in NAME_1 (NAME_2), there is the concept of differentiating between humans and "animals". The books deeply explore what it means to be human. It seems that the bene gesserit certainly had a very specific set of criteria in mind in the first book. Later, NAME_3 NAME_4 seemed to adhere a broader definition of what it means to be human. Do you agree? Can you please infer what their definition  of a "human" and "animal" could be? Use some words in all caps in your response, but those all-caps words should appear at most 5 times.
