In his writing, Amitav Ghosh is by turns a rescue worker, a philanthropist, a liaison, and a confidante. But these varied hats, in the end, are incidental—in fact, secondary—to the one simple role that the author, through his thoughtful gaze, has elevated to an art: that of the observer.

Throughout this collection of essays, Ghosh takes us from the desolation of subcontinental peaks to the harried crowds of downtown Brooklyn. His writing flows from what he sees: whatever presses on the people that surround him. A tsunami's destruction on the Andaman and Nicobar islands, the brain cancer of a close friend, the fierce pride of an Egyptian imam—these are the pressures that guide his pen. Ghosh navigates us through the small struggles that make up, as the title suggests, "the turmoil of our times." He knows that these observations, at the barest level, are nothing more than sparse collections of facts, numbers, and dates. In "The Ghat of the Only World," Ghosh recounts by date and time his conversations with the poet Agha Shahid Ali during the last years of his life. Yet as these episodes accumulate, the skeletal facts of the writing—what we normally think of as journalism —form the foundation for an aching, eloquent portrait of a dying artist. Ghosh does not wax sentimental; indeed, in many ways, he seems merely to report. Only the author's remarkable intuition for his subjects—his ability to convey whole histories with a few delicately phrased sentences—gives these essays their urgency.

Ghosh tells us that Shahid, the dying poet, was an audacious writer, fearlessly proclaiming lines like, "Mad heart, be brave." Ghosh is not such a writer; his strength is a quiet one. Much of the prose here operates with fine lines: although many of his essays are driven by larger, implicit ideals, the words themselves stick to concrete specifics, to details. He captures the vast heat of the Indian desert by describing the wind that "chafed like sandpaper" against his eyes.

This sharp, careful prose becomes especially powerful when Ghosh turns his attention to political affairs, matters quite literally of life and death. Much of the writing here centers around the Middle East and the subcontinent. In one sense, the focus comes naturally for Ghosh because these places have shaped his life: a native of Calcutta, he spent his childhood in Bangladesh and Sri Lanka. But this region also contains a bundle of tensions yet to be released, and it is anyone's guess whether this release will foment renaissance or ruin.

Ghosh explores these tensions in his essay "Countdown," which was written during India 's and Pakistan 's nuclear tests in 1998. As Ghosh evaluates the mounting pressure, he does not dramatize, nor does he flinch: "There are, in fact, many reasons to fear nuclear catastrophe in South Asia." He talks with everyone from foot soldiers in Kashmir to government officials in New Delhi and subtly adds his own quiet beliefs, speaking for "those such as myself, people who were opposed to nuclear armaments in an instinctive, perhaps unreflective way." The phrasing is self-deprecating, but the conviction behind it is rock-solid. Beneath all the even-handed evaluation and careful investigation, Ghosh's writing is based on an unshakable foundation of what can only be called morality.

This quiet strength seems only appropriate for the author's observational role. Ghosh is aware of this and reflects freely on his own perception of the writer's place in history and society. Some of the book's strongest essays deal directly with problems of literature and politics: how other authors and other observers interpret their world, and how the world in turn reacts to their visions. In such reflections, the power of the writer—for better or for worse—becomes evident: Ghosh gives the sobering example of Taslima Nasrin, a Bangladeshi novelist whose novel Lojja, a chronicle of one Hindu family struggling against persecution, ultimately became appropriated by Hindu supremacist propaganda. The point is clear: we all, as we lead our daily lives, intersect and speak to one another. There is a danger in being misunderstood, but there is also the possibility, the hope, that our voices, no matter how small, will be heard.

This implicit optimism illuminates what could easily have been a relentlessly dark collection of writing. The subjects that Ghosh takes on are meant to comment on the uneasy atmosphere of change that dominates much of the world. No one is quite sure where we are going or what the next day will bring. Yet as we go through our daily struggles, the documents that our lives leave in their wake—like Ghosh's essays—allow us to look back on where we have been and how we have traveled from there to here. And from this sense of the past, Ghosh suggests, derives the material that shapes our future.
