386 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1945 



had carried the human experiment, through trial and error, to a level 

 which must command the admiration of all discerning men ; a people 

 who, but for a natural calamity with which they could not cope, and 

 because of the rapacity of unscrupulous and hostile neighbors, might 

 have borne the torch of civilization to undreamed-of heights. The 

 construction of a million-dollar irrigation system, representing a 

 high degree of engineering skill, attests to their energy, strength, 

 courage, and initiative. 



Our culture of today is complex, while theirs was simple ; but who 

 would venture to say that ours is "higher" or better? We, as were 

 they, are still beset with the threat of natural calamity, and by "man's 

 inhumanity to man." The first of these is nothing as compared to 

 the latter, which precipitated all mankind into a holocaust such as 

 the world never has known, the aftermath of which conceivably 

 might be more disastrous than the titanic struggle itself. 



The only criterion which justifies an assumption that one culture 

 is higher or better than another, is proof that it provides a larger 

 measure of cooperation, usefulness, spirituality, morality — and 

 human happiness !
