`  :There's also an episode of Buffy the Vampire Slayer called ``Tabula Rasa``. It's from the show's sixth season, and in it, a spell is cast that causes the characters to lose all memory of their identities (for instance, Buffy forgets she's the Slayer, and decides that she's named ``Joan``). E.g. their mental slates are wiped nearly clean (I say ``nearly`` because they can still walk, etc., and are still able to speak in fluent English, and seeing as language is a learned thing...). The episode's relatively famous in the fandom and is definitely a reference to the psychological philosophy of Aquinas and Aristotle, so it might be well worth noting here. However, you wouldn't want to put it in ``References``, as that's where key sources typically go. ) Perhaps a brief pop culture references section?  `
