Soliloquy on the Beacon

Upon discovering that he's arrived on a stasis ship in the distant future, the Doctor gives an impassioned speech about the vessel's nature as proof of humanity's undefeatable perseverance. Of note is that according to the show's production staff, this monologue was written precisely because Tom Baker's deep, theatrical voice lent well to such soliloquies, the kind that previous Doctors would never have been able to pull off.
