After the first paragraph of the first essay of On the Genealogy of Morals, Nietzsche discusses how English psychologists may be motivated to study the darker side of "our inner world". Then he stated the following:
But I am told that it is simply a case of old frigid and tedious frogs crawling and hopping around men and inside men, as if they were as thoroughly at home there, as they would be in a swamp.
What does this analogy entail? Is Nietzsche saying that people have likened undesirable traits to frogs, with men being the swamp?
