Here's a particularly stupid theory. If we take "The Doctor" to
be the Doctor's name - even if it is in the form of a title no
doubt meaning something deep and Gallifreyan - perhaps our
earthly use of the word "doctor" meaning healer or wise man is
direct result of the Doctor's multiple interventions in our
history as a healer and wise man. In other words, we got it from
him. This is a very silly idea and I'm consequently rather proud
of it.
Steven Moffat
Does anyone seriously beleive his name will be revealed to us?
