In his posthumous and unpublished essays, Oliver Sacks tells us about the scientific and personal passions that accompanied him throughout his life.

In this new book by Oliver Sacks we once again meet his infinite curiosity, his immense erudition and his overflowing personality as a doctor and writer. Its subtitle of "First Loves and Last Writings" perfectly reflects the content of this volume: a journey through the passions and experiences of Sacks's more than eighty years of life, in which he tells us about his first love for chemistry. , museums, libraries, swimming, medicine and, above all, that great enigma that fascinated him throughout his existence, the brain; a compilation of unpublished stories in which we peer into the world of dreams, of instincts, of brain aging, of the destruction of personality, of the forgotten virtues of sanatoriums; a summary also of some of the author's most enduring "loves": herrings, botany, gardens, the book as an object. A work that closes with an essay that is both a testament and a warning to the humanity to come, "Life goes on", where his lucid vision tries to illuminate hope.

Everything in its place is a kind of appendix to his autobiography In Motion: themes outlined in it now appear expanded and branched to end up forming one more piece of that multiple and omnivorous work with which Dr. Sacks, in imitation of his admired Alexander von Humboldt, sought to encompass the versatile and enormous facets of human knowledge.

«The Shakespeare of scientific literature. His writing always brims with blood, life and history »(Bob Grant, The Scientist).

"A book that leaves us with an enormously moving image of its author" (Simon Callow, The New York Review of Books).
