Stimulus

Mario: The field of cognitive science is not a genuinely autonomous discipline since it addresses issues also addressed by the disciplines of computer science, linguistics, and psychology. A genuinely of inquiry all its own.

Lucy: Nonsense. You've always acknowledged that philosophy is a genuinely autonomous discipline and that, like most people, you think of philosophy as addressing issues also addressed by the disciplines of linguistics, mathematics, and psychology. A field of study is a genuinely autonomous discipline by virtue of its having its addressing issues that no other field of study addresses.

Answer choices

  1. Out of Scope: questioning expertise0% picked this

    questioning Mario's expertise in cognitive

    Nothing Lucy says sounds like she's challenging Mario's expertise in cognitive science. It's also not like Mario is a cognitive scientist, so it's not even clear why his expertise or lack thereof is relevant to this conversation.

  2. Out of Scope: demonstrate confusion12% picked this

    demonstrating that Mario confuses the notion of a field of study with that of a

    Lucy never explains that Mario has confused one thing for another. Both speakers agree that all genuinely autonomous disciplines are fields of study, but not all fields of study are genuinely autonomous disciplines. Mario is arguing that what turns a field of study into a genuinely autonomous discipline is having unique subject matter, and Lucy is saying, no, what turns a field of study into a genuinely autonomous discipline is having a unique methodology.

  3. Correct80% picked this

    Why this is right

    This is getting at the first half of Lucy's paragraph, the Implications of Logic half. According to his principle, "if genuinely autonomous discipline, then domain of inquiry all its own", Philosophy would not be genuinely autonomous. After all, it doesn't have a domain all its own. It addresses issues also addressed by linguistics, mathematics, and psychology. But this is in conflict with Mario's belief -- "You've always acknowledged that philosophy is a genuinely autonomous discipline". Since we can match this up, it's correct.

    Skill tested: Method · how this choice captures the argument's function is the move to repeat next time.

  4. Out of Scope7% picked this

    disputing the accuracy of Mario's description of cognitive science as addressing issues also addressed

    Out of Scope: disputing description of CS Lucy never once mentions cognitive science, so she definitely didn't dispute Mario's description of what cognitive science covers or where it overlaps with other fields of study.

  5. Out of Scope: establish not philosopher0% picked this

    establishing that Mario is not a

    There's no talk of whether Mario is or isn't a philosopher. She only says, "I know you think philosophy is a genuinely autonomous discipline". That doesn't tell us whether Mario is or isn't himself a philosopher, and Lucy certainly never proves that he isn't.
