What is a human being? How do you explain human nature?
There are many kinds of beings: animals, vegetables, minerals, etc. Anything that exists is a being. What kind of a being is a human being? What aspects of existence do humans have in common? What attributes or traits or characteristics do we share with one another that make it possible to distinguish humans as a category of being different from all other categories of being? Do human beings engage in a broad variety of activities not found in other species?
