Enhancement not only allows the possibilities of a healthy fullness and exuberance, but of a rather ominous extravagance, aberration, monstrosity ... This danger is built into the very nature of growth and life. Growth can become over-growth, life 'hyper-life' ... The paradox of an illness which can present as wellness - as a wonderful feeling of health and well-being, and only later reveal its malignant potentials - is one of the chimaeras, tricks and ironies of nature.

Music is part of being human.

I regard music therapy as a tool of great power in many neurological disorders -- Parkinson's and Alzheimer's -- because of its unique capacity to organize or reorganize cerebral function when it has been damaged.

The past which is not recoverable in any other way is embedded, as if in amber, in the music, and people can regain a sense of identity.

In terms of brain development, musical performance is every bit as important educationally as reading or writing.

There will be no one like us when we are gone, but then there is no one like anyone else, ever. 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.

About 10 percent of the hearing impaired get musical hallucinations, and about 10 percent of the visually impaired get visual hallucinations.
