Question

For Aristotle, why did he say that man by nature is a political animal? How is this construed in the social dimension of the interpersonal? 

Answer 1

Historically and currently, unless you are a feral child!! you are born into the society of your family and that family is among the society of other families. The so-called "state of nature is fiction. In the event you were consciously anti-social you would still need the help of the doctor and farmer and other laborers.

Whosoever is delighted in solitude is either a wild beast or a god.

Aristotle

A person is an inter-relational being in most modern philosophies. Look up "personalism"
