Use the following quotation from Karl Pearson's "National Life from the Standpoint of Science" to answer this
question and the one following:
"There is a struggle of race against race and of nation against nation. In the early days of that struggle it was a
blind, unconscious struggle of barbaric tribes. At the present day, in the case of the civilized white man, it has
become more and more the conscious, carefully directed attempt of the nation to fit itself to a continuously
changing environment."
How is this source an example of scientific racism?
