Behind the scenes[edit | edit source]

  • Though the original philosophical definition of "sentience" focused on the ability to feel, as distinct from the ability to reason, the term is often used in science-fiction and fantasy to refer to beings possessing consciousness akin to a human's, which is the meaning which seems to be reflected by the term's use in Doctor Who fiction.
