“When people die, they cannot be replaced. They leave holes that cannot be filled, for it is the fate — the genetic and neural fate — of every human being to be a unique individual, to find his own path, to live his own life, to die his own death.”
― Oliver Sacks

“Very young children love and demand stories, and can understand complex matters presented as stories, when their powers of comprehending general concepts, paradigms, are almost nonexistent.”
― Oliver Sacks, The Man Who Mistook His Wife for a Hat and Other Clinical Tales

“And so was Luria, whose words now came back to me: ‘A man does not consist of memory alone. He has feeling, will, sensibility, moral being ... It is here ... you may touch him, and see a profound change.’ Memory, mental activity, mind alone, could not hold him; but moral attention and action could hold him completely.”

“Astounded—and indifferent—for he was a man who, in effect, had no ‘day before’.”

“...when the brain is released from the constraints of reality, it can generate any sound, image, or smell in its repertoire, sometimes in complex and "impossible" combinations".”

“Thus the feeling I sometimes have - which all of us who work closely with aphasiacs have - that one cannot lie to an aphasiac. He cannot grasp your words, and cannot be deceived by them; but what he grasps he grasps with infallible precision, namely the expression that goes with the words, the total, spontaneous, involuntary expressiveness which can never be simulated or faked, as words alone can, too easily.”

“Dr. Kertesz mentioned to me a case known to him of a farmer who had developed prosopagnosia and in consequence could no longer distinguish (the faces of) his cows, and of another such patient, an attendant in a Natural History Museum, who mistook his own reflection for the diorama of an ape”

“The power of music, narrative and drama is of the greatest practical and theoretical importance. One may see this even in the case of idiots, with IQs below 20 and the extremest motor incompetence and bewilderment. Their uncouth movements may disappear in a moment with music and dancing—suddenly, with music, they know how to move. We see how the retarded, unable to perform fairly simple tasks involving perhaps four or five movements or procedures in sequence, can do these perfectly if they work to music—the sequence of movements they cannot hold as schemes being perfectly holdable as music, i.e. embedded in music. The same may be seen, very dramatically, in patients with severe frontal lobe damage and apraxia—an inability to do things, to retain the simplest motor sequences and programmes, even to walk, despite perfectly preserved intelligence in all other ways. This procedural defect, or motor idiocy, as one might call it, which completely defeats any ordinary system of rehabilitative instruction, vanishes at once if music is the instructor. All this, no doubt, is the rationale, or one of the rationales, of work songs.”

“At the end of our visit, Fleisher agreed to play something on my piano, a beautiful old 1894 Bechstein concert grand that I had grown up with, my father's piano. Fleisher sat at the piano and carefully, tenderly, stretched each finger in turn, and then, with arms and hands almost flat, he started to play. He played a piano transcription of Bach's "Sheep May Safely Graze," as arranged for piano by Egon Petri. Never in its 112 years, I thought, had this piano been played by such a master-I had the feeling that Fleisher has sized up the piano's character and perhaps its idiosyncrasies within seconds, that he had matched his playing to the instrument, to bring out its greatest potential, its particularity. Fleisher seemed to distill the beauty, drop by drop, like an alchemist, into flowing notes of an almost unbearable beauty-and, after this, there was nothing more to be said.”

“One must drop all presuppositions and dogmas and rules - for there only lead to stalemate or disaster; one must cease to regard all patients as replicas, and honor each one with individual reactions and propensities; and, in this way, with the patient as one's equal, one's co-explorer, not one's puppet, one may find therapeutic ways which are better than other ways, tactics which can be modified as occasion requires.”

“The pleasure we obtain from music comes from counting, but counting unconsciously. Music is nothing but unconscious arithmetic.”

“But who was more tragic, or who was more damned—the man who knew it, or the man who did not?”
