“I have been able to see my life as from a great altitude, as a sort of landscape, and with a deepening sense of the connection of all its parts,” visionary neurologist Oliver Sacks wrote in his poignant, beautiful, and courageous farewell to life. In one final gesture of generosity, this cartographer of the mind and its meaning maps the landscape of his remarkable character and career in On the Move: A Life (public library) — an uncommonly moving autobiography, titled after a line from a poem by his dear friend Thom Gunn: “At worst,” wrote Gunn, “one is in motion; and at best, / Reaching no absolute, in which to rest, / One is always nearer by not keeping still.” Sacks’s unstillness is that of a life defined by a compassionate curiosity — about the human mind, about the human spirit, about the invisibilia of our inner lives.
