Oliver Sacks Quote

It came upon me sometime in my fifteenth year that I no longer woke up with sudden excitements— Today I will get the Clerici solution! Today I will read about Humphry Davy and electric fish! Today I will finally understand diamagnetism, perhaps! I no longer seemed to get these sudden illuminations, these epiphanies, these excitements which Flaubert (whom I was now reading) called erections of the mind. Erections of the body, yes, this was a new, exotic part of life—but those sudden raptures of the mind, those sudden landscapes of glory and illumination, seemed to have deserted or abandoned me. Or had I, in fact, abandoned them?
