Drawing on seven years of his own research and the work of other esteemed Lincoln scholars, Shenk reveals how the sixteenth president harnessed his depression to fuel his astonishing success.
Lincoln found the solace and tactics he needed to deal with the nation’s worst crisis in the “coping strategies” he had developed over a lifetime of persevering through depressive episodes and personal tragedies.

With empathy and authority gained from his own experience with depression, Shenk crafts a nuanced, revelatory account of Lincoln and his legacy. Based on careful, intrepid research, Lincoln’s Melancholy unveils a wholly new perspective on how our greatest president brought America through its greatest turmoil.

Shenk relates Lincoln’s symptoms, including mood swings and at least two major breakdowns, and offers compelling evidence of the evolution of his disease, from “major depression” in his twenties and thirties to “chronic depression” later on. Shenk reveals the treatments Lincoln endured and his efforts to come to terms with his melancholy, including a poem he published on suicide and his unpublished writings on the value of personal—and national—suffering. By consciously shifting his goal away from personal contentment (which he realized he could not attain) and toward universal justice, Lincoln gained the strength and insight that he, and America, required to transcend profound darkness.

A revelatory synthesis of cultural history and social psychology that shows how one-to-one collaboration drives creative success Weaving the lives of scores of creative duos-from John Lennon and Paul McCartney to Marie and Pierre Curie to Steve Jobs and Steve Wozniak-Joshua Wolf Shenk identifies the core qualities of that dizzying experience we call “chemistry.” Revealing the six essential stages through which creative intimacy unfolds, Shenk draws on new scientific research and builds an argument for the social foundations of creativity-and the pair as its primary embodiment. Along the way, he reveals how pairs begin to talk, think, and even look like each other; how the most successful ones thrive on conflict; and why some pairs flame out while others endure. When it comes to shaping the culture, Shenk argues, two is the magic number, not just because of the dyads behind everything from South Park to the American Civil Rights movement to Starry Night, but because of the nature of creative thinking. Even when we’re alone, we are in a sense “collaborating” with a voice inside our head. At once intuitive and surprising, Powers of Two will change the way we think about innovation.
