . . . 



Death, then, " the last enemy that shall be 

 destroyed," to use the expression of St. Paul, will 

 yield to the power of science. Instead of being 

 " the king of terrors," it will become after a long 

 and healthy life, after a life exempt from morbid 

 accidents, a natural and longed for event, a satisfied 

 need. Then will be realized the wish of the 

 fabulist : 



"I should like to leave life at this age, fust as one 

 leaves a banquet, thanking the host, and departing."

 of death supervening at the end of a normal and 

 well-fHled cycle will no doubt facilitate to the aged 

 their departure on the great voyage. The wrench
