There is no boundary line to art. Music is your own experience, your thoughts, your wisdom. If you don't live it, it won't come out of your horn.

-Parker, Charlie known as  'Bird'
  Quoted in Ross Russell Bird Lives! (1972), pt.4, ch.22.

No man has a right to fix the boundary of the march of a nation. No man has a right to say to his country,'Thus far thou shalt go and no further.'

-Parnell, Charles Stewart
  Speech, Cork, 21 Jan.
