In paragraph 4, what reasons does Justice Thurgood Marshall give for his view that the first three words of the Preamble are evidence "of the evolving nature of the Constitution"?

Justice Thurgood Marshall looks at the first three words, "We the people," as evidence that the Constitution is not static and is, in fact, developing/changing with the times. For instance, Justice Thurgood Marshall says that "We the people" did not actually mean everybody when it was written. The words "We the people" actually excluded African Americans, Native Americans, women, and even whites if they did not own land. However, the words "We the people" eventually evolved to mean all United States citizens regardless of heritage, gender, class, etc. Thus, this is evidence that the Constitution evolves with time with the nature of the nation for which it was written.
