What is the author's style in A Theory of Justice by John Rawls?

Rawls puts forth his argument in the narrative voice of both the first person singular—meaning that he uses the pronoun "I" to indicate the source of his ideas—and the first person plural—meaning that he also uses the pronoun "we" to express his ideas. This choice may be contrasted with an approach that assumes an objective, or third-person voice by which to put forth a philosophical argument. Rawls appropriately chooses the first person singular narrative voice, which allows him to articulate his ideas in the style of an individual working out a complex, admittedly imperfect, sometimes provisional, philosophy—rather than the definitive, objective conclusions of a third person omniscient (all-knowing) narrator. Although Rawls argues in philosophical abstractions, his use of the first person "I" is a means of presenting his ideas as the result of an ongoing thought process.
