Ahead of America’s 250th Anniversary, Walter Isaacson spotlights one sentence in the Declaration of Independence

Walter Isaacson, the author and biographer known for works spanning technology, science and public life, is turning his attention to one sentence in the Declaration of Independence as Americans prepare for the country’s 250th anniversary. In an interview that aired on PBS NewsHour, Isaacson said the passage he has chosen to emphasize continues to carry weight for modern readers, and he discussed the approach behind his new book, The Greatest Sentence Ever Written.

Judy Woodruff spoke with Isaacson as part of PBS NewsHour’s America at a Crossroads series, which examines issues and themes that the network says will shape public life as the anniversary nears. The conversation focused on how Isaacson reads the Declaration sentence as enduring language, rather than solely as a historical artifact, and why he believes its phrasing matters to present-day debates over civic life.

Isaacson’s book title reflects his central thesis, according to the interview summary: that the Declaration contains a sentence with enough conceptual clarity and emotional force to stand out on its own. Woodruff asked him about what makes that sentence distinctive, and the author tied the line’s structure and meaning to the document’s broader purpose, including its role in establishing authority and grounding the idea of self-government.

While the interview centers on rhetoric and interpretation, it is also framed by the timing of the 250th anniversary, when commemorations and public education efforts often draw renewed attention to foundational texts. PBS NewsHour’s segment situates Isaacson’s project within that seasonal surge in interest, highlighting how cultural institutions, educators, and media outlets may revisit the Declaration’s language as a way to connect past and present.

Isaacson also discussed the audience experience his book aims to create, describing the work as an examination of the sentence’s staying power and what readers can take from it. The author’s emphasis, as presented in the interview, is that the chosen line captures ideas that remain portable, even when the circumstances around them change.

The PBS NewsHour segment did not present the sentence’s full text in the interview description, but it identifies Isaacson’s focus as a single sentence from the Declaration of Independence. As the anniversary approaches, readers interested in how one line can be treated as a lens for civic understanding may look to the book for a more detailed explanation of Isaacson’s reading, and to PBS NewsHour for further installments in its America at a Crossroads series.
