Every individual is naturally more attached to his own particular order or society, than to any other.

Context

“Some share of the same spirit seems to have descended to the first ministry of Queen Anne. Every independent state is divided into many different orders and societies, each of which has its own particular powers, privileges, and immunities. Every individual is naturally more attached to his own particular order or society, than to any other. His own interest, his own vanity, the interest and vanity of many of his friends and companions, are commonly a good deal connected with it. He is ambitious to extend its privileges and immunities. He is zealous to defend them against the encroachments of every other order or society.” source
