At the center of this book is the relationship of human life with the traumatic experience of loss. What happens inside us when we lose someone we have deeply loved? What void opens up? What work awaits us to return to life? And what happens when this work is impossible and we feel lost together with those we have lost? The work of mourning and nostalgia are two examples of how we can remain close to what we have lost without being swallowed up by pain. While our time exalts the future, the project, the resourcefulness, the mourning and the nostalgia remind us that looking backwards is not always a sign of impotence, but can also fuel the resources needed to be truly capable of never stop to born. Can light come from the past? Can there be light in the dust?
