It is the most famous poem in American literature, a staple of pop songs, newspaper columnists and valedictorian speeches. It is “The Road Not Taken” by Robert Frost:



Everyone can quote those final two lines. But everyone, writes David Orr in his new book “The Road Not Taken” (Penguin Press), gets the meaning wrong.

The poem is praised as an ode of individuality, to not follow the pack even though the path may be more difficult.

Except Frost notes early in the poem that the two roads were “worn . . . really about the same.” There is no difference. It’s only later, when the narrator recounts this moment, that he says he took the road less traveled.

“This is the kind of claim we make when we want to comfort or blame ourselves by assuming that our current position is the product of our own choices (as opposed to what was chosen for us, or allotted to us by chance),” Orr writes.

“The poem isn’t a salute to can-do individualism,” he continues. “It’s a commentary on the self-deception we practice when constructing the story of our own lives.”

Wrongly referred to by many as “The Road Less Traveled,” the poem’s true title, “The Road Not Taken,” references regret rather than pride. That’s by design. Frost wrote it as somewhat of a joke to a friend, English poet Edward Thomas.

In 1912, Frost was nearly 40 and frustrated by his lack of success in the United States. After Thomas praised his work in London, the two became friends, and Frost visited him in Gloucestershire. They often took walks in the woods, and Frost was amused that Thomas always said another path might have been better. “Frost equated [it] with the romantic predisposition for ‘crying over what might have been,’ ” Orr writes, quoting Frost biographer Lawrance Thompson.

Frost thought his friend “would take the poem as a gentle joke and protest, ‘Stop teasing me,’ ” Thompson writes.

He didn’t. Like readers today, Thomas was confused by it and maybe even thought he was being lampooned.

One Edward Thomas biographer suggested that “The Road Not Taken” goaded the British poet, who was indecisive about joining the army.

“It pricked at his confidence . . . the one man who understood his indecisiveness most acutely — in particular, toward the war — appeared to be mocking him for it,” writes Matthew Hollis.

Thomas enlisted in World War I, and was killed two years later.

Orr writes that “The Road Not Taken” is “a thoroughly American poem. The ideas that [it] holds in tension — the notion of choice, the possibility of self-deception — are concepts that define . . . the United States.”

It is also, as critic Frank Lentricchia writes, “the best example in all of American poetry of a wolf in sheep’s clothing.”
