Francis Galton once said in his Natural Inheritance, 1890:
It is difficult to understand why statisticians commonly limit their inquiries to Averages and do not revel in more comprehensive views. Their souls seem as dull to the charm of variety as that of a native of one of our flat English counties, whose retrospect of Switzerland was that, if the mountains could be thrown into its lakes, two nuisances would be got rid of at once.
Even though I have looked up and understood every single word, I still cannot get the meaning of the bolded part. Any ideas?
