Context

“Our sense of duty always follows the common and natural course of our passions. To avoid giving offence, I must here observe, that when I deny justice to be a natural virtue, I make use of the word, natural, only as opposed to artificial. In another sense of the word; as no principle of the human mind is more natural than a sense of virtue; so no virtue is more natural than justice. Mankind is an inventive species; and where an invention is obvious and absolutely necessary, it may as properly be said to be natural as any thing that proceeds immediately from original principles, without the intervention of thought or reflection.” source
