I pursued
To prove the likeness, and if true,
To watch until myself I knew
— from The Other by Edward Thomas

In a world of unyielding chatter, who speaks to you in those rare moments of silence? Whose voice echoes in the solitude? Are you ever unsure if those kindred thoughts or feelings are truly your own? English writer Graham Greene was fascinated by Edward Thomas’ poem “about a man shadowing someone like himself.” In the dense and penetrating narrative The Man Within My Head, author Pico Iyer shadows Greene, deconstructing many of Greene’s most famous works to unravel Iyer’s own story. It is only through accessing Greene — this other — that Iyer can intimately access himself.

Ultimately a meditation on the self in a state of the “foreign alone,” Iyer’s and Greene’s lives parallel, despite a fifty-year age difference, as they each crisscross the globe. Their locations often overlap yet they are separated by time. Both men felt that “life would and could be spent in movement, in process, not settling to any fixity or doctrine, but sensing that the human challenge was something much more profound and unassimilable.” Without the permanence of home, both remained outsiders, distantly observing the interior lives of others.

Iyer understands Greene to be a compassionate writer, one who saw the folly of the individual as complex inevitability; he was “acutely sensitive to all the ways we can fail to understand one another, even those people closest to ourselves.” Greene himself struggled with commitment and a sense of restlessness. He harbored a fear of boredom, which made the concept of internal peace deeply appealing but hypothetical. In examining Greene's works, Iyer becomes fixated on Greene’s The Quiet American, a story that reflects Iyer’s own global curiosity and uncertainty. As he states, it was "like a diagram of the world I knew," depicting the struggle between foolish idealism and seasoned acquiescence.

As Iyer works through his own sense of self via Greene, he finally connects inwardly to his father — another, more subtle voice in his head. Upon discovering one of his own books by his father’s deathbed, Iyer comes to understand there are two kinds of fathers: the ones eternally bound to you and the virtual ones. The former may always possess aspects of mystery — of private identity — but the latter has put it all down on the page, an open book inviting a closer and perhaps conflated interpretation.
