them is considered indecent in my country. Do the minds of 
all races work in the same fashion, do not their emotions differ

may mar the vision of a single world culture. People are 
genetically and culturally different, and short of a global police 
state run by persons yet to be determined, entrusted with the 
power to perform chromosomal surgery and _ interspecific 
transplants, they will remain different for a long time to come. 
If the world is to become united, the union must be a loose 
confederation of very different units, or it will not long endure.
