<human>:  Why did Hannah Arendt write the book ‘The Human Condition’?
<bot>: The Human Condition is a book about the nature of human beings. Arendt argues that humans are not merely animals, but are also rational beings with the capacity for free will. She argues that humans are unique in that they are the only species that can choose to act in a way that is contrary to their own self-interest. This is what makes humans different from other animals, and it is what makes humans unique.
