Possible worlds

    Words and music by Professor John Worrall

    Saw you there at the Logic lecture

    And I knew I just had to getcha

    There ain't no possible world in which I won't

    There ain't no possible world in which I don't

    It was all 'if p then q'

    But all I saw was 'if it's me then it's you'

    There ain't no possible world in which we won't

    There ain't no possible world in which we don't

    Eyelashes were false, but everything else was real

    And man, you know, I couldn't wait to feel

    Unconditional conjunction on my mind

    And you're gonna be mine in every truth table line

    Yeah you're gonna be mine in every truth table line

    Structural realism blues

    Words and music by Professor John Worrall

    I woke up this morning, science's success on my mind

    I woke up this morning, science's success on my mind

    If you don't believe in miracles, you've gotta be a realist of some kind

    But in the middle of the night, the pessimistic induction got me

    Yeah in the middle of the night, the pessimistic induction got me

    It seems a realist can't handle theory change in history

    So I tossed and I turned till I thought my mind would rupture

    Yeah I tossed and I turned till I thought my mind would rupture

    And then I heard the word, and the word was 'structure'

    I said: think of Fresnel

    think of Maxwell

    Oh my theory fits them so well

    You see the equations

    Are completely preserved

    So come and give structural realism a whirl

    Metaphysics, it comes and it goes

    Yeah, metaphysics, it comes and it goes

    But the content's in the structure,

    And the structure it just grows and grows

    So if you wanna have the very best of both worlds

    Yeah if you wanna have the very best of both worlds

    Come on and give structural realism a whirl.
